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 Operating, L.P. (“ETO”), a consolidated subsidiary of Energy Transfer LP (“ET”). As of September 30, 2020, ETO and its subsidiaries owned 100% of the membership interests in our General Partner, all of our incentive distribution rights (“IDRs”) and approximately 34.3% of our common units, which constitutes a 28.6% 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. • 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 from operations, net income and comprehensive income, 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, 2019 filed with the SEC on February 21, 2020. Significant Accounting Policies As of September 30, 2020, the only change in the Partnership's significant accounting policies from those described in the Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on February 21, 2020, was the adoption of Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments , described below under Recently Adopted Accounting Pronouncement . 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 $82 million and $101 million for the three months ended September 30, 2020 and 2019, respectively, and $226 million and $295 million for the nine months ended September 30, 2020 and 2019, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in the accompanying consolidated statements of operations and comprehensive income. Recently Adopted Accounting Pronouncement In June 2016, the Financial Accounting Standards Board issued ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments." ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit loss" and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. The Partnership adopted ASU 2016-13 on January 1, 2020. The impact of the adoption was not material; however, due to the global economic impacts of COVID-19, the Partnership recorded $16 million of current expected credit losses for the nine months ended September 30, 2020.

The Partnership maintains allowances for expected credit losses. Following the adoption of ASU 2016-13, the allowances are based on the best estimate of the amount of expected credit losses in existing accounts receivable. The Partnership determines the allowances based on historical write-off experience by industry, economic data and current expectations of future credit losses. The Partnership reviews the allowances for expected credit losses quarterly.

Related-Party Transactions	Related-Party Transactions We are party to fee-based commercial agreements with various affiliates of ETO for pipeline, terminalling and storage services. We also have agreements with subsidiaries of ETO for the purchase and sale of fuel. On July 1, 2019, we entered into a 50% owned joint venture on the J.C. Nolan diesel fuel pipeline to West Texas. ETO operates the J.C. Nolan pipeline for the joint venture, which transports diesel fuel from Hebert, Texas to a terminal in the Midland, Texas area. Our investment in this unconsolidated joint venture was $137 million and $121 million as of September 30, 2020 and December 31, 2019, respectively. In addition, we recorded income on the unconsolidated joint venture of $1.0 million and $3.0 million for the three and nine months ended September 30, 2020, respectively. For the three and nine months ended September 30, 2019, we recorded income on the unconsolidated joint venture of $0.1 million.

Revenue from Contract with Customer [Text Block]	Revenue Disaggregation of Revenue We operate our business in two primary segments, Fuel Distribution and Marketing and All Other. We disaggregate revenue within the segments by channels. The following table depicts the disaggregation of revenue by channel within each segment: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (in millions) Fuel Distribution and Marketing Segment Dealer $ 586 $ 928 $ 1,621 $ 2,695 Distributor 1,316 2,027 3,428 5,808 Unbranded wholesale 426 667 1,569 1,940 Commission agent 272 419 951 1,233 Non motor fuel sales 14 14 45 49 Lease income 30 31 89 94 Total 2,644 4,086 7,703 11,819 All Other Segment Motor fuel 111 184 300 498 Non motor fuel sales 46 55 140 168 Lease income 4 6 14 13 Total 161 245 454 679 Total revenue $ 2,805 $ 4,331 $ 8,157 $ 12,498 Contract Balances with Customers The balances of receivables from contracts with customers listed in the table below include both current trade receivables and long-term receivables, net of allowance for expected credit losses. The allowance for expected credit losses represents our best estimate of the probable losses associated with potential customer defaults. We estimate the expected credit losses based on historical write-off experience by industry and current expectations of future credit losses. The balances of the Partnership’s contract assets and contract liabilities as of September 30, 2020 and December 31, 2019 are as follows: September 30, 2020 December 31, 2019 (in millions) Contract balances Contract asset $ 123 $ 117 Accounts receivable from contracts with customers $ 225 $ 366 Contract liability $ — $ — The amount of revenue recognized in the three and nine months ended September 30, 2020 that was included in the contract liability balance at the beginning of each period was $0.1 million and $0.3 million , respectively, and $0.1 million and $0.3 million in the three and nine months ended September 30, 2019, respectively. This amount of revenue is a result of changes in the transaction price of the Partnership’s contracts with customers. The difference in the opening and closing balances of the contract asset and contract liability primarily results from the timing difference between the Partnership’s performance and the customer’s payment. Costs to Obtain or Fulfill a Contract The Partnership recognizes an asset from the costs incurred to obtain a contract (e.g. sales commissions) only if it expects to recover those costs. On the other hand, the costs to fulfill a contract are capitalized if the costs are specifically identifiable to a contract, would result in enhancing resources that will be used in satisfying performance obligations in the future, and are expected to be recovered. These capitalized costs are recorded as a part of other current assets and other noncurrent assets and are amortized as a reduction of revenue on a systematic basis consistent with the pattern of transfer of the goods or services to which such costs relate. The amount of amortization on these capitalized costs that the Partnership recognized was $4 million and $14 million

Commitments And Contingencies

Commitments And Contingencies	Sep. 30, 2020
Leases [Abstract]
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 property and equipment under finance leases 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 components of lease expense consisted of the following: Three Months Ended Nine Months Ended Lease cost Classification 2020 2019 2020 2019 (in millions) Operating lease cost Lease expense $ 15 $ 13 $ 41 $ 39 Finance lease cost Amortization of leased assets Depreciation, amortization, and accretion — 2 3 2 Interest on lease liabilities Interest expense — 1 — 1 Short term lease cost Lease expense — 1 2 3 Variable lease cost Lease expense 1 1 3 3 Sublease income Lease income (10) (12) (30) (33) Net lease cost $ 6 $ 6 $ 19 $ 15 September 30, Lease Term and Discount Rate 2020 2019 Weighted-average remaining lease term (years) Operating leases 24 24 Finance leases 9 6 Weighted-average discount rate (%) Operating leases 6 % 6 % Finance leases 8 % 5 % Nine Months Ended September 30, Other information 2020 2019 (in millions) Cash paid for amount included in the measurement of lease liabilities Operating cash flows from operating leases $ (39) $ (39) Operating cash flows from finance leases $ — $ (1) Financing cash flows from finance leases $ (3) $ (2) Leased assets obtained in exchange for new finance lease liabilities $ — $ 37 Leased assets obtained in exchange for new operating lease liabilities $ 11 $ 22 For the nine months ended September 30, 2020, $23 million of finance leases were terminated with no cash impact.

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 September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (in millions) Income tax expense at statutory federal rate $ 22 $ 15 $ 31 $ 50 Partnership earnings not subject to tax (18) (10) (20) (46) State and local tax, net of federal benefit 1 — 4 — Other — 1 1 5 Net income tax expense $ 5 $ 6 $ 16 $ 9

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 net income 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 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. Inventory adjustments that are excluded from the calculation of Adjusted EBITDA represent changes in lower of cost or market reserves on the Partnership's inventory. These amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	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, 2019 filed with the SEC on February 21, 2020.
Recently Issued Accounting Pronouncements	Significant Accounting Policies As of September 30, 2020, the only change in the Partnership's significant accounting policies from those described in the Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on February 21, 2020, was the adoption of Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments , described below under Recently Adopted Accounting Pronouncement
Motor Fuel and Sales Taxes	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 $82 million and $101 million for the three months ended September 30, 2020 and 2019, respectively, and $226 million and $295 million for the nine months ended September 30, 2020 and 2019, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in the accompanying consolidated statements of operations and comprehensive income.
Credit Loss, Financial Instrument [Policy Text Block]	Recently Adopted Accounting Pronouncement In June 2016, the Financial Accounting Standards Board issued ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments." ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit loss" and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. The Partnership adopted ASU 2016-13 on January 1, 2020. The impact of the adoption was not material; however, due to the global economic impacts of COVID-19, the Partnership recorded $16 million of current expected credit losses for the nine months ended September 30, 2020.
