Description of the Business and Basis of Presentation | Description of the Business and Basis of Presentation Description of the Business— Our business consists of refining and marketing, retail and midstream services conducted primarily in the Midwest, Gulf Coast, East Coast, Northeast and Southeast regions of the United States, through subsidiaries, including Marathon Petroleum Company LP, Speedway LLC and its subsidiaries (“Speedway”) and MPLX LP and its subsidiaries (“MPLX”). See Note 9 for additional information about our operations. Basis of Presentation— All significant intercompany transactions and accounts have been eliminated. These interim consolidated financial statements are unaudited; however, in the opinion of our management, these statements reflect all adjustments necessary for a fair statement of the results for the periods reported. All such adjustments are of a normal, recurring nature unless otherwise disclosed. These interim consolidated financial statements, including the notes, have been prepared in accordance with the rules of the SEC applicable to interim period financial statements and do not include all of the information and disclosures required by U.S. GAAP for complete financial statements. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 . The results of operations for the three months ended March 31, 2016 are not necessarily indicative of the results to be expected for the full year. We completed a two-for-one stock split in June 2015. All historical share and per share data included in these consolidated financial statements has been retroactively restated on a post-split basis. In the first quarter of 2016, we revised our segment reporting of the operating results for our inland marine business and our investment in an ocean vessel joint venture, Crowley Ocean Partners LLC (“Crowley Ocean Partners”) in connection with the contribution of our inland marine business to MPLX. See Note 3 for additional information. These operating results are now reported in our Midstream segment. Previously they were reported as part of our Refining & Marketing segment. Comparable prior period information has been recast to reflect our revised segment presentation. See Note 9 for additional information. |

Accounting Changes and Error Corrections [Abstract] | |
Accounting Standards | Accounting Standards Recently Adopted In September 2015, the FASB issued an accounting standard update that eliminates the requirement to restate prior period financial statements for measurement period adjustments for business combinations. This update requires that the cumulative impact of a measurement period adjustment be recognized in the reporting period in which the adjustment is identified. The standard was effective for interim and annual periods beginning after December 15, 2015 with early application permitted. We recognized measurement period adjustments during the three months ended March 31, 2016 as additional analysis was completed on the preliminary purchase price allocation for the acquisition of MarkWest Energy Partners, L.P. (“MarkWest”). See Note 4 for further discussion and detail related to the adjustment. In May 2015, the FASB issued an accounting standard update that eliminates the requirement to categorize in the fair value hierarchy investments that are measured at net asset value using the practical expedient. The standard was effective for fiscal years beginning after December 15, 2015 and interim periods within the fiscal year. Retrospective application is required and early adoption is permitted. Adoption of this standard update in the first quarter of 2016 did not have a material impact on our disclosures. In April 2015, the FASB issued an accounting standard update clarifying whether a customer should account for a cloud computing arrangement as an acquisition of a software license or as a service arrangement by providing characteristics that a cloud computing arrangement must have in order to be accounted for as a software license acquisition. The change was effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. Retrospective or prospective application is allowed and early adoption is permitted. We adopted this standard prospectively in the first quarter of 2016 and it did not have a material impact on our consolidated results of operations, financial position or cash flows. In February 2015, the FASB issued an accounting standard update making targeted changes to the current consolidation guidance. The new standard changes the considerations related to substantive rights, related parties, and decision making fees when applying the VIE consolidation model and eliminates certain guidance for limited partnerships and similar entities under the voting interest consolidation model. The update was effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. Under the new standard, we continue to consolidate our master limited partnership, MPLX, but it is now considered to be a VIE. The standard update did impact our disclosures for this consolidated VIE, but did not have a material impact on our results of operations, financial position or cash flows. In June 2014, the FASB issued an accounting standard update for the elimination of the concept of development stage entity (“DSE”) from U.S. GAAP and removes the related incremental reporting. The standards update eliminates the additional financial statement requirements specific to a DSE and was adopted in the first quarter of 2015. In addition, the portion of the standard to amend the consolidation model that eliminates the special provisions in the VIE rules for assessing the sufficiency of the equity of a DSE was adopted in the first quarter of 2016. Adoption of this standards update in the first quarter of 2015 and 2016 did not have an impact on our consolidated results of operations, financial position or cash flows. Not Yet Adopted In March 2016, the FASB issued an accounting standard update to simplify some provisions in stock compensation accounting. The areas for simplification of this update involve the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification of the statement of cash flows. This update will be effective for annual reporting periods beginning after December 15, 2016, and interim periods within those years and early adoption is permitted. We do not expect application of this standard to have a material impact on our consolidated financial statements. In March 2016, the FASB issued an accounting standard update eliminating the requirement that an investor retrospectively apply equity method accounting when an investment that it had accounted for by another method initially qualifies for the equity method. This update will be effective for annual reporting periods beginning after December 15, 2016, and interim periods within those years. The guidance will be applied prospectively and early adoption is permitted. We do not expect application of this standard to have a material impact on our consolidated financial statements. In February 2016, the FASB issued an accounting standard update on lease accounting. This update requires lessees to record most leases on their balance sheets. The new standard also requires new disclosures to help financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The accounting standard update will be effective on a retrospective or modified retrospective basis for annual reporting periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. We are in the process of determining the impact of the new standard on the consolidated financial statements. In January 2016, the FASB issued an accounting standard update requiring unconsolidated equity investments, not accounted for under the equity method, to be measured at fair value with changes in fair value recognized in net income. The update also requires the use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes and the separate presentation of financial assets and liabilities by measurement category and form on the balance sheet and accompanying notes. The update eliminates the requirement to disclose the methods and assumptions used in estimating the fair value of financial instruments measured at amortized cost. Lastly, the update requires separate presentation in other comprehensive income of the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when electing to measure the liability at fair value in accordance with the fair value option for financial instruments. The changes are effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. Upon adoption, entities will be required to make a cumulative-effect adjustment to the consolidated results of operations as of the beginning of the first reporting period the guidance is effective. Early adoption is permitted only for the amendment regarding presentation of a liability’s credit risk. We do not expect application of this standard to have a material impact on our consolidated financial statements. In August 2014, the FASB issued an accounting standard update requiring management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. Management will be required to assess if there is substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Disclosures will be required if conditions give rise to substantial doubt and the type of disclosure will be determined based on whether management’s plans will be able to alleviate the substantial doubt. The accounting standard update will be effective for the first annual period ending after December 15, 2016, and for annual periods and interim periods thereafter with early application permitted. We do not expect application of this standard to have an impact on our financial reporting. In May 2014, the FASB issued an accounting standard update for revenue recognition. The guidance in the update states that revenue is recognized when a customer obtains control of a good or service. Recognition of the revenue will involve a multiple step approach including identifying the contract, identifying the separate performance obligations, determining the transaction price, allocating the price to the performance obligations and then recognizing the revenue as the obligations are satisfied. Additional disclosures will be required to provide adequate information to understand the nature, amount, timing and uncertainty of reported revenues and revenues expected to be recognized. The accounting standard update will be effective on a retrospective or modified retrospective basis for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted, no earlier than January 1, 2017. We are in the process of determining the impact of the new standard on our consolidated financial statements. |
MPLX LP
MPLX LP | 3 Months Ended |
Mar. 31, 2016 | |
Noncontrolling Interest [Abstract] | |
MPLX LP | MPLX LP MPLX is a publicly traded master limited partnership formed by us to own, operate, develop and acquire pipelines and other midstream assets related to the transportation and storage of hydrocarbon-based products, including crude oil, refined products, natural gas and NGLs. On December 4, 2015, MPLX and MarkWest completed a merger, whereby MarkWest became a wholly-owned subsidiary of MPLX (the “MarkWest Merger”). MarkWest’s operations include: natural gas gathering, processing and transportation; and NGL gathering, transportation, fractionation, storage and marketing. MPLX’s other assets include a 100 percent interest in MPLX Pipe Line Holdings LLC (“Pipe Line Holdings”), which owns a network of common carrier crude oil and product pipeline systems and associated storage assets in the Midwest and Gulf Coast regions of the United States and a 100 percent interest in a butane cavern in Neal, West Virginia. And effective March 31, 2016 (as described below), MPLX also owns an inland marine business, which is comprised of 18 tow boats and 205 barges and transports primarily crude oil and refined products in the Midwest and Gulf Coast regions of the United States principally for MPC. As of March 31, 2016 , we owned a 25 percent interest in MPLX, including a two percent general partner interest. MPLX is a VIE because the limited partners of MPLX do not have substantive kick-out or substantive participating rights over the general partner. We are the primary beneficiary of MPLX because in addition to significant economic interest, we also have the power, through our 100 percent ownership of the general partner interest, to control the decisions that most significantly impact MPLX. We therefore consolidate MPLX and record a noncontrolling interest for the 75 percent interest owned by the public. The creditors of MPLX do not have recourse to MPC’s general credit through guarantees or other financial arrangements. Contribution of Inland Marine Business to MPLX On March 31, 2016, we contributed our inland marine business to MPLX in exchange for 23 million MPLX common units and 460 thousand general partner units. The number of units we received from MPLX was determined by dividing $600 million by the volume weighted average NYSE price of MPLX common units for the 10 trading days preceding March 14, 2016, pursuant to the Membership Interests Contribution Agreement. We also agreed to waive first-quarter 2016 common unit distributions, IDRs and general partner distributions, with respect to the common units issued in this transaction. The contribution of our inland marine business was accounted for as a transaction between entities under common control and we did not record a gain or loss. ATM Program On March 4, 2016, MPLX filed a prospectus supplement to its shelf registration statement filed with the SEC on March 27, 2015, authorizing the continuous issuance of up to an aggregate of $500 million of common units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of any offerings (such continuous offering program, or at-the-market program, referred to as the “ATM Program”). MPLX expects to use the net proceeds from sales under the ATM Program for general partnership purposes. During the three months ended March 31, 2016 , MPLX issued an aggregate of 12 million common units under the ATM Program, generating net proceeds of approximately $315 million . As a result of common units issued under the ATM Program during the period, we contributed approximately $6 million to MPLX in exchange for general partner units to maintain our two percent general partner interest. Agreements We have various long-term, fee-based transportation and storage services agreements with MPLX. Under these agreements, MPLX provides transportation and storage services to us, and we commit to provide MPLX with minimum quarterly throughput volumes on crude oil and refined products systems and minimum storage volumes of crude oil, refined products and butane. We also have agreements with MPLX that establish fees for operational and management services provided between us and MPLX and for executive management services and certain general and administrative services provided by us to MPLX. These transactions are eliminated in consolidation. |

Acquisitions and Investments | Acquisition and Investments Merger with MarkWest Energy Partners, L.P. On December 4, 2015, MPLX completed the MarkWest Merger. The total value of consideration transferred was $8.61 billion , consisting of $7.33 billion in equity and $1.28 billion in cash. At closing, we made a payment of $1.23 billion to MarkWest common unitholders and the remaining $50 million will be paid in equal amounts in July 2016 and July 2017, respectively, in connection with the conversion of the MPLX Class B units to MPLX common units. Our financial results and operating statistics reflect the results of MarkWest from the date of the MarkWest Merger. The following table summarizes the preliminary purchase price allocation. Subsequent to December 31, 2015 , additional analysis was completed and adjustments were made to the preliminary purchase price allocation as noted in the table below. The estimated fair value of assets acquired and liabilities and noncontrolling interests assumed at the acquisition date as of March 31, 2016 , are as follows: (In millions) As originally reported Adjustments As adjusted Cash and cash equivalents $ 12 $ — $ 12 Receivables 164 — 164 Inventories 33 (1 ) 32 Other current assets 44 — 44 Equity method investments 2,457 143 2,600 Property, plant and equipment, net 8,474 43 8,517 Other noncurrent assets (a) 473 65 538 Total assets acquired 11,657 250 11,907 Accounts payable 322 6 328 Payroll and benefits payable 13 — 13 Accrued taxes 21 — 21 Other current liabilities 44 — 44 Long-term debt 4,567 — 4,567 Deferred income taxes 374 3 377 Deferred credit and other liabilities 151 — 151 Noncontrolling interests 13 — 13 Total liabilities and noncontrolling interest assumed 5,505 9 5,514 Net assets acquired excluding goodwill 6,152 241 6,393 Goodwill 2,454 (241 ) 2,213 Net assets acquired $ 8,606 $ — $ 8,606 (a) The adjustment relates to the intangible asset acquired. Adjustments to the preliminary purchase price stem mainly from additional information obtained by management in the first quarter about facts and circumstances that existed at the acquisition date including updates to forecasted employee benefit costs and capital expenditures, and completion of certain valuations to determine the underlying fair value of certain acquired assets. The adjustment to intangibles mainly relates to a misstatement in the original preliminary purchase price allocation. The correction of the error resulted in a $68 million reduction to the carrying value of goodwill and an offsetting increase of $64 million in intangibles and $2 million in each of equity method investments and property, plant and equipment. Management concluded that the correction of the error is immaterial to the consolidated financial statements of all periods presented. We are still completing our analysis of the final purchase price allocation . The increase to fair value of equity method investments, property plant and equipment, and other noncurrent assets noted above would not have resulted in a material effect to depreciation and amortization or income from equity method investments in the Consolidated Statements of Income for the year ended December 31, 2015, had the fair value adjustments been recorded as of December 4, 2015. The net fair value of the assets acquired and liabilities assumed in connection with the MarkWest Merger was less than the fair value of the total consideration resulting in the recognition of $2.21 billion of goodwill in three reporting units within our Midstream segment, substantially all of which is not deductible for tax purposes. Goodwill represents the complementary aspects of the highly diverse asset base of MarkWest and MPLX that will provide significant additional opportunities across the hydrocarbon value chain. As further discussed in Note 14 , we recorded a goodwill impairment charge based on the implied fair value of goodwill as of the interim impairment analysis date. Therefore, any future adjustments to the purchase price allocation will be offset by adjustments to the impairment expense line item in the Consolidated Statements of Income. Unaudited Pro Forma Financial Information The following unaudited pro forma financial information presents consolidated results assuming the MarkWest Merger occurred on January 1, 2014. The unaudited pro forma financial information does not give effect to potential synergies that could result from the transaction and is not necessarily indicative of the results of future operations. Three Months Ended (In millions, except per share data) 2015 Sales and other operating revenues (including consumer excise taxes) $ 17,652 Net income attributable to MPC 871 Net income attributable to MPC per share – basic $ 1.60 Net income attributable to MPC per share – diluted 1.59 The unaudited pro forma information includes adjustments to align accounting policies, an adjustment to depreciation expense to reflect the fair value of property, plant and equipment, increased amortization expense related to identifiable intangible assets, adjustments to amortize the fair value adjustment for the debt assumed by MPLX, adjustments to reflect the change in our limited partner interest in MPLX resulting from the MarkWest Merger, as well as the related income tax effects. Investment in Ocean Vessel Joint Venture In September 2015, we acquired a 50 percent ownership interest in a new joint venture with Crowley Maritime Corporation through our investment in Crowley Ocean Partners. The joint venture will operate and charter four new Jones Act product tankers, most of which will be leased to MPC. The new vessels are in various stages of construction with two of them completed and operational prior to the end of the first quarter. Contributions to the joint venture with respect to each vessel will occur at the vessel’s delivery. During 2015, we contributed $72 million in connection with delivery of the first two vessels. The third vessel was delivered April 15, 2016 and the remaining vessel is expected to be delivered by the third quarter of 2016. We account for our ownership interest in Crowley Ocean Partners as an equity method investment. In the first quarter of 2016, we revised our internal reporting of operating results for our investment in Crowley Ocean Partners. These operating results are now reported in our Midstream segment. Previously they were reported as part of our Refining & Marketing segment. Prior periods have been recast to reflect our revised segment presentation. See Note 22 for information on our conditional guarantee of the indebtedness of the joint venture and future contributions to Crowley Ocean Partners. Investment in Pipeline Company In November 2013, we agreed to serve as an anchor shipper for the Sandpiper pipeline project and fund 37.5 percent of the construction costs of the project, which will become part of Enbridge Energy Partners L.P.’s (“Enbridge Energy Partners”) North Dakota System. In exchange for these commitments, we will earn an approximate 27 percent equity interest in Enbridge Energy Partners’ North Dakota System when the Sandpiper pipeline is placed into service. We also have the option to increase our ownership interest to approximately 30 percent through additional investments in future system improvements. The anticipated in-service date for the pipeline is likely to be delayed from 2017 to early 2019, which is also likely to increase cost estimates for the project. The project schedule and cost estimates remain under review. We made contributions of $5 million to North Dakota Pipeline Company LLC (“North Dakota Pipeline”) during the three months ended March 31, 2016 and have contributed $292 million since project inception. We account for our interest in North Dakota Pipeline as part of our Midstream segment using the equity method of accounting. See Note 22 for information on future contributions to North Dakota Pipeline. |

Earnings Per Share [Abstract] | |
Income per Common Share | Income per Common Share We compute basic earnings per share by dividing net income attributable to MPC by the weighted average number of shares of common stock outstanding. The average number of shares of common stock and per share amounts have been retroactively restated to reflect the two-for-one stock split completed in June 2015. Diluted income per share assumes exercise of certain stock-based compensation awards, provided the effect is not anti-dilutive. MPC grants certain incentive compensation awards to employees and non-employee directors that are considered to be participating securities. Due to the presence of participating securities, we have calculated our earnings per share using the two-class method.

Segment Reporting [Abstract] | |
Segment Information | Segment Information In the first quarter of 2016, we revised our segment reporting of the operating results for our inland marine business and our investment in Crowley Ocean Partners in connection with the contribution of our inland marine business to MPLX. These operating results are now reported in our Midstream segment. Previously they were reported as part of our Refining & Marketing segment. Comparable prior period information has been recast to reflect our revised segment presentation. We have three reportable segments: Refining & Marketing; Speedway; and Midstream. Each of these segments is organized and managed based upon the nature of the products and services it offers. • Refining & Marketing – refines crude oil and other feedstocks at our refineries in the Gulf Coast and Midwest regions of the United States, purchases ethanol and refined products for resale and distributes refined products through various means, including terminals and trucks that we own or operate. We sell refined products to wholesale marketing customers domestically and internationally, to buyers on the spot market, to our Speedway segment and to independent entrepreneurs who operate Marathon ® retail outlets. • Speedway – sells transportation fuels and convenience merchandise in retail markets in the Midwest, East Coast and Southeast regions of the United States. • Midstream – includes the operations of MPLX and certain other related operations. The Midstream segment gathers, processes and transports natural gas; gathers, transports, fractionates, stores and markets NGLs and transports and stores crude oil and refined products. On December 4, 2015, MPLX completed a merger with MarkWest and its results are included in the Midstream segment. Segment information for periods prior to the MarkWest Merger does not include amounts for these operations. See Note 4 . Segment income represents income from operations attributable to the reportable segments. Corporate administrative expenses and costs related to certain non-operating assets are not allocated to the reportable segments. In addition, certain items that affect comparability (as determined by the chief operating decision maker) are not allocated to the reportable segments.

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes The combined federal, state and foreign income tax rate was (17) percent and 35 percent for the three months ended March 31, 2016 and 2015 , respectively. The effective tax rate for the three months ended March 31, 2016 was significantly affected by permanent tax differences related to the net loss attributable to noncontrolling interest, including their proportional share of the goodwill impairment charge recorded by MPLX. The net loss attributable to noncontrolling interest reduced the effective rate by 51 percent from the U.S. statutory rate of 35 percent . For the three months ended March 31, 2015 , the effective tax rate is equivalent to the U.S. statutory rate of 35 percent primarily due to certain permanent benefit differences, including the domestic manufacturing deduction, partially offset by state and local tax expense. On March 31, 2016, we contributed our inland marine business to MPLX in exchange for MPLX common units representing limited partner interests and general partner units resulting in an increase in MPC’s controlling interest in MPLX. A decrease in MPC’s deferred tax liabilities of $42 million directly related to this change in ownership of the underlying assets of MPLX was recorded with an offsetting increase to additional paid-in capital. During the first quarter of 2016, MPC’s deferred tax liabilities increased $115 million for an out of period adjustment to update the preliminary tax effects recorded in 2015 related to the MarkWest Merger, which was recorded with an offsetting decrease to additional paid-in capital. The impact of the adjustment was not material to the Consolidated Balance Sheet as of December 31, 2015. We are continuously undergoing examination of our income tax returns, which have been completed for our U.S. federal and state income tax returns through the 2009 and 2003 tax years, respectively. We had $11 million of unrecognized tax benefits as of March 31, 2016 . Pursuant to our tax sharing agreement with Marathon Oil Corporation (“Marathon Oil”), the unrecognized tax benefits related to pre-spinoff operations for which Marathon Oil was the taxpayer remain the responsibility of Marathon Oil and we have indemnified Marathon Oil accordingly.

Costs of crude oil, refinery feedstocks and refined products are aggregated on a consolidated basis for purposes of assessing if the LIFO cost basis of these inventories may have to be written down to market values. The December 31, 2015 lower of cost or market reserve was reversed due to the sale of inventory quantities that gave rise to the 2015 reserve. A new lower of cost or market reserve of $385 million was established as of March 31, 2016 based on prices at that time. The effect of the change in lower of cost or market reserve was a $15 million charge to cost of revenues for the three months ended March 31, 2016 . Based on movements of refined product prices, future inventory valuation adjustments could have a negative or positive effect to earnings. Such losses are subject to reversal in subsequent periods if prices recover. The cost of inventories of crude oil and refinery feedstocks, refined products and merchandise is determined primarily under the LIFO method. There were no material liquidations of LIFO inventories for the three months ended March 31, 2016 and 2015 . |

Goodwill and Intangible Assets Disclosure [Abstract] | |
Goodwill | Goodwill is tested for impairment on an annual basis and when events or changes in circumstances indicate the fair value of a reporting unit with goodwill has been reduced below the carrying value of the net assets of the reporting unit. During the first quarter of 2016, MPLX, our consolidated subsidiary, determined that an interim impairment analysis of the goodwill recorded in connection with the MarkWest Merger was necessary based on consideration of a number of first quarter events and circumstances, including i) continued deterioration of near term commodity prices as well as longer term pricing trends, ii) recent guidance on reductions to forecasted capital spending, the slowing of drilling activity and the resulting reduced production growth forecasts released or communicated by MPLX’s producer customers and iii) increases in the cost of capital. The combination of these factors was considered to be a triggering event requiring an interim impairment test. Based on the first step of the interim goodwill impairment analysis, the fair value for the three reporting units to which goodwill was assigned in connection with the MarkWest Merger was less than their respective carrying value. In step two of the impairment analysis, the implied fair values of the goodwill were compared to the carrying values within those reporting units. Based on this assessment, it was determined that goodwill was impaired in two of the reporting units. Accordingly, MPLX recorded an impairment charge of approximately $129 million in the first quarter of 2016. The fair value of the reporting units for the interim goodwill impairment analysis was determined based on applying the discounted cash flow method, which is an income approach, and the guideline public company method, which is a market approach. The discounted cash flow fair value estimate is based on known or knowable information at the interim measurement date. The significant assumptions that were used to develop the estimates of the fair values under the discounted cash flow method include management’s best estimates of the expected future results and discount rates, which ranged from 10.5 percent to 11.5 percent . Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the interim goodwill impairment test will prove to be an accurate prediction of the future. The changes in the carrying amount of goodwill for the three months ended March 31, 2016 were as follows: (In millions) Refining & Marketing Speedway Midstream Total Balance at December 31, 2015 $ 539 $ 853 $ 2,627 $ 4,019 Purchase price allocation adjustments (a) — — (241 ) (241 ) Impairment — — (129 ) (129 ) Balance at March 31, 2016 $ 539 $ 853 $ 2,257 $ 3,649 (a) See Note 4 for further discussion on purchase price allocation adjustments. |

Fair Value Measurements | Fair Value Measurements Fair Values—Recurring The following tables present assets and liabilities accounted for at fair value on a recurring basis as of March 31, 2016 and December 31, 2015 by fair value hierarchy level. We have elected to offset the fair value amounts recognized for multiple derivative contracts executed with the same counterparty, including any related cash collateral as shown below; however, fair value amounts by hierarchy level are presented on a gross basis in the following tables. March 31, 2016 Fair Value Hierarchy (In millions) Level 1 Level 2 Level 3 Netting and Collateral (a) Net Carrying Value on Balance Sheet (b) Collateral Pledged Not Offset Commodity derivative instruments, assets $ 67 $ 1 $ 1 $ (67 ) $ 2 $ 72 Other assets 2 — — N/A 2 — Total assets at fair value $ 69 $ 1 $ 1 $ (67 ) $ 4 $ 72 Commodity derivative instruments, liabilities $ 107 $ — $ 1 $ (107 ) $ 1 $ — Embedded derivatives in commodity contracts (c) — — 34 — 34 — Contingent consideration, liability (d) — — 324 N/A 324 — Total liabilities at fair value $ 107 $ — $ 359 $ (107 ) $ 359 $ — December 31, 2015 Fair Value Hierarchy (In millions) Level 1 Level 2 Level 3 Netting and Collateral (a) Net Carrying Value on Balance Sheet (b) Collateral Pledged Not Offset Commodity derivative instruments, assets $ 104 $ 2 $ 7 $ (62 ) $ 51 $ — Other assets 2 — — N/A 2 — Total assets at fair value $ 106 $ 2 $ 7 $ (62 ) $ 53 $ — Commodity derivative instruments, liabilities $ 39 $ — $ — $ (39 ) $ — $ — Embedded derivatives in commodity contracts (c) — — 32 — 32 — Contingent consideration, liability (d) — — 317 N/A 317 — Total liabilities at fair value $ 39 $ — $ 349 $ (39 ) $ 349 $ — (a) Represents the impact of netting assets, liabilities and cash collateral when a legal right of offset exists. As of March 31, 2016 , cash collateral of $40 million was netted with the mark-to-market derivative liabilities. As of December 31, 2015 , $23 million was netted with mark-to-market derivative assets. (b) We have no derivative contracts that are subject to master netting arrangements that are reflected gross on the balance sheet. (c) Includes $6 million and $5 million classified as current at March 31, 2016 and December 31, 2015 , respectively. (d) Includes $200 million and $196 million classified as current at March 31, 2016 and December 31, 2015 , respectively. Commodity derivatives in Level 1 are exchange-traded contracts for crude oil and refined products measured at fair value with a market approach using the close-of-day settlement prices for the market. Commodity derivatives are covered under master netting agreements with an unconditional right to offset. Collateral deposits in futures commission merchant accounts covered by master netting agreements related to Level 1 commodity derivatives are classified as Level 1 in the fair value hierarchy. Commodity derivatives in Level 2 include crude oil and natural gas swap contracts and are measured at fair value with a market approach. The valuations are based on the appropriate commodity prices and contain no significant unobservable inputs. LIBO Rates are an observable input for the measurement of these derivative contracts. The measurements for commodity contracts contain observable inputs in the form of forward prices based on WTI crude oil prices; and Columbia Appalachia, Henry Hub, PEPL and Houston Ship Channel natural gas prices. Level 3 instruments include OTC NGL contracts and embedded derivatives in commodity contracts. The fair value calculation for these Level 3 instruments used significant unobservable inputs including: (1) NGL prices interpolated and extrapolated due to inactive markets ranging from $0.17 to $3.37 per gallon, (2) electricity prices ranging from $21.34 to $44.27 per megawatt hour and (3) the probability of renewal of 50 percent for the first five -year term and 75 percent for the second five -year term of the gas purchase agreement and the related keep-whole processing agreement. For these contracts, increases in forward NGL prices result in a decrease in the fair value of the derivative assets and an increase in the fair value of the derivative liabilities. The forward prices for the individual NGL products generally increase or decrease in a positive correlation with one another. The embedded derivative liability relates to a natural gas purchase agreement embedded in a keep‑whole processing agreement. Increases or decreases in forward NGL prices result in an increase or decrease in the fair value of the embedded derivative. An increase in the probability of renewal would result in an increase in the fair value of the related embedded derivative liability. The contingent consideration represents the fair value as of March 31, 2016 and December 31, 2015 of the remaining amount we expect to pay to BP related to the earnout provision associated with our 2013 acquisition of BP’s refinery in Texas City, Texas and related logistics and marketing assets. We refer to these assets as the “Galveston Bay Refinery and Related Assets.” The fair value of the remaining contingent consideration was estimated using an income approach and is therefore a Level 3 liability. The amount of cash to be paid under the arrangement is based on both a market-based crack spread and refinery throughput volumes for the months during which the earnout applies, as well as established thresholds that cap the annual and total payment. The earnout payment cannot exceed $200 million per year for the first three years of the arrangement or $250 million per year for the last three years of the arrangement, with the total cumulative payment capped at $700 million over the six-year period commencing in 2014. Any excess or shortfall from the annual cap for a current year’s earnout calculation will not affect subsequent years’ calculations. The fair value calculation used significant unobservable inputs, including: (1) an estimate of monthly refinery throughput volumes; (2) a range of internal and external monthly crack spread forecasts from approximately $9 to $16 per barrel; and (3) a range of risk-adjusted discount rates from four percent to 9 percent . An increase or decrease in crack spread forecasts or refinery throughput volume expectations may result in a corresponding increase or decrease in the fair value. Increases to the fair value as a result of increasing forecasts for both of these unobservable inputs, however, are limited as the earnout payment is subject to annual caps. An increase or decrease in the discount rate may result in a decrease or increase to the fair value, respectively. The fair value of the contingent consideration is reassessed each quarter, with changes in fair value recorded in cost of revenues. During the second quarter of 2016, we paid BP $200 million for the third year’s contingent earnout. Including this second quarter payment, we have paid BP approximately $569 million in total leaving $131 million remaining under the total cap of $700 million . The following is a reconciliation of the beginning and ending balances recorded for liabilities classified as Level 3 in the fair value hierarchy. Three Months Ended (In millions) 2016 2015 Beginning balance $ 342 $ 478 Unrealized and realized losses included in net income 12 12 Settlements of derivative instruments 4 — Ending balance $ 358 $ 490 We held Level 3 derivative instruments during the three months ended March 31, 2016 which were acquired with the MarkWest Merger, but we did not hold any Level 3 derivative instruments during the three months ended March 31, 2015 . See Note 16 for the income statement impacts of our derivative instruments. There was an unrealized loss of $5 million in the three months ended March 31, 2016 related to derivatives. There was an unrealized loss of $7 million and $12 million in the three months ended March 31, 2016 and 2015 , respectively, related to the contingent consideration. Fair Values - Nonrecurring The following table shows the values of assets, by major category, measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition. Three Months Ended March 31, 2016 2015 (In millions) Fair Value Impairment Fair Value Impairment Goodwill $ — $ 129 $ — $ — See Note 14 for additional information on the goodwill impairment. Fair Values – Reported The following table summarizes financial instruments on the basis of their nature, characteristics and risk at March 31, 2016 and December 31, 2015 , excluding the derivative financial instruments and contingent consideration reported above. March 31, 2016 December 31, 2015 (In millions) Fair Value Carrying Value Fair Value Carrying Value Financial assets: Investments $ 30 $ 2 $ 33 $ 2 Other 35 35 35 33 Total financial assets $ 65 $ 37 $ 68 $ 35 Financial liabilities: Long-term debt (a) $ 11,086 $ 11,276 $ 11,366 $ 11,628 Deferred credits and other liabilities 140 138 136 135 Total financial liabilities $ 11,226 $ 11,414 $ 11,502 $ 11,763 (a) Excludes capital leases and debt issuance costs, however, includes amount classified as debt due within one year. Our current assets and liabilities include financial instruments, the most significant of which are trade accounts receivable and payables. We believe the carrying values of our current assets and liabilities approximate fair value. Our fair value assessment incorporates a variety of considerations, including (1) the short-term duration of the instruments, (2) our investment-grade credit rating and (3) our historical incurrence of and expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk. Fair values of our financial assets included in investments and other financial assets and of our financial liabilities included in deferred credits and other liabilities are measured primarily using an income approach and most inputs are internally generated, which results in a Level 3 classification. Estimated future cash flows are discounted using a rate deemed appropriate to obtain the fair value. Other financial assets primarily consist of environmental remediation receivables. Deferred credits and other liabilities primarily consist of a liability related to SMR, a payable for merger cash consideration due to MPLX’s Class B unitholders to be paid upon conversion, insurance liabilities and environmental remediation liabilities. Fair value of fixed-rate long-term debt is measured using a market approach, based upon the average of quotes from major financial institutions and a third-party service for our debt. Because these quotes cannot be independently verified to the market, they are considered Level 3 inputs. Fair value of variable-rate long-term debt approximates the carrying value. |

Benefit payments related to unfunded pension and other postretirement benefit plans were $2 million and $7 million , respectively, during the three months ended March 31, 2016 . During the three months ended March 31, 2016 and 2015 , we determined that certain of our pension plans’ lump sum payments to employees retiring in the respective years will exceed the plans’ total service and interest costs for the year. Settlement losses are required to be recorded when lump sum payments exceed total service and interest costs. As a result, during the three months ended March 31, 2016 and 2015 , we recorded pension settlement expenses of $1 million related to our lump sum payments made during both the first three months of 2016 and 2015 . |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies We are the subject of, or a party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Some of these matters are discussed below. For matters for which we have not recorded an accrued liability, we are unable to estimate a range of possible loss because the issues involved have not been fully developed through pleadings and discovery. However, the ultimate resolution of some of these contingencies could, individually or in the aggregate, be material. Environmental matters —We are subject to federal, state, local and foreign laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites and certain other locations including presently or formerly owned or operated retail marketing sites. Penalties may be imposed for noncompliance. At March 31, 2016 and December 31, 2015 , accrued liabilities for remediation totaled $166 million and $163 million , respectively. It is not presently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties if any that may be imposed. Receivables for recoverable costs from certain states, under programs to assist companies in clean-up efforts related to underground storage tanks at presently or formerly owned or operated retail marketing sites, were $68 million and $70 million at March 31, 2016 and December 31, 2015 , respectively. We are involved in a number of environmental enforcement matters arising in the ordinary course of business. While the outcome and impact on us cannot be predicted with certainty, management believes the resolution of these environmental matters will not, individually or collectively, have a material adverse effect on our consolidated results of operations, financial position or cash flows. Litigation Relating to the MarkWest Merger —In July 2015, a purported class action lawsuit asserting claims challenging the MarkWest Merger was filed in the Court of Chancery of the State of Delaware by a purported unitholder of MarkWest. In August 2015, two similar putative class action lawsuits were filed in the Court of Chancery of the State of Delaware by plaintiffs who purport to be unitholders of MarkWest. On September 9, 2015, these lawsuits were consolidated into one action pending in the Court of Chancery of the State of Delaware, now captioned In re MarkWest Energy Partners, L.P. Unitholder Litigation . On October 1, 2015, the plaintiffs filed a consolidated complaint against the individual members of the board of directors of MarkWest Energy GP, L.L.C. (the “MarkWest GP Board”), MPLX, MPLX GP, MPC and Sapphire Holdco LLC, a wholly-owned subsidiary of MPLX, asserting in connection with the MarkWest Merger and related disclosures that, among other things, (i) the MarkWest GP Board breached its duties in approving the MarkWest Merger with MPLX and (ii) MPC, MPLX, MPLX GP, and Sapphire Holdco LLC aided and abetted such breaches. On February 4, 2016, the Court approved a stipulation and proposed order to dismiss all claims with prejudice as to the named plaintiffs, but the Court retained jurisdiction to adjudicate an application for a mootness fee by the plaintiffs’ counsel for an award of attorneys’ fees and reimbursement of expenses. On March 28, 2016, the plaintiffs filed an application for reimbursement of approximately $2 million of legal fees and expenses. We intend to vigorously defend against any application for a mootness fee and do not expect the resolution of such matter to have a material adverse effect. MarkWest Environmental Proceeding – On July 6, 2015, representatives from the EPA and the United States Department of Justice entered a MarkWest Liberty Midstream & Resources, L.L.C., a wholly-owned subsidiary of MPLX (“MarkWest Liberty Midstream”) pipeline launcher/receiver site utilized for pipeline maintenance operations in Washington County, Pennsylvania pursuant to a search warrant issued by a magistrate of the United States District Court for the Western District of Pennsylvania. The government has presented MarkWest Liberty Midstream with subpoenas to provide documents related to its pipeline and compressor facilities located in Pennsylvania. MarkWest Liberty Midstream is providing information in response to the subpoenas and related requests for information from EPA, state and other agencies, and is in discussions with the agencies regarding issues associated with its operations of, and any permit related obligations for, its gathering facilities in the region. Immediately following the July 6, 2015 search, MarkWest Liberty Midstream commenced its own assessment of its operations of launcher/receiver facilities. MarkWest Liberty Midstream’s review to date has determined that MarkWest Liberty Midstream’s operations have been conducted in a manner fully protective of its employees and the public, and that other than potentially having to obtain certain permits at a relatively small number of individual sites, MarkWest Liberty has operated in substantial compliance with applicable laws and regulations. It is possible that, in connection with any potential or asserted civil or criminal enforcement action associated with this matter, MarkWest Liberty Midstream will incur material assessments, penalties or fines, incur material defense costs and expenses, be required to modify operations or construction activities which could increase operating costs and capital expenditures, or be subject to other obligations or restrictions that could restrict or prohibit our activities, any or all of which could adversely affect our results of operations, financial position or cash flows. The amount of any potential assessments, penalties, fines, restrictions, requirements, modifications, costs or expenses that may be incurred in connection with any potential enforcement action cannot be reasonably estimated or determined at this time. Other Lawsuits —In May 2015, the Kentucky attorney general filed a lawsuit against our wholly-owned subsidiary, Marathon Petroleum Company LP (“MPC LP”) in the United States District Court for the Western District of Kentucky asserting claims under federal and state antitrust statutes, the Kentucky Consumer Protection Act, and state common law. The complaint, as amended in July 2015, alleges that MPC LP used deed restrictions, supply agreements with customers and exchange agreements with competitors to unreasonably restrain trade in areas within Kentucky and seeks declaratory relief, unspecified damages, civil penalties, restitution and disgorgement of profits. At this early stage, the ultimate outcome of this litigation remains uncertain, and neither the likelihood of an unfavorable outcome nor the ultimate liability, if any, can be determined, and we are unable to estimate a reasonably possible loss (or range of loss) for this matter. We intend to vigorously defend ourselves in this matter. In May 2007, the Kentucky attorney general filed a lawsuit against us and Marathon Oil in state court in Franklin County, Kentucky for alleged violations of Kentucky’s emergency pricing and consumer protection laws following Hurricanes Katrina and Rita in 2005. The lawsuit alleges that we overcharged customers by $89 million during September and October 2005 . The complaint seeks disgorgement of these sums, as well as penalties, under Kentucky’s emergency pricing and consumer protection laws. We are vigorously defending this litigation. We believe that this is the first lawsuit for damages and injunctive relief under the Kentucky emergency pricing laws to progress this far and it contains many novel issues. In May 2011, the Kentucky attorney general amended his complaint to include a request for immediate injunctive relief as well as unspecified damages and penalties related to our wholesale gasoline pricing in April and May 2011 under statewide price controls that were activated by the Kentucky governor on April 26, 2011 and which have since expired. The court denied the attorney general’s request for immediate injunctive relief, and the remainder of the 2011 claims likely will be resolved along with those dating from 2005. If the lawsuit is resolved unfavorably in its entirety, it could materially impact our consolidated results of operations, financial position or cash flows. However, management does not believe the ultimate resolution of this litigation will have a material adverse effect. We are also a party to a number of other lawsuits and other proceedings arising in the ordinary course of business. While the ultimate outcome and impact to us cannot be predicted with certainty, we believe that the resolution of these other lawsuits and proceedings will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. Guarantees— We have provided certain guarantees, direct and indirect, of the indebtedness of other companies. Under the terms of most of these guarantee arrangements, we would be required to perform should the guaranteed party fail to fulfill its obligations under the specified arrangements. In addition to these financial guarantees, we also have various performance guarantees related to specific agreements. Guarantees related to indebtedness of equity method investees —We hold interests in an offshore oil port, LOOP, and a crude oil pipeline system, LOCAP. Both LOOP and LOCAP have secured various project financings with throughput and deficiency agreements. Under the agreements, we are required to advance funds if the investees are unable to service their debt. Any such advances are considered prepayments of future transportation charges. The duration of the agreements vary but tend to follow the terms of the underlying debt, which extend through 2037 . Our maximum potential undiscounted payments under these agreements for the debt principal totaled $172 million as of March 31, 2016 . We hold an interest in a refined products pipeline through our investment in Centennial, and have guaranteed our portion of the payment of Centennial’s principal, interest and prepayment costs, if applicable, under a Master Shelf Agreement, which is scheduled to expire in 2024 . The guarantee arose in order for Centennial to obtain adequate financing. Our maximum potential undiscounted payments under this agreement for debt principal totaled $33 million as of March 31, 2016 . In connection with our 50 percent ownership in Crowley Ocean Partners, we have agreed to conditionally guarantee our portion of the obligations of the joint venture and its subsidiaries under a senior secured term loan agreement. The term loan agreement provides for loans of up to $325 million to finance the acquisition of four product tankers. MPC’s liability under the guarantee for each vessel is conditioned upon the occurrence of certain events, including if we cease to maintain an investment grade credit rating or the charter for the relevant product tanker ceases to be in effect and is not replaced by a charter with an investment grade company on certain defined commercial terms. As of March 31, 2016 , our maximum potential undiscounted payments under this agreement for debt principal associated with the delivery of the first two vessels totaled $81 million . Marathon Oil indemnifications— In conjunction with our spinoff from Marathon Oil, we have entered into arrangements with Marathon Oil providing indemnities and guarantees with recorded values of $3 million as of March 31, 2016 , which consist of unrecognized tax benefits related to MPC, its consolidated subsidiaries and the refining, marketing and transportation business operations prior to our spinoff which are not already reflected in the unrecognized tax benefits described in Note 11 , and other contingent liabilities Marathon Oil may incur related to taxes. Furthermore, the separation and distribution agreement and other agreements with Marathon Oil to effect our spinoff provide for cross-indemnities between Marathon Oil and us. In general, Marathon Oil is required to indemnify us for any liabilities relating to Marathon Oil’s historical oil and gas exploration and production operations, oil sands mining operations and integrated gas operations, and we are required to indemnify Marathon Oil for any liabilities relating to Marathon Oil’s historical refining, marketing and transportation operations. The terms of these indemnifications are indefinite and the amounts are not capped. Other guarantees —We have entered into other guarantees with maximum potential undiscounted payments totaling $89 million as of March 31, 2016 , which primarily consist of a commitment to contribute cash to an equity method investee for certain catastrophic events, up to $50 million per event, in lieu of procuring insurance coverage and leases of assets containing general lease indemnities and guaranteed residual values. General guarantees associated with dispositions – Over the years, we have sold various assets in the normal course of our business. Certain of the related agreements contain performance and general guarantees, including guarantees regarding inaccuracies in representations, warranties, covenants and agreements, and environmental and general indemnifications that require us to perform upon the occurrence of a triggering event or condition. These guarantees and indemnifications are part of the normal course of selling assets. We are typically not able to calculate the maximum potential amount of future payments that could be made under such contractual provisions because of the variability inherent in the guarantees and indemnities. Most often, the nature of the guarantees and indemnities is such that there is no appropriate method for quantifying the exposure because the underlying triggering event has little or no past experience upon which a reasonable prediction of the outcome can be based. Contractual commitments and contingencies— At March 31, 2016 , our contractual commitments to acquire property, plant and equipment and advance funds to equity method investees totaled $1.7 billion , which includes $331 million of contingent consideration associated with the acquisition of the Galveston Bay Refinery and Related Assets, $625 million for contributions to North Dakota Pipeline and $69 million for contributions to Crowley Ocean Partners. See Note 4 for additional information on our investments in North Dakota Pipeline and Crowley Ocean Partners. See Note 15 for additional information on the contingent consideration. Certain natural gas processing and gathering arrangements require us to construct new natural gas processing plants, natural gas gathering pipelines and NGL pipelines and contain certain fees and charges if specified construction milestones are not achieved for reasons other than force majeure. In certain cases, certain producers may have the right to cancel the processing arrangements if there are significant delays that are not due to force majeure. As of March 31, 2016 , management does not believe there are any indications that we will not be able to meet the construction milestones, that force majeure does not apply, or that such fees and charges will otherwise be triggered. |

Subsequent Events [Abstract] | |
Subsequent Event | Subsequent Event On April 27, 2016, MPLX entered into an agreement for the private placement of $1 billion of newly authorized 6.5 percent Series A Convertible Preferred Units (the “Preferred Units”) at a price of $32.50 per unit or approximately 30.8 million units. The Preferred Units will be entitled to receive an annual distribution from MPLX, which will initially equal $2.1125 per unit. The Preferred Units are convertible into MPLX common units on a one for one basis after three years, at the purchasers’ option, and after four years at MPLX’s option, subject to certain conditions. Closing of the transaction is scheduled to occur in May 2016. The net proceeds after deducting offering and transaction expenses are expected to be approximately $984 million . |

Accounting Policies [Abstract] | |
Use of estimates | These interim consolidated financial statements are unaudited; however, in the opinion of our management, these statements reflect all adjustments necessary for a fair statement of the results for the periods reported. All such adjustments are of a normal, recurring nature unless otherwise disclosed. These interim consolidated financial statements, including the notes, have been prepared in accordance with the rules of the SEC applicable to interim period financial statements and do not include all of the information and disclosures required by U.S. GAAP for complete financial statements. |
Inventories | Inventories are carried at the lower of cost or market value. Costs of crude oil, refinery feedstocks and refined products are aggregated on a consolidated basis for purposes of assessing if the LIFO cost basis of these inventories may have to be written down to market values. The December 31, 2015 lower of cost or market reserve was reversed due to the sale of inventory quantities that gave rise to the 2015 reserve. A new lower of cost or market reserve of $385 million was established as of March 31, 2016 based on prices at that time. The effect of the change in lower of cost or market reserve was a $15 million charge to cost of revenues for the three months ended March 31, 2016 . Based on movements of refined product prices, future inventory valuation adjustments could have a negative or positive effect to earnings. Such losses are subject to reversal in subsequent periods if prices recover. The cost of inventories of crude oil and refinery feedstocks, refined products and merchandise is determined primarily under the LIFO method. |
Derivative instruments | Derivatives that are not designated as accounting hedges may include commodity derivatives used to hedge price risk on (1) inventories, (2) fixed price sales of refined products, (3) the acquisition of foreign-sourced crude oil, (4) the acquisition of ethanol for blending with refined products, (5) the sale of NGLs, (6) the purchase of natural gas and (7) the purchase of electricity. |
Stock-based compensation arrangements | The fair value of stock options granted to our employees is estimated on the date of the grant using the Black Scholes option-pricing model, which employs various assumptions. |
