The Schedule 13D is not modified except as specifically provided herein. Any terms capitalized but not defined herein shall have the same meaning as defined in the Schedule 13D.


Item 1.			Security and Issuer.

No changes to this Item.


Item 2.			Identity and Background.

(a)The reporting persons are:

i.MPC, which wholly owns MPC Investment LLC (“MPC Investment”) and Andeavor LLC (“Andeavor”). The name of each director and executive officer of MPC, and each individual’s principal occupation, is set forth on Schedule I to this Schedule 13D;

vii.TTC Holdings LLC (“TTC Holdings”), a Delaware limited liability company that is wholly owned by Western Refining; and

viii.Giant Industries, Inc. (“Giant”), a Delaware corporation that is wholly owned by TTC Holdings.

The Reporting Persons are making this single, joint filing pursuant to Rule 13d-1(k) under the Act. The agreement among the Reporting Persons to file this Schedule 13D jointly is filed as Exhibit 99.1 hereto.

(b)The business address of MPC, MPC Investment, Andeavor, Western Refining, TTC Holdings, Giant and each person listed in Schedule I is 539 S. Main Street, Findlay, Ohio 45840. The business address of MPLX Logistics and MPLX GP is 200 E. Hardin Street, Findlay, Ohio 45840.

(c)MPC, MPC Investment, MPLX Logistics, Andeavor, Western Refining, TTC Holdings and Giant are holding companies, the assets of which consist of direct and indirect ownership interests in, and the business of which is conducted substantially through, their subsidiaries. MPLX GP serves as the general partner of the Issuer.

(d)Within the last five years, none of the Reporting Persons nor, to the knowledge of the Reporting Persons, any person named in Schedule I, has been convicted in any criminal proceedings (excluding traffic violations or similar misdemeanors)

(e)On October 15, 2020, the United States Securities and Exchange Commission (the “SEC”) announced an agreement with Andeavor LLC, as successor-by-merger to Andeavor and a wholly owned subsidiary of MPC, to settle an investigation regarding Andeavor’s historical share repurchase activity. As part of the settlement with the SEC, Andeavor LLC agreed to pay a $20 million penalty and consent to the entry of an Administrative Order containing findings that Andeavor violated Section 13(b)(2)(B) of the Act, and ordering Andeavor LLC to cease and desist from

committing or causing any violations and any future violations of that provision. Andeavor LLC neither admitted nor denied the SEC’s findings.

Other than as set forth above in this Item 2, within the last five years none of the Reporting Persons nor, to the knowledge of the Reporting Persons, any person named in Schedule I, has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f)The citizenship of each of the Reporting Persons is set forth in paragraph (a) of this Item. The citizenship of each of the directors and executive officers of MPC is set forth in Schedule I to this Schedule 13D.

The Issuer is managed and operated by the board of directors and executive officers of MPLX GP, its general partner. MPC Investment, a direct wholly owned subsidiary of MPC, owns all of the membership interests in MPLX GP and has the right to appoint the entire board of directors of MPLX GP. Accordingly, MPLX GP is an indirect wholly owned subsidiary of MPC.


Item 3.			Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended and supplemented as follows:

The information previously provided in response to Item 3 is hereby amended and supplemented by adding the following:

On December 31, 2020, Western Refining Southwest, Inc. (“WRSW”), an Arizona corporation and indirect wholly owned subsidiary of MPC, Tesoro Refining & Marketing Company LLC (“Tesoro Refining”) and Tesoro Alaska Company LLC (“Tesoro Alaska”), Delaware limited liability companies, Tesoro Logistics GP, LLC, a Delaware limited liability company and indirect wholly owned subsidiary of MPC (“TLGP”), Western Refining, TTC, Giant and the other signatories thereto, entered into a reorganization agreement providing for a series of intercompany transactions (collectively, the “Reorganization”) pursuant to which, among other things: (i) Tesoro Refining and Tesoro Alaska, effective 12:01 a.m. on January 1, 2021 (the “Reorganization Date”), distributed to WRSW all of the outstanding limited liability company interests in TLGP held by each of Tesoro Refining and Tesoro Alaska immediately prior to such distribution; (ii) TLGP, effective 12:02 a.m. on the Reorganization Date, distributed to WRSW all of the MPLX Common Units held by TLGP prior to such distribution; (iii) WRSW, effective 12:16 a.m. on the Reorganization Date, converted to a Delaware limited liability company under the name Western Refining Southwest LLC (“WRSWL”); (iv) WRSWL, effective 12:17 a.m. on the Reorganization Date, distributed to Giant all of the (x) MPLX Common Units, (y) MPLX TexNew Mex units and (z) the MPLX Special Limited Partner Interest held, in each case, by WRSWL immediately prior to such distribution; and (v) Western Refining, effective 12:21 a.m. on the Reorganization Date, contributed all of the outstanding capital stock of Giant to TTC Holdings. The transactions were undertaken as part of a broader internal reorganization of MPC’s Refining & Marketing and Retail segments and were designed to satisfy certain requirements related to the liquidation and reorganization of entities as set forth in the Internal Revenue Code of 1986, as amended.

After giving effect to the transactions undertaken in connection with the Reorganization, Giant is the record holder of 142,713,518 MPLX Common Units, representing approximately 13.7% of the issued and outstanding MPLX Common Units, based upon 1,038,727,278 MPLX Common Units issued and outstanding as of January 4, 2021, as reported by the Issuer to the Reporting Persons. Each of WRSWL, TLGP, Tesoro Refining and Tesoro Alaska ceased to hold, directly or indirectly, any MPLX Common Units.

After giving effect to the transactions undertaken in connection with the Reorganization, Giant is a wholly owned subsidiary of TTC Holdings, which is a wholly owned subsidiary of Western Refining, which is a wholly owned subsidiary of Andeavor, which is a wholly owned subsidiary of MPC. As a result, MPC, Andeavor, Western Refining and TTC Holdings may be deemed to beneficially own MPLX Common Units held by Giant.


Item 4.			Purpose of the Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

The information provided or incorporated by reference in Item 3 above is hereby incorporated by reference into this Item 4, as applicable.

Depending on the factors discussed herein, the Reporting Persons may, from time to time, acquire, retain or sell all or a portion of the MPLX Common Units in the open market or in privately negotiated transactions. Any actions the Reporting Persons might undertake will be dependent upon the Reporting Persons’ review of numerous factors, including, among other things, the price levels of the MPLX Common Units; general market and economic conditions; ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; the relative attractiveness of alternative business and investment opportunities; and other future developments.

The Reporting Persons have no present plans or proposals that would result in or relate to any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.


Item 5.			Interest in Securities of the Issuer.

The information previously provided in response to Item 5 is hereby amended and restated as follows.

(a) - (b) The information provided in Items 7 through 11 of the cover pages of this Schedule 13D is incorporated herein by reference.

(c) Except as described herein or as set forth in Schedule I of this Schedule 13D, none of the Reporting Persons nor any person listed on Schedule I has effected any transactions in the Issuer’s Common Units within the past 60 days.

(d) The Reporting Persons have the right to receive distributions from, and the proceeds from the sale of, the respective MPLX Common Units reported by such persons on the cover pages of this Schedule 13D and in this Item 5. None of the Reporting Persons have any knowledge of any other person having the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of, the MPLX Common Units held in the name of the Reporting Persons.

(e) Not applicable.


Item 6.			Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

The information previously provided in response to Item 6 is hereby amended and supplemented by adding the following:

The information provided or incorporated by reference in Item 3 above is hereby incorporated by reference into this Item 6.
