1.			Based upon 1,022,236,667 MPLX Common Units issued and outstanding as of May 8, 2024, with such figure provided to the Reporting Persons by the Issuer.

Explanatory Note: This Amendment No. 17 amends and supplements the statement on Schedule 13D filed by Marathon Petroleum Corporation (“MPC”) and certain of its subsidiaries concerning the common units representing limited partner interests (“MPLX Common Units”) in MPLX LP (the “Issuer”) filed on December 3, 2014, as amended on December 12, 2014, August 19, 2015, December 7, 2015, April 4, 2016, March 6, 2017, September 1, 2017, December 18, 2017, February 5, 2018, October 1, 2018, November 5, 2018, May 9, 2019, August 2, 2019, August 4, 2020, January 5, 2021, September 22, 2021 and October 4, 2022 (the “Schedule 13D”). The Schedule 13D is not modified except as specifically provided herein. Any term capitalized but not defined herein shall have the same meaning as defined in the Schedule 13D.

This Amendment No. 17 is being filed to report the decrease in the percentage of MPLX Common Units beneficially owned by the Reporting Persons since the previous reporting date on account of an increase in the number of MPLX Common Units outstanding as a result of conversions of the Issuer’s Series A Convertible Preferred Units into MPLX Common Units.


Item 1.			Security and Issuer.

There are no changes to this Item.


Item 2.			Identity and Background.

(a)The reporting persons are:

iii.MPLX Logistics Holdings LLC (“MPLX Logistics”), a Delaware limited liability company that is wholly owned by MPC Investment;

iv.MPLX GP LLC (“MPLX GP”), a Delaware limited liability company that is wholly owned by MPC Investment;

v.Andeavor LLC, a Delaware limited liability company that is wholly owned by MPC;

(c)MPC, MPC Investment, MPLX Logistics, Andeavor LLC, 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 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.
