Description Of Business And Basis Of Presentation [Abstract]	'
Description Of Business And Basis Of Presentation	'
	Note 1 — Description of Business and Basis of Presentation
	Description of business — The business of Murphy USA Inc. (“Murphy USA” or the “Company”) and its subsidiaries primarily consists of the U.S. retail marketing business that was separated from its former parent company, Murphy Oil Corporation (“Murphy Oil” or “Parent”), plus an ethanol production facility and other assets, liabilities and operating expenses of Murphy Oil that were associated with supporting the activities of the U.S. retail marketing operations.  The separation was approved by the Murphy Oil board of directors on August 7, 2013, and was completed on August 30, 2013 through the distribution of 100% of the outstanding capital stock of Murphy USA to holders of Murphy Oil common stock on the record date of August 21, 2013. Murphy Oil stockholders of record received one share of Murphy USA common stock for every four shares of Murphy Oil common stock. The spin-off was completed in accordance with a separation and distribution agreement entered into between Murphy Oil and Murphy USA. Following the separation, Murphy USA is an independent, publicly traded company, and Murphy Oil retains no ownership interest in Murphy USA.
	Murphy USA markets refined products through a network of retail gasoline stations and unbranded wholesale customers. Murphy USA’s owned retail stations are almost all located in close proximity to Walmart stores in 23 states and use the brand name Murphy USA®. Murphy USA also markets gasoline and other products at standalone stations under the Murphy Express brand. At June 30, 2014, Murphy USA had a total of 1,223 Company stations. In October 2009, Murphy USA acquired an ethanol production facility located in Hankinson, North Dakota, which was subsequently sold in December 2013 and is reflected as discontinued operations for all periods presented.  The Company also acquired a partially constructed ethanol production facility in Hereford, Texas, in late 2010. The Hereford facility is designed to produce 105 million gallons of corn-based ethanol per year, and it began operations near the end of the first quarter of 2011.
	The contributed assets of Murphy Oil included in the Company’s financial statements also include buildings, real estate, an airplane and computer equipment and software that are used to support the operating activities of Murphy USA.
	Basis of Presentation — Murphy USA was incorporated in March 2013 and, in connection with its incorporation, Murphy USA issued 100 shares of common stock, par value $0.01 per share, to Murphy Oil for $1.00. Murphy USA was formed solely in contemplation of the separation and until the separation was completed on August 30, 2013, it had not commenced operations and had no material assets, liabilities, or commitments.  Accordingly the accompanying consolidated and combined financial statements reflect the combined historical results of operations, financial position and cash flows of the Murphy Oil subsidiaries and certain assets, liabilities and operating expenses of Murphy Oil that comprise Murphy USA, as described above, as if such companies and accounts had been combined for all periods presented prior to August 30, 2013. All significant intercompany transactions and accounts within the combined financial statements have been eliminated.
	The assets and liabilities in these consolidated and combined financial statements at June 30,  2014 have been reflected on a historical basis.   Any periods presented that include dates prior to August 30, 2013 are periods when all of the assets and liabilities shown were 100 percent owned by Murphy Oil and represented operations of Murphy USA prior to the separation.  For the period prior to separation, the consolidated and combined statements of income also include expense allocations for certain corporate functions historically performed by Murphy Oil, including allocations of general corporate expenses related to executive oversight, accounting, treasury, tax, legal, procurement and information technology. These allocations are based primarily on specific identification, headcount or computer utilization. Murphy USA’s management believes the assumptions underlying the consolidated and combined financial statements, including the assumptions regarding the allocation of general corporate expenses from Murphy Oil, are reasonable. However, these consolidated and combined financial statements may not include all of the actual expenses that would have been incurred had the Company been a stand-alone company during the period prior to separation and may not reflect the combined results of operations, financial position and cash flows had the Company been a stand-alone company during the entirety of the periods presented.
	Actual costs that would have been incurred if Murphy USA had been a stand-alone company for the period prior to separation would depend upon multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure.
	In preparing the financial statements of Murphy USA in conformity with accounting principles generally accepted in the United States, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results may differ from these estimates.
	Interim Financial Information — The interim period financial information presented in these consolidated and combined financial statements is unaudited and includes all known accruals and adjustments, in the opinion of management, necessary for a fair presentation of the consolidated and combined financial position of Murphy USA and its results of operations and cash flows for the periods presented. All such adjustments are of a normal and recurring nature.
	These interim consolidated and combined financial statements should be read together with our audited financial statements for the years ended December 31, 2013, 2012 and 2011, included in our Annual Report on Form 10-K (File No. 001-35914), as filed with the Securities and Exchange Commission under the Securities Exchange Act of 1934 on February 28, 2014.
	Recently Issued Accounting Standards— In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which changes the requirements for reporting discontinued operations under Accounting Standards Codification Topic 205. Under ASU No. 2014-08, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The standard states that a strategic shift could include a disposal of (i) a major geographical area of operations, (ii) a major line of business, (iii) a major equity method investment or (iv) other major parts of an entity. ASU No. 2014-08 no longer precludes presentation as a discontinued operation if (i) there are operations and cash flows of the component that have not been eliminated from the reporting entity’s ongoing operations or (ii) there is significant continuing involvement with a component after its disposal. Additional disclosures about discontinued operations will also be required. The guidance is effective for annual periods beginning on or after December 15, 2014, and is to be applied prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The Company expects to adopt ASU No. 2014-08 on a prospective basis beginning January 1, 2015.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers," which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the new ASU No. 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. The guidance is effective for annual and interim periods beginning after December 15, 2016, with early adoption prohibited. The Company expects to adopt ASU No. 2014-09 beginning January 1, 2017 and is in the process of assessing the impact that the new guidance will have on the Company's results of operations, financial condition and disclosures.

Related-Party Transactions [Abstract]	'
Related-Party Transactions	'
	Note 2 — Related Party Transactions
	Related party transactions of the Company include the allocation of certain general and administrative costs from Murphy Oil to the Company and receipt of interest income from Murphy Oil for intercompany payables balances for the periods prior to separation from Murphy Oil.
	General and administrative costs were charged by Murphy Oil to the Company based on management’s determination of such costs attributable to the operations of the Company. However, such related-party transactions cannot be presumed to be carried out on an arm’s length basis as the requisite conditions of competitive, free-market dealings may not exist.
	Prior to the separation Murphy Oil provided cash management services to the Company. As a result, the Company generally remitted funds received to Murphy Oil, and Murphy Oil paid all operating and capital expenditures on behalf of the Company. Such cash transactions were reflected in the change in the Net Investment by Parent.
	The Consolidated and Combined Statements of Income include expense allocations for certain functions provided to the Company by Murphy Oil prior to the separation. If possible, these allocations were made on a specific identification basis. Otherwise, the expenses related to services provided to the Company by Murphy Oil were allocated to Murphy USA based on relative percentages, as compared to Murphy Oil’s other businesses, of headcount or other appropriate methods depending on the nature of each item of cost to be allocated.
	Charges for functions historically provided to the Company by Murphy Oil were primarily attributable to Murphy Oil’s performance of many shared services that the Company benefitted from, such as treasury, tax, accounting, risk management, legal, internal audit, procurement, human resources, investor relations and information technology. Murphy USA also participated in certain Murphy Oil insurance, benefit and incentive plans. The Consolidated and Combined Statements of Income reflect charges from Murphy Oil and its other subsidiaries for these services of $0 and $16,091,000 for the three months ended June 30, 2014 and 2013, respectively, and $0 and $36,740,000 for the six months ended June 30, 2014 and 2013, respectively. Included in the charges above are amounts recognized for stock-based compensation expense (Note 8), as well as net periodic benefit expense associated with the Parent’s retirement plans (Note 9).
	Included in Interest income in the Consolidated and Combined Statements of Income for the three months ended June 30, 2014 and 2013 was interest income from affiliates of $0 and $453,000, respectively.  For the six months ended June 30, 2014 and 2013 interest income from affiliates was $0 and $727,000, respectively.  These amounts were paid on balances that were previously intercompany prior to the separation from Murphy Oil and were settled in full at the separation date.
	Transition Services Agreement
	In conjunction with the separation, we entered into a Transition Services Agreement with Murphy Oil on August 30, 2013.  This Transition Services Agreement sets forth the terms on which Murphy Oil provides to us, and we provide to Murphy Oil, on a temporary basis, certain services or functions that the companies have historically shared.  Transition services include administrative, payroll, human resources, information technology and network transition services, tax, treasury and other support and corporate services.  The Transition Services Agreement provides for the provision of specified transition services generally for a period of up to eighteen months, with a possible extension of six months, on a cost basis.  We record the fee Murphy Oil charges us for these services as a component of general and administrative expenses.
	We believe that the operating expenses and general and administrative expenses allocated to us prior to the separation and included in the accompanying consolidated and combined statements of income were a reasonable approximation of the costs related to Murphy USA’s operations.  However, such related-party transactions cannot be presumed to be carried out on an arm’s-length basis as the terms were negotiated while Murphy USA was still a subsidiary of Murphy Oil.  At June 30, 2014, Murphy USA had a current receivable from Murphy Oil of $70,000 and a payable to Murphy Oil of $988,000 related to the Transition Services Agreement.

Discontinued Operations	'
	Note 3 – Discontinued Operations
	In November 2013, the Company announced that it had entered into negotiations to sell its Hankinson, North Dakota ethanol production facility as part of management’s strategic plan to exit non-core businesses. On December 19, 2013, the Company sold its wholly-owned subsidiary Hankinson Renewable Energy, LLC which owned and operated an ethanol manufacturing facility in Hankinson, North Dakota, and its related assets for $170,000,000 plus working capital adjustments of approximately $3,118,000. During January 2014, the final adjustments to working capital were made and the Company received an additional $1.1 million in sales proceeds which has been included in discontinued operations for the period.  The Company has accounted for all operations related to Hankinson Renewable, LLC as discontinued operations for all periods presented. The after-tax gain from disposal of the subsidiary (including associated inventories) was $52,542,000 in 2013 with an additional $781,000 in 2014 related to the final working capital adjustment.
	The results of operations associated with the Hankinson discontinued operations for the 2013 period are presented in the following table.

Corn based products consisted primarily of corn, dried distillers’ grains with solubles (DDGS) and wet distillers’ grains with solubles (WDGS), and were all valued on a first-in, first-out (FIFO) basis.
	In the first quarter of 2014, the Company recognized a benefit of $17,781,000 related to a LIFO decrement that existed at that date that is not expected to be restored at year-end.

	Senior Notes
	On August 14, 2013, Murphy Oil USA, Inc., our primary operating subsidiary, issued 6.00% Senior Notes due 2023 (the “Senior Notes”) in an aggregate principal amount of $500 million. The Senior Notes are fully and unconditionally guaranteed by Murphy USA, and are guaranteed by certain 100% owned subsidiaries that guarantee our credit facilities. The indenture governing the Senior Notes contains restrictive covenants that limit, among other things, the ability of Murphy USA, Murphy Oil USA, Inc. and the restricted subsidiaries to incur additional indebtedness or liens, dispose of assets, make certain restricted payments or investments, enter into transactions with affiliates or merge with or into other entities.
	The Senior Notes and the guarantees rank equally with all of our and the guarantors’ existing and future senior unsecured indebtedness and effectively junior to our and the guarantors’ existing and future secured indebtedness (including indebtedness with respect to the credit facilities) to the extent of the value of the assets securing such indebtedness.  The Senior Notes are structurally subordinated to all of the existing and future third-party liabilities, including trade payables, of our existing and future subsidiaries that do not guarantee the notes.
	We used the net proceeds of the Senior Notes, together with borrowings under the credit facilities, to finance a cash dividend of $650 million from Murphy Oil USA, Inc. to Murphy Oil paid in connection with the separation.
	On June 17, 2014, we closed an exchange offer for our Senior Notes to make them eligible for public resale, as required by a registration rights agreement entered into in connection with the issuance of the Senior Notes.  Approximately 99.96% of the Senior Notes were tendered for exchange.
	Credit Facilities
	On August 30, 2013, we entered into a credit agreement in connection with the separation from Murphy Oil. The credit agreement provides for a committed $450 million asset-based loan (ABL) facility (with availability subject to the borrowing base described below) and a $150 million term facility. It also provides for a $200 million uncommitted incremental facility. The ABL facility is scheduled to mature on August 30, 2018, subject to the ability to extend for two additional one-year periods with the consent of the extending lenders. On August 30, 2013, Murphy Oil USA, Inc. borrowed $150 million under the term facility, together with the net proceeds of the offering of the Senior Notes, to finance a  $650 million cash dividend from Murphy Oil USA, Inc. to Murphy Oil. The term facility was scheduled to mature on August 30, 2016, but was repaid in full in May 2014.
	The borrowing base is expected, at any time of determination, to be an amount (net of reserves) equal to the sum of:
	•      100% of eligible cash at such time, plus
	•      90% of eligible credit card receivables at such time, plus
	•      90% of eligible investment grade accounts, plus
	•      85% of eligible other accounts, plus
	•      80% of eligible product supply/wholesale refined products inventory at such time, plus
	•      75% of eligible retail refined products inventory at such time, plus
	the lesser of (i) 70% of the average cost of eligible retail merchandise inventory at such time and (ii) 85% of the net orderly liquidation value of eligible retail merchandise inventory at such time.
	The ABL facility includes a $75 million sublimit on swingline loans and a $200 million sublimit for the issuance of letters of credit. Swingline loans and letters of credit issued under the ABL facility reduce availability under the ABL facility.
	Interest payable on the credit facilities is based on either:
	•    the London interbank offered rate, adjusted for statutory reserve requirements (the “Adjusted LIBO Rate”); or
	•the Alternate Base Rate, which is defined as the highest of (a) the prime rate, (b) the federal funds effective rate from time to time plus 0.50% per annum and (c) the one-month Adjusted LIBO Rate plus 1.00% per annum,
	plus, (A) in the case of Adjusted LIBO Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 1.50% to 2.00% per annum depending on the average availability under the ABL facility or (ii) with respect to the term facility, spreads ranging from 2.75% to 3.00% per annum depending on a secured debt to EBITDA ratio and (B) in the case of Alternate Base Rate borrowings, (i) with respect to the ABL facility, spreads ranging from 0.50% to 1.00% per annum depending on the average availability under the ABL facility or (ii) with respect to the term facility, spreads ranging from 1.75% to 2.00% per annum depending on a secured debt to EBITDA ratio.
	The interest rate period with respect to the Adjusted LIBO Rate interest rate option can be set at one,  two,  three, or six months as selected by us in accordance with the terms of the credit agreement.
	We were obligated to make quarterly principal payments on the outstanding principal amount of the term facility beginning on the first anniversary of the effective date of the credit agreement in amounts equal to 10% of the term loans made on such effective date, with the remaining balance payable on the scheduled maturity date of the term facility. Borrowings under the credit facilities are prepayable at our option without premium or penalty. We were also required to prepay the term facility with the net cash proceeds of certain asset sales or casualty events, subject to certain exceptions. The credit agreement also includes certain customary mandatory prepayment provisions with respect to the ABL facility.
	The credit agreement contains certain covenants that limit, among other things, the ability of us and our subsidiaries to incur additional indebtedness or liens, to make certain investments, to enter into sale-leaseback transactions, to make certain restricted payments, to enter into consolidations, mergers or sales of material assets and other fundamental changes, to transact with affiliates, to enter into agreements restricting the ability of subsidiaries to incur liens or pay dividends, or to make certain accounting changes. In addition, the credit agreement requires us to maintain a fixed charge coverage ratio of a minimum of 1.0 to 1.0 when availability for at least three consecutive business days is less than the greater of (a) 17.5% of the lesser of the aggregate ABL facility commitments and the borrowing base and (b) $70,000,000 (including as of the most recent fiscal quarter end on the first date when availability is less than such amount).  As of June 30, 2014, our fixed charge coverage ratio was 1.03.  Prior to the repayment of the term loan, we were also subject to a maximum secured debt to EBITDA ratio of 4.5 to 1.0 at any time when term facility commitments or term loans thereunder were outstanding.
	After giving effect to the applicable restrictions on certain payments, which could include dividends under the credit agreement and the indenture, and subject to compliance with applicable law, as of December 31, 2013, the Company had approximately $26.7 million of its net income and retained earnings free of such restrictions.
	All obligations under the credit agreement are guaranteed by Murphy USA and the subsidiary guarantors party thereto, and all obligations under the credit agreement, including the guarantees of those obligations, are secured by certain assets of Murphy USA, Murphy Oil USA, Inc. and the guarantors party thereto.

	Note 6 — Asset Retirement Obligations (ARO)
	The majority of the ARO recognized by the Company at June 30, 2014 and December 31, 2013 related to the estimated costs to dismantle and abandon certain of its retail gasoline stations. The Company has not recorded an ARO for certain of its marketing assets because sufficient information is presently not available to estimate a range of potential settlement dates for the obligation. These assets are consistently being upgraded and are expected to be operational into the foreseeable future. In these cases, the obligation will be initially recognized in the period in which sufficient information exists to estimate the obligation.
	A reconciliation of the beginning and ending aggregate carrying amount of the ARO is shown in the following table.

	Balance at end of period	$	18,077	$	17,130
	The estimation of future ARO is based on a number of assumptions requiring professional judgment. The Company cannot predict the type of revisions to these assumptions that may be required in future periods due to the lack of availability of additional information.

Income Taxes	'
	Note 7— Income Taxes
	The effective tax rate is calculated as the amount of income tax expense divided by income before income tax expense. For the three month and six month periods ended June 30, 2014 and 2013, the Company’s effective tax rates were as follows:
		2014	2013
	Three months ended June 30	31.9%	38.9%
	Six months ended June 30	32.8%	39.4%
	The effective tax rate for the three month and six month periods ended June 30, 2014 is lower than the U.S. Federal statutory rate due to a tax benefit recorded in the period to lower the effective state tax rate.  This adjustment to a lower state tax rate generated a benefit of $6.8 million that was recorded during the second quarter of 2014.  The effective tax rate for the three months ended June 30, 2013 exceeded the U.S. Federal tax rate of 35% primarily due to U.S. state tax expense.
	The Company was included in Murphy Oil’s tax returns for the periods prior to the separation in multiple jurisdictions that remain subject to audit by taxing authorities. These audits often take years to complete and settle. As of June 30, 2014, the earliest year remaining open for audit and/or settlement in the United States is 2010.  Although the Company believes that recorded liabilities for unsettled issues are adequate, additional gains or losses could occur in future periods from resolution of outstanding unsettled matters.
	Under U.S. GAAP the financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. The Company has not recorded any effect for unrecognized income tax benefits for the periods reported.

Incentive Plans	'
	Note 8 — Incentive Plans
	Prior to the separation and distribution, our employees participated in the Murphy Oil 2007 Long-Term Incentive Plan (the “2007 Plan”) and the Murphy Oil 2012 Long-Term Incentive Plan (the “2012 Plan”) and received Murphy Oil restricted stock awards and options to purchase shares of Murphy Oil common stock. While participating in these two plans, costs resulting from share-based payment transactions were allocated and recognized as an expense in the financial statements using a fair value-based measurement method over the periods that the awards vested. Certain employees of the Company have received annual grants in the form of Murphy Oil stock options, restricted stock units and other forms of share based payments prior to the separation and distribution. Accordingly, the Company has accounted for expense for these plans in accordance with SAB Topic 1-B for periods prior to the separation and distribution.
	2013 Long-Term Incentive Plan
	Effective August 30, 2013, certain of our employees participate in the Murphy USA 2013 Long-Term Incentive Plan which was subsequently amended and restated effective as of February 12, 2014 (the “MUSA 2013 Plan”). The MUSA 2013 Plan authorizes the Executive Compensation Committee of our Board of Directors (“the Committee”) to grant non-qualified or incentive stock options, stock appreciation rights, stock awards (including restricted stock and restricted stock unit awards), cash awards, and performance awards to our employees. No more than 5.5 million shares of MUSA common stock may be delivered under the MUSA 2013 Plan and no more than 1 million shares of common stock may be awarded to any one employee, subject to adjustment for changes in capitalization. The maximum cash amount payable pursuant to any “performance-based” award to any participant in any calendar year is $5 million.
	On February 11, 2014, the Committee granted nonqualified stock options for 127,400 shares at an exercise price of $39.46 per share under the terms of the MUSA 2013 Plan.  The Black-Scholes valuation for these awards is $11.44 per option.  The Committee also awarded time-based restricted stock units and performance-based restricted stock units (performance units) to certain employees on the same date.   There were 39,250 time-based restricted units granted at a grant date fair value of $39.46 along with 78,500 performance units.  Half of the performance units vest based on a 3-year return on average capital employed (ROACE) calculation and the other half vest based on a 3-year total shareholder return (TSR) calculation that compares MUSA to a group of 17 peer companies.  The portion of the awards that vest based on TSR qualify as a market condition and must be valued using a Monte Carlo valuation model.  For the TSR portion of the awards, the fair value was determined to be $43.41 per unit.  For the ROACE portion of the awards, the valuation will be based on the grant date fair value of $39.46 per unit and the number of awards will be periodically assessed to determine the probability of vesting.
	On March 3, 2014, the Committee also granted 53,475 time-based restricted stock units granted to certain employees with a grant date fair value of $40.00 per unit.
	2013 Stock Plan for Non-employee Directors
	Effective August 8, 2013, Murphy USA adopted the 2013 Murphy USA Stock Plan for Non-employee Directors (the “Directors Plan”).  The directors for Murphy USA are compensated with a mixture of cash payments and equity-based awards.  Awards under the Directors Plan may be in the form of restricted stock, restricted stock units, stock options, or a combination thereof.  An aggregate of 500,000 shares of common stock shall be available for issuance of grants under the Directors Plan.
	During the first quarter of 2014, the Company issued 22,437 restricted stock units to its non-employee directors at a weighted average grant date fair value of $39.07 per share.  These shares vest in three years from the grant date.
	For the six months ended June 30, 2014 and 2013, share based compensation was $4.8 million and $4.3 million, respectively.  For the six months ended June 30, 2014 and 2013, cash received from options exercised under all share-based payment arrangements was not material.  The related income tax benefit realized for the tax deductions from options exercised for the six months ended June 30, 2014 and 2013, was not material.
	As of June 30, 2014, unrecognized compensation cost related to stock option awards was $3.2 million, which is expected to be recognized over a weighted average period of 1.8 years. Unrecognized compensation cost related to restricted stock awards was $16.3 million, which is expected to be recognized over a weighted average period of 2.5 years.

	Note 9 — Employee and Retiree Benefit Plans
	PENSION AND POSTRETIREMENT PLANS — Murphy Oil has defined benefit pension plans that are principally noncontributory and cover most full-time employees. Upon separation from Murphy Oil, all amounts for these plans related to Murphy USA were frozen and retained by Murphy Oil. Therefore, the assets and liabilities related to Murphy USA employees in these plans are not included in these financial statements as Murphy USA is considered to be participating in multiple employer benefit plans due to co-mingling of various plan assets. However, the periodic benefit expense for each period includes the expense of the U.S. benefit plans. All U.S. tax qualified plans meet the funding requirements of federal laws and regulations. Murphy Oil also sponsors health care and life insurance benefit plans, which are not funded, that cover most retired U.S. employees. The health care benefits are contributory; the life insurance benefits are noncontributory. Murphy USA does not expect to have similar pension or post-retirement plans for its employees.
	The table that follows provides the components of net periodic benefit expense associated with Company employees for the three months and six months ended June 30, 2013 as there was no comparable expense for the three months and six months ended June 30, 2014.

	U.S. Health Care Reform — In March 2010, the United States Congress enacted a health care reform law. Along with other provisions, the law (a) eliminated the tax free status of federal subsidies to companies with qualified retiree prescription drug plans that are actuarially equivalent to Medicare Part D plans beginning in 2013; (b) imposes a 40% excise tax on high-cost health plans as defined in the law beginning in 2018; (c) eliminated lifetime or annual coverage limits and required coverage for preventative health services beginning in September 2010; and (d) imposed a fee of $2 (subsequently adjusted for inflation) for each person covered by a health insurance policy beginning in September 2010. The new law did not significantly affect the Company’s consolidated and combined financial statements as of June 30, 2014 and December 31, 2013 and for the three month or six month periods ended June 30, 2014 and 2013.

Note 10— Financial Instruments and Risk Management

DERIVATIVE INSTRUMENTS — The Company makes limited use of derivative instruments to manage certain risks related to commodity prices. The use of derivative instruments for risk management is covered by operating policies and is closely monitored by the Company’s senior management. The Company does not hold any derivatives for speculative purposes and it does not use derivatives with leveraged or complex features. Derivative instruments are traded primarily with creditworthy major financial institutions or over national exchanges such as the New York Mercantile Exchange (“NYMEX”). To qualify for hedge accounting, the changes in the market value of a derivative instrument must historically have been, and would be expected to continue to be, highly effective at offsetting changes in the prices of the hedged item. To the extent that the change in fair value of a derivative instrument has less than perfect correlation with the change in the fair value of the hedged item, a portion of the change in fair value of the derivative instrument is considered ineffective and would normally be recorded in earnings during the affected period.

The Company is subject to commodity price risk related to corn that it will purchase in the future for feedstock and WDGS that it will sell in the future at its remaining ethanol production facility.  At June 30, 2014 and 2013, the Company had open physical delivery commitment contracts for purchase of approximately 4.9 million and 17.2 million bushels of corn, respectively, for processing at its ethanol plants. For the periods ended June 30, 2014 and 2013, the Company had open physical delivery commitment contracts for sale of approximately 0.8 million and 1.4 million equivalent bushels, respectively, of DDGS and WDGS. To manage the price risk associated with certain of these physical delivery commitments which have fixed prices, at June 30, 2014 and 2013, the Company had outstanding derivative contracts with offsetting long and short volumes of 2.3 million and 13.4 million bushels, respectively, that mature at future prices in effect on the expected date of delivery under the physical delivery commitment contracts.   Additionally, at June 30, 2014 and 2013, the Company had outstanding derivative contracts with a net short volume of 1.7 million and 2.3 million bushels of corn, respectively, to buy back when certain corn inventories are expected to be processed. The impact of marking to market these commodity derivative contracts increased income before taxes by $0.9 million and increased income before taxes by $1.2 million for the six months ended June 30, 2014 and 2013, respectively.

At June 30, 2014 and December 31, 2013, the fair value of derivative instruments not designated as hedging instruments are presented in the following table.

These contracts permit net settlement and the Company generally avails itself of this right to settle net. At June 30, 2014 and December 31, 2013, cash deposits of $2.8 million and $2.9 million related to commodity derivative contracts were reported in Prepaid Expenses in the Consolidated Balance Sheets, respectively. These cash deposits have not been used to reduce the reported net liabilities on the corn-based derivative contracts at June 30, 2014 or December 31, 2013.

Earnings Per Share	'
	Note 11 – Earnings Per Share
	Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted average of common shares outstanding during the period.  Diluted earnings per common share adjusts basic earnings per common share for the effects of stock options and restricted stock in the periods where such items are dilutive.
	On August 30, 2013, 46,743,316 shares of our common stock were distributed to the shareholders of Murphy Oil in connection with the separation and distribution.  For comparative purposes, we have assumed this amount to be outstanding as of the beginning of each prior period prior to the separation and distribution presented in the calculation of weighted average shares outstanding.
	During May 2014, the Company executed a share repurchase program that was approved by the Board of Directors for approximately $50 million worth of common stock of the Company.   At the completion of this plan, the Company had acquired 1,040,636 shares of common stock for an average price of $48.07 per share including brokerage fees.
	The following table provides a reconciliation of basic and diluted earnings per share computations for the three months and six months ended June 30, 2014 and 2013 (in thousands, except per share amounts):

Assets And Liabilities Measure At Fair Value	'
	Note 13 — Assets and Liabilities Measured at Fair Value
	The Company carries certain assets and liabilities at fair value in its Consolidated Balance Sheets. The fair value hierarchy is based on the quality of inputs used to measure fair value, with Level 1 being the highest quality and Level 3 being the lowest quality. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1. Level 3 inputs are unobservable inputs which reflect assumptions about pricing by market participants.
	The Company carries certain assets and liabilities at fair value in its Consolidated Balance Sheets. The fair value measurements for these assets and liabilities at June 30, 2014 and December 31, 2013 are presented in the following table.

	At the balance sheet date the fair value of commodity derivatives contracts for corn was determined based on market quotes for No. 2 yellow corn. The change in fair value of commodity derivatives is recorded in Fuel and ethanol cost of goods sold. The carrying value of the Company’s Cash and cash equivalents, Accounts receivable-trade and Trade accounts payable approximates fair value due to their short-term nature.
	The following table presents the carrying amounts and estimated fair values of financial instruments held by the Company at June 30, 2014 and December 31, 2013. The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. The table excludes Cash and cash equivalents, Accounts receivable-trade, and Trade accounts payable and accrued liabilities, all of which had fair values approximating carrying amounts. The fair value of Current and Long-term debt was estimated based on rates offered to the Company at that time for debt of the same maturities. The Company has off-balance sheet exposures relating to certain financial guarantees and letters of credit. The fair value of these, which represents fees associated with obtaining the instruments, was nominal.

Commitments And Contingencies [Abstract]	'
Contingencies	'
	Note 14 — Contingencies
	The Company’s operations and earnings have been and may be affected by various forms of governmental action. Examples of such governmental action include, but are by no means limited to: tax increases and retroactive tax claims; import and export controls; price controls; allocation of supplies of crude oil and petroleum products and other goods; laws and regulations intended for the promotion of safety and the protection and/or remediation of the environment; governmental support for other forms of energy; and laws and regulations affecting the Company’s relationships with employees, suppliers, customers, stockholders and others. Because governmental actions are often motivated by political considerations, may be taken without full consideration of their consequences, and may be taken in response to actions of other governments, it is not practical to attempt to predict the likelihood of such actions, the form the actions may take or the effect such actions may have on the Company.
	ENVIRONMENTAL MATTERS AND LEGAL MATTERS — Murphy USA is subject to numerous federal, state and local laws and regulations dealing with the environment. Violation of such environmental laws, regulations and permits can result in the imposition of significant civil and criminal penalties, injunctions and other sanctions. A discharge of hazardous substances into the environment could, to the extent such event is not insured, subject the Company to substantial expense, including both the cost to comply with applicable regulations and claims by neighboring landowners and other third parties for any personal injury, property damage and other losses that might result.
	The Company currently owns or leases, and has in the past owned or leased, properties at which hazardous substances have been or are being handled. Although the Company believes it has used operating and disposal practices that were standard in the industry at the time, hazardous substances may have been disposed of or released on or under the properties owned or leased by the Company or on or under other locations where they have been taken for disposal. In addition, many of these properties have been operated by third parties whose management of hazardous substances was not under the Company’s control. Under existing laws the Company could be required to remediate contaminated property (including contaminated groundwater) or to perform remedial actions to prevent future contamination. Certain of these contaminated properties are in various stages of negotiation, investigation, and/or cleanup, and the Company is investigating the extent of any related liability and the availability of applicable defenses. With the sale of the U.S. refineries in 2011, Murphy Oil retained certain liabilities related to environmental matters. Murphy Oil also obtained insurance covering certain levels of environmental exposures. The Company believes costs related to these sites will not have a material adverse effect on Murphy USA’s net income, financial condition or liquidity in a future period.
	Certain environmental expenditures are likely to be recovered by the Company from other sources, primarily environmental funds maintained by certain states. Since no assurance can be given that future recoveries from other sources will occur, the Company has not recorded a benefit for likely recoveries at June 30, 2014, however certain jurisdictions provide reimbursement for these expenses which have been considered in recording the net exposure.
	The U.S. Environmental Protection Agency (EPA) currently considers the Company a Potentially Responsible Party (PRP) at one Superfund site. The potential total cost to all parties to perform necessary remedial work at this site may be substantial. However, based on current negotiations and available information, the Company believes that it is a de minimis party as to ultimate responsibility at the Superfund site. Accordingly, the Company has not recorded a liability for remedial costs at the Superfund site at June 30, 2014. The Company could be required to bear a pro rata share of costs attributable to nonparticipating PRPs or could be assigned additional responsibility for remediation at this site or other Superfund sites. The Company believes that its share of the ultimate costs to clean-up this site will be immaterial and will not have a material adverse effect on its net income, financial condition or liquidity in a future period.
	Based on information currently available to the Company, the amount of future remediation costs to be incurred to address known contamination sites is not expected to have a material adverse effect on the Company’s future net income, cash flows or liquidity. However, there is the possibility that additional environmental expenditures could be required to address contamination, including as a result of discovering additional contamination or the imposition of new or revised requirements applicable to known contamination.
	Murphy USA is engaged in a number of other legal proceedings, all of which the Company considers routine and incidental to its business. Based on information currently available to the Company, the ultimate resolution of those other legal matters is not expected to have a material adverse effect on the Company’s net income, financial condition or liquidity in a future period.
	INSURANCE — The Company maintains insurance coverage at levels that are customary and consistent with industry standards for companies of similar size. Murphy USA maintains statutory workers compensation insurance with a deductible of $0.5 million per occurrence and other insurance programs for general and auto liability. As of June 30, 2014, there were a number of outstanding claims that are of a routine nature. The estimated incurred but unpaid liabilities relating to these claims are included in Trade account payables and accrued liabilities on the Consolidated Balance Sheets. While the ultimate outcome of these claims cannot presently be determined, management believes that the accrued liability of $4.5 million will be sufficient to cover the related liability for all insurance claims and that the ultimate disposition of these claims will have no material effect on the Company’s financial position and results of operations.
	The Company was insured under Murphy Oil’s insurance policies for occurrences prior to the completion of the separation. The specifications and insured limits under those policies, however, were at a level consistent with Murphy Oil as a whole. Following the separation, the Company has obtained insurance coverage as appropriate for the business in which it is engaged, but may incur losses that are not covered by insurance or reserves, in whole or in part, and such losses could adversely affect our results of operations and financial position.
	TAX MATTERS — Murphy USA is subject to extensive tax liabilities imposed by multiple jurisdictions, including income taxes, indirect taxes (excise/duty, sales/use and gross receipts taxes), payroll taxes, franchise taxes, withholding taxes and ad valorem taxes. New tax laws and regulations and changes in existing tax laws and regulations are continuously being enacted or proposed that could result in increased expenditures for tax liabilities in the future. Many of these liabilities are subject to periodic audits by the respective taxing authority. Subsequent changes to our tax liabilities because of these audits may subject us to interest and penalties.
	OTHER MATTERS — In the normal course of its business, the Company is required under certain contracts with various governmental authorities and others to provide financial guarantees or letters of credit that may be drawn upon if the Company fails to perform under those contracts. At June 30, 2014, the Company had contingent liabilities of $16.2 million on outstanding letters of credit. The Company has not accrued a liability in its balance sheet related to these financial guarantees and letters of credit because it is believed that the likelihood of having these drawn is remote.

	During the fourth quarter of 2013, the Company sold its Hankinson, North Dakota ethanol plant.  This was the largest of the two ethanol plants that were owned by the Company.  Because of this sale, the Company was required to reevaluate its operating segments for reporting purposes.  After reviewing the quantitative and qualitative aspects of the Company’s segments, it was determined that the remaining ethanol assets did not warrant separate segment presentation.  Therefore, the segments for the Company were restated for all prior periods to reflect one remaining operating segment, Marketing.  The remaining ethanol assets were recast into the category with the prior Corporate assets and renamed “Corporate and other assets”.  In addition, due to the sale of the Hankinson entity, the Company also shows discontinued operations for all periods presented for the prior Hankinson activity. Segment information is as follows:

Description Of Business And Basis Of Presentation [Abstract]	'
Basis Of Presentation	'
	Basis of Presentation — Murphy USA was incorporated in March 2013 and, in connection with its incorporation, Murphy USA issued 100 shares of common stock, par value $0.01 per share, to Murphy Oil for $1.00. Murphy USA was formed solely in contemplation of the separation and until the separation was completed on August 30, 2013, it had not commenced operations and had no material assets, liabilities, or commitments.  Accordingly the accompanying consolidated and combined financial statements reflect the combined historical results of operations, financial position and cash flows of the Murphy Oil subsidiaries and certain assets, liabilities and operating expenses of Murphy Oil that comprise Murphy USA, as described above, as if such companies and accounts had been combined for all periods presented prior to August 30, 2013. All significant intercompany transactions and accounts within the combined financial statements have been eliminated.
	The assets and liabilities in these consolidated and combined financial statements at June 30,  2014 have been reflected on a historical basis.   Any periods presented that include dates prior to August 30, 2013 are periods when all of the assets and liabilities shown were 100 percent owned by Murphy Oil and represented operations of Murphy USA prior to the separation.  For the period prior to separation, the consolidated and combined statements of income also include expense allocations for certain corporate functions historically performed by Murphy Oil, including allocations of general corporate expenses related to executive oversight, accounting, treasury, tax, legal, procurement and information technology. These allocations are based primarily on specific identification, headcount or computer utilization. Murphy USA’s management believes the assumptions underlying the consolidated and combined financial statements, including the assumptions regarding the allocation of general corporate expenses from Murphy Oil, are reasonable. However, these consolidated and combined financial statements may not include all of the actual expenses that would have been incurred had the Company been a stand-alone company during the period prior to separation and may not reflect the combined results of operations, financial position and cash flows had the Company been a stand-alone company during the entirety of the periods presented.
	Actual costs that would have been incurred if Murphy USA had been a stand-alone company for the period prior to separation would depend upon multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure.
	In preparing the financial statements of Murphy USA in conformity with accounting principles generally accepted in the United States, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results may differ from these estimates.
Recently Issued Accounting Standards	'
	Recently Issued Accounting Standards— In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which changes the requirements for reporting discontinued operations under Accounting Standards Codification Topic 205. Under ASU No. 2014-08, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The standard states that a strategic shift could include a disposal of (i) a major geographical area of operations, (ii) a major line of business, (iii) a major equity method investment or (iv) other major parts of an entity. ASU No. 2014-08 no longer precludes presentation as a discontinued operation if (i) there are operations and cash flows of the component that have not been eliminated from the reporting entity’s ongoing operations or (ii) there is significant continuing involvement with a component after its disposal. Additional disclosures about discontinued operations will also be required. The guidance is effective for annual periods beginning on or after December 15, 2014, and is to be applied prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The Company expects to adopt ASU No. 2014-08 on a prospective basis beginning January 1, 2015.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers," which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the new ASU No. 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. The guidance is effective for annual and interim periods beginning after December 15, 2016, with early adoption prohibited. The Company expects to adopt ASU No. 2014-09 beginning January 1, 2017 and is in the process of assessing the impact that the new guidance will have on the Company's results of operations, financial condition and disclosures.
