Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Principles of Consolidation	Organization and Principles of Consolidation As used in this document, the terms “Partnership,” “SUN,” “we,” “us,” and “our” should be understood to refer to Sunoco LP and our consolidated subsidiaries, unless the context clearly indicates otherwise. We are a Delaware master limited partnership. We are managed by our general partner, Sunoco GP LLC (“General Partner”), which is owned by Energy Transfer LP (“ET”). Prior to April 1, 2021, Energy Transfer Operating, L.P. (“ETO”), owned our General Partner. On April 1, 2021, ETO merged into ET with ET surviving the merger. As of March 31, 2021, and immediately prior to such merger, ETO and its subsidiaries owned 100% of the membership interests in our General Partner, all of our incentive distribution rights (“IDRs”) and approximately 34.2% of our common units, which constitutes a 28.5% limited partner interest in us. The consolidated financial statements are composed of Sunoco LP, a publicly traded Delaware limited partnership, and our wholly‑owned subsidiaries. Our primary operations are conducted by the following consolidated subsidiaries: • Sunoco, LLC (“Sunoco LLC”), a Delaware limited liability company, primarily distributes motor fuel in 30 states throughout the East Coast, Midwest, South Central and Southeast regions of the United States. Sunoco LLC also processes transmix and distributes refined product through its terminals in Alabama, Texas, Arkansas and New York. • Sunoco Retail LLC (“Sunoco Retail”), a Pennsylvania limited liability company, owns and operates retail stores that sell motor fuel and merchandise primarily in New Jersey. Sunoco Retail also leases owned sites to commission agents who sell motor fuels to the motoring public on Sunoco Retail's behalf for a commission. • Aloha Petroleum LLC, a Delaware limited liability company, distributes motor fuel and operates terminal facilities on the Hawaiian Islands. • Aloha Petroleum, Ltd. (“Aloha”), a Hawaii corporation, owns and operates retail stores on the Hawaiian Islands. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain items have been reclassified for presentation purposes to conform to the accounting policies of the consolidated entity. These reclassifications had no material impact on income (loss) from operations, net income (loss) and comprehensive income (loss), the balance sheets or statements of cash flows.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Interim Financial Statements The accompanying interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Pursuant to Regulation S-X, certain information and disclosures normally included in the annual financial statements have been condensed or omitted. The interim consolidated financial statements and notes included herein should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 19, 2021. Significant Accounting Policies As of March 31, 2021, there have been no changes in the Partnership's significant accounting policies from those described in the Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 19, 2021. Motor Fuel and Sales Taxes For bulk sales, certain motor fuel and sales taxes are collected from customers and remitted to governmental agencies either directly by the Partnership or through suppliers. The Partnership’s accounting policy for direct sales to dealer and commercial customers is to exclude the collected motor fuel tax from sales and cost of sales. For other locations where the Partnership holds inventory, including commission agent arrangements and Partnership-operated retail locations, motor fuel sales and motor fuel cost of sales include motor fuel taxes. Such amounts were $76 million and $80 million for the three months ended March 31, 2021 and 2020, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in the accompanying consolidated statements of operations and comprehensive income (loss).

Commitments And Contingencies

Commitments And Contingencies	3 Months Ended

Leases [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation We have at various points and may in the future become involved in various legal proceedings arising out of our operations in the normal course of business. These proceedings would be subject to the uncertainties inherent in any litigation, and we regularly assess the need for accounting recognition or disclosure of these contingencies. We would expect to defend ourselves vigorously in all such matters. Based on currently available information, we believe it is unlikely that the outcome of known matters would have a material adverse impact on our financial condition, results of operations or cash flows. Lessee Accounting The Partnership leases retail stores, other property, and equipment under non-cancellable operating leases whose initial terms are typically 5 to 15 years, with some having a term of 40 years or more, along with options that permit renewals for additional periods. At the inception of each, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify leased assets as operating or finance. The Partnership has elected not to record any leases with terms of 12 months or less on the balance sheet. At this time, the majority of active leases within our portfolio are classified as operating leases. Operating leases are included in lease right-of-use (“ROU”) assets, operating lease current liabilities, and operating lease noncurrent liabilities in our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in ROU assets and long-term debt in our consolidated balance sheets. The ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make minimum lease payments arising from the lease for the duration of the lease term. Most leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 20 years or greater. The exercise of lease renewal options is typically at our discretion. Additionally, many leases contain early termination clauses; however, early termination typically requires the agreement of both parties to the lease. At lease inception, all renewal options reasonably certain to be exercised are considered when determining the lease term. At this time, the Partnership does not have leases that include options to purchase or automatic transfer of ownership of the leased property to the Partnership. The depreciable life of leased assets and leasehold improvements are limited by the expected lease term. To determine the present value of future minimum lease payments, we use the implicit rate when readily determinable. At this time, many of our leases do not provide an implicit rate; therefore, to determine the present value of minimum lease payments we use our incremental borrowing rate based on the information available at lease commencement date. The ROU assets also include any lease payments made on or before the commencement date and exclude lease incentives. Minimum rent payments are expensed on a straight-line basis over the term of the lease. In addition, some leases may require additional contingent or variable lease payments based on factors specific to the individual agreement. Variable lease payments we are typically responsible for include payment of real estate taxes, maintenance expenses and insurance. The details of the Partnership's operating and finance lease liabilities are as follows: March 31, Lease Term and Discount Rate 2021 2020 Weighted-average remaining lease term (years) Operating leases 23 25 Finance leases 21 5 Weighted-average discount rate (%) Operating leases 6 % 6 % Finance leases 5 % 5 % Three Months Ended March 31, Other information 2021 2020 (in millions) Cash paid for amount included in the measurement of lease liabilities Operating cash flows from operating leases $ (13) $ (13) Operating cash flows from finance leases $ — $ — Financing cash flows from finance leases $ — $ (2) Leased assets obtained in exchange for new finance lease liabilities $ 9 $ — Leased assets obtained in exchange for new operating lease liabilities $ 5 $ 9 Maturity of lease liabilities (as of March 31, 2021) Operating leases Finance leases Total (in millions) 2021 (remainder) $ 37 $ 1 $ 38 2022 49 1 50 2023 47 1 48 2024 46 1 47 2025 45 1 46 Thereafter 815 20 835 Total lease payment 1,039 25 1,064 Less: interest 492 9 501 Present value of lease liabilities $ 547 $ 16 $ 563 Lessor Accounting

Income Tax Expense	Income Tax Expense As a partnership, we are generally not subject to federal income tax and most state income taxes. However, the Partnership conducts certain activities through corporate subsidiaries which are subject to federal and state income taxes. Our effective tax rate differs from the statutory rate primarily due to Partnership earnings that are not subject to U.S. federal and most state income taxes at the Partnership level. A reconciliation of income tax expense from continuing operations at the U.S. federal statutory rate of 21% to net income tax expense is as follows: Three Months Ended March 31, 2021 2020 (in millions) Income tax expense at statutory federal rate $ 33 $ (26) Partnership earnings not subject to tax (31) 26 State and local tax, net of federal benefit 1 2 Other — 1 Net income tax expense $ 3 $ 3

For purposes of maintaining partner capital accounts, the Partnership Agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect to incentive cash distributions, which are allocated 100% to ETO.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segment Reporting Our financial statements reflect two reportable segments, Fuel Distribution and Marketing and All Other. We report Adjusted EBITDA by segment as a measure of segment performance. We define Adjusted EBITDA as earnings before net interest expense, income tax expense and depreciation, amortization and accretion expense, non-cash unit-based compensation expense, gains and losses on disposal of assets and non-cash impairment charges, unrealized gains and losses on commodity derivatives, inventory adjustments, and certain other operating expenses reflected in net income that we do not believe are indicative of ongoing core operations.

For other locations where the Partnership holds inventory, including commission agent arrangements and Partnership-operated retail locations, motor fuel sales and motor fuel cost of sales include motor fuel taxes. Such amounts were $76 million and $80 million for the three months ended March 31, 2021 and 2020, respectively.
