Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Business	Description of the Business and Presentation of Financial Statements Calumet Specialty Products Partners, L.P. (the “Company”) is a publicly traded Delaware limited partnership listed on the NASDAQ Global Select Market under the ticker symbol “CLMT.” The general partner of the Company is Calumet GP, LLC, a Delaware limited liability company. As of March 31, 2019 , the Company had 77,469,501 limited partner common units and 1,581,010 general partner equivalent units outstanding. The general partner owns 2% of the Company and all of the incentive distribution rights (as defined in the Company’s partnership agreement), while the remaining 98% is owned by limited partners. The general partner employs all of the Company’s employees and the Company reimburses the general partner for certain of its expenses. The Company is engaged in the production and marketing of crude oil-based specialty products including lubricating oils, white mineral oils, solvents, petrolatums, waxes, and fuel and fuel related products including gasoline, diesel, jet fuel, asphalt and heavy fuel oils. The Company is based in Indianapolis, Indiana and owns specialty and fuel products facilities. The Company owns and leases additional facilities, primarily related to production and marketing of specialty and fuel products, throughout the United States. The unaudited condensed consolidated financial statements of the Company as of March 31, 2019 and for the three months ended March 31, 2019 and 2018 , included herein have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the following disclosures are adequate to make the information presented not misleading. The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These unaudited condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations for the interim periods presented. All adjustments are of a normal nature, unless otherwise disclosed. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s 2018 Annual Report.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Reclassifications Certain amounts in the prior years’ unaudited condensed consolidated financial statements have been reclassified to conform to the current year presentation. Other Current Liabilities Other current liabilities consisted of the following (in millions): March 31, 2019 December 31, 2018 RINs Obligation $ 14.2 $ 15.8 Other (1) 55.9 18.0 Total $ 70.1 $ 33.8 (1) Balance as of March 31, 2019 includes $38.1 million related to the reclassification of the present value of the TexStar finance lease obligation in the first quarter of 2019 from current and long-term debt to other current liabilities. See Note 7 - “ Commitments and Contingencies ” for further information. The Company’s Renewable Identification Numbers (“RINs”) obligation (“RINs Obligation”) represents a liability for the purchase of RINs to satisfy the EPA requirement to blend biofuels into the fuel products it produces pursuant to the EPA’s RFS. RINs are assigned to biofuels produced in the U.S. as required by the EPA. The EPA sets annual quotas for the percentage of biofuels that must be blended into transportation fuels consumed in the U.S. and, as a producer of motor fuels from petroleum, the Company is required to blend biofuels into the fuel products it produces at a rate that will meet the EPA’s annual quota. To the extent the Company is unable to blend biofuels at that rate, it must purchase RINs in the open market to satisfy the annual requirement. The Company’s RINs Obligation is based on the amount of RINs it must purchase and the price of those RINs as of the balance sheet date. The Company uses the inventory model to account for RINs, measuring acquired RINs at weighted-average cost. The cost of RINs used each period is charged to cost of sales with cash inflows and outflows recorded in the operating cash flow section of the unaudited condensed consolidated statements of cash flows. The liability is calculated by multiplying the RINs shortage (based on actual results) by the period end RIN spot price. The Company recognizes an asset at the end of each reporting period in which it has generated RINs in excess of its RINs Obligation. The asset is initially recorded at cost at the time the Company acquires them and are subsequently revalued at the lower of cost or market as of the last day of each accounting period and the resulting adjustments are reflected in costs of sales for the period in the unaudited condensed consolidated statements of operations. The value of RINs in excess of the RINs Obligation, if any, would be reflected in other current assets on the condensed consolidated balance sheets. RINs generated in excess of the Company’s current RINs Obligation may be sold or held to offset future RINs Obligations. Any such sales of excess RINs are recorded in cost of sales in the unaudited condensed consolidated statements of operations. The assets and liabilities associated with the Company’s RINs Obligation are considered recurring fair value measurements. See Note 7 - “ Commitments and Contingencies ” for further information on the Company’s RINs Obligation. Adopted Accounting Pronouncements On January 1, 2019, the Company adopted ASU No. 2016-02 , Leases (Topic 842) (“ASU 2016-02”) and all the related amendments to its lease contracts using the modified retrospective method. The effective date was used as the Company’s date of initial application with no restatement of prior periods. As such, prior periods continue to be reported under the accounting standards in effect for those periods. See Note 14 - “ Leases ” for further information. On January 1, 2019, the Company adopted ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which improves the financial reporting of hedging relationships to better align risk management activities in financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. Given the Company’s current risk management strategy of not designating any of its derivative positions as hedges, the adoption of this guidance had no effect on our consolidated financial statements. If, in the future, the Company decides to modify its hedging strategies, this new accounting guidance would become applicable and will be applied at that time. On January 1, 2019, the Company adopted ASU No. 2018-07, Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). This update simplifies the guidance related to nonemployee share-based payments by superseding ASC 505-50 and expanding the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both nonemployees and employees. Prior to the issuance of this standard update, nonemployee share-based payments were subject to ASC 505-50 requirements while employee shared-based payments were subject to ASC 718 requirements. ASU 2018-07 is effective for fiscal years (including interim periods) beginning after December 15, 2018, with early adoption permitted. The adoption of ASU 2018-07 had no impact on the Company’s consolidated financial statements.

Revenue Recognition Revenue Rec

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The following is a description of principal activities from which the Company generates revenue. Revenues are recognized when control of the promised goods are transferred to the customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods promised within each contract and determines the performance obligations and assesses whether each promised good is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Products The Company is engaged in the production and marketing of crude oil-based specialty products including lubricating oils, solvents, waxes, synthetic lubricants and other products which comprise the specialty products segment. The Company is also engaged in the production of fuel and fuel related products including gasoline, diesel, jet fuel, asphalt and other products which comprise the fuel products segment. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. For each contract, the Company considers the promise to transfer products, each of which are distinct, to be the identified performance obligations. In determining the transaction price, the Company evaluates whether the price is subject to variable consideration such as product returns, rebates or other discounts to determine the net consideration to which the Company expects to be entitled. The Company transfers control and recognizes revenue upon shipment to the customer or, in certain cases, upon receipt by the customer in accordance with contractual terms. Excise and Sales Taxes The Company assesses, collects and remits excise taxes associated with the sale of certain of its fuel products. Furthermore, the Company collects and remits sales taxes associated with certain sales of its products to non-exempt customers. The Company excludes excise taxes and sales taxes that are collected from customers from the transaction price in its contracts with customers. Accordingly, revenue from contracts with customers is net of sales-based taxes that are collected from customers and remitted to taxing authorities. Shipping and Handling Costs Shipping and handling costs are deemed to be fulfillment activities rather than a separate distinct performance obligation. Cost of Obtaining Contracts The Company may incur incremental costs to obtain a sales contract, which under ASC 606 should be capitalized and amortized over the life of the contract. The Company has elected to apply the practical expedient in ASC 340-40-50-5 allowing the Company to expense these costs since the contracts are short-term in nature with a contract term of one year or less. Disaggregation of Revenue The following table reflects the disaggregation of revenue by major source (in millions): Three Months Ended March 31, 2019 2018 Sales by major source Standard specialty products $ 292.3 $ 253.8 Packaged and synthetic specialty products 59.9 68.0 Total specialty products $ 352.2 $ 321.8 Fuel and fuel related products $ 442.9 $ 395.5 Asphalt 56.2 33.2 Total fuel products $ 499.1 $ 428.7 Total sales $ 851.3 $ 750.5 Revenue is recognized when obligations under the terms of a contract with a customer are satisfied; recognition generally occurs with the transfer of control at a point in time. The contract with the customer states the final terms of the sale, including the description, quantity and price of each product or service purchased. For fuel products, payment is typically due in full between 2 to 30 days of delivery or the start of the contract term, such that payment is typically collected 2 to 30 days subsequent to the satisfaction of performance obligations. For specialty products, payment is typically due in full between 30 to 90 days of delivery or the start of the contract term, such that payment is typically collected 30 to 90 days subsequent to the satisfaction of performance obligations. In the normal course of business, the Company does not accept product returns unless the item is defective as manufactured. The expected costs associated with a product assurance warranty continues to be recognized as expense when products are sold. The Company does not offer promised services that could be considered warranties that are sold separately or provide a service in addition to assurance that the related product complies with agreed upon specifications. The Company establishes provisions based on the methods described in ASC 606 for estimated returns and warranties as variable consideration when determining the transaction price. Contract Balances Under product sales contracts, the Company invoices customers for performance obligations that have been satisfied, at which point payment is unconditional. Accordingly, a product sales contract does not give rise to contract assets or liabilities under ASC 606. The Company’s receivables, net of allowance for doubtful accounts, from contracts with customers as of March 31, 2019 and December 31, 2018 was $241.8 million and $177.7 million , respectively. Transaction Price Allocated to Remaining Performance Obligations The Company’s product sales are short-term in nature with a contract term of one year or less. The Company has utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. Additionally, each unit of product generally represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Inventories

Inventories	3 Months Ended
	Mar. 31, 2019
Inventory Disclosure [Abstract]
Inventories	Inventories The cost of inventory is recorded using the last-in, first-out (“LIFO”) method. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs and are subject to the final year-end LIFO inventory valuation. In certain circumstances, the Company may decide not to replenish inventory for certain products or product lines during an interim period, in which case, the Company may record interim LIFO adjustments during that period. During the three months ended March 31, 2019 , the Company recorded increases (exclusive of lower of cost or market (“LCM”) adjustments) of $0.9 million , in cost of sales in the unaudited condensed consolidated statements of operations due to the permanent liquidation of inventory layers. No such activity occurred in the three months ended March 31, 2018 . Costs include crude oil and other feedstocks, labor, processing costs and refining overhead costs. Inventories are valued at the lower of cost or market value. The replacement cost of these inventories, based on current market values, would have been $8.2 million higher and $7.8 million lower as of March 31, 2019 and December 31, 2018 , respectively. On March 31, 2017 and June 19, 2017, the Company sold inventory comprised of crude oil and refined products to Macquarie Energy North America Trading Inc. (“Macquarie”) under Supply and Offtake Agreements as described in Note 8 — “Inventory Financing Agreements” related to the Great Falls and Shreveport refineries, respectively. The crude oil remains in the legal title of Macquarie and is stored in the Company’s refinery storage tanks governed by storage agreements. Legal title to the crude oil passes to the Company at the storage tank outlet for processing into refined products. After processing, Macquarie takes title to the refined products stored in the Company’s storage tanks until sold to third parties. While title to certain inventories will reside with Macquarie, the Supply and Offtake Agreements are accounted for by the Company similar to a product financing arrangement; therefore, the inventories sold to Macquarie will continue to be included in the Company’s condensed consolidated balance sheets until processed and sold to a third party. The Company is obligated to repurchase the inventory in certain scenarios. Inventories consist of the following (in millions): March 31, 2019 December 31, 2018 Titled Inventory Supply and Offtake Agreements (1) Total Titled Inventory Supply and Offtake Agreements (1) Total Raw materials $ 48.8 $ 18.2 $ 67.0 $ 41.8 $ 10.6 $ 52.4 Work in process 36.7 34.8 71.5 40.7 19.2 59.9 Finished goods 119.0 33.6 152.6 127.9 43.9 171.8 $ 204.5 $ 86.6 $ 291.1 $ 210.4 $ 73.7 $ 284.1 (1) Amounts represent LIFO value and do not necessarily represent the value of product financing. Refer to Note 8 - “Inventory Financing Agreements” for further information. Under the LIFO inventory method, the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest acquisition costs. In addition, the use of the LIFO inventory method may result in increases or decreases to cost of sales in years that inventory volumes decline as the result of charging cost of sales with LIFO inventory costs generated in prior periods. In periods of rapidly declining prices, LIFO inventories may have to be written down to market value due to the higher costs assigned to LIFO layers in prior periods. During the three months ended March 31, 2019 and 2018 , the Company recorded decreases of $38.9 million and $3.1 million , respectively, in cost of sales in the unaudited condensed consolidated statements of operations due to the LCM valuation.

(“Q’Max”) of all of the issued and outstanding membership interests in Anchor Drilling Fluids USA, LLC (“Anchor”), for total consideration of approximately $89.6 million (subject to further post-closing adjustments) including a base price of $50.0 million , $14.2 million to be paid at various times over the next two years for net working capital and other items and a 10% equity interest in Fluid Holding Corp. (“FHC”), the parent company of Q’Max (the “Anchor Transaction”). Effective in its fourth quarter of 2017, the Company classified its results of operations for all periods presented to reflect Anchor as a discontinued operation and classified the assets and liabilities of Anchor as discontinued operations. Prior to being reported as discontinued operations, Anchor was included as its own reportable segment as oilfield services. Following the application of certain post-closing adjustments, the adjusted total consideration the Company will receive for the Anchor Transaction is $85.5 million . As of March 31, 2019 and December 31, 2018 , the Company had a $9.1 million and an $11.1 million receivable, respectively, in other accounts receivable in the condensed consolidated balance sheet for the remaining payment of the base price and working capital.

In connection with the Anchor Transaction in November 2017, the Company received an investment in FHC as part of the total consideration for Anchor. FHC provides oilfield services and products to customers globally. The Company’s investment in FHC is a non-marketable equity security without a readily determinable fair value. The Company records this investment without a readily determinable fair value using a measurement alternative which measures the security at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes with a same or similar security from the same issuer. Biosyn Holdings, LLC and Biosynthetic Technologies In February 2018, the Company and The Heritage Group formed Biosyn Holdings, LLC (“Biosyn”) for the purpose of acquiring Biosynthetic Technologies, LLC (“Biosynthetic Technologies”), a startup company which developed an intellectual property portfolio for the manufacture of renewable-based and biodegradable esters. In March 2019, the Company sold its investment in Biosyn to The Heritage Group, a related party, for total proceeds of $5.0 million which was recorded in the “other” component of other income (expense) on the unaudited condensed consolidated statement of operations. Prior to the sale of Biosyn, the Company accounted for its ownership in Biosyn under the equity method of accounting.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, the Company is a party to certain claims and litigation incidental to its business, including claims made by various taxation and regulatory authorities, such as the Internal Revenue Service, the EPA and the U.S. Occupational Safety and Health Administration (“OSHA”), as well as various state environmental regulatory bodies and state and local departments of revenue, as the result of audits or reviews of the Company’s business. In addition, the Company has property, business interruption, general liability and various other insurance policies that may result in certain losses or expenditures being reimbursed to the Company. Environmental The Company conducts crude oil and specialty hydrocarbon refining, blending and terminal operations and such activities are subject to stringent federal, regional, state and local laws and regulations governing worker health and safety, the discharge of materials into the environment and environmental protection. These laws and regulations impose obligations that are applicable to the Company’s operations, such as requiring the acquisition of permits to conduct regulated activities, restricting the manner in which the Company may release materials into the environment, requiring remedial activities or capital expenditures to mitigate pollution from former or current operations, requiring the application of specific health and safety criteria addressing worker protection and imposing substantial liabilities for pollution resulting from its operations. Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil and criminal penalties; the imposition of investigatory, remedial or corrective action obligations or the incurrence of capital expenditures; the occurrence of delays in the permitting, development or expansion of projects and the issuance of injunctive relief limiting or prohibiting Company activities. Moreover, certain of these laws impose joint and several, strict liability for costs required to remediate and restore sites where petroleum hydrocarbons, wastes or other materials have been released or disposed. In addition, new laws and regulations, new interpretations of existing laws and regulations, increased governmental enforcement or other developments, some of which legal requirements are discussed below, could significantly increase the Company’s operational or compliance expenditures. Remediation of subsurface contamination is in process at certain of the Company’s refinery sites and is being overseen by the appropriate state agencies. Based on current investigative and remedial activities, the Company believes that the soil and groundwater contamination at these refineries can be controlled or remediated without having a material adverse effect on the Company’s financial condition. However, such costs are often unpredictable and, therefore, there can be no assurance that the future costs will not become material. Great Falls Refinery In connection with the acquisition of the Great Falls refinery from Connacher Oil and Gas Limited (“Connacher”), the Company became a party to an existing 2002 Refinery Initiative Consent Decree (the “Great Falls Consent Decree”) with the EPA and the Montana Department of Environmental Quality. The material obligations imposed by the Great Falls Consent Decree have been completed. On September 27, 2012, Montana Refining Company, Inc. received a final Corrective Action Order on Consent, replacing the refinery’s previously held hazardous waste permit. This Corrective Action Order on Consent governs the investigation and remediation of contamination at the Great Falls refinery. The Company believes the majority of damages related to such contamination at the Great Falls refinery are covered by a contractual indemnity provided by a subsidiary of HollyFrontier Corporation (the “Seller”), the owner and operator of the Great Falls refinery prior to its acquisition by Connacher, under an asset purchase agreement between the Seller and Connacher, pursuant to which Connacher acquired the Great Falls refinery. Under this asset purchase agreement, the Seller agreed to indemnify Connacher and Montana Refining Company, Inc., subject to timely notification, certain conditions and certain monetary baskets and caps, for environmental conditions arising under the Seller’s ownership and operation of the Great Falls refinery and existing as of the date of sale to Connacher. During 2014, the Seller provided the Company a notice challenging the Company’s position that the Seller is obligated to indemnify the Company’s remediation expenses for environmental conditions to the extent arising under the Seller’s ownership and operation of the refinery and existing as of the date of sale to Connacher, which expenditures totaled in excess of $16.1 million as of March 31, 2019 , of which $14.6 million was capitalized into the cost of the Company’s refinery expansion project and the remainder was expensed. The Company continues to believe that the Seller is responsible to indemnify the Company for the majority of these remediation expenses disputed by the Seller and on September 22, 2015, the Company initiated a lawsuit against the Seller. On November 24, 2015, the Seller filed a motion to dismiss the case pending arbitration. On February 10, 2016, the court ordered that all of the claims be addressed in arbitration. The arbitration panel conducted the first phase of the arbitration in July 2018 and issued its ruling on September 13, 2018. In its ruling, the arbitration panel confirmed that the Seller retained the liability for all pre-closing contamination with respect to third-party claims indefinitely and with respect to first party claims for which the Seller received notice within five years after the sale of the refinery, which claims are as subject to the requirements otherwise set forth in the asset purchase agreement. The second phase of the arbitration regarding damages occurred in April 2019 and the Company expects a decision from the arbitration panel in the coming months. In the event the Company is unsuccessful in the legal dispute with the Seller, the Company will be responsible for the remediation expenses. The Company expects that it may incur costs to remediate other environmental conditions at the Great Falls refinery. The Company currently believes that these other costs it may incur will not be material to its financial position or results of operations. Renewable Identification Numbers Obligation In March 2018, the EPA granted the Company’s fuel products refineries a “small refinery exemption” under the RFS for the compliance year 2017, as provided for under the federal Clean Air Act, as amended (“CAA”). In granting those exemptions, the EPA in consultation with the Department of Energy determined that for the compliance year 2017, compliance with the RFS would represent a “disproportionate economic hardship” for these small refineries. The Company is currently awaiting the EPA’s decision as to whether it will be granted a “small refinery exemption” in the current year for the compliance year 2018. The RINs exemptions resulted in a decrease in the RINs Obligation and is charged to cost of sales in the unaudited condensed consolidated statement of operations with the exception of the portion related to the Superior Refinery which was charged to other (income) expense within operating income in the unaudited condensed consolidated statement of operations. As of March 31, 2019 and December 31, 2018 , the Company had a RINs Obligation of $14.2 million and $15.8 million , respectively. Occupational Health and Safety The Company is subject to various laws and regulations relating to occupational health and safety, including the federal Occupational Safety and Health Act, as amended, and comparable state laws. These laws and regulations strictly govern the protection of the health and safety of employees. In addition, OSHA’s hazard communication standard, the EPA’s community right-to-know regulations under Title III of CERCLA and similar state statutes require the Company to maintain information about hazardous materials used or produced in the Company’s operations and provide this information to employees, contractors, state and local government authorities and customers. The Company maintains safety and training programs as part of its ongoing efforts to promote compliance with applicable laws and regulations. The Company conducts periodic audits of Process Safety Management systems at each of its locations subject to this standard. The Company’s compliance with applicable health and safety laws and regulations has required, and continues to require, substantial expenditures. Changes in occupational safety and health laws and regulations or a finding of non-compliance with current laws and regulations could result in additional capital expenditures or operating expenses, as well as civil penalties and, in the event of a serious injury or fatality, criminal charges. Labor Matters The Company has employees covered by various collective bargaining agreements. The below facilities ratified their collective bargaining agreements during the three months ended March 31, 2019 and extended the agreements through the below expiration dates: Facility/ Refinery Union Expiration Date Cotton Valley International Union of Operating Engineers January 15, 2023 Shreveport United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied-Industrial and Service Workers International Union April 30, 2022 Missouri United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied-Industrial and Service Workers International Union April 30, 2022 Great Falls United Steel, Paper and Forestry, Rubber, Manufacturing, Energy Allied-Industrial and Service Workers International Union July 31, 2022 Other Matters, Claims and Legal Proceedings The Company was a party to a 2014 Throughput and Deficiency Agreement with TexStar Midstream Logistics, L.P. (“TexStar”) pursuant to which TexStar delivered crude oil to the Company’s San Antonio refinery through a crude oil pipeline system owned and operated by TexStar (the “Pipeline Agreement”). The Pipeline Agreement had an initial term of 20 years and was accounted for as a finance lease on the Company’s condensed consolidated balance sheets. TexStar and the Company have each terminated the Pipeline Agreement for alleged breaches of the agreement. The Company ceased using the asset as of February 28, 2019, wrote off the associated net book value of $10.7 million as impairment and disposal of assets and reclassified the $38.1 million present value of financing lease obligation from current and long-term debt to other current liabilities on the condensed consolidated balance sheet. The Company is in dispute with TexStar over whether any additional monies are owed with TexStar claiming certain minimum amounts of $0.0 - $0.5 million a month continued to be owed through the remainder of the original term of the Pipeline Agreement. The Company believes it will prevail in a dispute over whether further payments are owed, but pending resolution, the Company has chosen to keep the $38.1 million liability on its condensed consolidated balance sheets. On October 31, 2018, the Company received an indemnity claim notice (the “Claim Notice”) from Husky Superior Refining Holding Corp. (“Husky”) under the Membership Interest Purchase Agreement, dated August 11, 2017 (the “MIPA”), which was entered into in connection with the disposition of the Superior Refinery. The Claim Notice relates to alleged losses Husky incurred in connection with a fire at the Husky Superior refinery on April 26, 2018, over five months after Calumet sold Husky 100% of the membership interests in the entity that owns the Husky Superior refinery. Calumet understands the fire occurred during a turnaround of the Husky Superior refinery at a time when Husky owned, operated, and supervised the refinery. Calumet was not involved with the turnaround. The U.S. Chemical Safety and Hazard Investigation Board (“CSB”) is currently investigating the fire but has not contacted Calumet in connection with that investigation or suggested that Calumet is responsible for the fire. Husky’s Claim Notice alleges that Husky “has become aware of facts which may give rise to losses” for which it reserved the right to seek indemnification at a later date. The Claim Notice further alleges breaches of certain representations, warranties, and covenants contained in the MIPA. The information currently publicly available about the fire and the CSB investigation does not support Husky’s threatened claims, and Husky has not filed a lawsuit against Calumet. If Husky were to seek recourse under the MIPA for such claims, they would be subject to certain limits on indemnification liability that may reduce or eliminate any potential indemnification liability. On May 4, 2018, the SEC requested that the Company and certain of its executives voluntarily produce certain communications and documents prepared or maintained from January 2017 to May 2018 and generally related to the Company’s finance and accounting staff, financial reporting, public disclosures, accounting policies, disclosure controls and procedures and internal controls. Beginning on July 11, 2018, the SEC issued several subpoenas formally requesting the same documents previously subject to the voluntary production requests by the SEC as well as additional, related documents and information. The SEC has also interviewed and taken testimony from current and former Company employees and other individuals and may elect to conduct further interviews in the future. The Company has, from the outset, cooperated with the SEC’s requests and intends to continue to do so. Currently, the Company cannot estimate the timing, or ultimate outcome, including financial impact, if any, resulting from the SEC’s investigation. The Company is subject to other matters, claims and litigation incidental to its business. The Company has recorded accruals with respect to certain of its matters, claims and litigation where appropriate, that are reflected in the unaudited condensed consolidated financial statements but are not individually considered material. For other matters, claims and litigation, the Company has not recorded accruals because it has not yet determined that a loss is probable or because the amount of loss cannot be reasonably estimated. While the ultimate outcome of matters, claims and litigation currently pending cannot be determined, the Company currently does not expect these outcomes, individually or in the aggregate (including matters for which the Company has recorded accruals), to have a material adverse effect on its financial position, results of operations or cash flows. The outcome of any matter, claim or litigation is inherently uncertain, however and if decided adversely to the Company, or if the Company determines that settlement of particular litigation is appropriate, the Company may be subject to liability that could have a material adverse effect on its financial position, results of operations or cash flows. Standby Letters of Credit The Company has agreements with various financial institutions for standby letters of credit, which have been issued primarily to vendors. As of March 31, 2019 and December 31, 2018 , the Company had outstanding standby letters of credit of $35.7 million and $35.1 million , respectively, under its revolving credit facility. Refer to Note 9 - “ Long-Term Debt ” for additional information regarding the Company’s revolving credit facility. At March 31, 2019 and December 31, 2018 , the maximum amount of letters of credit the Company could issue under its revolving credit facility was subject to borrowing base limitations, with a maximum letter of credit sublimit equal to $300.0 million , which amount may be increased with the consent of the Agent (as defined in the revolving credit facility agreement) to 90% of revolver commitments then in effect ( $600.0 million at March 31, 2019 and December 31, 2018 ).

Inventory Financing Agreement

Other Commitments [Abstract]
Inventory Financing Agreement	Inventory Financing Agreements On March 31, 2017 , the Company entered into several agreements with Macquarie to support the operations of the Great Falls refinery (the “Great Falls Supply and Offtake Agreements”). The Great Falls Supply and Offtake Agreements expire on September 30, 2019 . On July 27, 2017, the Company amended the Great Falls Supply and Offtake Agreements to provide Macquarie the option to terminate the Great Falls Supply and Offtake Agreements with nine months’ notice any time prior to June 2019 and the Company the option to terminate with ninety days’ notice at any time. On June 19, 2017, the Company entered into several agreements with Macquarie to support the operations of the Shreveport refinery (the “Shreveport Supply and Offtake Agreements” and together with the Great Falls Supply and Offtake Agreements, the “Supply and Offtake Agreements”). The Shreveport Supply and Offtake Agreements expire on June 30, 2020; however, Macquarie has the option to terminate the Shreveport Supply and Offtake Agreements with nine months’ notice any time prior to June 2019 and the Company has the option to terminate with ninety days’ notice at any time. Subsequent to March 31, 2019, the Supply and Offtake Agreements were amended to extend their expiration dates, among other things. See Note 15 - “Subsequent Events” for further discussion. During the terms of the Supply and Offtake Agreements, the Company may purchase crude oil from Macquarie or one of its affiliates. Per the Supply and Offtake Agreements, Macquarie will provide up to 30,000 barrels per day of crude oil to the Great Falls refinery and 60,000 barrels per day of crude oil to the Shreveport refinery. The Company agreed to purchase the crude oil on a just-in-time basis to support the production operations at the Great Falls and Shreveport refineries. Additionally, the Company agreed to sell, and Macquarie agreed to buy, at market prices, refined products produced at the Great Falls and Shreveport refineries. For Shreveport, finished products consisting of finished fuel products (other than jet fuel), lubricants and waxes, Macquarie may (but is not required to) sell such products to the sales intermediation party (“SIP”), and the SIP may (but is not required to) sell such products to Shreveport, as applicable, for sale in turn to third parties. For jet fuel and certain intermediate products, Macquarie may (but is not required to) sell such products to Shreveport for sale thereby to third parties. The Company will then repurchase the refined products from Macquarie or the SIP prior to selling the refined products to third parties. The Supply and Offtake Agreements are subject to minimum and maximum inventory levels. The agreements also provide for the lease to Macquarie of crude oil and certain refined product storage tanks located at the Great Falls and Shreveport refineries and certain offsite locations. Following expiration or termination of the agreements, Macquarie has the option to require the Company to purchase the crude oil and refined product inventories then owned by Macquarie and located at the leased storage tanks at then current market prices. In addition, barrels owned by the Company are pledged as collateral to support the Deferred Payment Arrangement (defined below) obligations under these agreements. While title to certain inventories will reside with Macquarie, the Supply and Offtake Agreements are accounted for by the Company similar to a product financing arrangement; therefore, the inventories sold to Macquarie will continue to be included in the Company’s condensed consolidated balance sheets until processed and sold to a third party. Each reporting period, the Company will record liabilities in an amount equal to the amount the Company expects to pay to repurchase the inventory held by Macquarie based on market prices at the termination date included in obligations under inventory financing agreements in the condensed consolidated balance sheets. The Company has determined that the redemption feature on the initially recognized liabilities related to the Supply and Offtake Agreements is an embedded derivative indexed to commodity prices. As such, the Company has accounted for these embedded derivatives at fair value with changes in the fair value, if any, recorded in gain (loss) on derivative instruments in the Company’s unaudited condensed consolidated statements of operations. For more information on the valuation of the associated derivatives, see Note 10 - “ Derivatives ” and Note 11 - “ Fair Value Measurements .” The embedded derivatives will be recorded in obligations under inventory financing agreements on the condensed consolidated balance sheets. The cash flow impact of the embedded derivatives will be classified as a change in inventory financing activity in the financing activities section in the unaudited condensed consolidated statements of cash flows. For the three months ended March 31, 2019 and 2018 , the Company incurred $1.8 million and $1.7 million , respectively, for financing costs related to the Supply and Offtake Agreements and is included in interest expense in the Company’s unaudited condensed consolidated statements of operations. The Company has provided collateral of $9.5 million related to the initial purchase of the Great Falls and Shreveport inventory to cover credit risk for future crude oil deliveries and potential liquidation risk if Macquarie exercises its rights and sells the inventory to third parties. The collateral was recorded as a reduction to the obligations under inventory financing agreements pursuant to a master netting agreement. The Supply and Offtake Agreements also include a deferred payment arrangement (“Deferred Payment Arrangement”) whereby the Company can defer payments on just-in-time crude oil purchases from Macquarie owed under the agreements up to the value of the collateral provided ( 90% of the collateral inventory). The deferred amounts under the Deferred Payment Arrangement will bear interest at a rate equal to the London Interbank Offered Rate (“LIBOR”) plus 3.25% per annum for both Shreveport and Great Falls. Amounts outstanding under the Deferred Payment Arrangement are included in obligations under inventory financing agreements in the Company’s condensed consolidated balance sheets. Changes in the amount outstanding under the Deferred Payment Arrangement are included within cash flows from financing activities on the unaudited condensed consolidated statements of cash flows. As of March 31, 2019 and December 31, 2018 , the capacity of the Deferred Payment Arrangement was $26.2 million and $21.9 million , respectively, and the Company had $26.8 million and $20.4 million deferred payments outstanding, respectively. In addition to the Deferred Payment Arrangement, Macquarie has advanced the Company an additional $5.0 million which remains outstanding as of March 31, 2019 .

In conjunction with the repurchases, the Company recorded a gain from debt extinguishment of $0.4 million . In April 2019, the Company repurchased an additional $26.8 million of its 2021 Notes. See Note 15 - “Subsequent Events” for further discussion. 2021 Notes, 2022 Notes and 2023 Notes In accordance with SEC Rule 3-10 of Regulation S-X, unaudited condensed consolidated financial statements of non-guarantors are not required. The Company has no assets or operations independent of its subsidiaries. Obligations under its 2021, 2022 and 2023 Notes are fully and unconditionally and jointly and severally guaranteed on a senior unsecured basis by the Company’s current 100%-owned operating subsidiaries and certain of the Company’s future operating subsidiaries, with the exception of the Company’s “minor” subsidiaries (as defined by Rule 3-10 of Regulation S-X), including Calumet Finance Corp. (100%-owned Delaware corporation that was organized for the sole purpose of being a co-issuer of certain of the Company’s indebtedness, including the 2021, 2022 and 2023 Notes). There are no significant restrictions on the ability of the Company or subsidiary guarantors for the Company to obtain funds from its subsidiary guarantors by dividend or loan. None of the subsidiary guarantors’ assets represent restricted assets pursuant to SEC Rule 4-08(e)(3) of Regulation S-X. The 2021, 2022 and 2023 Notes are subject to certain automatic customary releases, including the sale, disposition or transfer of capital stock or substantially all of the assets of a subsidiary guarantor, designation of a subsidiary guarantor as unrestricted in accordance with the applicable indenture, exercise of legal defeasance option or covenant defeasance option, liquidation or dissolution of the subsidiary guarantor and a subsidiary guarantor ceases to both guarantee other Company debt and to be an obligor under the revolving credit facility. The Company’s operating subsidiaries may not sell or otherwise dispose of all or substantially all of their properties or assets to, or consolidate with or merge into, another company if such a sale would cause a default under the indentures governing the 2021, 2022 and 2023 Notes. The indentures governing the 2021, 2022 and 2023 Notes contain covenants that, among other things, restrict the Company’s ability and the ability of certain of the Company’s subsidiaries to: (i) sell assets; (ii) pay distributions on, redeem or repurchase the Company’s common units or redeem or repurchase its subordinated debt; (iii) make investments; (iv) incur or guarantee additional indebtedness or issue preferred units; (v) create or incur certain liens; (vi) enter into agreements that restrict distributions or other payments from the Company’s restricted subsidiaries to the Company; (vii) consolidate, merge or transfer all or substantially all of the Company’s assets; (viii) engage in transactions with affiliates and (ix) create unrestricted subsidiaries. These covenants are subject to important exceptions and qualifications. At any time when the 2021, 2022 and 2023 Notes are rated investment grade by either Moody’s Investors Service, Inc. (“Moody’s”) or S&P Global Ratings (“S&P”) and no Default or Event of Default, each as defined in the indentures governing the 2021, 2022 and 2023 Notes, has occurred and is continuing, many of these covenants will be suspended. As of March 31, 2019 , the Company’s Fixed Charge Coverage Ratio (as defined in the indentures governing the 2021, 2022 and 2023 Notes) was 2.0 . As of March 31, 2019 , the Company was in compliance with all covenants under the indentures governing the 2021, 2022 and 2023 Notes. Third Amended and Restated Senior Secured Revolving Credit Facility On February 23, 2018 , the Company entered into a third amended and restated senior secured revolving credit facility which provides maximum availability of credit under the revolving credit facility of $600.0 million , subject to borrowing base limitations, and includes a $500.0 million incremental uncommitted expansion feature. The revolving credit facility includes a $25.0 million senior secured first loaned in and last to be repaid out (“FILO”) revolving credit facility limited by a FILO borrowing base calculation. The FILO commitment reduces ratably each quarter starting in November 2019 and ending in August 2020. The reductions in FILO commitments convert to revolving credit facility base commitments over the same period. Lenders under the revolving credit facility have a first priority lien on, among other things, the Company’s accounts receivable and inventory and substantially all of its cash. The revolving credit facility, which is the Company’s primary source of liquidity for cash needs in excess of cash generated from operations, matures in February 2023 and bears interest at a rate equal to prime plus a basis points margin or LIBOR plus a basis points margin, at the Company’s option. The margin can fluctuate quarterly based on the Company’s average availability for additional borrowings under the revolving credit facility in the preceding calendar quarter as follows: Base Loans FILO Loans Quarterly Average Availability Percentage Prime Rate Margin LIBOR Rate Margin Prime Rate Margin LIBOR Rate Margin ≥ 66% 0.50% 1.50% 1.50% 2.50% ≥ 33% and < 66% 0.75% 1.75% 1.75% 2.75% < 33% 1.00% 2.00% 2.00% 3.00% As of March 31, 2019 , the margin was 50 basis points for prime rate based revolver loans, 150 basis points for LIBOR based revolver loans, 150 basis points for prime rate based FILO loans and 250 basis points for LIBOR based FILO loans. In addition, if the Leverage Ratio (as defined in the revolving credit facility agreement) is less than 5.5 to 1.0 for any four fiscal quarter periods ending on or after August 23, 2018 , then, after such fiscal quarter, the margins otherwise applicable will be reduced by 25 basis points. Letters of credit issued under the revolving credit facility accrue fees at a rate equal to the margin (measured in basis points) applicable to LIBOR revolver loans. In addition to paying interest quarterly on outstanding borrowings under the revolving credit facility, the Company is required to pay a commitment fee to the lenders under the revolving credit facility with respect to the unutilized commitments thereunder at a rate equal to 0.250% or 0.375% per annum depending on the average daily available unused borrowing capacity for the preceding month. The Company also pays a customary letter of credit fee, including a fronting fee of 0.125% per annum of the stated amount of each outstanding letter of credit, and customary agency fees. In addition, the revolving credit facility contains various covenants that limit, among other things, the Company’s ability to: incur indebtedness; grant liens; dispose of certain assets; make certain acquisitions and investments; redeem or prepay other debt or make other restricted payments such as distributions to unitholders; enter into transactions with affiliates; and enter into a merger, consolidation or sale of assets. Further, the revolving credit facility contains one springing financial covenant which provides that only if the Company’s availability under the revolving credit facility falls below the sum of the greater of (i) 10% of the Borrowing Base (as defined in the revolving credit facility agreement) then in effect and (ii) $35.0 million (which amount is subject to increase in proportion to revolving commitment increases), plus the amount of FILO Loans outstanding, then the Company will be required to maintain as of the end of each fiscal quarter a Fixed Charge Coverage Ratio (as defined in the revolving credit facility agreement) of at least 1.0 to 1.0. As of March 31, 2019 , the Company was in compliance with all covenants under the revolving credit facility. Maturities of Long-Term Debt As of March 31, 2019 , principal payments on debt obligations and future minimum rentals on finance lease obligations are as follows (in millions): Year Maturity 2019 $ 1.7 2020 1.8 2021 879.4 2022 350.3 2023 325.4 Thereafter 1.4 Total $ 1,560.0

Derivatives	Derivatives The Company is exposed to price risks due to fluctuations in the price of crude oil, refined products (primarily in the Company’s fuel products segment), natural gas and precious metals. The Company uses various strategies to reduce its exposure to commodity price risk. The strategies to reduce the Company’s risk utilize both physical forward contracts and financially settled derivative instruments, such as swaps, collars, options and futures, to attempt to reduce the Company’s exposure with respect to: • crude oil purchases and sales; • fuel product sales and purchases; • natural gas purchases; • precious metals purchases; and • fluctuations in the value of crude oil between geographic regions and between the different types of crude oil such as New York Mercantile Exchange West Texas Intermediate (“NYMEX WTI”), Light Louisiana Sweet, Western Canadian Select (“WCS”), WTI Midland, Mixed Sweet Blend and ICE Brent. The Company manages its exposure to commodity markets, credit, volumetric and liquidity risks to manage its costs and volatility of cash flows as conditions warrant or opportunities become available. These risks may be managed in a variety of ways that may include the use of derivative instruments. Derivative instruments may be used for the purpose of mitigating risks associated with an asset, liability and anticipated future transactions and the changes in fair value of the Company’s derivative instruments will affect its earnings and cash flows; however, such changes should be offset by price or rate changes related to the underlying commodity or financial transaction that is part of the risk management strategy. The Company does not speculate with derivative instruments or other contractual arrangements that are not associated with its business objectives. Speculation is defined as increasing the Company’s natural position above the maximum position of its physical assets or trading in commodities, currencies or other risk bearing assets that are not associated with the Company’s business activities and objectives. The Company’s positions are monitored routinely by a risk management committee to ensure compliance with its stated risk management policy and documented risk management strategies. All strategies are reviewed on an ongoing basis by the Company’s risk management committee, which will add, remove or revise strategies in anticipation of changes in market conditions and/or its risk profiles. Such changes in strategies are to position the Company in relation to its risk exposures in an attempt to capture market opportunities as they arise. The Company is obligated to repurchase crude oil and refined products from Macquarie at the termination of the Supply and Offtake Agreements in certain scenarios. The Company has determined that the redemption feature on the initially recognized liability related to the Supply and Offtake Agreements is an embedded derivative indexed to commodity prices. As such, the Company has accounted for these embedded derivatives at fair value with changes in the fair value, if any, recorded in gain (loss) on derivative instruments in the Company’s unaudited condensed consolidated statement of operations. The Company recognizes all derivative instruments at their fair values (see Note 11 - “ Fair Value Measurements ”) as either current assets or current liabilities in the condensed consolidated balance sheets. Fair value includes any premiums paid or received and unrealized gains and losses. Fair value does not include any amounts receivable from or payable to counterparties, or collateral provided to counterparties. Derivative asset and liability amounts with the same counterparty are netted against each other for financial reporting purposes in accordance with the provisions of our master netting arrangements. The following tables summarize the Company’s gross fair values of its derivative instruments, presenting the impact of offsetting derivative assets in the Company’s condensed consolidated balance sheets (in millions): March 31, 2019 December 31, 2018 Balance Sheet Location Gross Amounts of Recognized Assets Gross Amounts Offset in the Condensed Consolidated Balance Sheets Net Amounts of Assets Presented in the Condensed Consolidated Balance Sheets Gross Amounts of Recognized Assets Gross Amounts Offset in the Condensed Consolidated Balance Sheets Net Amounts of Assets Presented in the Condensed Consolidated Balance Sheets Derivative instruments not designated as hedges: Specialty products segment: Midland crude oil basis swaps Derivative assets $ 0.5 $ — $ 0.5 $ 1.0 $ — $ 1.0 Fuel products segment: Inventory financing obligation Obligations under inventory financing agreements $ — $ — $ — $ 1.5 $ — $ 1.5 WCS crude oil basis swaps Derivative assets 17.7 (6.3 ) 11.4 16.5 (1.6 ) 14.9 WCS crude oil percentage basis swaps Derivative assets 8.0 (6.9 ) 1.1 — (6.1 ) (6.1 ) Midland crude oil basis swaps Derivative assets 5.0 — 5.0 7.1 — 7.1 Diesel crack spread swap Derivative assets 6.6 — 6.6 7.4 — 7.4 Diesel percentage basis crack spread swap Derivative assets 3.8 — 3.8 — (6.0 ) (6.0 ) Total derivative instruments $ 41.6 $ (13.2 ) $ 28.4 $ 33.5 $ (13.7 ) $ 19.8 The following tables summarize the Company’s gross fair values of its derivative instruments, presenting the impact of offsetting derivative liabilities in the Company’s condensed consolidated balance sheets (in millions): March 31, 2019 December 31, 2018 Balance Sheet Location Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Condensed Consolidated Balance Sheets Net Amounts of Liabilities Presented in the Condensed Consolidated Balance Sheets Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Condensed Consolidated Balance Sheets Net Amounts of Liabilities Presented in the Condensed Consolidated Balance Sheets Derivative instruments not designated as hedges: Fuel products segment: Inventory financing obligation Obligations under inventory financing agreements $ (11.2 ) $ — (11.2 ) $ — $ — $ — WCS crude oil basis swaps Derivative liabilities (6.3 ) 6.3 — (1.6 ) 1.6 — WCS crude oil percentage basis swaps Derivative liabilities (6.9 ) 6.9 — (6.1 ) 6.1 — Diesel percentage basis crack spread swaps Derivative liabilities — — — (6.0 ) 6.0 — Total derivative instruments $ (24.4 ) $ 13.2 $ (11.2 ) $ (13.7 ) $ 13.7 $ — The Company is exposed to credit risk in the event of nonperformance by its counterparties on these derivative transactions. The Company does not expect nonperformance on any derivative instruments, however, no assurances can be provided. The Company’s credit exposure related to these derivative instruments is represented by the fair value of contracts reported as derivative assets. As of March 31, 2019 , the Company had three counterparties in which the derivatives held were in net assets totaling $28.4 million . As of December 31, 2018 , the Company had four counterparties in which the derivatives held were net assets. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings. The Company primarily executes its derivative instruments with large financial institutions that have ratings of at least A3 and BBB+ by Moody’s and S&P, respectively. In the event of default, the Company would potentially be subject to losses on derivative instruments with mark-to-market gains. The Company requires collateral from its counterparties when the fair value of the derivatives exceeds agreed-upon thresholds in its master derivative contracts with these counterparties. No such collateral was held by the Company as of March 31, 2019 or December 31, 2018 . Collateral received from counterparties is reported in other current liabilities, and collateral held by counterparties is reported in prepaid expenses and other current assets on the Company’s condensed consolidated balance sheets and is not netted against derivative assets or liabilities. Any outstanding collateral is released to the Company upon settlement of the related derivative instrument liability. As of March 31, 2019 and December 31, 2018 , the Company had provided no collateral to its counterparties. Certain of the Company’s outstanding derivative instruments are subject to credit support agreements with the applicable counterparties which contain provisions setting certain credit thresholds above which the Company may be required to post agreed-upon collateral, such as cash or letters of credit, with the counterparty to the extent that the Company’s mark-to-market net liability, if any, on all outstanding derivatives exceeds the credit threshold amount per such credit support agreement. The majority of the credit support agreements covering the Company’s outstanding derivative instruments also contain a general provision stating that if the Company experiences a material adverse change in its business, in the reasonable discretion of the counterparty, the Company’s credit threshold could be lowered by such counterparty. The Company does not expect that it will experience a material adverse change in its business. The cash flow impact of the Company’s derivative activities is classified primarily as a change in derivative activity in the operating activities section in the unaudited condensed consolidated statements of cash flows. Derivative Instruments Not Designated as Hedges For derivative instruments not designated as hedges, the change in fair value of the asset or liability for the period is recorded to gain (loss) on derivative instruments in the unaudited condensed consolidated statements of operations. Upon the settlement of a derivative not designated as a hedge, the gain or loss at settlement is recorded to gain (loss) on derivative instruments in the unaudited condensed consolidated statements of operations. The Company has entered into gasoline swaps, diesel swaps and certain crude oil basis swaps that do not qualify as cash flow hedges for accounting purposes as they were not entered into simultaneously with a corresponding NYMEX WTI derivative contract. However, these instruments provide economic hedges of the Company’s crude oil purchases and gasoline and diesel sales. The Company recorded the following gains (losses) in its unaudited condensed consolidated statements of operations, related to its derivative instruments not designated as hedges (in millions): Type of Derivative Amount of Realized Gain (Loss) Recognized in Gain (Loss) on Derivative Instruments Amount of Unrealized Gain (Loss) Recognized in Gain (Loss) on Derivative Instruments Three Months Ended March 31, Three Months Ended March 31, 2019 2018 2019 2018 Specialty products segment: Midland crude oil basis swaps 1.1 — (0.5 ) — Fuel products segment: Inventory financing obligation — — (12.7 ) (4.0 ) Crude oil swaps — — — (0.3 ) WCS crude oil basis swaps 3.6 — (3.5 ) — WCS crude oil percentage basis swaps 0.1 — 7.2 0.3 Midland crude oil basis swaps 7.3 — (2.1 ) — Gasoline swaps — — — 0.2 Gasoline crack spread swaps — (1.0 ) — 1.8 Diesel swaps — — — 0.2 Diesel crack spread swaps 0.7 (1.1 ) (0.8 ) 4.2 Diesel percentage basis crack spread swaps (1.1 ) — 9.8 (0.4 ) Total $ 11.7 $ (2.1 ) $ (2.6 ) $ 2.0 Derivative Positions WCS Crude Oil Basis Swap Contracts The Company has entered into crude oil basis swaps to mitigate the risk of future changes in pricing differentials between WCS and NYMEX WTI.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. Observable inputs are from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. These tiers include the following: • Level 1 — inputs include observable unadjusted quoted prices in active markets for identical assets or liabilities • Level 2 — inputs include other than quoted prices in active markets that are either directly or indirectly observable • Level 3 — inputs include unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions In determining fair value, the Company uses various valuation techniques and prioritizes the use of observable inputs. The availability of observable inputs varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded and other characteristics particular to the instrument. For many financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants and the valuation does not require significant management judgment. For other financial instruments, pricing inputs are less observable in the marketplace and may require management judgment. Recurring Fair Value Measurements Derivative Assets and Liabilities Derivative instruments are reported in the accompanying unaudited condensed consolidated financial statements at fair value. The Company’s derivative instruments consist of over-the-counter contracts, which are not traded on a public exchange. Substantially all of the Company’s derivative instruments are with counterparties that have long-term credit ratings of at least A3 and BBB+ by Moody’s and S&P, respectively. Commodity derivative instruments are measured at fair value using a market approach. To estimate the fair values of the Company’s commodity derivative instruments, the Company uses the forward rate, the strike price, contractual notional amounts, the risk free rate of return and contract maturity. Various analytical tests are performed to validate the counterparty data. The fair values of the Company’s derivative instruments are adjusted for nonperformance risk and creditworthiness of the counterparty through the Company’s credit valuation adjustment (“CVA”). The CVA is calculated at the counterparty level utilizing the fair value exposure at each payment date and applying a weighted probability of the appropriate survival and marginal default percentages. The Company uses the counterparty’s marginal default rate and the Company’s survival rate when the Company is in a net asset position at the payment date and uses the Company’s marginal default rate and the counterparty’s survival rate when the Company is in a net liability position at the payment date. As a result of applying the applicable CVA at March 31, 2019 and December 31, 2018 , the Company’s net assets and net liabilities changed, in each case, by an immaterial amount. Observable inputs utilized to estimate the fair values of the Company’s derivative instruments were based primarily on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Based on the use of various unobservable inputs, principally non-performance risk, creditworthiness of the counterparties and unobservable inputs in the forward rate, the Company has categorized these derivative instruments as Level 3. Significant increases (decreases) in any of those unobservable inputs in isolation would result in a significantly lower (higher) fair value measurement. The Company believes it has obtained the most accurate information available for the types of derivative instruments it holds. See Note 10 - “ Derivatives ” for further information on derivative instruments. Pension Assets Pension assets are reported at fair value in the accompanying unaudited condensed consolidated financial statements. At March 31, 2019 , the Company’s investments associated with its pension plan primarily consisted of mutual funds. The mutual funds are valued at the net asset value of shares in each fund held by the Pension Plan at quarter end as provided by the respective investment sponsors or investment advisers. Plan investments can be redeemed within a short time frame (approximately 10 business days), if requested. Liability Awards Unit based compensation liability awards are awards that are expected to be settled in cash on their vesting dates, rather than in equity units (“Liability Awards”). The Liability Awards are categorized as Level 1 because the fair value of the Liability Awards is based on the Company’s quoted closing unit price as of each balance sheet date. Renewable Identification Numbers Obligation The Company’s RINs Obligation is categorized as Level 2 and is measured at fair value using the market approach based on quoted prices from an independent pricing service. See Note 7 - “ Commitments and Contingencies ” for further information on the Company’s RINs Obligation. Hierarchy of Recurring Fair Value Measurements The Company’s recurring assets and liabilities measured at fair value were as follows (in millions): March 31, 2019 December 31, 2018 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Derivative assets: Inventory financing obligation $ — $ — $ — $ — $ — $ — $ 1.5 $ 1.5 Diesel crack spread swaps — — 6.6 6.6 — — 7.4 7.4 Diesel percentage basis crack spread swaps — — 3.8 3.8 — — (6.0 ) (6.0 ) WCS crude oil basis swaps — — 11.4 11.4 — — 14.9 14.9 WCS crude oil percentage basis swaps — — 1.1 1.1 — — (6.1 ) (6.1 ) Midland crude oil basis swaps — — 5.5 5.5 — — 8.1 8.1 Total derivative assets — — 28.4 28.4 — — 19.8 19.8 Pension plan investments — — — — 0.1 — — 0.1 Total recurring assets at fair value $ — $ — $ 28.4 $ 28.4 $ 0.1 $ — $ 19.8 $ 19.9 Liabilities: Derivative liabilities: Inventory financing obligation $ — $ — $ (11.2 ) $ (11.2 ) $ — $ — $ — $ — Total derivative liabilities — — (11.2 ) (11.2 ) — — — — RINs Obligation — (14.2 ) — (14.2 ) — (15.8 ) — (15.8 ) Liability Awards (5.8 ) — — (5.8 ) (2.7 ) — — (2.7 ) Total recurring liabilities at fair value $ (5.8 ) $ (14.2 ) $ (11.2 ) $ (31.2 ) $ (2.7 ) $ (15.8 ) $ — $ (18.5 ) The table below sets forth a summary of net changes in fair value of the Company’s Level 3 financial assets and liabilities (in millions): Three Months Ended March 31, 2019 2018 Fair value at January 1, $ 19.8 $ (10.4 ) Realized (gain) loss on derivative instruments (11.7 ) 2.1 Unrealized gain (loss) on derivative instruments (2.6 ) 2.0 Settlements 11.7 (2.1 ) Fair value at March 31, $ 17.2 $ (8.4 ) Total gain (loss) included in net income (loss) attributable to changes in unrealized gain (loss) relating to financial assets and liabilities held as of March 31, 2019 $ (2.6 ) $ 2.0 All settlements from derivative instruments not designated as hedges are recorded in gain (loss) on derivative instruments in the unaudited condensed consolidated statements of operations. See Note 10 - “ Derivatives ” for further information on derivative instruments. Nonrecurring Fair Value Measurements Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. Assets and liabilities acquired in business combinations are recorded at their fair value as of the date of acquisition. The Company reviews for goodwill impairment annually on October 1 and whenever events or changes in circumstances indicate its carrying value may not be recoverable. The fair value of the reporting units is determined using the income approach. The income approach focuses on the income-producing capability of an asset, measuring the current value of the asset by calculating the present value of its future economic benefits such as cash earnings, cost savings, corporate tax structure and product offerings. Value indications are developed by discounting expected cash flows to their present value at a rate of return that incorporates the risk-free rate for the use of funds, the expected rate of inflation and risks associated with the reporting unit. These assets would generally be classified within Level 3, in the event that the Company were required to measure and record such assets at fair value within its unaudited condensed consolidated financial statements. The Company periodically evaluates the carrying value of long-lived assets to be held and used, including definite-lived intangible assets and property, plant and equipment, when events or circumstances warrant such a review. Fair value is determined primarily using anticipated cash flows assumed by a market participant discounted at a rate commensurate with the risk involved and these assets would generally be classified within Level 3, in the event that the Company was required to measure and record such assets at fair value within its unaudited condensed consolidated financial statements. The Company’s investment in FHC is a non-marketable equity security without a readily determinable fair value. The Company records this investment using a measurement alternative which measures the security at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes with a same or similar security from the same issuer. The investment in FHC is recorded at fair value only if an impairment or observable price adjustment is recognized in the current period. If an observable price adjustment or impairment is recognized, the Company would classify this asset as Level 3 within the fair value hierarchy based on the nature of the fair value inputs. Estimated Fair Value of Financial Instruments Cash and cash equivalents The carrying value of cash and cash equivalents is each considered to be representative of its fair value. Debt The estimated fair value of long-term debt at March 31, 2019 and December 31, 2018 , consists primarily of senior notes. The estimated aggregate fair value of the Company’s senior notes defined as Level 1 was based upon quoted market prices in an active market. The carrying value of borrowings, if any, under the Company’s revolving credit facility, finance lease obligations and other obligations approximate their fair values as determined by discounted cash flows and are classified as Level 3. See Note 9 - “ Long-Term Debt ” for further information on long-term debt. The Company’s carrying and estimated fair value of the Company’s financial instruments, carried at adjusted historical cost were as follows (in millions): March 31, 2019 December 31, 2018 Level Fair Value Carrying Value Fair Value Carrying Value Financial Instrument: Senior notes 1 $ 1,478.1 $ 1,538.7 $ 1,287.4 $ 1,560.7 Finance lease and other obligations 3 $ 8.2 $ 8.2 $ 47.6 $ 47.6

Segment Reporting [Abstract]
Segments and Related Information	a. Segment Reporting The Company manages its business in two operating segments, which are grouped on the basis of similar product, market and operating factors into the following reportable segments: • Specialty Products. The specialty products segment is our core business which produces a variety of lubricating oils, solvents, waxes, synthetic lubricants and other products which are sold to customers who purchase these products primarily as raw material components for basic automotive, industrial and consumer goods. Specialty products also include synthetic lubricants used in manufacturing, mining and automotive applications. • Fuel Products . The fuel products segment produces primarily gasoline, diesel, jet fuel, asphalt and other products which are primarily sold to customers located in the PADD 2 and PADD 4 areas within the U.S. The accounting policies of the reporting segments are the same as those described in the summary of significant accounting policies as disclosed in Note 2 — “Summary of Significant Accounting Policies” in Part II, Item 8 “Financial Statements and Supplementary Data” of the Company’s 2018 Annual Report, except that the disaggregated financial results for the reporting segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for the purposes of assisting internal operating decisions. The Company accounts for intersegment sales and transfers at cost plus a specified mark-up. The Company evaluates performance based upon Adjusted EBITDA (a non-GAAP financial measure). The Company defines Adjusted EBITDA for any period as EBITDA adjusted for (a) impairment; (b) unrealized gains and losses from mark to market accounting for hedging activities; (c) realized gains and losses under derivative instruments excluded from the determination of net income (loss); (d) non-cash equity-based compensation expense and other non-cash items (excluding items such as accruals of cash expenses in a future period or amortization of a prepaid cash expense) that were deducted in computing net income (loss); (e) debt refinancing fees, premiums and penalties; (f) any net loss realized in connection with an asset sale that was deducted in computing net income (loss) and (g) all extraordinary, unusual or non-recurring items of gain or loss, or revenue or expense. The Company manages its assets on a total company basis, not by segment. Therefore, management does not review any asset information by segment and, accordingly, the Company does not report asset information by segment. Reportable segment information for the three months ended March 31, 2019 and 2018 , is as follows (in millions): Three Months Ended March 31, 2019 Specialty Products Fuel Products Combined Segments Eliminations Consolidated Total Sales: External customers $ 352.2 $ 499.1 $ 851.3 $ — $ 851.3 Intersegment sales — 11.0 11.0 (11.0 ) — Total sales $ 352.2 $ 510.1 $ 862.3 $ (11.0 ) $ 851.3 Income from unconsolidated affiliates $ 3.8 $ — $ 3.8 $ — $ 3.8 Adjusted EBITDA $ 56.3 $ 41.4 $ 97.7 $ — $ 97.7 Reconciling items to net income: Depreciation and amortization 12.2 20.8 33.0 — 33.0 Gain on sale of unconsolidated affiliate (1.2 ) — (1.2 ) — (1.2 ) Unrealized loss on derivatives 2.6 Interest expense 32.3 Gain on debt extinguishment (0.4 ) Loss on impairment and disposal of fixed assets 11.7 Equity based compensation and other items 3.4 Income tax benefit (0.1 ) Net income from continuing operations $ 16.4 Three Months Ended March 31, 2018 Specialty Products Fuel Products Combined Segments Eliminations Consolidated Total Sales: External customers $ 321.8 $ 428.7 $ 750.5 $ — $ 750.5 Intersegment sales — 9.8 9.8 (9.8 ) — Total sales $ 321.8 $ 438.5 $ 760.3 $ (9.8 ) $ 750.5 Loss from unconsolidated affiliates $ (3.7 ) $ — $ (3.7 ) $ — $ (3.7 ) Adjusted EBITDA $ 37.7 $ 38.7 $ 76.4 $ — $ 76.4 Reconciling items to net loss: Depreciation and amortization 14.3 18.7 33.0 — 33.0 Unrealized gain on derivatives (2.0 ) Interest expense 45.2 Loss on debt extinguishment 0.6 Equity based compensation and other items 2.7 Income tax benefit (0.2 ) Net loss from continuing operations $ (2.9 ) b.

Leases (Notes)

Leases (Notes)	3 Months Ended

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	14. Leases The Company has various operating and finance leases primarily for the use of land, storage tanks, railcars, equipment, precious metals and office facilities that have remaining lease terms of greater than one year to 15 years, some of which include options to extend the lease for up to 35 years , and some of which include options to terminate the lease within one year. Effective January 1, 2019, the Company adopted ASU 2016-02 using a modified retrospective transition approach that applied the new standard to all leases existing at the effective date of the standard with no restatement of prior periods. Given the adoption of ASU 2016-02, the Company’s operating leases have been included in operating lease right-of-use (“ROU”) assets, current portion of operating lease liabilities and long-term portion of operating lease liabilities in the condensed consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. The Company’s finance leases are included in property, plant and equipment, current portion of long-term debt and long term debt, less current portion in the condensed consolidated balance sheets, which remains consistent with the Company’s presentation of its finance leases prior to the adoption of ASU 2016-02. The Company elected to apply the following practical expedients and policy elections provided by the standard at transition: • Package of Three - The Company has elected that it will not reassess contracts that have expired or existed at the date of adoption for (1) leases under the new definition of a lease, (2) lease classification, and (3) whether previously capitalized initial direct costs would qualify for capitalization under ASC 842. • Portfolio Approach - The Company elected to determine the discount rate used to measure lease liabilities at the portfolio level. Specifically, the Company segregated its leases into different populations based on lease term. • Discount Rate - The Company elected to apply the discount rate at transition based on the remaining lease term and lease payments rather than the original lease term and lease payments. As a majority of the Company’s leases do not provide an implicit rate, the Company used an incremental borrowing rate based on information available at the date of transition to determine the present value of lease payments. • Lease/Non-Lease Components - The Company elected to not separate non-lease components. • Definition of Minimum Rental Payments - The Company elected to include executory costs as part of the minimum lease payments for purposes of measuring the lease liability and right-of-use asset at transition. • Land Easement - The Company elected not to assess whether any land easements are, or contain, leases in accordance with ASC 842 when transitioning to the standard. Supplemental balance sheet information related to the Company’s leases for the three months ended March 31, 2019, were as follows (in millions): March 31, 2019 Assets: Classification: Operating lease assets Operating lease right-of-use assets (2) $ 134.4 Finance lease assets Property, plant and equipment, net (1) 3.9 Total leased assets $ 138.3 Liabilities: Current Operating Current portion of operating lease liabilities (2) $ 61.3 Finance Current portion of long-term debt 0.7 Non-current Operating Long-term operating lease liabilities (2) 73.6 Finance Long term debt, less current portion 2.6 Total lease liabilities $ 138.2 (1) Finance lease assets are recorded net of accumulated amortization of $6.3 million as of March 31, 2019 . (2) In the first quarter of 2019, the Company had additions to its operating lease right of use assets and operating lease liabilities of approximately $1.3 million . The components of lease expense related to the Company’s leases for the three months ended March 31, 2019 were as follows (in millions). Lease expense for lease payments is recognized on a straight-line basis over the lease term. Three Months Ended March 31, Lease Costs: Classification: 2019 Fixed operating lease cost Cost of Sales; SG&A Expenses $ 17.7 Short-term operating lease cost (1) Cost of Sales; SG&A Expenses 2.0 Variable operating lease cost (2) (3) Cost of Sales; SG&A Expenses 1.1 Finance lease cost: Amortization of right-of-use asset Cost of Sales 0.3 Interest on lease liabilities Interest expense 1.0 Total lease cost $ 22.1 (1) The Company’s leases with an initial term of 12 months or less are not recorded on the condensed consolidated balance sheet. (2) Approximately $1.0 million of the Company’s variable operating lease cost relates to its lease agreement with Phillips 66 related to the LVT unit at its Lake Charles, Louisiana refinery (“The LVT Agreement”). Pursuant to the LVT Agreement, Phillips 66 is obligated to supply a minimum supply quantity which the Company agrees to purchase through December 31, 2020. Pricing for the agreement is indexed to the prior month’s average of Platts Mid USGC 55 Grade Jet Kero price on the day of loading plus an adder. Phillips 66 invoices the Company for the estimated volume of product to be purchased by the Company based on a supplied forecast and differences between actual volumes purchased and the estimated volume of product originally billed makes up the variable component of the operating lease contract. (3) The Company’s railcar leases typically include a mileage limit the railcar can travel over the life of the lease. For any mileage incurred over this limit, the Company is obligated to pay an agreed upon dollar value for each mile that is traveled over the limit. As of March 31, 2019, the Company had estimated minimum commitments for the payment of rentals under leases which, at inception, had a noncancelable term of more than one year, as follows (in millions): Maturity of Lease Liabilities Operating Leases (1) Finance Leases (2) Total 2019 $ 52.2 $ 0.8 $ 53.0 2020 63.5 0.5 64.0 2021 12.4 0.5 12.9 2022 8.7 0.5 9.2 2023 6.0 0.5 6.5 Thereafter 6.5 1.6 8.1 Total $ 149.3 $ 4.4 $ 153.7 Less: Interest 14.4 1.1 15.5 Present value of lease liabilities $ 134.9 $ 3.3 $ 138.2 (1) As of March 31, 2019, the Company’s operating lease payments included no material options to extend lease terms that are reasonably certain of being exercised. The Company has $3.7 million of legally binding minimum lease payments for leases signed but not yet commenced as of March 31, 2019. (2) As of March 31, 2019, the Company’s finance lease payments included no material options to extend lease terms that are reasonably certain of being exercised. In addition, the Company has no legally binding minimum lease payments for leases that have been signed but not yet commenced as of March 31, 2019. Weighted-Average Lease Term and Discount Rate The weighted-average remaining lease term and weighted-average discount rate for the Company’s operating and finance leases as of March 31, 2019 were as follows: Three Months Ended March 31, Lease Term and Discount Rate: 2019 Weighted-average remaining lease term (years) Operating leases 2.8 Finance leases 3.9 Weighted-average discount rate Operating leases 7.3 % Finance leases 6.4 %

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Fair Value Measurement [Policy Text Block]	The Company’s investment in FHC is a non-marketable equity security without a readily determinable fair value. The Company records this investment using a measurement alternative which measures the security at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes with a same or similar security from the same issuer. The investment in FHC is recorded at fair value only if an impairment or observable price adjustment is recognized in the current period. If an observable price adjustment or impairment is recognized, the Company would classify this asset as Level 3 within the fair value hierarchy based on the nature of the fair value inputs.
Inventory Financing [Policy Text Block]	While title to certain inventories will reside with Macquarie, the Supply and Offtake Agreements are accounted for by the Company similar to a product financing arrangement; therefore, the inventories sold to Macquarie will continue to be included in the Company’s condensed consolidated balance sheets until processed and sold to a third party. Each reporting period, the Company will record liabilities in an amount equal to the amount the Company expects to pay to repurchase the inventory held by Macquarie based on market prices at the termination date included in obligations under inventory financing agreements in the condensed consolidated balance sheets. The Company has determined that the redemption feature on the initially recognized liabilities related to the Supply and Offtake Agreements is an embedded derivative indexed to commodity prices. As such, the Company has accounted for these embedded derivatives at fair value with changes in the fair value, if any, recorded in gain (loss) on derivative instruments in the Company’s unaudited condensed consolidated statements of operations. For more information on the valuation of the associated derivatives, see Note 10 - “ Derivatives ” and Note 11 - “ Fair Value Measurements .” The embedded derivatives will be recorded in obligations under inventory financing agreements on the condensed consolidated balance sheets. The cash flow impact of the embedded derivatives will be classified as a change in inventory financing activity in the financing activities section in the unaudited condensed consolidated statements of cash flows.
Basis of Accounting	The unaudited condensed consolidated financial statements of the Company as of March 31, 2019 and for the three months ended March 31, 2019 and 2018 , included herein have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the following disclosures are adequate to make the information presented not misleading. The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These unaudited condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations for the interim periods presented. All adjustments are of a normal nature, unless otherwise disclosed. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s 2018 Annual Report.
RINS Obligation	The Company’s Renewable Identification Numbers (“RINs”) obligation (“RINs Obligation”) represents a liability for the purchase of RINs to satisfy the EPA requirement to blend biofuels into the fuel products it produces pursuant to the EPA’s RFS. RINs are assigned to biofuels produced in the U.S. as required by the EPA. The EPA sets annual quotas for the percentage of biofuels that must be blended into transportation fuels consumed in the U.S. and, as a producer of motor fuels from petroleum, the Company is required to blend biofuels into the fuel products it produces at a rate that will meet the EPA’s annual quota. To the extent the Company is unable to blend biofuels at that rate, it must purchase RINs in the open market to satisfy the annual requirement. The Company’s RINs Obligation is based on the amount of RINs it must purchase and the price of those RINs as of the balance sheet date. The Company uses the inventory model to account for RINs, measuring acquired RINs at weighted-average cost. The cost of RINs used each period is charged to cost of sales with cash inflows and outflows recorded in the operating cash flow section of the unaudited condensed consolidated statements of cash flows. The liability is calculated by multiplying the RINs shortage (based on actual results) by the period end RIN spot price. The Company recognizes an asset at the end of each reporting period in which it has generated RINs in excess of its RINs Obligation. The asset is initially recorded at cost at the time the Company acquires them and are subsequently revalued at the lower of cost or market as of the last day of each accounting period and the resulting adjustments are reflected in costs of sales for the period in the unaudited condensed consolidated statements of operations. The value of RINs in excess of the RINs Obligation, if any, would be reflected in other current assets on the condensed consolidated balance sheets. RINs generated in excess of the Company’s current RINs Obligation may be sold or held to offset future RINs Obligations. Any such sales of excess RINs are recorded in cost of sales in the unaudited condensed consolidated statements of operations. The assets and liabilities associated with the Company’s RINs Obligation are considered recurring fair value measurements.
New Accounting Pronouncements	Adopted Accounting Pronouncements On January 1, 2019, the Company adopted ASU No. 2016-02 , Leases (Topic 842) (“ASU 2016-02”) and all the related amendments to its lease contracts using the modified retrospective method. The effective date was used as the Company’s date of initial application with no restatement of prior periods. As such, prior periods continue to be reported under the accounting standards in effect for those periods. See Note 14 - “ Leases ” for further information. On January 1, 2019, the Company adopted ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which improves the financial reporting of hedging relationships to better align risk management activities in financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. Given the Company’s current risk management strategy of not designating any of its derivative positions as hedges, the adoption of this guidance had no effect on our consolidated financial statements. If, in the future, the Company decides to modify its hedging strategies, this new accounting guidance would become applicable and will be applied at that time. On January 1, 2019, the Company adopted ASU No. 2018-07, Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). This update simplifies the guidance related to nonemployee share-based payments by superseding ASC 505-50 and expanding the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both nonemployees and employees. Prior to the issuance of this standard update, nonemployee share-based payments were subject to ASC 505-50 requirements while employee shared-based payments were subject to ASC 718 requirements. ASU 2018-07 is effective for fiscal years (including interim periods) beginning after December 15, 2018, with early adoption permitted. The adoption of ASU 2018-07 had no impact on the Company’s consolidated financial statements.
Revenue from Contract with Customer [Policy Text Block]	The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. For each contract, the Company considers the promise to transfer products, each of which are distinct, to be the identified performance obligations. In determining the transaction price, the Company evaluates whether the price is subject to variable consideration such as product returns, rebates or other discounts to determine the net consideration to which the Company expects to be entitled. The Company transfers control and recognizes revenue upon shipment to the customer or, in certain cases, upon receipt by the customer in accordance with contractual terms. Revenue is recognized when obligations under the terms of a contract with a customer are satisfied; recognition generally occurs with the transfer of control at a point in time. The contract with the customer states the final terms of the sale, including the description, quantity and price of each product or service purchased. For fuel products, payment is typically due in full between 2 to 30 days of delivery or the start of the contract term, such that payment is typically collected 2 to 30 days subsequent to the satisfaction of performance obligations. For specialty products, payment is typically due in full between 30 to 90 days of delivery or the start of the contract term, such that payment is typically collected 30 to 90 days subsequent to the satisfaction of performance obligations. In the normal course of business, the Company does not accept product returns unless the item is defective as manufactured. The expected costs associated with a product assurance warranty continues to be recognized as expense when products are sold. The Company does not offer promised services that could be considered warranties that are sold separately or provide a service in addition to assurance that the related product complies with agreed upon specifications. The Company establishes provisions based on the methods described in ASC 606 for estimated returns and warranties as variable consideration when determining the transaction price. Shipping and handling costs are deemed to be fulfillment activities rather than a separate distinct performance obligation Revenues are recognized when control of the promised goods are transferred to the customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods promised within each contract and determines the performance obligations and assesses whether each promised good is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. The Company may incur incremental costs to obtain a sales contract, which under ASC 606 should be capitalized and amortized over the life of the contract. The Company has elected to apply the practical expedient in ASC 340-40-50-5 allowing the Company to expense these costs since the contracts are short-term in nature with a contract term of one year or less. the Company collects and remits sales taxes associated with certain sales of its products to non-exempt customers. The Company excludes excise taxes and sales taxes that are collected from customers from the transaction price in its contracts with customers. Accordingly, revenue from contracts with customers is net of sales-based taxes that are collected from customers and remitted to taxing authorities. Under product sales contracts, the Company invoices customers for performance obligations that have been satisfied, at which point payment is unconditional. Accordingly, a product sales contract does not give rise to contract assets or liabilities under ASC 606.
Inventories	Under the LIFO inventory method, the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest acquisition costs. In addition, the use of the LIFO inventory method may result in increases or decreases to cost of sales in years that inventory volumes decline as the result of charging cost of sales with LIFO inventory costs generated in prior periods. In periods of rapidly declining prices, LIFO inventories may have to be written down to market value due to the higher costs assigned to LIFO layers in prior periods. The cost of inventory is recorded using the last-in, first-out (“LIFO”) method. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs and are subject to the final year-end LIFO inventory valuation. In certain circumstances, the Company may decide not to replenish inventory for certain products or product lines during an interim period, in which case, the Company may record interim LIFO adjustments during that period. During the three months ended March 31, 2019 , the Company recorded increases (exclusive of lower of cost or market (“LCM”) adjustments) of $0.9 million , in cost of sales in the unaudited condensed consolidated statements of operations due to the permanent liquidation of inventory layers. No such activity occurred in the three months ended March 31, 2018 . Costs include crude oil and other feedstocks, labor, processing costs and refining overhead costs. Inventories are valued at the lower of cost or market value.
Derivatives	Collateral received from counterparties is reported in other current liabilities, and collateral held by counterparties is reported in prepaid expenses and other current assets on the Company’s condensed consolidated balance sheets and is not netted against derivative assets or liabilities. Any outstanding collateral is released to the Company upon settlement of the related derivative instrument liability. For derivative instruments not designated as hedges, the change in fair value of the asset or liability for the period is recorded to gain (loss) on derivative instruments in the unaudited condensed consolidated statements of operations. Upon the settlement of a derivative not designated as a hedge, the gain or loss at settlement is recorded to gain (loss) on derivative instruments in the unaudited condensed consolidated statements of operations. The Company has entered into gasoline swaps, diesel swaps and certain crude oil basis swaps that do not qualify as cash flow hedges for accounting purposes as they were not entered into simultaneously with a corresponding NYMEX WTI derivative contract. However, these instruments provide economic hedges of the Company’s crude oil purchases and gasoline and diesel sales. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings. In the event of default, the Company would potentially be subject to losses on derivative instruments with mark-to-market gains. The Company requires collateral from its counterparties when the fair value of the derivatives exceeds agreed-upon thresholds in its master derivative contracts with these counterparties. The Company is exposed to price risks due to fluctuations in the price of crude oil, refined products (primarily in the Company’s fuel products segment), natural gas and precious metals. The Company uses various strategies to reduce its exposure to commodity price risk. The strategies to reduce the Company’s risk utilize both physical forward contracts and financially settled derivative instruments, such as swaps, collars, options and futures, to attempt to reduce the Company’s exposure with respect to: • crude oil purchases and sales; • fuel product sales and purchases; • natural gas purchases; • precious metals purchases; and • fluctuations in the value of crude oil between geographic regions and between the different types of crude oil such as New York Mercantile Exchange West Texas Intermediate (“NYMEX WTI”), Light Louisiana Sweet, Western Canadian Select (“WCS”), WTI Midland, Mixed Sweet Blend and ICE Brent. The Company manages its exposure to commodity markets, credit, volumetric and liquidity risks to manage its costs and volatility of cash flows as conditions warrant or opportunities become available. These risks may be managed in a variety of ways that may include the use of derivative instruments. Derivative instruments may be used for the purpose of mitigating risks associated with an asset, liability and anticipated future transactions and the changes in fair value of the Company’s derivative instruments will affect its earnings and cash flows; however, such changes should be offset by price or rate changes related to the underlying commodity or financial transaction that is part of the risk management strategy. The Company does not speculate with derivative instruments or other contractual arrangements that are not associated with its business objectives. Speculation is defined as increasing the Company’s natural position above the maximum position of its physical assets or trading in commodities, currencies or other risk bearing assets that are not associated with the Company’s business activities and objectives. The Company’s positions are monitored routinely by a risk management committee to ensure compliance with its stated risk management policy and documented risk management strategies. All strategies are reviewed on an ongoing basis by the Company’s risk management committee, which will add, remove or revise strategies in anticipation of changes in market conditions and/or its risk profiles. Such changes in strategies are to position the Company in relation to its risk exposures in an attempt to capture market opportunities as they arise. The Company is obligated to repurchase crude oil and refined products from Macquarie at the termination of the Supply and Offtake Agreements in certain scenarios. The Company has determined that the redemption feature on the initially recognized liability related to the Supply and Offtake Agreements is an embedded derivative indexed to commodity prices. As such, the Company has accounted for these embedded derivatives at fair value with changes in the fair value, if any, recorded in gain (loss) on derivative instruments in the Company’s unaudited condensed consolidated statement of operations. The Company recognizes all derivative instruments at their fair values (see Note 11 - “ Fair Value Measurements ”) as either current assets or current liabilities in the condensed consolidated balance sheets. Fair value includes any premiums paid or received and unrealized gains and losses. Fair value does not include any amounts receivable from or payable to counterparties, or collateral provided to counterparties. Derivative asset and liability amounts with the same counterparty are netted against each other for financial reporting purposes in accordance with the provisions of our master netting arrangements. The cash flow impact of the Company’s derivative activities is classified primarily as a change in derivative activity in the operating activities section in the unaudited condensed consolidated statements of cash flows. Certain of the Company’s outstanding derivative instruments are subject to credit support agreements with the applicable counterparties which contain provisions setting certain credit thresholds above which the Company may be required to post agreed-upon collateral, such as cash or letters of credit, with the counterparty to the extent that the Company’s mark-to-market net liability, if any, on all outstanding derivatives exceeds the credit threshold amount per such credit support agreement. The majority of the credit support agreements covering the Company’s outstanding derivative instruments also contain a general provision stating that if the Company experiences a material adverse change in its business, in the reasonable discretion of the counterparty, the Company’s credit threshold could be lowered by such counterparty.
Fair Value Measurement	The carrying value of cash and cash equivalents is each considered to be representative of its fair value. Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. Assets and liabilities acquired in business combinations are recorded at their fair value as of the date of acquisition. The Company reviews for goodwill impairment annually on October 1 and whenever events or changes in circumstances indicate its carrying value may not be recoverable. The fair value of the reporting units is determined using the income approach. The income approach focuses on the income-producing capability of an asset, measuring the current value of the asset by calculating the present value of its future economic benefits such as cash earnings, cost savings, corporate tax structure and product offerings. Value indications are developed by discounting expected cash flows to their present value at a rate of return that incorporates the risk-free rate for the use of funds, the expected rate of inflation and risks associated with the reporting unit. These assets would generally be classified within Level 3, in the event that the Company were required to measure and record such assets at fair value within its unaudited condensed consolidated financial statements. The Company periodically evaluates the carrying value of long-lived assets to be held and used, including definite-lived intangible assets and property, plant and equipment, when events or circumstances warrant such a review. Fair value is determined primarily using anticipated cash flows assumed by a market participant discounted at a rate commensurate with the risk involved and these assets would generally be classified within Level 3, in the event that the Company was required to measure and record such assets at fair value within its unaudited condensed consolidated financial statements. Observable inputs utilized to estimate the fair values of the Company’s derivative instruments were based primarily on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Based on the use of various unobservable inputs, principally non-performance risk, creditworthiness of the counterparties and unobservable inputs in the forward rate, the Company has categorized these derivative instruments as Level 3. Significant increases (decreases) in any of those unobservable inputs in isolation would result in a significantly lower (higher) fair value measurement. The Company believes it has obtained the most accurate information available for the types of derivative instruments it holds. To estimate the fair values of the Company’s commodity derivative instruments, the Company uses the forward rate, the strike price, contractual notional amounts, the risk free rate of return and contract maturity. Various analytical tests are performed to validate the counterparty data. The fair values of the Company’s derivative instruments are adjusted for nonperformance risk and creditworthiness of the counterparty through the Company’s credit valuation adjustment (“CVA”). The CVA is calculated at the counterparty level utilizing the fair value exposure at each payment date and applying a weighted probability of the appropriate survival and marginal default percentages. The Company uses the counterparty’s marginal default rate and the Company’s survival rate when the Company is in a net asset position at the payment date and uses the Company’s marginal default rate and the counterparty’s survival rate when the Company is in a net liability position at the payment date. The estimated aggregate fair value of the Company’s senior notes defined as Level 1 was based upon quoted market prices in an active market. The carrying value of borrowings, if any, under the Company’s revolving credit facility, finance lease obligations and other obligations approximate their fair values as determined by discounted cash flows and are classified as Level 3. Unit based compensation liability awards are awards that are expected to be settled in cash on their vesting dates, rather than in equity units (“Liability Awards”). The Liability Awards are categorized as Level 1 because the fair value of the Liability Awards is based on the Company’s quoted closing unit price as of each balance sheet date. Pension assets are reported at fair value in the accompanying unaudited condensed consolidated financial statements. At March 31, 2019 , the Company’s investments associated with its pension plan primarily consisted of mutual funds. The mutual funds are valued at the net asset value of shares in each fund held by the Pension Plan at quarter end as provided by the respective investment sponsors or investment advisers. Plan investments can be redeemed within a short time frame (approximately 10 business days), if requested. All settlements from derivative instruments not designated as hedges are recorded in gain (loss) on derivative instruments in the unaudited condensed consolidated statements of operations. The Company’s RINs Obligation is categorized as Level 2 and is measured at fair value using the market approach based on quoted prices from an independent pricing service. The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. Observable inputs are from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. These tiers include the following: • Level 1 — inputs include observable unadjusted quoted prices in active markets for identical assets or liabilities • Level 2 — inputs include other than quoted prices in active markets that are either directly or indirectly observable • Level 3 — inputs include unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions In determining fair value, the Company uses various valuation techniques and prioritizes the use of observable inputs. The availability of observable inputs varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded and other characteristics particular to the instrument. For many financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants and the valuation does not require significant management judgment. For other financial instruments, pricing inputs are less observable in the marketplace and may require management judgment. Derivative instruments are reported in the accompanying unaudited condensed consolidated financial statements at fair value. The Company’s derivative instruments consist of over-the-counter contracts, which are not traded on a public exchange.
Segment Reporting	The Company offers specialty products primarily in categories consisting of lubricating oils, solvents, waxes, synthetic lubricants and other products. Fuel products categories primarily consist of gasoline, diesel, jet fuel, asphalt and other products. The Company manages its business in two operating segments, which are grouped on the basis of similar product, market and operating factors into the following reportable segments: • Specialty Products. The specialty products segment is our core business which produces a variety of lubricating oils, solvents, waxes, synthetic lubricants and other products which are sold to customers who purchase these products primarily as raw material components for basic automotive, industrial and consumer goods. Specialty products also include synthetic lubricants used in manufacturing, mining and automotive applications. • Fuel Products . The fuel products segment produces primarily gasoline, diesel, jet fuel, asphalt and other products which are primarily sold to customers located in the PADD 2 and PADD 4 areas within the U.S. The accounting policies of the reporting segments are the same as those described in the summary of significant accounting policies as disclosed in Note 2 — “Summary of Significant Accounting Policies” in Part II, Item 8 “Financial Statements and Supplementary Data” of the Company’s 2018 Annual Report, except that the disaggregated financial results for the reporting segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for the purposes of assisting internal operating decisions. The Company accounts for intersegment sales and transfers at cost plus a specified mark-up. The Company evaluates performance based upon Adjusted EBITDA (a non-GAAP financial measure). The Company defines Adjusted EBITDA for any period as EBITDA adjusted for (a) impairment; (b) unrealized gains and losses from mark to market accounting for hedging activities; (c) realized gains and losses under derivative instruments excluded from the determination of net income (loss); (d) non-cash equity-based compensation expense and other non-cash items (excluding items such as accruals of cash expenses in a future period or amortization of a prepaid cash expense) that were deducted in computing net income (loss); (e) debt refinancing fees, premiums and penalties; (f) any net loss realized in connection with an asset sale that was deducted in computing net income (loss) and (g) all extraordinary, unusual or non-recurring items of gain or loss, or revenue or expense. The Company manages its assets on a total company basis, not by segment. Therefore, management does not review any asset information by segment and, accordingly, the Company does not report asset information by segment.

Leases [Abstract]
Lease, Implementation Method [Policy Text Block]	Effective January 1, 2019, the Company adopted ASU 2016-02 using a modified retrospective transition approach that applied the new standard to all leases existing at the effective date of the standard with no restatement of prior periods.
Lease, Package of Three, Practical Expedients [Policy Text Block]	Package of Three - The Company has elected that it will not reassess contracts that have expired or existed at the date of adoption for (1) leases under the new definition of a lease, (2) lease classification, and (3) whether previously capitalized initial direct costs would qualify for capitalization under ASC 842.
Lease, Practical Expedients, Package [true false]	true
Leases - Portfolio Approach [Policy Text Block]	Portfolio Approach - The Company elected to determine the discount rate used to measure lease liabilities at the portfolio level. Specifically, the Company segregated its leases into different populations based on lease term.
Short-term Leases [Policy Text Block]	The Company’s leases with an initial term of 12 months or less are not recorded on the condensed consolidated balance sheet.
Lease, Discount Rate Election [Policy Text Block]	Discount Rate - The Company elected to apply the discount rate at transition based on the remaining lease term and lease payments rather than the original lease term and lease payments. As a majority of the Company’s leases do not provide an implicit rate, the Company used an incremental borrowing rate based on information available at the date of transition to determine the present value of lease payments.
Separation of Lease and Nonlease Components [Policy Text Block]	Lease/Non-Lease Components - The Company elected to not separate non-lease components.
Definition of Minimum Rental Payments [Policy Text Block]	Definition of Minimum Rental Payments - The Company elected to include executory costs as part of the minimum lease payments for purposes of measuring the lease liability and right-of-use asset at transition.
Leases, Land Easement Election [Policy Text Block]	Land Easement - The Company elected not to assess whether any land easements are, or contain, leases in accordance with ASC 842 when transitioning to the standard.
