Organization	'
	1. Organization
	"Western," "we," "us," "our" and the "Company" refer to Western Refining, Inc. and, unless the context otherwise requires, our subsidiaries. Western Refining, Inc. was formed on September 16, 2005 as a holding company and is incorporated in Delaware.
	We are an independent crude oil refiner and marketer of refined products. We market refined products on a wholesale basis in Arizona, Colorado, California, the Mid-Atlantic region, New Mexico, the Upper Great Plains region and West Texas through bulk and rack marketing networks and we sell refined products through two retail networks with a total of 474 company-owned and franchised retail sites in the U.S. We produce refined products at three refineries: one in El Paso, Texas, one near Gallup in the Four Corners region of northern New Mexico and one in St. Paul Park, Minnesota.
	During 2013, we formed Western Refining Logistics, LP ("WNRL") and acquired control of Northern Tier Energy LP ("NTI") through our acquisition of Northern Tier Energy GP LLC, NTI's general partner. WNRL gathers, transports and stores crude oil and refined product through its pipeline and gathering assets and terminalling, transportation, asphalt and storage assets, primarily for the benefit of Western. NTI's assets are located in the Upper Great Plains region and include one refinery and supporting assets in St. Paul Park, Minnesota and retail convenience stores. Both WNRL and NTI are publicly traded limited partnerships.
	Our operations include five business segments: refining, wholesale, retail, WNRL and NTI. See Note 3, Segment Information, for further discussion of our business segments.

Basis of Presentation and Significant Accounting Policies [Text Block]	'
	2. Basis of Presentation, Significant Accounting Policies and Recent Accounting Pronouncements
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2014, are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, or for any other period.
	The Condensed Consolidated Balance Sheet at December 31, 2013, has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013.
	The condensed consolidated financial statements include the accounts of Western Refining, Inc. and subsidiaries in which we have a controlling interest. We own a 65.3% limited partner interest in WNRL and a 38.7% limited partner interest in NTI. We own 100% of WNRL's and NTI's respective general partners. As the general partner of WNRL and NTI, we have the ability to direct the activities of WNRL and NTI that most significantly impact their respective economic performance.
	Demand for gasoline is generally higher during the summer months than during the winter months. As a result, our operating results for the first and fourth calendar quarters are generally lower than those for the second and third calendar quarters of each year. During 2013 and continuing into 2014, the volatility in crude oil prices and refining margins contributed to the variability of our results of operations.
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Western and subsidiaries in which we have a controlling interest. All intercompany accounts and transactions have been eliminated for all periods presented. Investments in significant non-controlled entities are accounted for using the equity method.
	We have reported non-controlling interests for WNRL and NTI of $325.9 million and $1,361.7 million, respectively, in our Condensed Consolidated Balance Sheet as of June 30, 2014. We have reported non-controlling interest for WNRL and NTI of $326.2 million and $1,350.4 million, respectively, in our Condensed Consolidated Balance Sheet as of December 31, 2013.
	Revenue Recognition
	Revenues for products, crude oil and feedstocks sold are recorded upon delivery of the products, crude oil or feedstocks to customers; the point at which title is transferred, the customer has the assumed risk of loss and when payment has been received or collection is reasonably assured. Transportation, shipping and handling costs incurred are included in cost of products sold. Excise and other taxes collected from customers and remitted to governmental authorities are not included in revenues.
	Goodwill and Other Unamortizable Intangible Assets
	Goodwill represents the excess of the purchase price (cost) over the fair value of the net assets acquired and is carried at cost. We do not amortize goodwill for financial reporting purposes. We test goodwill for impairment at the reporting unit level. The reporting unit or units used to evaluate and measure goodwill for impairment are determined primarily from the manner in which the business is managed. Our policy is to test goodwill and other unamortizable intangible assets for impairment annually at June 30, or more frequently if indications of impairment exist.
	We conducted our annual goodwill and intangible asset valuation analysis as of June 30, 2014, noting no indications of impairment.
	Cost Classifications
	Refining cost of products sold includes cost of crude oil, other feedstocks and blendstocks, the costs of purchased refined products, transportation and distribution costs and realized and unrealized gains and losses related to our commodity hedging activities. Wholesale cost of products sold includes the cost of fuel and lubricants, transportation and distribution costs and service parts and labor. Retail cost of products sold includes costs for motor fuels and for merchandise. Motor fuel cost of products sold represents net cost for purchased fuel. Net cost of purchased fuel excludes transportation and motor fuel taxes. Merchandise cost of products sold includes merchandise purchases, net of merchandise rebates and inventory shrinkage.
	Refining direct operating expenses include direct costs of labor, maintenance materials and services, chemicals and catalysts, natural gas, utilities and other direct operating expenses. Wholesale direct operating expenses include direct costs of labor, transportation expense, maintenance materials and services, utilities and other direct operating expenses. Retail direct operating expenses include direct costs of labor, maintenance materials and services, outside services, bank charges, rent expense, utilities and other direct operating expenses. WNRL operating and maintenance expenses include labor costs, maintenance materials and services, natural gas, additives, utilities, insurance expense, property taxes and other operating expenses. NTI's direct operating expenses include direct costs of labor, maintenance materials and services, outside services, bank charges, rent expense, chemicals and catalysts, natural gas, utilities and other direct operating expenses.
	Maintenance Turnaround Expense
	Refinery process units require periodic maintenance and repairs that are commonly referred to as "turnarounds." The required frequency of the maintenance varies by unit, but generally is every two to six years depending on the processing unit involved. Turnaround costs are expensed as incurred.
	Use of Estimates
	The preparation of financial statements 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Recent Accounting Pronouncements
	Recent changes in the accounting and reporting requirements for disposals when such disposal represents a strategic shift that will have a significant impact on the entity’s operations and financial results are effective for the first interim or annual period beginning after December 15, 2014. Among other new disclosure requirements, an entity will be required to make certain disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. These new requirements will be applied prospectively. Early adoption is permitted provided the disposal was not previously disclosed. Our adoption of these changes is not expected to have a material impact on our financial position, results of operations or cash flows.
	The accounting provisions covering the recognition and reporting of revenues were amended to remove inconsistencies in revenue requirements and to provide a more complete framework for addressing revenue issues across a broad range of industries and transaction types. The revised standard’s core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. These provisions are effective for the first interim or annual period beginning after December 15, 2016, and are to be applied retrospectively, with early adoption not permitted. We do not expect the adoption of this guidance to materially affect our financial position, results of operations or cash flows.
	From time to time, new accounting pronouncements are issued by various standard setting bodies that may have an impact on our accounting and reporting. We believe that other recently issued accounting pronouncements and other authoritative guidance for which the effective date is in the future either will not have an impact on our accounting or reporting or that such impact will not be material to our financial position, results of operations or cash flows when implemented.

Segment Reporting [Abstract]	'
Segment Information	'
	3. Segment Information
	Our operations are organized into five reportable segments based on manufacturing and marketing criteria and the nature of our products and services, our production processes and our types of customers. These segments are refining, wholesale, retail, WNRL and NTI. A description of each segment's activities and principal products follows:
	Refining. We report the operations of two refineries in our refining segment: one in El Paso, Texas (the "El Paso refinery") with a 128,000 barrels per day (bpd) capacity and one near Gallup, New Mexico (the "Gallup refinery") with a 25,000 bpd capacity. Our refineries make various grades of gasoline, diesel fuel and other products from crude oil, other feedstocks and blending components. We purchase crude oil, other feedstocks and blending components from various third-party suppliers. We also acquire refined products through exchange agreements and from various third-party suppliers to supplement supply to our customers. We sell these products through our wholesale and retail segments, other independent wholesalers and retailers, commercial accounts and sales and exchanges with major oil companies.
	Wholesale. Our wholesale segment includes the operations of several lubricant and bulk petroleum distribution plants, unmanned fleet fueling operations and a fleet of refined product and lubricant delivery trucks. Our wholesale segment distributes commercial wholesale petroleum products primarily in Arizona, California, Colorado, Maryland, Nevada, New Mexico, Texas and Virginia. The wholesale segment purchases petroleum fuels and lubricants from our refining segment and from third-party suppliers. We have an exclusive supply and marketing agreement with a third party covering activities related to our refined product supply, hedging and sales in the Mid-Atlantic region. We recorded $1.5 million in liabilities and $2.3 million in assets at June 30, 2014, and December 31, 2013, respectively, related to this supply agreement in our Condensed Consolidated Balance Sheets. The revenues and costs recorded under the supply agreement included $9.5 million and $9.4 million in net hedging losses and $4.9 million and $2.3 million in net hedging gains for the three and six months ended June 30, 2014 and 2013, respectively.
	Retail. Through retail convenience stores, our retail segment sells various grades of gasoline, diesel fuel, convenience store merchandise and beverage and food products to the general public. Our wholesale segment supplies the majority of gasoline and diesel fuel that our retail segment sells. We purchase general merchandise and beverage and food products from various third-party suppliers. At June 30, 2014, the retail segment operated 229 service stations and convenience stores or kiosks located in Arizona, Colorado, New Mexico and Texas compared to 222 service stations and convenience stores or kiosks at June 30, 2013.
	WNRL. WNRL was formed to own, operate, develop and acquire logistics assets and related businesses. WNRL's assets consist of pipeline and gathering assets and terminalling, transportation and storage assets in the Southwestern portion of the U.S., including approximately 300 miles of pipelines and approximately 7.9 million barrels of active storage capacity, as well as other assets. The majority of WNRL's assets are integral to the operations of Western's refineries located in El Paso, Texas and near Gallup, New Mexico. WNRL began its operations in October 2013. WNRL's accounting predecessor's operations were historically included in our refining segment's operations and were not considered to be a separate reporting segment prior to October 2013.
	NTI. Through our acquisition of Northern Tier Energy GP LLC, NTI's general partner, Western acquired control of NTI during November 2013. NTI is an independent crude oil refiner and marketer of refined products with one 96,500 bpd refinery and also operates a network of retail convenience stores selling various grades of gasoline, diesel fuel and convenience store merchandise in the Upper Great Plains region. NTI's operations are separate from those of Western. The refined products are sold primarily in the Upper Great Plains region. As of June 30, 2014, NTI included the operations of 164 retail convenience stores and supported 81 franchised retail convenience stores. These convenience stores are located primarily in Minnesota and Wisconsin. NTI's refinery supplies the majority of the gasoline and diesel sold through these convenience stores. NTI's results of operations for the three and six months ended June 30, 2014, includes severance payments totaling $3.5 million and $12.9 million, respectively, related to Western's acquisition of NTI's general partner.
	Segment Accounting Principles. Operating income for each segment consists of net revenues less cost of products sold; direct operating expenses; selling, general and administrative expenses; net impact of the disposal of assets; maintenance turnaround expense and depreciation and amortization. Cost of products sold includes net realized and unrealized gains and losses related to our commodity hedging activities and reflects current costs adjusted, where appropriate, for "last-in, first-out" ("LIFO") and lower of cost or market inventory adjustments. Intersegment revenues are reported at prices that approximate market.
	Activities of our business that are not included in the five segments mentioned above are included in the "Other" category. These activities consist primarily of corporate staff operations and other items that are not specific to the normal business of any one of our five operating segments. We do not allocate certain items of other income and expense, including income taxes, to the individual segments. WNRL and NTI are primarily pass-through entities with respect to income taxes.
	The total assets of each segment consist primarily of cash and cash equivalents; inventories; net accounts receivable; net property, plant and equipment and other assets directly associated with the individual segment’s operations. Included in the total assets of the corporate operations are cash and cash equivalents; various net accounts receivable; prepaid expenses; other current assets; net deferred income tax items; net property, plant and equipment and other long-term assets.
	Disclosures regarding our reportable segments with reconciliations to consolidated totals for the three and six months ended June 30, 2014 and 2013, are presented below:

Fair Value Disclosures [Abstract]	'
Fair Value Measurement	'
	4. Fair Value Measurement
	We utilize the market approach when measuring fair value of our financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
	The fair value hierarchy consists of the following three levels:
	Level 1	Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.
	Level 2	Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs that are derived principally from or corroborated by observable market data.
	Level 3	Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable and cannot be corroborated by market data or other entity-specific inputs.
	The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, all of which we consider Level 1 assets and liabilities, approximated their fair values at June 30, 2014, and December 31, 2013, due to their short-term maturities. Our fair value assessment incorporates a variety of considerations, including the short-term duration of the instruments (less than one percent of our account receivables and payables are outstanding for greater than 90 days) and the expected future insignificance of bad debt expense that includes an evaluation of counterparty credit risk.
	We maintain cash deposits with various counterparties in support of our hedging and trading activities. These deposits are required by counterparties as collateral and cannot be offset against the fair value of open contracts except in the event of default. Certain of our commodity derivative contracts under master netting arrangements include both asset and liability positions. We have elected to offset the fair value amounts recognized for multiple similar derivative instruments executed with the same counterparty under the column "Netting Adjustments" below, however, fair value amounts by hierarchy level are presented on a gross basis in the tables below. See Note 13, Crude Oil and Refined Product Risk Management, for further discussion of master netting arrangements.
	The following tables represent our assets and liabilities measured at fair value on a recurring basis as of June 30, 2014 and December 31, 2013 and the basis for that measurement:

		$	(64,457	)	$	—		$	(62,522	)	$	(1,935	)	$	—		$	(64,457	)
	Commodity hedging contracts designated as Level 3 financial assets consist of jet fuel crack spread swaps. Ultra-low sulfur diesel ("ULSD") pricing has had a strong historical correlation to jet fuel crack spread swaps. We estimate the fair value of our Level 3 instruments based on the differential between quoted market settlement prices on ULSD futures and quoted market settlement prices on jet fuel futures for settlement dates corresponding to each of our outstanding Level 3 jet fuel crack spread swaps. As quoted prices for similar assets or liabilities in an active market are available, we reclassify the underlying financial asset or liability and designate them as Level 2 prior to final settlement.
	Carrying amounts of commodity hedging contracts reflected as financial assets are included in both current and non-current other assets in the Condensed Consolidated Balance Sheets. Carrying amounts of commodity hedging contracts reflected as financial liabilities are included in both accrued and other long-term liabilities in the Condensed Consolidated Balance Sheets. Fair value adjustments referred to as credit valuation adjustments ("CVA") are included in the carrying amounts of commodity hedging contracts. CVAs are intended to adjust the fair value of counterparty contracts as a function of a counterparty's credit rating and reflect the credit quality of each counterparty to arrive at contract fair values.
	The following table presents the changes in fair value of our Level 3 assets and liabilities (all related to commodity price swap contracts) for the three and six months ended June 30, 2014 and 2013.

	A hypothetical change of 10% to the estimated future cash flows attributable to our Level 3 commodity price swaps would result in a $0.4 million change in the estimated fair value.
	As of June 30, 2014 and December 31, 2013, the carrying amount and estimated fair value of our debt was as follows:
		June 30,			December 31,
		2014			2013
		(In thousands)
	Carrying amount	$	1,175,581		$	1,386,607
	Fair value	1,220,554			2,156,075
	The carrying amount of our debt is the amount reflected in the Condensed Consolidated Balance Sheets, including the current portion. The fair value of the debt was determined using Level 2 inputs.
	There have been no transfers between assets or liabilities whose fair value is determined through the use of quoted prices in active markets (Level 1) and those determined through the use of significant other observable inputs (Level 2).

	Our payment of dividends is limited under the terms of our Revolving Credit Agreement, our Senior Unsecured Notes and our Term Loan Credit Facility, and in part, depends on our ability to satisfy certain financial covenants.
	Revolving Credit Facility
	On April 11, 2013, we entered into the Second Amended and Restated Revolving Credit Agreement ("Western Revolving Credit Facility"). Lenders under the Western Revolving Credit Facility extended $900.0 million in commitments that mature on April 11, 2018 and incorporate a borrowing base tied to eligible accounts receivable and inventory. The Western Revolving Credit Facility also provides for letters of credit and swing line loans and provides for a quarterly commitment fee ranging from 0.25% to 0.50% per annum subject to adjustment based upon the average utilization ratio and letter of credit fees ranging from 1.75% to 2.25% per annum, payable quarterly, subject to adjustment based upon the average excess availability. Borrowings can be either base rate loans plus a margin ranging from 0.75% to 1.25% or LIBOR loans plus a margin ranging from 1.75% to 2.25%, in each case subject to adjustment based upon the average excess availability under the Western Revolving Credit Facility. The majority of Western's restricted subsidiaries fully and unconditionally guarantee the Western Revolving Credit Facility on a joint and several basis. The Western Revolving Credit Facility is secured by our cash and cash equivalents, accounts receivable and inventory.
	As of June 30, 2014, we had no direct borrowings under the Revolving Credit Agreement, with gross availability of $851.4 million, of which $164.2 million was used for outstanding letters of credit.
	Term Loan Credit Agreement
	On November 12, 2013, we entered into a term loan credit agreement (the "Western 2020 Term Loan Credit Facility"). The Western 2020 Term Loan Credit Facility provides for loans of $550.0 million, matures on November 12, 2020 and provides for quarterly principal payments of $1.4 million until September 30, 2020, with the remaining balance then outstanding due on the maturity date. The Western 2020 Term Loan Credit Facility bears interest at a rate based either on the base rate (as defined in the Western 2020 Term Loan Credit Facility) plus 2.25% or the Eurodollar Rate (as defined in the Western 2020 Term Loan Credit Facility) plus 3.25% (with a Euro dollar rate floor of 1.00%). The Western 2020 Term Loan Credit Facility is secured by both the El Paso and Gallup refineries and is fully and unconditionally guaranteed on a joint and several basis by substantially all of Western's material subsidiaries.
	11.25% Senior Secured Notes
	During the first and second quarters of 2013, we redeemed or otherwise purchased and canceled all outstanding Western Senior Secured Notes for $349.4 million, including $24.4 million in redemption fees, resulting in a loss on extinguishment of debt of $46.7 million including the write-off of $4.2 million of unamortized loan fees.
	6.25% Senior Unsecured Notes
	On March 25, 2013, we entered into an indenture (the "Western 2021 Indenture") for the issuance of $350.0 million in aggregate principal amount of 6.25% Senior Unsecured Notes due 2021 (the "Western 2021 Senior Unsecured Notes"). The Western 2021 Senior Unsecured Notes are guaranteed on a senior unsecured basis by each of our wholly-owned domestic restricted subsidiaries. We pay interest on the Western 2021 Senior Unsecured Notes semi-annually in arrears on April 1 and October 1 of each year. The Western 2021 Senior Unsecured Notes mature on April 1, 2021.
	5.75% Convertible Senior Unsecured Notes
	On March 7, 2014, we provided notice to the Trustee and the holders (the “Noteholders”) of our 5.75% Convertible Senior Unsecured Notes (the "Western Convertible Notes") informing the Trustee and the Noteholders of our election, with respect to all conversions requested by Noteholders in accordance with the terms of the Indenture received by the conversion agent on or after March 20, 2014, to settle conversions of the Western Convertible Notes through the issuance of shares of our common stock. On various dates between March 26, 2014, and June 2, 2014, we delivered an aggregate of 9,155 shares of common stock to Noteholders to satisfy the conversion of $87,000 aggregate principal amount of Western Convertible Notes based on conversion rates, dependent on conversion date, of 105.2394 or 105.8731 shares of common stock for each $1,000 of principal amount of Western Convertible Notes converted. On June 16, 2014, we delivered 22,750,088 shares of common stock to Noteholders, to satisfy the conversion of $214,881,000 aggregate principal amount of Western Convertible Notes, based on a conversion rate of 105.8731 shares of common stock for each $1,000 of principal amount of Western Convertible Notes converted.
	In addition to these conversions, we paid cash for the remainder of the outstanding amount of the Western Convertible Notes with a nominal loss on extinguishment of debt.
	WNRL Obligations
	Revolving Credit Facility
	On October 16, 2013, WNRL entered into a $300.0 million senior secured revolving credit facility ("WNRL Revolving Credit Facility"). WNRL has the ability to increase the total commitment of the revolving credit facility by up to $200.0 million for a total facility size of up to $500.0 million, subject to certain conditions. The WNRL Revolving Credit Facility includes a $25.0 million sub-limit for standby letters of credit and a $10.0 million sub-limit for swing line loans. Obligations under the WNRL Revolving Credit Facility and certain cash management and hedging obligations are guaranteed by all of WNRL's subsidiaries. Obligations under the WNRL Revolving Credit Facility are secured by a first priority lien on substantially all of WNRL's and its subsidiaries' significant assets. WNRL creditors under the WNRL Revolving Credit Facility have no recourse to Western's assets, except to the extent of the assets of Western Refining Logistic GP, LLC, the general partner of WNRL that Western wholly owns. The WNRL Revolving Credit Facility will mature on October 16, 2018. Borrowings under the WNRL Revolving Credit Facility bear interest at either a base rate plus an applicable margin ranging from 0.75% to 1.75%, or at LIBOR plus an applicable margin ranging from 1.75% to 2.75%. The applicable margin will vary based upon WNRL's Consolidated Total Leverage Ratio, as defined in the WNRL Revolving Credit Facility. WNRL had no direct or swing line borrowings or outstanding letters of credit under the revolving credit facility as of June 30, 2014.
	The WNRL Credit Facility contains covenants that limit or restrict WNRL's ability to make cash distributions. WNRL is required to maintain certain financial ratios that are tested on a quarterly basis for the immediately preceding four quarter period.
	NTI Obligations
	NTI’s creditors have no recourse to Western or WNRL assets. Western or WNRL creditors have no recourse to the assets of NTI or its consolidated subsidiaries.
	Revolving Credit Facility
	On July 17, 2012, NTI amended its $300.0 million senior secured Revolving Credit Facility, (the "NTI Revolving Credit Facility"). The NTI Revolving Credit Facility, which matures on July 17, 2017, provides for up to $150.0 million for the issuance of letters of credit and up to $30.0 million for short-term borrowings. The NTI Revolving Credit Facility may be increased up to a maximum aggregate principal amount of $450.0 million, subject to borrowing base availability. Obligations under the NTI Revolving Credit Facility are secured by substantially all of NTI’s assets. Indebtedness under the NTI Revolving Credit Facility is recourse to Northern Tier Energy GP LLC, its general partner, and is guaranteed by NTI and certain of its subsidiaries. Borrowings under the NTI Revolving Credit Facility bear interest at either (a) an alternative base rate plus an applicable margin (ranging between 1.00% and 1.50%) or (b) a LIBOR rate plus an applicable margin (ranging between 2.00% and 2.50%). The alternative base rate is the greater of (a) the prime rate, (b) the Federal Funds Effective Rate plus 50 basis points or (c) the one-month LIBOR rate plus 100 basis points and a spread of up to 150 basis points based upon percentage utilization of this facility. In addition to paying interest on outstanding borrowings, NTI is also required to pay an annual commitment fee ranging from 0.375% to 0.500% and letter of credit fees.
	As of June 30, 2014, the availability under the NTI Revolving Credit Facility was $244.0 million. This availability is net of $35.2 million in outstanding letters of credit. NTI had no borrowings under the NTI Revolving Credit Facility at June 30, 2014.
	7.125% Secured Notes
	On November 8, 2012, Northern Tier Energy LLC, its wholly owned subsidiary ("NTI LLC"), and Northern Tier Finance Corporation (together with NTI LLC, the "NTI 2020 Notes Issuers"), issued $275.0 million in aggregate principal amount of 7.125% senior secured notes due 2020 (the "NTI 2020 Secured Notes"). The obligations under the NTI 2020 Secured Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by Northern Tier Energy LP and on a senior secured basis by (i) all of NTI LLC’s restricted subsidiaries that borrow, or guarantee obligations, under the NTI Revolving Credit Facility or any other indebtedness of NTI LLC or another subsidiary of NTI LLC that guarantees the NTI 2020 Secured Notes and (ii) all other material wholly owned domestic subsidiaries of NTI LLC.
The indenture governing the NTI 2020 Secured Notes contains covenants that limit or restrict dividends or other payments from restricted subsidiaries.
Indebtedness under the NTI 2020 Secured Notes is recourse to Northern Tier Energy GP LLC, its general partner, and is guaranteed by NTI and certain of their subsidiaries.

	Since 2012, our board of directors has approved three separate share repurchase programs authorizing us to repurchase up to $200 million, per program, of our outstanding common stock. Our board of directors approved our current share repurchase program in January of 2014 (the "January 2014 Program"). The January 2014 Program will expire on January 28, 2015, and through August 1, 2014, we have used $61.5 million of the authorized amount. Since the inception of the initial share repurchase program in July 2012 through June 30, 2014, we purchased 11.9 million shares of our common stock under the programs. Between March 26, 2014, and June 16, 2014, in connection with the settlement of conversions of the Western Convertible Notes, we utilized 12.1 million shares of treasury stock, consisting of treasury shares acquired prior to the three share repurchase programs and shares purchased under the programs through June 10, 2014, to satisfy a portion of these conversions.
	Subject to market conditions as well as corporate, regulatory and other considerations, we will repurchase shares from time-to-time through open market transactions, block trades, privately negotiated transactions or otherwise. Our board of directors may discontinue the share repurchase program at any time.
	The following table summarizes our share repurchase activity for the January 2014 Program:

	11. Income Taxes
	Compared to the federal statutory rate of 35%, our effective tax rates for the three and six months ended June 30, 2014, were 32.9% and 30.9%, respectively. The effective tax rates for the three and six months ended June 30, 2014, were lower than the statutory rate primarily due to the reduction of taxable income associated with the non-controlling interests in WNRL and NTI. Compared to the federal statutory rate of 35%, our effective tax rates for the three and six months ended June 30, 2013, were 35.7% and 36.0%, respectively, primarily due to state tax obligations offset by the Domestic Production Activity Deduction.
	The Internal Revenue Service (the "IRS") has finalized an examination of our tax year ending December 31, 2011, with no material adjustments. The IRS has completed examinations of our tax years ending December 31, 2010, 2009, 2008 and 2007. For these years, we have agreed to all IRS adjustments. Due to statutory requirements, the tax years ending December 31, 2007 and 2008 require a review by the U.S. Joint Committee of Taxation prior to finalizing the audits. We do not believe the results of any of these examinations will have a material effect on our financial position, results of operations or cash flows, but the timing and the results of final determinations on these matters remains uncertain.
	We believe that it is more likely than not that the benefit from certain state net operating loss ("NOL") carryforwards related to the Yorktown refinery will not be realized. Accordingly, a valuation allowance of $23.7 million was provided against the deferred tax assets relating to these NOL carryforwards at June 30, 2014. There was no change in the valuation allowance for the Yorktown NOL carryforwards from December 31, 2013.
	As of June 30, 2014, we have recorded a liability of $10.1 million for unrecognized tax benefits, of which $10.1 million would affect our effective tax rate if recognized. We recognized $0.1 million and $0.2 million in interest and penalties for the three and six months ended June 30, 2014, respectively.

Crude Oil and Refined Product Risk Management	'
	13. Crude Oil and Refined Product Risk Management
	We enter into crude oil forward contracts to facilitate the supply of crude oil to the refineries. During the six months ended June 30, 2014, we entered into net forward, fixed-price contracts to physically receive and deliver crude oil that qualify as normal purchases and normal sales and are exempt from derivative reporting requirements.
	We also use crude oil and refined products futures, swap contracts or options to mitigate the change in value for a portion of our LIFO inventory volumes subject to market price fluctuations and swap contracts to fix the margin on a portion of our future gasoline and distillate production. The physical volumes are not exchanged; these contracts are net settled with cash. For instruments used to mitigate the change in value of volumes subject to market prices, we elected not to pursue hedge accounting treatment for financial accounting purposes. The swap contracts used to fix the margin on a portion of our future gasoline and distillate production do not qualify for hedge accounting treatment.
	The fair value of these contracts is reflected in the Condensed Consolidated Balance Sheets and the related net gain or loss is recorded within cost of products sold 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 of the majority of the contracts for the purpose of marking to market the hedging instruments at each period end.
	The following tables summarize our economic hedging activity recognized within cost of products sold for the three and six months ended June 30, 2014 and 2013 and open commodity hedging positions as of June 30, 2014, and December 31, 2013:

	Offsetting Assets and Liabilities
	Western's derivative financial instruments are subject to master netting arrangements to manage counterparty credit risk associated with derivatives; however, Western does not offset the fair value amounts recorded for derivative instruments under these agreements in the Condensed Consolidated Balance Sheets. We have posted margin collateral with various counterparties to support hedging and trading activities. The margin collateral posted is required by counterparties as collateral deposits and cannot be offset against the fair value of open contracts except in the event of default.
	The following table presents offsetting information regarding Western's derivative instruments as of June 30, 2014, and December 31, 2013:

	Our commodity hedging activities are initiated within guidelines established by management and approved by our board of directors. Due to mark-to-market accounting during the term of the various commodity hedging contracts, significant unrealized, non-cash net gains and losses could be recorded in our results of operations. Additionally, we may be required to collateralize any mark-to-market losses on outstanding commodity hedging contracts.
	As of June 30, 2014, we had the following outstanding crude oil and refined product hedging instruments that were entered into as economic hedges. Settlement prices for our unleaded gasoline crack spread swaps were an average of $18.90 per contract. Settlement prices for our distillate crack spread swaps range from $26.28 to $28.74 per contract.

	Western Refining Logistics, LP 2013 Long-Term Incentive Plan
	The Western Refining Logistics, LP 2013 Long-Term Incentive Plan (the "WNRL LTIP") was adopted by the Western Refining GP, LLC board of directors in connection with the completion of its initial public offering. The WNRL LTIP provides for grants of phantom units and distribution equivalent rights ("DERs"). As of June 30, 2014, there were 4.3 million phantom units reserved for future grants under the WNRL LTIP.
	The fair value of the phantom units is determined based on the closing price of WNRL common units on the grant date. The estimated fair value of the phantom units is amortized on a straight-line basis over the scheduled vesting periods of individual awards. WNRL incurred unit-based compensation expense of $0.4 million and $0.6 million for the three and six months ended June 30, 2014, respectively.
	The fair value at grant date of non-vested phantom units outstanding as of June 30, 2014, was $7.0 million. Total unrecognized compensation cost related to our non-vested phantom units totaled $6.3 million as of June 30, 2014, that is expected to be recognized over a weighted-average period of approximately 4.70 years.
	A summary of WNRL's unit award activity for the three and six months ended June 30, 2014 is set forth below:

	15. Earnings per Share
	We follow the provisions related to the accounting treatment of certain participating securities for the purpose of determining earnings per share. These provisions address share-based payment awards that have not vested and that contain nonforfeitable rights to dividend equivalents and state that they are participating securities and should be included in the computation of earnings per share pursuant to the two-class method. As discussed in Note 14, Stock-Based Compensation, we granted shares of restricted stock to certain employees and outside directors. Although ownership of these shares did not transfer to the recipients until the shares vested, recipients had voting and nonforfeitable dividend rights on these shares from the date of grant. Accordingly, we utilize the two-class method to determine our earnings per share. The final vesting for remaining restricted stock awards occurred during the first quarter of 2014.
	Diluted earnings per common share includes the effects of potentially dilutive shares that consist of unvested restricted share units. These awards are non-participating securities due to the forfeitable nature of their associated dividend equivalent rights, prior to vesting, and we do not consider the restricted share units in the two-class method when calculating earnings per share.
	The computation of basic and diluted earnings per share under the two-class method is presented as follows:

	Weighted average number of diluted shares outstanding	102,657			104,729			102,655			106,942
	A shareholder's interest in our common stock could become diluted as a result of vestings of restricted share units and prior to the redemption of the Western Convertible Notes during the second quarter of 2014 (see Note 9, Long-Term Debt for further discussion) into actual shares of our common stock. In calculating our fully diluted earnings per common share, we consider the impact of restricted share units that have not vested and common equivalent shares related to the Western Convertible Notes. We include unvested restricted share units in our diluted earnings calculation when the trading price of our common stock equals or exceeds the per share or per share unit grant price. Common equivalent shares from the Western Convertible Notes are generally included in our diluted earnings calculation when net income exceeds certain thresholds above which the effect of the shares becomes dilutive. The Western Convertible Notes were converted into actual shares of our common stock during the first six months of 2014.
	The table below summarizes our 2014 cash dividend declarations, payments and scheduled payments through August 1, 2014:

	Total											$	41,475
	(1) The third quarter 2014 cash dividend of $0.26 per common share will result in an aggregate payment of $26.3 million.
	Total dividends declared were $0.26, $0.52, $0.12 and $0.24 per common share, including those declared related to participating securities, for the three and six months ended June 30, 2014 and 2013, respectively.

Leases [Abstract]	'
Commitments Disclosure [Text Block]	'
	17. Commitments
	We have commitments under various operating leases with initial terms greater than one year for retail convenience stores, office space, warehouses, card locks, railcars and other facilities. These leases have terms that will expire on various dates through 2036. We expect that in the normal course of business, these leases will be renewed or replaced by other leases. Certain of our lease agreements provide for the fair value purchase of the leased asset at the end of the lease. Rent expense for operating leases that provide for periodic rent escalations or rent holidays over the term of the lease is recognized on a straight-line basis.
	In the normal course of business, we also have long-term commitments to purchase services, such as natural gas, electricity, water and transportation services for use by our refineries and logistic assets at market-based rates. We are also party to various refined product and crude oil supply and exchange agreements.
	Under a sulfuric acid regeneration and sulfur gas processing agreement with E.I. du Pont de Nemours ("DuPont"), DuPont constructed and operates two sulfuric acid regeneration plants on property we lease to DuPont within our El Paso refinery.
	In November 2007, our subsidiary entered into a ten-year lease agreement for an office space in downtown El Paso, Texas. The building serves as our headquarters. In December 2007, our subsidiary entered into an eleven-year lease agreement for an office building in Tempe, Arizona. The building centralized our operational and administrative offices in the Phoenix, Arizona area.
	We are party to nineteen capital leases, with initial terms of 20 years, expiring in 2017 through 2033. The current portion of our capital lease obligations of $0.6 million and $0.6 million is included in accrued liabilities and the non-current portion of $24.6 million and $24.9 million is included in lease financing obligations in the accompanying Condensed Consolidated Balance Sheets as of June 30, 2014, and December 31, 2013, respectively. These capital leases were discounted using annual interest rates of 3.24% to 10.51%. Total remaining interest related to these leases was $19.3 million and $20.1 million at June 30, 2014, and December 31, 2013, respectively. Annual payments net of interest average $2.3 million through the end of 2018 with the remaining $28.8 million due through 2033. Of the nineteen capital leases, twelve are NTI obligations with annual lease payments net of interest that average $0.9 million annually through the end of 2018 with the remaining $7.2 million due through 2033. There is no recourse to Western on the NTI capital leases.
	The following table presents our annual minimum rental payments under non-cancelable operating leases that have lease terms of one year or more (in thousands) as of June 30, 2014:
	Remaining 2014	$	25,495

	18. Contingencies
	Environmental Matters
	Similar to other petroleum refiners, our operations are subject to extensive and periodically changing federal and state environmental regulations governing air emissions, wastewater discharges and solid and hazardous waste management activities. Many of these regulations are becoming increasingly stringent and the cost of compliance can be expected to increase over time. Our policy is to accrue environmental and clean-up related costs of a non-capital nature when it is probable that a liability has been incurred and the amount can be reasonably estimated. Such estimates may be subject to revision in the future as regulations and other conditions change.
	Periodically, we receive communications from various federal, state and local governmental authorities asserting violations of environmental laws and/or regulations. These governmental entities may also propose or assess fines or require corrective action for these asserted violations. We intend to respond in a timely manner to all such communications and to take appropriate corrective action. We do not anticipate that any such matters currently asserted will have a material impact on our financial condition, results of operations or cash flows.
	El Paso Refinery
	Prior spills, releases and discharges of petroleum or hazardous substances have impacted the groundwater and certain solid waste management units and other areas at and adjacent to our El Paso refinery. We are currently remediating, in conjunction with Chevron U.S.A., Inc. ("Chevron"), these areas in accordance with certain agreed administrative orders with the Texas Commission on Environmental Quality (the "TCEQ"; previously known as the Texas Natural Resources Conservation Commission). Pursuant to our purchase of the north side of the El Paso refinery from Chevron, Chevron retained responsibility to remediate its solid waste management units in accordance with its Resource Conservation Recovery Act ("RCRA") permit that Chevron has fulfilled. Chevron also retained control of and liability for certain groundwater remediation responsibilities that are ongoing.
	In May 2000, we entered into an Agreed Order with the TCEQ for remediation of the south side of our El Paso refinery property. We purchased a non-cancelable Pollution and Legal Liability and Clean-Up Cost Cap Insurance policy that covers environmental clean-up costs related to contamination that occurred prior to December 31, 1999, including the costs of the Agreed Order activities. The insurance provider assumed responsibility for all environmental clean-up costs related to the Agreed Order up to $20.0 million. In addition, a subsidiary of Chevron is obligated under a settlement agreement to pay 60% of any Agreed Order environmental clean-up costs that exceed the $20.0 million policy coverage.
	On June 30, 2011, the U.S. Environmental Protection Agency (the "EPA") filed notice with the federal district court in El Paso that we and the EPA entered into a proposed Consent Decree under the Petroleum Refinery Enforcement Initiative ("EPA Initiative"). On September 2, 2011, the court entered the Consent Decree. Under the EPA Initiative, the EPA is investigating industry-wide non-compliance with certain Clean Air Act rules. The EPA Initiative has resulted in many refiners entering into similar consent decrees typically requiring penalties and substantial capital expenditures for additional air pollution control equipment. The Consent Decree does not require any soil or groundwater remediation or clean-up.
	We have completed our capital expenditures to address the Consent Decree issues totaling $43.2 million, including $15.2 million for the installation of a flare gas recovery system completed in 2007 and $28.0 million for nitrogen oxides ("NOx") emission controls on heaters and boilers completed in 2013. Under the terms of the Consent Decree, we paid a civil penalty of $1.5 million in September 2011.
	In 2004 and 2005, our El Paso refinery applied for and was issued a Texas Flexible Permit by the TCEQ. In December 2012, we received a permit amendment obtaining a State Implementation Plan approved state air quality permit to address concerns raised by the EPA about all flexible permits. No additional capital expenditures are required by the permit amendment.
	In April 2014, we entered two Agreed Orders with TCEQ to settle unresolved air enforcement issued to our El Paso refinery between 2004 and April 2008. We completed payment of $0.2 million in penalties in May 2014 that included funding a Supplemental Environmental Project benefiting El Paso County. The orders do not require any soil or groundwater remediation or clean-up or capital expenditures.
	Four Corners Refineries
	Four Corners 2005 Consent Agreements. In July 2005, as part of the EPA Initiative, Giant Industries, Inc., our wholly-owned subsidiary, reached an administrative settlement with the New Mexico Environment Department (the "NMED") and the EPA in the form of consent agreements that resolved certain alleged violations of air quality regulations at the Gallup and Bloomfield refineries in the Four Corners area of New Mexico. In January 2009 and June 2012, we and the NMED agreed to amendments of the 2005 administrative settlement (the "2005 NMED Amended Agreement") that altered certain deadlines and allowed for alternative air pollution controls.
	We incurred $50.8 million in total capital expenditures between 2009 and 2013 to address the requirements of the 2005 NMED Amended Agreement. These capital expenditures were primarily for installation of emission controls on the heaters, boilers and FCCU and for reducing sulfur in fuel gas to reduce emissions of sulfur dioxide, NOx and particulate matter from our Gallup refinery. We will incur additional capital expenditures to implement one or more FCCU off-set projects to be completed by the end of 2017. We paid penalties between 2009 and 2012 totaling $2.7 million. Implementation of the requirements in the 2005 NMED Amended Agreement will not result in any soil or groundwater remediation or clean-up costs.
	Bloomfield 2007 NMED Remediation Order. In July 2007, we received a final administrative compliance order from the NMED alleging that releases of contaminants and hazardous substances that have occurred at the Bloomfield refinery over the course of its operation prior to June 1, 2007, have resulted in soil and groundwater contamination. Among other things, the order requires that we investigate the extent of such releases, perform interim remediation measures and implement corrective measures. Prior to July 2007, with the approval of the NMED and the New Mexico Oil Conservation Division, we placed into operation certain remediation measures that remain operational. As of June 30, 2014, we have expended $3.7 million and have accrued the remaining estimated costs of $3.6 million for implementing the investigation, interim measures and the reasonably known corrective actions of the order.
	Gallup 2007 Resource Conservation Recovery Act ("RCRA") Inspection. In September 2007, the Gallup refinery was inspected jointly by the EPA and the NMED to determine compliance with the EPA’s hazardous waste regulations promulgated pursuant to the RCRA. We reached a final settlement with the agencies in August 2009 and paid a penalty of $0.7 million in October 2009. Between September 2010 and July 2012, the EPA demanded and we paid penalties totaling $0.2 million in accordance with the settlement. Implementation of the requirements in the final settlement will not result in any additional soil or groundwater remediation or clean-up costs not otherwise required. We incurred a total of $38.6 million in capital expenditures between 2010 and 2013 to upgrade the wastewater treatment plant at the Gallup refinery in accordance with the requirements, and there are no further capital requirements, under the final settlement.
	Gallup 2013 Risk Management Plan General Duty Settlement. In July 2013, we entered a final settlement with the EPA for five alleged violations of the Clean Air Act Risk Management Plan 112(r) General Duty clause at our Gallup refinery and paid a total penalty of $0.2 million. No capital expenditures are required under the settlement.
	Gallup 2014 Environment Protection Division of NMED Settlement. In March 2014, we received a revised notice of violation and offer of settlement from the NMED Air Quality Bureau for alleged violations of the Clean Air Act. We agreed to settle and paid a penalty of $0.1 million in May, 2014. No capital expenditures are required under the settlement.
	NTI
	At June 30, 2014, and December 31, 2013, liabilities for remediation by NTI totaled $3.0 million and $1.5 million, respectively. These liabilities are expected to be settled over at least the next 25 years. Receivables for recoverable costs from the state, under programs to assist companies in clean-up efforts related to underground storage tanks at retail marketing outlets and others were $0.1 million at June 30, 2014, and December 31, 2013, respectively.
	On June 3, 2014, NTI was issued a National Pollutant Discharge Elimination Permit/State Disposal System Permit by the Minnesota Pollution Control Agency relating to its upgraded waste water treatment plant at its St. Paul Park refinery. This permit requires NTI to conduct additional testing of its remaining lagoon. NTI is currently planning to perform this testing as soon as water table conditions permit. Following this testing, NTI may be required to incur future remediation costs and/or capital spending, relating to this lagoon and associated fire water resources, some of which may be recoverable from Marathon Petroleum Company LP ("Marathon") under an agreement entered into in connection with NTI's December 2010 acquisition of the St. Paul Park refinery, among other assets, from Marathon.
	Yorktown Refinery
	Yorktown 1991 and 2006 Orders. In December 2011, our subsidiaries sold the Yorktown refinery, an adjacent parcel of land and all other related real estate and assets. As part of this transaction, the purchaser agreed to assume all obligations and remaining work required by the EPA under the 2006 soil and groundwater remediation order. The purchaser agreed to indemnify us for costs associated with the EPA order, following the sale, with the exception of the completion and related liability for construction of the second phase of the Corrective Action Measures Unit (the "CAMU"). We have completed construction of this phase of the CAMU and received EPA acceptance in August 2013. We and the purchaser agreed that the purchaser would replace Giant as the respondent under the EPA order. The replacement is pending the EPA's agreement.
	Other Matters
	The EPA has issued Renewable Fuels Standards ("RFS"), that require us and other refiners to blend renewable fuels into the refined products produced at our refineries. Annually, the EPA is required to establish a volume of renewable fuels that refineries must blend into their refined petroleum fuels. However, the EPA has not established the final renewable blending volume level for 2014. To the extent we are unable to blend at the rate necessary to satisfy the EPA mandated volume, we purchase Renewable Identification Numbers ("RIN"). The purchase price for RINs is volatile and may vary significantly from period to period. Historically, the cost of purchased RINs has not had a significant impact on our operating results. We anticipate 2014 will be consistent with this history.
	The EPA has initiated various enforcement proceedings against companies it believes produced invalid RINs and we understand the EPA continues to investigate invalid RINs. We routinely purchase RINs to satisfy a portion of our obligation under the RFS program and may have purchased RINs the EPA will consider invalid. We entered into a settlement with the EPA in 2012 and 2014 for previously purchased invalid RINs and are completing penalty payments totaling less than $0.1 million in the third quarter of 2014. While we do not know if the EPA will identify other RINs we have purchased as being invalid or what actions the EPA would take, at this time we do not expect any such action would have a material effect on our financial condition, results of operations or cash flows.
	We are party to various other claims and legal actions arising in the normal course of business. We believe that the resolution of these matters will not have a material effect on our financial condition, results of operations or cash flows.

Condensed Financial Statements [Text Block]	'
	20. Condensed Consolidating Financial Information
	Separate condensed consolidating financial information of Western Refining, Inc. (the "Parent") and subsidiary guarantors and non-guarantors are presented below. At June 30, 2014, the Parent and certain subsidiary guarantors have fully and unconditionally guaranteed our Western 2021 Unsecured Notes on a joint and several basis. As a result of these guarantee arrangements, we are required to present the following condensed consolidating financial information that should be read in conjunction with the accompanying consolidated financial statements and notes thereto.
	WNRL, NTI and Navajo Convenient Stores Co., LLC ("Navajo") are subsidiaries that have not guaranteed our Unsecured Notes. WNRL was not a subsidiary of the Parent during the six months ended June 30, 2013, because Western formed the entity in the fourth quarter of 2013. Additionally, NTI was not a subsidiary of the Parent during the six months ended June 30, 2013 because it was purchased on November 12, 2013. Separate condensed financial statements for Navajo were not disclosed in prior years because Navajo was considered a minor subsidiary and is not material to the consolidated financial statements in any period presented. Therefore, no financial information is presented for non-guarantors in the condensed consolidating financial statements for the six months ended June 30, 2013.
	WNRL and NTI are publicly held master limited partnerships. As of June 30, 2014, we owned a 65.3% limited partnership interest in WNRL and a 38.7% limited partnership interest in NTI and the non-financial general partner interests of both entities. We are the primary beneficiary of WNRL's earnings and cash flows. We exercise control of both WNRL and NTI through our 100% ownership of the respective general partners. Accordingly, WNRL and NTI are consolidated with the other accounts of Western.
	Our transactions with WNRL including fees paid under our pipeline, terminalling and services agreements with WNRL are eliminated and have no significant impact on our consolidated financial statements. During the six months ended June 30, 2014, there have been no significant intercompany accounts or transactions between Western and NTI. All intercompany accounts and transactions with WNRL and NTI are eliminated in our consolidated financial statements.
	Western is WNRL’s primary customer. WNRL generates revenues by charging fees and tariffs for transporting crude oil through its pipelines and refined and other products through its terminals and pipelines and for providing storage in its storage tanks and at its terminals. Under our long-term pipeline and terminalling agreements with WNRL (see Note 21, Western Refining Logistics, LP), we accounted for 98.1% and 98.0% of WNRL’s total revenues for the three and six months ended June 30, 2014, respectively. We do not provide financial or equity support through any liquidity arrangements and/or debt guarantees to WNRL.
	WNRL has a senior secured revolving credit agreement. WNRL creditors under the revolving credit agreement have no recourse to our assets, except to the extent of the assets of Western Refining Logistic GP, LLC, the general partner of WNRL that we wholly own. Any recourse to WNRL’s general partner would be limited to the extent of the general partner’s assets that other than its investment in WNRL are not significant. Furthermore, our creditors have no recourse to the assets of WNRL's general partner, WNRL and its consolidated subsidiaries. See Note 9, Long-Term Debt, for a description of WNRL’s debt obligations.
	NTI has 7.125% Secured Notes and a secured ABL facility. NTI creditors under the 7.125% Secured Notes and secured ABL facility should have no recourse to the Parent's assets except to the extent of the assets of Northern Tier Energy GP LLC, the general partner of NTI that we wholly own. Any recourse to NTI’s general partner would be limited to the extent of the general partner’s assets that other than its investment in NTI are not significant. Furthermore, the Parent's creditors have no recourse to the assets of NTI's general partner, NTI and its consolidated subsidiaries. See Note 9, Long-Term Debt, for a description of NTI’s debt obligations.
	WNRL and NTI have risks associated with their respective operations. WNRL’s risks are directly associated with our operations. NTI’s risks, while similar to ours because it experiences similar industry dynamics, are not associated with our operations. If we suffer significant decreases in our throughput or fail to meet desired shipping or throughput levels for an extended period of time, WNRL revenues would be reduced and WNRL could suffer substantial losses.
	In the event that WNRL or NTI incur a loss, our operating results will reflect WNRL’s or NTI’s loss, net of intercompany eliminations, to the extent of our ownership interests in WNRL and NTI at that point in time.
	We restated the Condensed Consolidating Balance Sheet as of December 31, 2013, to correct immaterial errors in the presentation of the non-guarantors' investment in NTI, the Parent’s and the Guarantor Subsidiaries' Investment in Subsidiaries and the Parent’s and the Guarantor Subsidiaries' Equity. We previously presented $775.0 million as investment in NTI in the Investment in Subsidiaries line item in the non-guarantor column of the Condensed Consolidating Balance Sheets as of December 31, 2013. We have reclassified this amount into the Equity - Western line item in the non-guarantor column. We have also corrected the Parent’s equity in the earnings of subsidiaries by changing the previously reported Investment in Subsidiaries and Equity - Western of $1,854.6 million and $383.5 million, respectively, to $3,237.3 million and $894.1 million, respectively, in the Parent column. We made similar changes in the Guarantor Subsidiaries column by changing previously reported amounts of $431.6 million and $3,052.3 million, respectively to $(92.8) million and $2,448.6 million, respectively. We adjusted all of these amounts in the eliminations column. These errors did not have an impact on the consolidated balance sheet as of December 31, 2013, and we believe these corrections are not material to our previously issued annual or interim consolidated financial statements.
	The following condensed consolidating financial information is provided as an alternative to providing separate financial statements for guarantor subsidiaries. Separate financial statements of Western’s subsidiary guarantors are not included because the guarantees are full and unconditional and these subsidiary guarantors are 100% owned and jointly and severally liable for the Parent’s outstanding debt. The information is presented using the equity method of accounting for investments in subsidiaries.

	21. Western Refining Logistics, LP
	WNRL is a publicly traded limited partnership that was formed to own, operate, develop and acquire logistics assets and logistics related businesses. WNRL's assets consist of pipeline and gathering assets and terminalling, transportation and storage assets in the Southwestern portion of the U.S., including approximately 300 miles of pipelines and approximately 7.9 million barrels of active storage capacity, as well as other assets. The majority of WNRL's assets are integral to the operations of Western's refineries located in El Paso, Texas and near Gallup, New Mexico.
	We held a 65.3% limited partner interest in WNRL at June 30, 2014, including a non-economic general partner interest. This interest includes 6,998,500 common partnership units and 22,811,000 subordinated partnership units. All intercompany transactions with WNRL are eliminated upon consolidation.
	WNRL generates revenue by charging fees for gathering, transporting and storing crude oil on their pipeline systems and for terminalling, transporting and storing crude oil and refined products at their terminals. We do not provide financial or equity support through any liquidity arrangements or financial guarantees to WNRL.
	WNRL provides us with various pipeline transportation, terminal distribution and storage services under long-term, fee‑based commercial agreements expiring in 2023. These agreements contain minimum volume commitments. Each agreement has fees that are indexed for inflation and provides us with options to renew for two additional five-year terms.
	In addition to commercial agreements, we are also party to an omnibus agreement with WNRL that among other things provides for reimbursement to us for various general and administrative services provided to WNRL. We are also party to an operational services agreement with WNRL, under which we are reimbursed for personnel services provided by Western in support of WNRL's operations of its pipelines, terminals and storage facilities.
	WNRL entered into a credit agreement that provides for a $300 million senior secured revolving credit facility, expiring October 16, 2018. The revolving credit facility will be available to fund working capital, acquisitions, distributions, capital expenditures and for other general partnership purposes. See Note 9, Long-Term Debt for additional disclosure.
	On January 31, 2014, the board of directors of WNRL's general partner declared a quarterly cash distribution of $0.2407 per unit for the prorated period of October 16, 2013, through December 31, 2013, and corresponds to the prorated minimum quarterly distribution of $0.2875 per unit. WNRL paid the distribution on February 24, 2014, to all unitholders of record on February 14, 2014. WNRL paid no distributions prior to this date.
	The table below summarizes WNRL's 2014 quarterly distribution declarations, payments and scheduled payments through August 25, 2014:

	22. Acquisitions
	On November 12, 2013, Western purchased all of NTH’s interests in NT InterHoldCo LLC, a wholly-owned subsidiary of NTH that holds all of the membership interests in NTI and 35,622,500 common units representing a 38.7% limited partner interest in NTI for a purchase price of $775 million. The purchase price, including transaction expenses, was funded by a $550 million term loan and $242 million in cash.
	NTI's assets are located in the Upper Great Plains region and include a refinery in St. Paul Park, Minnesota that has a 96,500 bpd refining capacity. Refining operations include crude oil fractionation, catalytic cracking, hydrotreating, reforming, alkylation, sulfur recovery and a hydrogen plant. The refinery processes predominately North Dakota and Canadian crude oils into products such as gasoline, diesel, jet fuel, kerosene, asphalt, propane, propylene and sulfur. The refined products are sold to markets primarily located in the Upper Great Plains of the United States. NTI also operates convenience stores under the SuperAmerica brand that are primarily located in Minnesota and Wisconsin and sell gasoline, merchandise and in some locations, diesel fuel.
	The allocation of the purchase price was based upon a preliminary valuation. Our estimates and assumptions are subject to change during the purchase price allocation period that will end in the third quarter of 2014. The preliminary allocation of the aggregate purchase price of NTI as of June 30, 2014, is summarized as follows (in thousands):
	Net working capital	$	95,937
	Property, plant and equipment	916,705
	Intangible assets	38,200
	Other assets	114,000
	Long-term debt	(278,438		)
	Other liabilities	(50,743		)
	Non-controlling interest	(1,357,704		)
	Fair value of net assets acquired	(522,043		)
	Goodwill	1,297,043
	Purchase price	$	775,000
	The consolidated statements of operations include the results of NTI’s operations for the three and six months ended June 30, 2014. The following unaudited pro forma information assumes that (i) the acquisition of NTI occurred on January 1, 2012; (ii) $550.0 million was borrowed to fund the NTI acquisition on January 1, 2012, resulting in increased financing costs of $5.7 million and $11.1 million for the three and six months ended June 30, 2013, respectively; (iii) $9.2 million and $17.8 million increased depreciation and amortization expense for the three and six months ended June 30, 2013, respectively, for the increased estimated fair values of assets acquired beginning January 1, 2012; and (iv) income tax expense increased as a result of the increased operating income offset by increased depreciation, amortization and interest expense of $5.1 million and $21.5 million for the three and six months ended June 30, 2013.

Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition
	Revenues for products, crude oil and feedstocks sold are recorded upon delivery of the products, crude oil or feedstocks to customers; the point at which title is transferred, the customer has the assumed risk of loss and when payment has been received or collection is reasonably assured. Transportation, shipping and handling costs incurred are included in cost of products sold. Excise and other taxes collected from customers and remitted to governmental authorities are not included in revenues.
Goodwill and Intangible Assets, Policy [Policy Text Block]	'
	Goodwill and Other Unamortizable Intangible Assets
	Goodwill represents the excess of the purchase price (cost) over the fair value of the net assets acquired and is carried at cost. We do not amortize goodwill for financial reporting purposes. We test goodwill for impairment at the reporting unit level. The reporting unit or units used to evaluate and measure goodwill for impairment are determined primarily from the manner in which the business is managed. Our policy is to test goodwill and other unamortizable intangible assets for impairment annually at June 30, or more frequently if indications of impairment exist.
	We conducted our annual goodwill and intangible asset valuation analysis as of June 30, 2014, noting no indications of impairment.
Cost of Sales, Policy [Policy Text Block]	'
	Cost Classifications
	Refining cost of products sold includes cost of crude oil, other feedstocks and blendstocks, the costs of purchased refined products, transportation and distribution costs and realized and unrealized gains and losses related to our commodity hedging activities. Wholesale cost of products sold includes the cost of fuel and lubricants, transportation and distribution costs and service parts and labor. Retail cost of products sold includes costs for motor fuels and for merchandise. Motor fuel cost of products sold represents net cost for purchased fuel. Net cost of purchased fuel excludes transportation and motor fuel taxes. Merchandise cost of products sold includes merchandise purchases, net of merchandise rebates and inventory shrinkage.
	Refining direct operating expenses include direct costs of labor, maintenance materials and services, chemicals and catalysts, natural gas, utilities and other direct operating expenses. Wholesale direct operating expenses include direct costs of labor, transportation expense, maintenance materials and services, utilities and other direct operating expenses. Retail direct operating expenses include direct costs of labor, maintenance materials and services, outside services, bank charges, rent expense, utilities and other direct operating expenses. WNRL operating and maintenance expenses include labor costs, maintenance materials and services, natural gas, additives, utilities, insurance expense, property taxes and other operating expenses. NTI's direct operating expenses include direct costs of labor, maintenance materials and services, outside services, bank charges, rent expense, chemicals and catalysts, natural gas, utilities and other direct operating expenses.
Maintenance Cost, Policy [Policy Text Block]	'
	Maintenance Turnaround Expense
	Refinery process units require periodic maintenance and repairs that are commonly referred to as "turnarounds." The required frequency of the maintenance varies by unit, but generally is every two to six years depending on the processing unit involved. Turnaround costs are expensed as incurred.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates
	The preparation of financial statements 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
