Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Business	(1) Organization and Nature of Business CVR Refining, LP and subsidiaries ("CVR Refining" or the "Partnership") is a refiner that does not have crude oil exploration or production operations (an "independent petroleum refiner") and is a marketer of high value transportation fuels. The Partnership owns a complex full coking medium-sour crude oil refinery in Coffeyville, Kansas and a complex crude oil refinery in Wynnewood, Oklahoma. As of June 30, 2018 , Coffeyville Resources, LLC ("CRLLC"), a wholly-owned subsidiary of CVR Energy, Inc. ("CVR Energy"), owned 100% of the Partnership's noneconomic general partner interest and approximately 66% of the Partnership's outstanding limited partner interests. As of June 30, 2018 , Icahn Enterprises L.P. ("IEP") and its affiliates owned approximately 82% of CVR Energy's outstanding shares. CVR Refining's common units, which are listed on the New York Stock Exchange ("NYSE"), began trading on January 17, 2013 under the symbol "CVRR." On June 18, 2018, CVR Energy commenced an offer to exchange up to 37,154,236 common units of CVR Refining for shares of CVR Energy common stock at an exchange ratio of one common unit for 0.6335 shares of CVR Energy common stock. The offer and withdrawal rights will expire on July 27, 2018 at 5:00 pm, unless the offer is extended by CVR Energy. Management and Operations The Partnership is party to a services agreement pursuant to which the Partnership and its general partner obtain certain management and other services from CVR Energy. The Partnership's general partner manages the Partnership's activities subject to the terms and conditions specified in CVR Refining's partnership agreement. The operations of the general partner, in its capacity as general partner, are managed by its board of directors. Actions by the general partner that are made in its individual capacity are made by CVR Refining Holdings, LLC ("CVR Refining Holdings"), a subsidiary of CRLLC, as the sole member of the Partnership's general partner and not by the board of directors of the general partner. The members of the board of directors of the Partnership's general partner are not elected by the Partnership's unitholders and are not subject to re-election on a regular basis. The officers of the general partner manage the day-to-day affairs of the business. The Partnership also has agreements with a subsidiary of CVR Partners, LP ("CVR Partners"), an indirect subsidiary of CVR Energy, under which the Partnership sells petroleum coke and hydrogen to CVR Partners Coffeyville Facility. Additionally, the two parties provide feedstock and other services to one another at the Coffeyville Facility. See Note 14 ("Related Party Transactions") for further discussion.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	(2) Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and in accordance with the rules and regulations of the Securities and Exchange Commission (the "SEC"). These condensed consolidated financial statements should be read in conjunction with the December 31, 2017 audited consolidated financial statements and notes thereto included in CVR Refining's Annual Report on Form 10-K for the year ended December 31, 2017 , which was filed with the SEC on February 26, 2018 (the " 2017 Form 10-K"). The condensed consolidated financial statements include certain selling, general and administrative expenses (exclusive of depreciation and amortization) and direct operating expenses (exclusive of depreciation and amortization) that CVR Energy and its affiliates incurred on behalf of and charged to the Partnership. These related party transactions are governed by the services agreement. See Note 14 ("Related Party Transactions") for additional discussion of the services agreement and billing of certain costs. In the opinion of the Partnership's management, the accompanying condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that are necessary to fairly present the financial position of the Partnership as of June 30, 2018 and December 31, 2017 , the results of operations of the Partnership for the three and six month periods ended June 30, 2018 and 2017 and the cash flows of the Partnership for the six month periods ended June 30, 2018 and 2017 . Certain information has been reclassified to present historical information in a manner consistent with current presentation. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Results of operations and cash flows for the interim periods presented are not necessarily indicative of the results that will be realized for the year ending December 31, 2018 or any other interim or annual period.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	(3) Recent Accounting Pronouncements Adoption of New Revenue Standard On January 1, 2018, the Partnership adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 606, "Revenue from Contracts with Customers" (“ASC 606”) using the modified retrospective method applied to contracts which were not completed as of January 1, 2018. The standard was applied prospectively and the comparative information for 2017 has not been restated and continues to be reported under the accounting standards in effect for the prior period. The Partnership did not identify any material differences in its existing revenue recognition methods that require modification under the new standard and, as such, a cumulative effect adjustment of applying the standard using the modified retrospective method was not recorded. Impact on Financial Statements The Partnership identified a presentation change associated with a fee collected from certain customers that were previously recorded as a reduction to cost of materials and other. The particular fee, the Oil Spill Liability Tax, relates to taxes imposed on refineries as part of the crude oil procurement process, and is charged to certain of the Partnership’s customers on product sales and is required under the new standard to be included in the transaction price. The impact of the change in presentation was an increase of $1 million to net sales and cost of materials and other for the three and six months ended June 30, 2018 . New Accounting Standards Issued But Not Yet Implemented In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, “Leases” (“ASU 2016-02”) creating a new topic, FASB ASC Topic 842, "Leases," which supersedes lease requirements in FASB ASC Topic 840, "Leases." The new standard revises accounting for operating leases by a lessee, among other changes, and requires a lessee to recognize a liability related to future lease payments and an asset representing its right to use the underlying asset for the lease term in the balance sheet. Quantitative and qualitative disclosures, including disclosures regarding significant judgments made by management, will be required. The standard is effective for the first interim and annual periods beginning after December 15, 2018, with early adoption permitted. At adoption, ASU 2016-02 will be applied using the modified retrospective application method and allows for certain practical expedients. The Partnership has begun its assessment and implementation plan for its planned adoption effective January 1, 2019. The Partnership expects the impact of the new lease standard to be material with respect to its balance sheet and further expect impacts to disclosures and changes in internal lease accounting processes.

Revenue from Contract with Customer [Abstract]
Revenue	(4) Revenue The following table presents the Partnership’s revenue disaggregated by major product. Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 (in millions) Major Product Gasoline $ 896 $ 1,607 Distillates (a) 832 1,484 Freight revenue 6 11 Other (b) 89 177 Revenue from product sales 1,823 3,279 Other revenue (c) 1 3 Total revenue $ 1,824 $ 3,282 (a) Distillates consist primarily of diesel fuel, kerosene and jet fuel. (b) Other product sales primarily include crude oil, feedstocks and asphalt sales. Feedstocks are petroleum products, such as crude oil and natural gas liquids, that are processed and blended into refined products, such as gasoline, diesel fuel and jet fuel, during the refining process. (c) Other revenue consists primarily of Cushing, OK storage tank lease revenue. The Partnership’s revenue from product sales is recorded upon delivery of the products to customers, which is the point at which title is transferred and the customer has assumed the risk of loss. This generally takes place as product passes into the pipeline, as a product transfer order occurs within a pipeline system, or as product enters equipment or locations supplied or designated by the customer. The Partnership has elected to apply the sales tax practical expedient, whereby qualifying excise and other taxes collected from customers and remitted to governmental authorities are not included in reported revenues. Many of the Partnership’s contracts have index-based pricing which is considered variable consideration that should be estimated in determining the transaction price. The Partnership determined that it does not need to estimate the variable consideration because the uncertainty related to the consideration is resolved on the pricing date or the date when the product is delivered. The Partnership may incur broker commissions or transportation costs prior to product transfer on some of its sales. The Partnership has elected to apply the practical expedient allowing it to expense the broker costs since the contract durations are less than a year in length. Transportation costs are accounted for as fulfillment costs and are expensed as incurred since they do not meet the requirement for capitalization. The Partnership’s contracts with its customers state the terms of the sale, including the description, quantity, and price of each product sold. Depending on the product sold, payment from customers is generally due in full within 2 to 32 days of product delivery or invoice date. The Partnership’s contracts with customers commonly include a provision which states that the Partnership will accept customer returns of off-spec product, refund the customer (or provide on-spec product), and pay for damages to any customer equipment which resulted from the off-spec product. Typically, if the customer is not satisfied with the product, the price is adjusted downward instead of the product being returned or exchanged. The Partnership has determined that product returns or refunds are very rare and will account for them as they occur. The Partnership generally provides no warranty other than the implicit promise that goods delivered are free of liens and encumbrances and meet the agreed upon specification. Freight revenue recognized by the Partnership is primarily tariff and line loss charges that are rebilled to customers to reimburse the Partnership for expenses incurred from a pipeline operator. An offsetting expense is included in cost of materials and other. Transaction price allocated to remaining performance obligations As of June 30, 2018, approximately $41 million of revenue from remaining performance obligations is expected to be recognized from a contract with an initial duration of greater than one year. The Partnership will recognize revenue ratably each month through 2036 as the take-or-pay obligations under the Hydrogen Purchase and Sale Agreement are satisfied or expire. The Partnership has elected an optional exemption to not disclose the amount of transaction price allocated to remaining performance obligations for contracts with an original expected duration of less than one year. The Partnership does not disclose variable consideration related to index-based or market-based pricing as it qualifies for the variable consideration allocation exception under the new revenue standard. The variable consideration relates specifically to the Partnership’s efforts to transfer each unit of product to the customer in which the pricing is directly related to the period to which the sale occurs.

Partners' Capital and Partnership Distributions	(9) Partners' Capital and Partnership Distributions The Partnership had two types of partnership interests outstanding at June 30, 2018 , common units and general partner interest, which is not entitled to any distributions, and which is held by the general partner. At June 30, 2018 , the Partnership had a total of 147,600,000 common units issued and outstanding, of which 97,315,764 common units were owned by CVR Refining Holdings, representing approximately 66% of the total Partnership common units outstanding. Distributions The board of directors of the Partnership's general partner has adopted a policy for the Partnership to distribute all available cash generated on a quarterly basis. Cash distributions will be made to the common unitholders of record on the applicable record date, generally within 60 days after the end of each quarter. Available cash for distribution for each quarter will be determined by the board of directors of the general partner following the end of such quarter. The following is a summary of cash distributions paid to the Partnership's unitholders during 2018 for the respective quarters to which the distributions relate: December 31, 2017 March 31, 2018 Total Cash Distributions Paid in 2018 (in millions, except per unit data) Amount paid to CVR Refining Holdings, LLC and affiliates $ 47 $ 52 $ 99 Amounts paid to non-affiliates 20 23 43 Total amount paid $ 67 $ 75 $ 142 Per common unit $ 0.45 $ 0.51 $ 0.96 Common units outstanding 147.6 147.6 On July 25, 2018 , the board of directors of the Partnership's general partner declared a cash distribution for the second quarter of 2018 to the Partnership's unitholders of $0.66 per common unit, or $97 million in aggregate.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	(11) Commitments and Contingencies There have been no material changes in our commitments and contingencies disclosed in our 2017 Form 10-K. In the ordinary course of business, we may become party to lawsuits, administrative proceedings and governmental investigations, including environmental, regulatory and other matters. The outcome of these matters cannot always be predicted accurately, but we accrue liabilities for these matters if we have determined that it is probable a loss has been incurred and the loss can be reasonably estimated. While it is not possible to predict the outcome of such proceedings, if one or more of them were decided against us, we believe there would be no material impact on our consolidated financial statements. Crude Oil Supply Agreement On August 31, 2012, Coffeyville Resource Refining & Marketing, LLC ("CRRM") and Vitol Inc. ("Vitol") entered into an Amended and Restated Crude Oil Supply Agreement (as amended, the "Vitol Agreement"). Under the Vitol Agreement, Vitol supplies the petroleum business with crude oil and intermediation logistics, which helps to reduce the Partnership's inventory position and mitigate crude oil pricing risk. The Vitol Agreement will automatically renew for successive one -year terms (each such term, a "Renewal Term") unless either party provides the other with notice of nonrenewal at least 180 days prior to expiration of any Renewal Term. The Vitol Agreement currently extends through December 31, 2019. Renewable Fuel Standards CVR Refining is subject to the Renewable Fuel Standard ("RFS") of the Environmental Protection Agency ("EPA"), which requires refiners to either blend "renewable fuels" in with their transportation fuels or purchase renewable fuel credits, known as renewable identification numbers ("RINs"), in lieu of blending. Due to mandates in the RFS requiring increasing volumes of renewable fuels to replace petroleum products in the U.S. transportation fuel market, there may be a decrease in demand for petroleum products. CVR Refining is not able to blend the substantial majority of its transportation fuels and has to purchase RINs on the open market, as well as waiver credits for cellulosic biofuels from the EPA, in order to comply with the RFS. The price of RINs has been extremely volatile over the last year. The cost of RINs is dependent upon a variety of factors, which include the availability of RINs for purchase, the price at which RINs can be purchased, transportation fuel production levels, the mix of CVR Refining's petroleum products, as well as the fuel blending performed at our refineries and downstream terminals, all of which can vary significantly from period to period. The net cost of RINs for the three months ended June 30, 2018 and 2017 was $50 million and $106 million , respectively. The net cost of RINs for the six months ended June 30, 2018 and 2017 was $27 million and $99 million , respectively. The net cost of RINs is included in cost of materials and other in the Condensed Consolidated Statements of Operations. RINs expense includes the purchased cost of RINs, the impact of recognizing the Partnership’s uncommitted biofuel blending obligation at fair value based on market prices at each reporting date and is reduced by the valuation change of RINs purchases in excess of the Partnership's RFS obligation as of the reporting date. As of June 30, 2018 and December 31, 2017 , CVR Refining's biofuel blending obligation was approximately $16 million and $28 million , respectively, which is recorded in accrued expenses and other current liabilities in the Condensed Consolidated Balance Sheets. The Partnership included a RINs asset within prepaid and other current assets in the Condensed Consolidated Balance Sheet of $14 million , representing excess RINs primarily due to a reduction in its RFS obligation during the first quarter of 2018. Litigation The U.S. Attorney's office for the Southern District of New York contacted CVR Energy in September 2017 seeking production of information pertaining to CVR Refining's, CVR Energy's and Mr. Carl C. Icahn's activities relating to the Renewable Fuel Standard ("RFS") and Mr. Icahn's role as an advisor to the President. CVR Refining is cooperating with the request and is providing information in response to the subpoena. The U.S. Attorney's office has not made any claims or allegations against CVR Refining or Mr. Icahn. CVR Refining maintains a strong compliance program and, while no assurances can be made, CVR Refining does not believe this inquiry will have a material impact on its business, financial condition, results of operations or cash flows.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(12) Fair Value Measurements In accordance with ASC Topic 820 — Fair Value Measurements and Disclosures ("ASC 820"), the Partnership utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities or a group of assets or liabilities, such as a business. ASC 820 utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: • Level 1 — Quoted prices in active markets for identical assets or liabilities • Level 2 — Other significant observable inputs (including quoted prices in active markets for similar assets or liabilities) • Level 3 — Significant unobservable inputs (including CVR Refining's own assumptions in determining the fair value) The following tables set forth the assets and liabilities measured at fair value on a recurring basis, by input level, as of June 30, 2018 and December 31, 2017 : June 30, 2018 Location and Description Level 1 Level 2 Level 3 Total (in millions) Other current assets (commodity derivatives) $ — $ 1 $ — $ 1 Total Assets $ — $ 1 $ — $ 1 Other current liabilities (commodity derivatives) — (27 ) — (27 ) Other current liabilities (biofuel blending obligation) — (11 ) — (11 ) Total Liabilities $ — $ (38 ) $ — $ (38 ) December 31, 2017 Location and Description Level 1 Level 2 Level 3 Total (in millions) Other current liabilities (commodity derivatives) $ — $ (64 ) $ — $ (64 ) Other current liabilities (biofuel blending obligation) — (1 ) — (1 ) Total Liabilities $ — $ (65 ) $ — $ (65 ) As of June 30, 2018 and December 31, 2017 , the only financial assets and liabilities that are measured at fair value on a recurring basis are CVR Refining's derivative instruments and uncommitted biofuel blending obligation. Additionally, the fair value of the debt issuances is disclosed in Note 8 ("Long-Term Debt") . The commodity derivative contracts and the uncommitted biofuel blending obligation, which use fair value measurements and are valued using broker quoted market prices of similar instruments, are considered Level 2 inputs. CVR Refining had no transfers of assets or liabilities between any of the above levels during the six months ended June 30, 2018 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	(13) Derivative Financial Instruments CVR Refining is subject to price fluctuations caused by supply conditions, weather, economic conditions, interest rate fluctuations and other factors. To manage price risk on crude oil and other inventories and to fix margins on certain future production, CVR Refining from time to time enters into various commodity derivative transactions. CVR Refining does not apply hedge accounting with respect to derivative instruments held. Gains or losses related to the change in fair value and periodic settlements of these derivative instruments are classified as gain (loss) on derivatives, net in the Condensed Consolidated Statements of Operations. CVR Refining has adopted accounting standards which impose extensive record-keeping requirements in order to designate a derivative financial instrument as a hedge. CVR Refining holds derivative instruments, such as exchange-traded crude oil futures and certain over-the-counter forward swap agreements, which it believes provide an economic hedge on future transactions, but such instruments are not designated as hedges under GAAP. There are no premiums paid or received at inception of the derivative contracts and upon settlement. CVR Refining enters into commodity swap contracts in order to fix the margin on a portion of future production. Additionally, CVR Refining may enter into price and basis swaps in order to fix the price on a portion of its commodity purchases and product sales. The physical volumes are not exchanged and these contracts are net settled with cash. The contract fair value of the commodity swaps is reflected on the Condensed Consolidated Balance Sheets with changes in fair value currently recognized in the Condensed Consolidated Statements of Operations. Quoted prices for similar assets or liabilities in active markets (Level 2) are considered to determine the fair values for the purpose of marking to market the hedging instruments at each period end. A change of $1.00 per barrel in the fair value of the benchmark crude or product basis would result in an increase or decrease in the related fair value of the commodity instruments and forward purchase and sale commitments of $2.0 million .

Each of the counterparty agreements provides for the right to setoff each individual derivative position to arrive at the net receivable due from the counterparty or payable owed by CVR Refining. As a result of the right to setoff, CVR Refining's recognized assets and liabilities associated with the outstanding commodity swap derivative positions have been presented net in the Condensed Consolidated Balance Sheets. The tables below outline the gross amounts of the recognized assets and liabilities and the gross amounts offset in the Condensed Consolidated Balance Sheets for the various types of open derivative positions. The offsetting assets and liabilities for CVR Refining's derivatives as of June 30, 2018 and December 31, 2017 are recorded as current assets and current liabilities in prepaid expenses and other current assets and accrued expenses and other current liabilities, respectively, in the Condensed Consolidated Balance Sheets as follows: As of June 30, 2018 Description Gross Current Assets Gross Net Current Assets Cash Net (in millions) Commodity Derivatives $ 6 $ (5 ) $ 1 $ — $ 1 Total $ 6 $ (5 ) $ 1 $ — $ 1 As of June 30, 2018 Description Gross Current Liabilities Gross Amounts Offset Net Current Liabilities Presented Cash Collateral Not Offset Net Amount (in millions) Commodity Derivatives $ 32 $ (5 ) $ 27 $ — $ 27 Total $ 32 $ (5 ) $ 27 $ — $ 27 As of December 31, 2017 Description Gross Current Assets Gross Amounts Offset Net Current Assets Presented Cash Collateral Not Offset Net Amount (in millions) Commodity Derivatives $ 7 $ (7 ) $ — $ — $ — Total $ 7 $ (7 ) $ — $ — $ — As of December 31, 2017 Description Gross Current Liabilities Gross Amounts Offset Net Current Liabilities Presented Cash Collateral Not Offset Net Amount (in millions) Commodity Derivatives $ 71 $ (7 ) $ 64 $ — $ 64 Total $ 71 $ (7 ) $ 64 $ — $ 64

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and in accordance with the rules and regulations of the Securities and Exchange Commission (the "SEC"). These condensed consolidated financial statements should be read in conjunction with the December 31, 2017 audited consolidated financial statements and notes thereto included in CVR Refining's Annual Report on Form 10-K for the year ended December 31, 2017 , which was filed with the SEC on February 26, 2018 (the " 2017 Form 10-K"). The condensed consolidated financial statements include certain selling, general and administrative expenses (exclusive of depreciation and amortization) and direct operating expenses (exclusive of depreciation and amortization) that CVR Energy and its affiliates incurred on behalf of and charged to the Partnership. These related party transactions are governed by the services agreement. See Note 14 ("Related Party Transactions") for additional discussion of the services agreement and billing of certain costs. In the opinion of the Partnership's management, the accompanying condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that are necessary to fairly present the financial position of the Partnership as of June 30, 2018 and December 31, 2017 , the results of operations of the Partnership for the three and six month periods ended June 30, 2018 and 2017 and the cash flows of the Partnership for the six month periods ended June 30, 2018 and 2017 . Certain information has been reclassified to present historical information in a manner consistent with current presentation. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Results of operations and cash flows for the interim periods presented are not necessarily indicative of the results that will be realized for the year ending December 31, 2018 or any other interim or annual period.
Recent Accounting Pronouncements	Adoption of New Revenue Standard On January 1, 2018, the Partnership adopted the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 606, "Revenue from Contracts with Customers" (“ASC 606”) using the modified retrospective method applied to contracts which were not completed as of January 1, 2018. The standard was applied prospectively and the comparative information for 2017 has not been restated and continues to be reported under the accounting standards in effect for the prior period. The Partnership did not identify any material differences in its existing revenue recognition methods that require modification under the new standard and, as such, a cumulative effect adjustment of applying the standard using the modified retrospective method was not recorded. Impact on Financial Statements The Partnership identified a presentation change associated with a fee collected from certain customers that were previously recorded as a reduction to cost of materials and other. The particular fee, the Oil Spill Liability Tax, relates to taxes imposed on refineries as part of the crude oil procurement process, and is charged to certain of the Partnership’s customers on product sales and is required under the new standard to be included in the transaction price. The impact of the change in presentation was an increase of $1 million to net sales and cost of materials and other for the three and six months ended June 30, 2018 . New Accounting Standards Issued But Not Yet Implemented In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, “Leases” (“ASU 2016-02”) creating a new topic, FASB ASC Topic 842, "Leases," which supersedes lease requirements in FASB ASC Topic 840, "Leases." The new standard revises accounting for operating leases by a lessee, among other changes, and requires a lessee to recognize a liability related to future lease payments and an asset representing its right to use the underlying asset for the lease term in the balance sheet. Quantitative and qualitative disclosures, including disclosures regarding significant judgments made by management, will be required. The standard is effective for the first interim and annual periods beginning after December 15, 2018, with early adoption permitted. At adoption, ASU 2016-02 will be applied using the modified retrospective application method and allows for certain practical expedients. The Partnership has begun its assessment and implementation plan for its planned adoption effective January 1, 2019. The Partnership expects the impact of the new lease standard to be material with respect to its balance sheet and further expect impacts to disclosures and changes in internal lease accounting processes.
