Share-based Payment Arrangement, Noncash Expense [Abstract]
Unit-Based Compensation	Unit-Based Compensation The Partnership has issued phantom units to its employees and non-employee directors, which vest 60% after three years and 40% after five years. Phantom units have the right to receive distributions prior to vesting. The fair value of these units is the market price of our common units on the grant date, and is amortized over the five-year vesting period using the straight-line method. Unit-based compensation expense related to the Partnership included in our Consolidated Statements of Operations and Comprehensive Income (Loss) was $14 million, $13 million and $12 million for the years ended December 31, 2020, 2019 and 2018, respectively. The total fair value of phantom units vested for the years ended December 31, 2020, 2019 and 2018, was $14 million, $14 million and $12 million, respectively, based on the market price of SUN’s common units as of the vesting date. Unrecognized compensation expenses related to our nonvested phantom units totaled $19 million as of December 31, 2020, which are expected to be recognized over a weighted average period of 4.08 years. The fair value of nonvested phantom units outstanding as of December 31, 2020 and December 31, 2019, totaled $62 million and $62 million, respectively. Phantom unit award activity for the years ended December 31, 2020 and 2019 consisted of the following: Number of Phantom Common Units Weighted-Average Grant Date Fair Value Outstanding at December 31, 2018 2,124,012 $ 29.15 Granted 655,630 30.70 Vested (477,256) 30.04 Forfeited (189,064) 28.16 Outstanding at December 31, 2019 2,113,322 29.21 Granted 687,511 28.63 Vested (508,143) 30.47 Forfeited (152,198) 29.11 Outstanding at December 31, 2020 2,140,492 $ 28.63

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 The consolidated financial statements are composed of Sunoco LP, a publicly traded Delaware limited partnership, and our wholly‑owned subsidiaries. We distribute motor fuels across more than 30 states throughout the East Coast, Midwest, South Central and Southeast regions of the United States, from Maine to Florida and from Florida to New Mexico, as well as Hawaii. We also operate retail stores in Hawaii and New Jersey. In January 2018, we sold a portfolio of 1,030 company operated retail fuel outlets, together with ancillary businesses and related assets to 7-Eleven, Inc. ("7-Eleven") and SEI Fuel Services, Inc. ("SEI Fuel") for approximately $3.2 billion (the “7-Eleven Transaction”). The results of the 7-Eleven Transaction have been reported as discontinued operations in the consolidated financial statements. See Note 4 for more information related to the 7-Eleven Purchase Transaction and discontinued operations. All other footnotes present results of the continuing operations. On April 1, 2018, the Partnership completed the conversion of 207 retail sites located in certain West Texas, Oklahoma and New Mexico markets to a single commission agent. 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 impact on gross margin, income from operations, net income (loss) and comprehensive income (loss), or the balance sheets or statements of cash flows.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair Value Measurements We use fair value measurements to measure, among other items, purchased assets, investments, leases and derivative contracts. We also use them to assess impairment of properties, equipment, intangible assets and goodwill. An asset’s fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters, or is derived from such prices or parameters. Where observable prices or inputs are not available, unobservable prices or inputs are used to estimate the current fair value, often using an internal valuation model. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the item being valued. ASC 820 “ Fair Value Measurements and Disclosures ” prioritizes the inputs used in measuring fair value into the following hierarchy: Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; Level 3 Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing. Cash, accounts receivable, certain other current assets, marketable securities, accounts payable, accrued expenses, and certain other current liabilities are reflected in the consolidated balance sheets at carrying amounts, which approximate the fair value due to their short term nature. Segment Reporting We operate our business in two primary operating segments, Fuel Distribution and Marketing and All Other, both of which are included as reportable segments. Our Fuel Distribution and Marketing segment sells motor fuel to our All Other segment and external customers. Our All Other segment includes the Partnership’s credit card services, franchise royalties, and its retail operations in Hawaii and New Jersey. Acquisition Accounting Acquisitions of assets or entities that include inputs and processes and have the ability to create outputs are accounted for as business combinations. A purchase price allocation is recorded for tangible and intangible assets acquired and liabilities assumed based on their fair value. The excess of fair value of consideration conveyed over fair value of net assets acquired is recorded as goodwill. The consolidated statements of operations and comprehensive income (loss) for the periods presented include the results of operations for each acquisition from their respective dates of acquisition. Acquisitions of entities under common control are accounted for similar to a pooling of interests, in which the acquired assets and assumed liabilities are recognized at their historic carrying values. The results of operations of affiliated businesses acquired are reflected in the Partnership’s consolidated results of operations beginning on the date of common control. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits, and short-term investments with original maturities of three months or less. Sunoco LLC and Sunoco Retail have treasury services agreements with Sunoco (R&M), LLC, an indirect wholly-owned subsidiary of ETO, for certain cash management activities. The net balance of Sunoco LLC and Sunoco Retail activity is reflected in either “Advances to affiliates” or “Advances from affiliates” on the consolidated balance sheets. Accounts Receivable The majority of trade receivables are from wholesale fuel customers or from credit card companies related to retail credit card transactions. Wholesale customer credit is extended based on an evaluation of the customer’s financial condition. We maintain allowances for expected credit losses based on the best estimate of the amount of expected credit losses in existing accounts receivable. Credit losses are recorded against the allowance when accounts are deemed uncollectible. Receivables from affiliates arise from fuel sales and other miscellaneous transactions with non-consolidated affiliates. These receivables are recorded at face value, without interest or discount. Inventories Fuel inventories are stated at the lower of cost or market using the last-in-first-out (“LIFO”) method. Under this methodology, the cost of fuel sold consists of actual acquisition costs, which includes transportation and storage costs. Such costs are adjusted to reflect increases or decreases in inventory quantities which are valued based on changes in LIFO inventory layers. Merchandise inventories are stated at the lower of average cost, as determined by the retail inventory method, or market. We record an allowance for shortages and obsolescence relating to merchandise inventory based on historical trends and any known changes. Shipping and handling costs are included in the cost of merchandise inventories. Advertising Costs Advertising costs are expensed as incurred. Advertising costs were $19 million for the year ended December 31, 2020, and $24 million for each of the years ended December 31, 2019 and 2018. Property and Equipment Property and equipment are recorded at cost. Depreciation is computed on a straight-line basis over the useful lives of assets, estimated to be forty years for buildings, three to fifteen years for equipment and thirty years for storage tanks. Assets under finance leases are depreciated over the life of the corresponding lease. Amortization of leasehold improvements is based upon the shorter of the remaining terms of the leases including renewal periods that are reasonably assured, or the estimated useful lives, which approximate twenty years. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Maintenance and repairs are charged to operations as incurred. Gains or losses on the disposition of property and equipment are recorded in the period incurred. Long-Lived Assets and Assets Held for Sale Long-lived assets are tested for possible impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. If such indicators exist, the estimated undiscounted future cash flows related to the asset are compared to the carrying value of the asset. If the carrying value is greater than the estimated undiscounted future cash flow amount, an impairment charge is recorded within loss on disposal of assets and impairment charges in the consolidated statements of operations and comprehensive income (loss) for amounts necessary to reduce the corresponding carrying value of the asset to fair value. The impairment loss calculations require management to apply judgment in estimating future cash flows. Properties that have been closed and other excess real property are recorded as assets held for sale, and are written down to the lower of cost or estimated net realizable value at the time we close such stores or determine that these properties are in excess and intend to offer them for sale. We estimate the net realizable value based on our experience in utilizing or disposing of similar assets and on estimates provided by our own and third-party real estate experts. Although we have not experienced significant changes in our estimate of net realizable value, changes in real estate markets could significantly impact the net values realized from the sale of assets. When we have determined that an asset is more likely than not to be sold in the next twelve months, that asset is classified as assets held for sale and included in other current assets. We had no assets classified as assets held for sale as of December 31, 2020 or 2019. Goodwill and Indefinite-Lived Intangible Assets Goodwill represents the excess of consideration paid over fair value of net assets acquired. Goodwill and intangible assets acquired in a purchase business combination are recorded at fair value as of the date acquired. Acquired intangible assets determined to have an indefinite useful life are not amortized, but are instead tested for impairment at least annually, or more frequently if events and circumstances indicate that the asset might be impaired. The annual impairment test of goodwill and indefinite lived intangible assets is performed as of the first day of the fourth quarter of each fiscal year. The Partnership uses qualitative factors to determine whether it is more likely than not (likelihood of more than 50%) that the fair value of a reporting unit exceeds its carrying amount, including goodwill. Some of the qualitative factors considered in applying this test include consideration of macroeconomic conditions, industry and market conditions, cost factors affecting the business, overall financial performance of the business, and performance of the unit price of the Partnership. If qualitative factors are not deemed sufficient to conclude that the fair value of the reporting unit more likely than not exceeds its carrying value, then a one-step approach is applied in making an evaluation. The evaluation utilizes multiple valuation methodologies, including a market approach (market price multiples of comparable companies) and an income approach (discounted cash flow analysis). The computations require management to make significant estimates and assumptions, including, among other things, selection of comparable publicly traded companies, the discount rate applied to future earnings reflecting a weighted average cost of capital, and earnings growth assumptions. A discounted cash flow analysis requires management to make various assumptions about future sales, operating margins, capital expenditures, working capital, and growth rates. If the evaluation results in the fair value of the reporting unit being lower than the carrying value, an impairment charge is recorded. Indefinite-lived intangible assets are composed of certain tradenames and liquor licenses which are not amortized but are evaluated for impairment annually or more frequently if events or changes occur that suggest an impairment in carrying value, such as a significant adverse change in the business climate. Indefinite-lived intangible assets are evaluated for impairment by comparing each asset’s fair value to its book value. Management first determines qualitatively whether it is more likely than not that an indefinite‑lived asset is impaired. If management concludes that it is more likely than not that an indefinite-lived asset is impaired, then its fair value is determined by using the discounted cash flow model based on future revenues estimated to be derived in the use of the asset. Other Intangible Assets Other finite-lived intangible assets consist of supply agreements, customer relations, non-competes, and loan origination costs. Separable intangible assets that are not determined to have an indefinite life are amortized over their useful lives and assessed for impairment only if and when circumstances warrant. Determination of an intangible asset’s fair value and estimated useful life are based on an analysis of pertinent factors including (1) the use of widely-accepted valuation approaches, such as the income approach or the cost approach, (2) the expected use of the asset by the Partnership, (3) the expected useful life of related assets, (4) any legal, regulatory or contractual provisions, including renewal or extension period that would cause substantial costs or modifications to existing agreements, and (5) the effects of obsolescence, demand, competition, and other economic factors. Should any of the underlying assumptions indicate that the value of the intangible assets might be impaired, we may be required to reduce the carrying value and remaining useful life of the asset. If the underlying assumptions governing the amortization of an intangible asset were later determined to have significantly changed, we may be required to adjust its amortization period to reflect a new estimate of its useful life. Any write‑down of the value or unfavorable change in the useful life of an intangible asset would increase expense at that time. Customer relations and supply agreements are amortized on a straight-line basis over the remaining terms of the agreements, which generally range from five to twenty years. Non-competition agreements are amortized over the terms of the respective agreements, and loan origination costs are amortized over the life of the underlying debt as an increase to interest expense. Asset Retirement Obligations The estimated future cost to remove an underground storage tank is recognized over the estimated useful life of the storage tank. We record a discounted liability for the future fair value of an asset retirement obligation along with a corresponding increase to the carrying value of the related long-lived asset at the time an underground storage tank is installed. We then depreciate the amount added to property and equipment and recognize accretion expense in connection with the discounted liability over the remaining life of the tank. We base our estimates of the anticipated future costs for tank removal on our prior experience with removals. We review assumptions for computing the estimated liability for tank removal on an annual basis. Any change in estimated cash flows are reflected as an adjustment to both the liability and the associated asset. Long-lived assets related to asset retirement obligations aggregated $18 million and $20 million, and were reflected as property and equipment, net on our consolidated balance sheets as of December 31, 2020 and 2019, respectively. Environmental Liabilities Environmental expenditures related to existing conditions, resulting from past or current operations, and from which no current or future benefit is discernible, are expensed. Expenditures that extend the life of the related property or prevent future environmental contamination are capitalized. We determine and establish a liability on a site-by-site basis when it is probable and can be reasonably estimated. A related receivable is recorded for estimable and probable reimbursements. Revenue Recognition Revenue from motor fuel is recognized either at the time fuel is delivered to the customer or at the time of sale. Shipment and delivery of motor fuel generally occurs on the same day. The Partnership charges wholesale customers for third-party transportation costs, which are recorded net in cost of sales. Through PropCo, our wholly-owned corporate subsidiary, we sell motor fuel to customers on a commission agent basis, in which we retain title to inventory, control access to and sale of fuel inventory, and recognize revenue at the time the fuel is sold to the end customer. In our Fuel Distribution and Marketing segment, we derive additional income from lease income, propane and lubricating oils, and other ancillary product and service offerings. In our All Other segment, we derive other income from merchandise, lottery ticket sales, money orders, prepaid phone cards and wireless services, ATM transactions, car washes, and other ancillary product and service offerings. We record revenue from other retail transactions on a net commission basis when a product is sold and/or services are rendered. Lease Income Lease income from operating leases is recognized on a straight-line basis over the term of the lease. Cost of Sales We include in cost of sales all costs incurred to acquire fuel and merchandise, including the costs of purchasing, storing, and transporting inventory prior to delivery to our customers. Items are removed from inventory and are included in cost of sales based on the retail inventory method for merchandise and the LIFO method for motor fuel. Cost of sales does not include depreciation of property and equipment as amounts attributed to cost of sales would not be significant. Depreciation is classified within operating expenses in the consolidated statements of operations and comprehensive income (loss). Motor Fuel and Sales Taxes 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 wholesale direct sales to dealers, distributors and commercial customers is to exclude the collected motor fuel tax from sales and cost of sales. For retail locations where the Partnership holds inventory, including commission agent locations, motor fuel sales and motor fuel cost of sales include motor fuel taxes. Such amounts were $301 million, $386 million and $370 million, for the years ended December 31, 2020, 2019 and 2018, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in the consolidated statements of operations and comprehensive income (loss). Deferred Branding Incentives We receive payments for branding incentives related to fuel supply contracts. Unearned branding incentives are deferred and amortized on a straight-line basis over the term of the agreement as a credit to cost of sales. Lease Accounting At the inception of each lease arrangement, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify lease assets as operating or finance leases under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on the balance sheet. Balances related to operating leases are included in operating lease ROU assets, accrued expenses and other current liabilities, operating lease current liabilities and non-current operating lease liabilities in our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in finance lease ROU assets, current maturities of long-term debt and long-term debt, less current maturities in our consolidated balance sheets. The ROU assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent the obligation of the Partnership to make minimum lease payments arising from the lease for the duration of the lease term. The Partnership leases a portion of its properties under non-cancelable operating leases, whose initial terms are typically five to fifteen years, with options permitting renewal for additional periods. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or greater. The exercise of lease renewal options is typically at the sole discretion of the Partnership and lease extensions are evaluated on a lease-by-lease basis. Leases containing early termination clauses typically require the agreement of both parties to the lease. At the inception of a lease, all renewal options reasonably certain to be exercised are considered when determining the lease term. The depreciable life of lease 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. Presently, because many of our leases do not provide an implicit rate, the Partnership applies its incremental borrowing rate based on the information available at the lease commencement date to determine the present value of minimum lease payments. The operating and finance lease ROU assets include any lease payments made and exclude lease incentives. Minimum rent is expensed on a straight-line basis over the term of the lease, including renewal periods that are reasonably assured at the inception of the lease. The Partnership is typically responsible for payment of real estate taxes, maintenance expenses, and insurance. The Partnership also leases certain vehicles, and such leases are typically less than five years. For short-term leases (leases that have term of twelve months or less upon commencement), lease payments are recognized on a straight-line basis and no ROU assets are recorded. Earnings Per Unit In addition to limited partner units, we have identified incentive distribution rights (“IDRs”) as participating securities and compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the First Amended and Restated Agreement of Limited Partnership, as amended (the “Partnership Agreement”). Net income per unit applicable to limited partners is computed by dividing limited partners’ interest in net income, after deducting any incentive distributions, distributions on Series A Preferred Units and unvested phantom unit awards, by the weighted-average number of outstanding common units. Unit-Based Compensation Under the Partnership's long-term incentive plans, various types of awards may be granted to employees, consultants, and directors of our General Partner who provide services for us. Compensation expense related to outstanding awards is recognized over the vesting period based on the grant-date fair value. The grant-date fair value is determined based on the market price of our common units on the grant date. We amortize the grant-date fair value of these awards over their vesting period using the straight-line method. Expenses related to unit-based compensation are included in general and administrative expenses. Income Taxes The Partnership is a publicly traded limited partnership and is not taxable for federal and most state income tax purposes. As a result, our earnings or losses, to the extent not included in a taxable subsidiary, for federal and most state purposes are included in the tax returns of the individual partners. Net earnings for financial statement purposes may differ significantly from taxable income reportable to Unitholders as a result of differences between the tax basis and financial basis of assets and liabilities, differences between the tax accounting and financial accounting treatment of certain items, and due to allocation requirements related to taxable income under our Partnership Agreement. As a publicly traded limited partnership, we are subject to a statutory requirement that our “qualifying income” (as defined by the Internal Revenue Code, related Treasury Regulations, and IRS pronouncements) exceed 90% of our total gross income, determined on a calendar year basis. If our qualifying income were not to meet this statutory requirement, the Partnership would be taxed as a corporation for federal and state income tax purposes. For the years ended December 31, 2020, 2019, and 2018, our qualifying income met the statutory requirement. The Partnership conducts certain activities through corporate subsidiaries which are subject to federal, state and local income taxes. These corporate subsidiaries include Sunoco Property Company LLC (“PropCo”) and Aloha. The Partnership and its corporate subsidiaries account for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized. The determination of the provision for income taxes requires significant judgment, use of estimates, and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in our financial statements only after determining a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. When facts and circumstances change, we reassess these probabilities and record any changes through the provision for income taxes. 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 $12 million of current expected credit losses for the year ended December 31, 2020.

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations On January 23, 2018, we completed the 7-Eleven Transaction discussed in Note 1. Subsequent to the closing of the 7-Eleven Transaction, previously eliminated wholesale motor fuel sales to the Partnership’s retail locations are reported as wholesale motor fuel sales to third parties. In connection with the 7-Eleven Transaction, we entered into a 15-year take-or-pay fuel supply arrangement with 7-Eleven and SEI Fuel. For the period from January 1, 2018 through January 22, 2018, we recorded sales to the sites that were subsequently sold to 7-Eleven of $199 million, which sales were eliminated in consolidation. The Partnership concluded that it meets the accounting requirements for reporting the financial position, results of operations and cash flows of the 7-Eleven Transaction and the operations of the related assets as discontinued operations. As a result of the 7-Eleven Transaction, the Partnership recorded transaction costs of $3 million during 2018. The Partnership had no assets or liabilities associated with discontinued operations as of December 31, 2020 or 2019. There were no results of operations associated with discontinued operations for the years ended December 31, 2020 or 2019. The results of operations associated with discontinued operations are presented in the following table: Year Ended December 31, 2018 (in millions) Revenues: Motor fuel sales $ 256 Non motor fuel sales (1) 93 Total revenues 349 Cost of sales and operating expenses: Cost of sales 305 General and administrative 7 Other operating 57 Rent 4 Loss on disposal of assets and impairment charge 61 Depreciation, amortization and accretion expense — Total cost of sales and operating expenses 434 Operating loss (85) Interest expense, net (2) Loss on extinguishment of debt and other, net (20) Loss from discontinued operations before income taxes (107) Income tax expense 158 Loss from discontinued operations, net of income taxes $ (265) _______________________________ (1) Non motor fuel sales includes merchandise sales totaling $89 million for the year ended December 31, 2018.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill Goodwill balances and activity for the years ended December 31, 2020 and 2019 consisted of the following: Segment Fuel Distribution and Marketing All Other Consolidated (in millions) Balance at December 31, 2018 $ 1,197 $ 362 $ 1,559 Goodwill adjustments related to previous acquisitions (4) — (4) Balance at December 31, 2019 1,193 362 1,555 Goodwill related to terminal acquisition 9 $ — 9 Balance at December 31, 2020 $ 1,202 $ 362 $ 1,564 During 2018, 2019, and 2020, management performed annual goodwill impairment testing on its reporting units. No goodwill impairment was identified for the reporting units as a result of these tests. During the first quarter of 2020, due to the impacts of the COVID-19 pandemic and the decline in the Partnership’s market capitalization, management determined that interim impairment testing should also be performed. We performed the interim impairment tests consistent with our approach for annual impairment testing, including using similar models, inputs and assumptions. As a result of the interim impairment test, no goodwill impairment was identified for the reporting units. During 2020, $316 million of goodwill from the All Other segment was reclassified to the Fuel Distribution and Marketing segment. The 2018 and 2019 balances were also reclassified by the same amount for presentation purposes. The Partnership determined the fair value of our reporting units using a weighted combination of the discounted cash flow method and the guideline company method. Determining the fair value of a reporting unit requires judgment and the use of significant estimates and assumptions. Such estimates and assumptions include revenue growth rates, operating margins, weighted average costs of capital and future market conditions, among others. The Partnership believes the estimates and assumptions used in our impairment assessments are reasonable and based on available market information, but variations in any of the assumptions could result in materially different calculations of fair value and determinations of whether or not an impairment is indicated. Under the discounted cash flow method, the Partnership determined fair value based on estimated future cash flows of each reporting unit including estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflect the overall level of inherent risk of the reporting unit. Cash flow projections are derived from one year budgeted amounts plus an estimate of later period cash flows, all of which are determined by management. Subsequent period cash flows are developed for each reporting unit using growth rates that management believes are reasonably likely to occur. Under the guideline company method, the Partnership determined the estimated fair value of each of our reporting units by applying valuation multiples of comparable publicly-traded companies to each reporting unit’s projected EBITDA and then averaging that estimate with similar historical calculations using a three year average. In addition, the Partnership estimated a reasonable control premium representing the incremental value that accrues to the majority owner from the opportunity to dictate the strategic and operational actions of the business. Other Intangibles Gross carrying amounts and accumulated amortization for each major class of intangible assets, excluding goodwill, consisted of the following: December 31, 2020 December 31, 2019 Gross Accumulated Net Gross Accumulated Net (in millions) Indefinite-lived Tradenames $ 295 $ — $ 295 $ 295 $ — $ 295 Liquor licenses 12 — 12 12 — 12 Finite-lived Customer relations including supply agreements 569 296 273 580 252 328 Loan origination costs (1) 9 4 5 9 3 6 Other intangibles 9 6 3 10 5 5 Intangible assets, net $ 894 $ 306 $ 588 $ 906 $ 260 $ 646 _______________________________ (1) Loan origination costs are associated with the Revolving Credit Agreement, see Note 10 "Long-Term Debt" for further information. We review amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. If such a review should indicate that the carrying amount of amortizable intangible assets is not recoverable, we reduce the carrying amount of such assets to fair value. We review non-amortizable intangible assets for impairment annually, or more frequently if circumstances dictate. During the fourth quarters of 2018, 2019, and 2020, we performed the annual impairment tests on our indefinite-lived intangible assets. We recognized impairment charges of $30 million on our contractual rights in 2018, primarily due to decreases in projected future revenues and cash flows from the date the intangible asset was originally recorded. No impairments were recorded in 2019 and 2020. Total amortization expense on finite-lived intangibles included in depreciation, amortization and accretion was $57 million, $56 million and $43 million for the years ended December 31, 2020, 2019 and 2018, respectively. Customer relations and supply agreements have a remaining weighted-average life of approximately 9 years. Other intangible assets have a remaining weighted-average life of approximately 8 years. Loan origination costs have a remaining weighted-average life of approximately 3 years. As of December 31, 2020, the Partnership’s estimate of amortization includable in amortization expense and interest expense for each of the five succeeding fiscal years and thereafter for finite-lived intangibles is as follows (in millions): Amortization Interest 2021 $ 53 $ 2 2022 43 2 2023 38 1 2024 28 — 2025 17 — Thereafter 97 — Total $ 276 $ 5

(together with the Partnership, the “Issuers”) completed a private offering of $2.2 billion of senior notes, comprised of $1.0 billion in aggregate principal amount of 4.875% senior notes due 2023 (the “2023 Notes”), $800 million in aggregate principal amount of 5.500% senior notes due 2026 (the “2026 Notes”) and $400 million in aggregate principal amount of 5.875% senior notes due 2028 (the “2028 Notes” and, together with the 2023 Notes and the 2026 Notes, the “Notes”). The terms of the Notes are governed by an indenture dated January 23, 2018, among the Issuers, and certain other subsidiaries of the Partnership (the “Guarantors”) and U.S. Bank National Association, as trustee. The 2023 Notes will mature on January 15, 2023 and interest is payable semi-annually on January 15 and July 15 of each year, commencing July 15, 2018. The 2026 Notes will mature on February 15, 2026 and interest is payable semi-annually on February 15 and August 15 of each year, commencing August 15, 2018. The 2028 Notes will mature on March 15, 2028 and interest is payable semi-annually on March 15 and September 15 of each year, commencing September 15, 2018. The Notes are senior obligations of the Issuers and are guaranteed on a senior basis by all of the Partnership’s existing subsidiaries and certain of its future subsidiaries. The Notes and guarantees are unsecured and rank equally with all of the Issuers’ and each Guarantor’s existing and future senior obligations. The Notes and guarantees are effectively subordinated to the Issuers’ and each Guarantor’s secured obligations, including obligations under the Partnership’s 2018 Revolver (as defined below), to the extent of the value of the collateral securing such obligations, and structurally subordinated to all indebtedness and obligations, including trade payables, of the Partnership’s subsidiaries that do not guarantee the Notes. ETO guarantees collection to the Issuers with respect to the payment of the principal amount of the Notes. ETO is not subject to any of the covenants under the Indenture. In connection with our issuance of the Notes, we entered into a registration rights agreement with the initial purchasers pursuant to which we agreed to complete an offer to exchange the Notes for an issue of registered notes with terms substantively identical to each series of Notes and evidencing the same indebtedness as the Notes on or before January 23, 2019. The exchange offer was completed on December 3, 2018. The Partnership used the proceeds from the private offering, along with proceeds from the 7-Eleven Transaction, to: 1) redeem in full our existing senior notes as of December 31, 2017, comprised of $800 million in aggregate principal amount of 6.250% senior notes due 2021, $600 million in aggregate principal amount of 5.500% senior notes due 2020, and $800 million in aggregate principal amount of 6.375% senior notes due 2023; 2) repay in full and terminate the Term Loan; 3) pay all closing costs in connection with the 7-Eleven Transaction; 4) redeem the outstanding Series A Preferred Units held by ETE for an aggregate redemption amount of approximately $313 million; and 5) repurchase 17,286,859 SUN common units owned by subsidiaries of ETP for aggregate cash consideration of approximately $540 million. On December 9, 2020 approximately 56% of the aggregate principal amount of outstanding 2023 Notes were tendered. The tender of the 2023 Notes was funded from the proceeds of the 2020 private offering disclosed below. On January 15, 2021, we repurchased the remaining outstanding portion of our 2023 Notes. 2019 Private Offering of Senior Notes On March 14, 2019, we, our General Partner and Sunoco Finance Corp. (together with the Partnership, the “2027 Notes Issuers”) completed a private offering of $600 million in aggregate principal amount of 6.000% senior notes due 2027 (the “2027 Notes”). The terms of the 2027 Notes are governed by an indenture dated March 14, 2019, among the 2027 Notes Issuers, certain subsidiaries of the Partnership (the “2027 Notes Guarantors”) and U.S. Bank National Association, as trustee. The 2027 Notes will mature on April 15, 2027, and interest on the 2027 Notes is payable semi-annually on April 15 and October 15 of each year, commencing October 15, 2019. The 2027 Notes are senior obligations of the 2027 Notes Issuers and are guaranteed on a senior basis by all of the Partnership’s current subsidiaries (other than Sunoco Finance Corp.) that guarantee its obligations under the 2018 Revolver (as defined below) and certain of its future subsidiaries. The 2027 Notes and guarantees are unsecured and rank equally with all of the 2027 Notes Issuers’ and each 2027 Notes Guarantor’s existing and future senior obligations. The 2027 Notes and guarantees are effectively subordinated to the 2027 Notes Issuers’ and each 2027 Notes Guarantor’s secured obligations, including obligations under the 2018 Revolver (as defined below), to the extent of the value of the collateral securing such obligations, and structurally subordinated to all indebtedness and obligations, including trade payables, of the Partnership’s subsidiaries that do not guarantee the 2027 Notes.

The exchange offer was completed on July 17, 2019. The Partnership used the proceeds from the private offering to repay a portion of the outstanding borrowings under our 2018 Revolver (as defined below). 2020 Private Offering of Senior Notes On November 9, 2020, we, our General Partner and Sunoco Finance Corp. (together with the Partnership, the “2029 Notes Issuers”) completed a private offering of $800 million in aggregate principal amount of 4.500% senior notes due 2029 (the “2029 Notes”). The terms of the 2029 Notes are governed by an indenture dated November 9, 2020, among the 2029 Notes Issuers, certain subsidiaries of the Partnership (the “2029 Notes Guarantors”) and U.S. Bank National Association, as trustee. The 2029 Notes will mature on May 15, 2029, and interest on the 2029 Notes is payable semi-annually on May 15 and November 15 of each year, commencing May 15, 2021. The 2029 Notes are senior obligations of the 2029 Notes Issuers and are guaranteed on a senior basis by all of the Partnership’s current subsidiaries (other than Sunoco Finance Corp.) that guarantee its obligations under the 2018 Revolver (as defined below) and certain of its future subsidiaries. The 2029 Notes and guarantees are unsecured and rank equally with all of the 2029 Notes Issuers’ and each 2029 Notes Guarantor’s existing and future senior obligations. The 2029 Notes and guarantees are effectively subordinated to the 2029 Notes Issuers’ and each 2029 Notes Guarantor’s secured obligations, including obligations under the 2018 Revolver (as defined below), to the extent of the value of the collateral securing such obligations, and structurally subordinated to all indebtedness and obligations, including trade payables, of the Partnership’s subsidiaries that do not guarantee the 2029 Notes. In connection with our issuance of the 2029 Notes, we entered into a registration rights agreement with the initial purchasers pursuant to which we agreed to complete an offer to exchange the 2029 Notes for an issue of registered notes with terms substantively identical to the 2029 Notes and evidencing the same indebtedness as the 2029 Notes on or before November 9, 2021. The Partnership used the proceeds from the private offering to fund the repurchase of a portion of the 2023 Notes and to repay the outstanding balance on the 2018 Revolver. Revolving Credit Agreement On July 27, 2018, we entered into a new Amended and Restated Credit Agreement among the Partnership, as borrower, the lenders from time to time party thereto and Bank of America, N.A., as administrative agent, collateral agent, swingline lender and a line of credit issuer (the “2018 Revolver”). Borrowings under the 2018 Revolver were used to pay off the Partnership’s existing revolving credit facility entered into on September 25, 2014. The 2018 Revolver is a $1.50 billion revolving credit facility, expiring July 27, 2023 (which date may be extended in accordance with the terms of the 2018 Revolver). The facility can be increased from time to time upon the Partnership’s written request, subject to certain conditions, up to an additional $750 million. Borrowings under the revolving credit facility will bear interest at a base rate (a rate based off of the higher of (a) the Federal Funds Rate (as defined in the 2018 Revolver) plus 0.5%, (b) Bank of America’s prime rate and (c) one-month LIBOR (as defined therein) plus 1.00%) or LIBOR, in each case plus an applicable margin ranging from 1.25% to 2.25%, in the case of a LIBOR loan, or from 0.250% to 1.25%, in the case of a base rate loan (determined with reference to the Partnership’s Net Leverage Ratio as defined in the 2018 Revolver). Upon the first achievement by the Partnership of an investment grade credit rating, the applicable margin will decrease to a range of 1.125% to 1.75%, in the case of a LIBOR loan, or from 0.125% to 0.750%, in the case of a base rate loan (determined with reference to the credit rating for the Partnership’s senior, unsecured, non-credit enhanced long-term debt and the Partnership’s corporate issuer rating). Interest is payable quarterly if the base rate applies, at the end of the applicable interest period if LIBOR applies and at the end of the month if daily floating LIBOR applies. In addition, the unused portion of the Partnership’s revolving credit facility will be subject to a commitment fee ranging from 0.250% to 0.350%, based on the Partnership’s Leverage Ratio. Upon the first achievement by the Partnership of an investment grade credit rating, the commitment fee will decrease to a range of 0.125% to 0.350%, based on the Partnership’s credit rating as described above. The 2018 Revolver requires the Partnership to maintain a Net Leverage Ratio of not more than 5.50 to 1.00. The maximum Net Leverage Ratio is subject to upwards adjustment of not more than 6.00 to 1.00 for a period not to exceed three fiscal quarters in the event the Partnership engages in certain specified acquisitions of not less than $50 million (as permitted under the 2018 Revolver). The 2018 Revolver also requires the Partnership to maintain an Interest Coverage Ratio (as defined in the 2018 Revolver) of not less than 2.25 to 1.00. Indebtedness under the 2018 Revolver is secured by a security interest in, among other things, all of the Partnership’s present and future personal property and all of the present and future personal property of its guarantors, the capital stock of its material subsidiaries (or 66% of the capital stock of material foreign subsidiaries), and any intercompany debt. Upon the first achievement by the Partnership of an investment grade credit rating, all security interests securing the 2018 Revolver will be released. As of December 31, 2020, the 2018 Revolver had no outstanding borrowings, and $8 million in standby letters of credit were outstanding. The unused availability on the 2018 Revolver at December 31, 2020 was $1.5 billion. The weighted average interest rate on the total amount outstanding at December 31, 2020 was 0.00%. The Partnership was in compliance with all financial covenants at December 31, 2020. Sale Leaseback Financing Obligation On April 4, 2013, Southside Oil, LLC (“Southside”), a subsidiary of the Partnership, completed a sale leaseback transaction with two separate companies for 50 of its dealer operated sites. As Southside did not meet the criteria for sale leaseback accounting, this transaction was accounted for as a financing arrangement over the course of the lease agreement. The obligations mature in varying dates through 2033, require monthly interest and principal payments, and bear interest at 5.125%. The obligation related to this transaction is included in current and long-term debt and the balance outstanding as of December 31, 2020 was $97 million. Fair Value of Debt The estimated fair value of debt is calculated using Level 2 inputs. The fair value of debt as of December 31, 2020, is estimated to be approximately $3.3 billion, based on outstanding balances as of the end of the period using current interest rates for similar securities.

Revenue from Contract with Customer [Abstract]
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: Year Ended December 31, 2020 2019 2018 (in millions) Fuel Distribution and Marketing Segment Dealer $ 2,211 $ 3,542 $ 3,639 Distributor 4,838 7,645 7,873 Unbranded Wholesale 1,831 2,729 2,577 Commission Agent 1,050 1,606 1,377 Non motor fuel sales 54 62 48 Lease income 127 131 118 Total 10,111 15,715 15,632 All Other Segment Motor fuel 402 654 1,038 Non motor fuel sales 186 216 312 Lease income 11 11 12 Total 599 881 1,362 Total Revenue $ 10,710 $ 16,596 $ 16,994 Fuel Distribution and Marketing Revenue The Partnership’s Fuel Distribution and Marketing operations earn revenue from the following channels: sales to Dealers, sales to Distributors, Unbranded Wholesale revenue, Commission Agent revenue, Non motor fuel sales, and Lease income. Motor fuel revenue consists primarily of the sale of motor fuel under supply agreements with third-party customers and affiliates. Fuel supply contracts with our customers generally provide that we distribute motor fuel at a formula price based on published rates, volume-based profit margin, and other terms specific to the agreement. The customer is invoiced the agreed-upon price with most payment terms ranging less than 30 days. If the consideration promised in a contract includes a variable amount, the Partnership estimates the variable consideration amount and factors in such an estimate to determine the transaction price under the expected value method. Revenue is recognized under the motor fuel contracts at the point in time the customer takes control of the fuel. At the time control is transferred to the customer the sale is considered final, because the agreements do not grant customers the right to return motor fuel. Under the new standard, to determine when control transfers to the customer, the shipping terms of the contract are assessed as shipping terms are considered a primary indicator of the transfer of control. For FOB shipping point terms, revenue is recognized at the time of shipment. The performance obligation with respect to the sale of goods is satisfied at the time of shipment since the customer gains control at this time under the terms. Shipping and/or handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs. Once the goods are shipped, the Partnership is precluded from redirecting the shipment to another customer and revenue is recognized. Commission agent revenue consists of sales from commission agent agreements between the Partnership and select operators. The Partnership supplies motor fuel to sites operated by commission agents and sells the fuel directly to the end customer. In commission agent arrangements, control of the product is transferred at the point in time when the goods are sold to the end customer. To reflect the transfer of control, the Partnership recognizes commission agent revenue at the point in time fuel is sold to the end customer. The Partnership receives lease income from leased or subleased properties. Revenues from leasing arrangements for which we are the lessor are recognized ratably over the term of the underlying lease. All Other Revenue The Partnership’s All Other operations earn revenue from the following channels: Motor fuel sales, Non motor fuel sales, and Lease income. Motor fuel sales consist of fuel sales to consumers at company-operated retail stores. Non motor fuel sales includes merchandise revenue that comprises the in-store merchandise and foodservice sales at company-operated retail stores, and other revenue that represents a variety of other services within our All Other segment including credit card processing, car washes, lottery, automated teller machines, money orders, prepaid phone cards and wireless services. Revenue from All Other operations is recognized when (or as) the performance obligations are satisfied (i.e. when the customer obtains control of the good or the service is provided). Contract Balances with Customers The Partnership satisfies its obligations by transferring goods or services in exchange for consideration from customers. The timing of performance may differ from the timing the associated consideration is paid to or received from the customer, thus resulting in the recognition of a contract asset or a contract liability. The Partnership recognizes a contract asset when making upfront consideration payments to certain customers. The upfront considerations represent a pre-paid incentive, as these payments are not made for distinct goods or services provided by the customer. The pre-payment incentives are recognized as a contract asset upon payment and amortized as a reduction of revenue over the term of the specific agreement. The Partnership recognizes a contract liability if the customer’s payment of consideration precedes the Partnership’s fulfillment of the performance obligations. We maintain some franchise agreements requiring dealers to make one-time upfront payments for long-term license agreements. The Partnership recognizes a contract liability when the upfront payment is received and recognizes revenue over the term of the license. The balances of the Partnership’s contract assets and contract liabilities as of December 31, 2020 and 2019 are as follows: December 31, 2020 December 31, 2019 Increase/ (Decrease) (in millions) Contract Balances Contract Asset $ 121 $ 117 $ 4 Accounts receivable from contracts with customers $ 256 $ 366 $ (110) Contract Liability $ — $ — $ — The amount of revenue recognized in the years ended December 31, 2020, 2019, and 2018 that was included in the contract liability balance at the beginning of each period was $0.2 million, $0.4 million, and $0.6 million, 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. Performance Obligations At contract inception, the Partnership assesses the goods and services promised in its contracts with customers and identifies a performance obligation for each promise to transfer a good or service (or bundle of goods or services) that is distinct. To identify the performance obligations, the Partnership considers all the goods or services promised in the contract, whether explicitly stated or implied based on customary business practices. For a contract that has more than one performance obligation, the Partnership allocates the total contract consideration to each distinct performance obligation on a relative standalone selling price basis. Revenue is recognized when (or as) the performance obligations are satisfied, that is, when the customer obtains control of the good or the service is provided. The Partnership distributes fuel under long-term contracts to branded distributors, branded and unbranded third-party dealers, and branded and unbranded retail fuel outlets. Sunoco-branded supply contracts with distributors generally have both time and volume commitments that establish contract duration. These contracts have an initial term of approximately ten years, with an estimated, volume-weighted term remaining of approximately four years. As part of the 7-Eleven Transaction, the Partnership and 7-Eleven and SEI Fuel (collectively, the “Distributor”) have entered into a 15-year take-or-pay fuel supply agreement in which the Distributor is required to purchase a volume of fuel that provides the Partnership a minimum amount of gross profit annually. We expect to recognize this revenue in accordance with the contract as we transfer control of the product to the customer. However, in case of annual shortfall we will recognize the amount payable by the Distributor at the sooner of the time at which the Distributor makes up the shortfall or becomes contractually or operationally unable to do so. The transaction price of the contract is variable in nature, fluctuating based on market conditions. The Partnership has elected to take the practical expedient not to estimate the amount of variable consideration allocated to wholly unsatisfied performance obligations. 7-Eleven is the only third-party dealer or distributor which is individually over 10% of our Fuel Distribution and Marketing segment or individually over 10%, in terms of revenue, of our aggregate business. In some contractual arrangements, the Partnership grants dealers a franchise license to operate the Partnership’s retail stores over the life of a franchise agreement. In return for the grant of the retail store license, the dealer makes a one-time nonrefundable franchise fee payment to the Partnership plus sales based royalties payable to the Partnership at a contractual rate during the period of the franchise agreement. Under the requirements of ASC Topic 606, the franchise license is deemed to be a symbolic license for which recognition of revenue over time is the most appropriate measure of progress toward complete satisfaction of the performance obligation. Revenue from this symbolic license is recognized evenly over the life of the franchise agreement. 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 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 in the years ended December 31, 2020, 2019, and 2018 was $18 million, $17 million, and $14 million, respectively. The Partnership has also made a policy election of expensing the costs to obtain a contract, as and when they are incurred, in cases where the expected amortization period is one year or less. Practical Expedients Selected by the Partnership The Partnership elected the following practical expedients in accordance with ASC 606: • Significant financing component - The Partnership elected not to adjust the promised amount of consideration for the effects of significant financing component if the Partnership expects at contract inception that the period between the transfer of a promised good or service to a customer and when the customer pays for that good or service will be one year or less. • Incremental costs of obtaining a contract - The Partnership generally expenses sales commissions when incurred because the amortization period would have been less than one year. We record these costs within general and administrative expenses. The Partnership elected to expense the incremental costs of obtaining a contract when the amortization period for such contracts would have been one year or less. • Shipping and handling costs - The Partnership elected to account for shipping and handling activities that occur after the customer has obtained control of a good as fulfillment activities (i.e., an expense) rather than as a promised service. • Measurement of transaction price - The Partnership has elected to exclude from the measurement of transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Partnership from a customer (i.e., sales tax, value added tax, etc.). • Variable consideration of wholly unsatisfied performance obligations - The Partnership has elected to exclude the estimate of variable consideration to the allocation of wholly unsatisfied performance obligations.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies 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 under Topic 842. 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 under the new standard. Operating leases are included in lease right-of-use (“ROU”) assets, operating lease current liabilities, and operating lease non-current liabilities in our consolidated balance sheet. 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 sheet. 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 year 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 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.

Our lessor and sublease portfolio consists mainly of operating leases with convenience store operators. At this time, most lessor agreements contain 5-year terms with renewal options to extend and early termination options based on established terms specific to the individual agreement.

In the ordinary course of business, we are sometimes threatened with or named as a defendant in various lawsuits seeking actual and punitive damages for personal injury and property damage. We maintain liability insurance with insurers in amounts and with coverage and deductibles management believes are reasonable and prudent, and which are generally accepted in the industry. However, there can be no assurance that the levels of insurance protection currently in effect will continue to be available at reasonable prices or that such levels will remain adequate to protect us from material expenses related to personal injury or property damage in the future. In addition, various regulatory agencies such as tax authorities, environmental agencies, or other such agencies may perform audits or reviews to ensure proper compliance with regulations. We are not fully-insured for any claims that may arise from these various agencies and there can be no assurance that any claims arising from these activities would not have an adverse, material effect on our financial statements. Environmental Remediation We are subject to various federal, state and local environmental laws and make financial expenditures in order to comply with regulations governing underground storage tanks adopted by federal, state and local regulatory agencies. In particular, at the federal level, the Resource Conservation and Recovery Act of 1976, as amended, requires the EPA to establish a comprehensive regulatory program for the detection, prevention, and cleanup of leaking underground storage tanks (e.g. overfills, spills, and underground storage tank releases). Federal and state regulations require us to provide and maintain evidence that we are taking financial responsibility for corrective action and compensating third parties in the event of a release from our underground storage tank systems and terminals. In order to comply with these requirements, we have historically obtained private insurance in the states in which we operate. These policies provide protection from third-party liability claims. During 2020, our coverage was $10 million per occurrence and in the aggregate. Our sites continue to be covered by these policies. We are currently involved in the investigation and remediation of contamination at motor fuel storage and gasoline store sites where releases of regulated substances have been detected. We accrue for anticipated future costs and the related probable state reimbursement amounts for remediation activities. Accordingly, we have recorded estimated undiscounted liabilities for these sites totaling $20 million and $29 million as of December 31, 2020 and 2019, respectively, which are classified as accrued expenses and other current liabilities and other noncurrent liabilities. As of December 31, 2020, we had $0.76 million in an escrow account to satisfy environmental claims related to the acquisition of Mid-Atlantic Convenience Stores, LLC.

Income Tax Disclosure [Abstract]
Income Tax	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. The components of the federal and state income tax expense (benefit) are summarized as follows: Year Ended December 31, 2020 2019 2018 (in millions) Current: Federal $ 18 $ 7 $ 24 State 1 (30) 4 Total current income tax expense (benefit) 19 (23) 28 Deferred: Federal 1 2 (14) State 4 4 20 Total deferred tax expense (benefit) 5 6 6 Net income tax expense (benefit) $ 24 $ (17) $ 34 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 at the U.S. federal statutory rate to net income tax expense (benefit) is as follows: Year Ended December 31, 2020 2019 2018 (in millions) Tax at statutory federal rate $ 50 $ 62 $ 19 Partnership earnings not subject to tax (34) (62) (9) Goodwill impairment — — — State and local tax, including federal expense (benefit) 3 (17) 24 Other 5 — — Net income tax expense (benefit) $ 24 $ (17) $ 34 In 2019, a current state income tax benefit (including federal benefit) of $17 million was largely attributable to a change in estimate related to state income taxes. Deferred taxes result from the temporary differences between financial reporting carrying amounts and the tax basis of existing assets and liabilities. Principal components of deferred tax assets and liabilities are as follows: December 31, 2020 December 31, 2019 (in millions) Deferred tax assets: Net operating and other loss carry forwards $ 4 $ 4 Other 20 32 Total deferred tax assets 24 36 Deferred tax liabilities: Property and equipment 18 24 Trademarks and other intangibles 77 72 Investments in affiliates 33 39 Other — 10 Total deferred tax liabilities 128 145 Net deferred income tax liabilities $ 104 $ 109 As of December 31, 2020, Sunoco Property Company LLC, a corporate subsidiary of Sunoco LP, had a state net operating loss carryforward of $121 million, which we expect to fully utilize. Sunoco Property Company LLC has no federal net operating loss carryforward. The following table sets forth the changes in unrecognized tax benefits: Year Ended December 31, 2020 2019 2018 (in millions) Balance at beginning of year $ 11 $ — $ — Additions attributable to tax positions taken in the current year — — — Additions attributable to tax positions taken in prior years — 11 — Reduction attributable to tax positions taken in prior years — — — Lapse of statute — — — Balance at end of year $ 11 $ 11 $ — As of December 31, 2020, we had $11 million ($8 million after federal income tax benefits) related to tax positions which, if recognized, would impact our effective tax rate. Our policy is to accrue interest and penalties on income tax underpayments (overpayments) as a component of income tax expense. During 2020, we recognized interest and penalties of $1 million. At December 31, 2020, we had interest and penalties accrued of $1 million, net of taxes.

LLC, MUFG Securities Americas Inc., Natixis Securities Americas LLC, SMBC Nikko Securities America, Inc., TD Securities (USA) LLC, UBS Securities LLC and Wells Fargo Securities, LLC (collectively, the “Managers”). As of December 31, 2020, $295 million of our common units remained available to be issued under the equity distribution agreement. Common unit activity for the years ended December 31, 2020 and 2019 was as follows: Number of Units Number of common units at December 31, 2018 82,665,057 Phantom unit vesting 320,884 Number of common units at December 31, 2019 82,985,941 Phantom unit vesting 347,690 Number of common units at December 31, 2020 83,333,631 Allocation of Net Income Our Partnership Agreement contains provisions for the allocation of net income and loss to the unitholders. 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, if any, to priority income allocations in an amount equal to incentive cash distributions allocated 100% to ETO. The calculation of net income allocated to the partners is as follows (in millions, except per unit amounts): Year Ended December 31, 2020 2019 2018 Attributable to Common Units Distributions (a) $ 274 $ 273 $ 272 Distributions in excess of net income (139) (38) (557) Limited partners’ interest in net income (loss) $ 135 $ 235 $ (285) (a) Distributions declared per unit to unitholders as of record date $ 3.3020 $ 3.3020 $ 3.3020 Class C Units The Partnership has outstanding an aggregate of 16,410,780 Class C Units, all of which are held by wholly-owned subsidiaries of the Partnership. Class C Units (i) are not convertible or exchangeable into Common Units or any other units of the Partnership and are non-redeemable; (ii) are entitled to receive distributions of available cash of the Partnership (other than available cash derived from or attributable to any distribution received by the Partnership from PropCo, the proceeds of any sale of the membership interests of PropCo, or any interest or principal payments received by the Partnership with respect to indebtedness of PropCo or its subsidiaries) at a fixed rate equal to $0.8682 per quarter for each Class C Unit outstanding, (iii) do not have the right to vote on any matter except as otherwise required by any non-waivable provision of law, (iv) are not allocated any items of income, gain, loss, deduction or credit attributable to the Partnership’s ownership of, or sale or other disposition of, the membership interests of PropCo, or the Partnership’s ownership of any indebtedness of PropCo or any of its subsidiaries (“PropCo Items”), (v) will be allocated gross income (other than from PropCo Items) in an amount equal to the cash distributed to the holders of Class C Units and (vi) will be allocated depreciation, amortization and cost recovery deductions as if the Class C Units were Common Units and 1% of certain allocations of net termination gain (other than from PropCo Items). Pursuant to the terms described above, these distributions do not have an impact on the Partnership’s consolidated cash flows and as such, are excluded from total cash distributions and allocation of limited partners’ interest in net income. Incentive Distribution Rights The following table illustrates the percentage allocations of available cash from operating surplus between our common unitholders and the holder of our IDRs based on the specified target distribution levels, after the payment of distributions to Class C unitholders. The amounts set forth under “marginal percentage interest in distributions” are the percentage interests of our IDR holder and the common unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “total quarterly distribution per common unit target amount.” The percentage interests shown for our common unitholders and our IDR holder for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. ETO currently owns our IDRs. Marginal percentage interest in distributions Total quarterly distribution per Common unit Common Holder of IDRs Minimum Quarterly Distribution $0.4375 100 % — First Target Distribution Above $0.4375 up to $0.503125 100 % — Second Target Distribution Above $0.503125 up to $0.546875 85 % 15 % Third Target Distribution Above $0.546875 up to $0.656250 75 % 25 % Thereafter Above $0.656250 50 % 50 % Cash Distributions Our Partnership Agreement sets forth the calculation used to determine the amount and priority of cash distributions that the common unitholders receive. Cash distributions paid were as follows: Limited Partners Payment Date Per Unit Distribution Total Cash Distribution Distribution to IDR Holders (in millions, except per unit amounts) February 19, 2021 $ 0.8255 $ 69 $ 18 November 19, 2020 $ 0.8255 $ 69 $ 18 August 19, 2020 $ 0.8255 $ 69 $ 18 May 19, 2020 $ 0.8255 $ 69 $ 18 February 19, 2020 $ 0.8255 $ 69 $ 18 November 19, 2019 $ 0.8255 $ 68 $ 18 August 14, 2019 $ 0.8255 $ 68 $ 18 May 15, 2019 $ 0.8255 $ 68 $ 18 February 14, 2019 $ 0.8255 $ 68 $ 18 November 14, 2018 $ 0.8255 $ 68 $ 18 August 15, 2018 $ 0.8255 $ 68 $ 17 May 15, 2018 $ 0.8255 $ 68 $ 18 February 14, 2018 $ 0.8255 $ 82 $ 21 In January 2018, the Partnership paid a $10 million cash distribution on its previously outstanding Series A Preferred Units, which included an $8 million cash distribution for the three months ended December 31, 2017 and a $2 million cash distribution for the period from January 1, 2018 through January 25, 2018.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Our financial statements reflect two reportable segments, Fuel Distribution and Marketing and All Other. After the Retail Divestment and the conversion of 207 retail sites to commission agent sites, the Partnership renamed the former Wholesale segment to Fuel Distribution and Marketing and the former Retail segment to 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, depreciation, amortization and accretion expense, non-cash 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. Fuel Distribution and Marketing Segment Our Fuel Distribution and Marketing segment purchases motor fuel primarily from independent refiners and major oil companies and supplies it to independently-operated dealer stations under long-term supply agreements, distributors and other consumers of motor fuel, and Partnership-operated stations included in our All Other segment. Also included in the Fuel Distribution and Marketing segment are motor fuel sales to commission agent locations and sales and costs related to processing transmix. We distribute motor fuels across more than 30 states throughout the East Coast, Midwest, South Central and Southeast regions of the United States from Maine to Florida and from Florida to New Mexico, as well as Hawaii. Sales of fuel from our Fuel Distribution and Marketing segment to Partnership-operated stations included in our All Other segment are delivered at cost plus a profit margin. These amounts are included in intercompany eliminations of motor fuel revenue and motor fuel cost of sales. Also included in our Fuel Distribution and Marketing segment is lease income from properties that we lease or sublease. All Other Segment The operations related to assets associated with the 7-Eleven Transaction are included in discontinued operations in the following segment information. Subsequent to the completion of the 7-Eleven Transaction, the remaining All Other segment includes the Partnership’s credit card services, franchise royalties, and retail operations in Hawaii and New Jersey. The following tables present financial information by segment for the years ended December 31, 2020, 2019 and 2018.

Net Income per Unit

Net Income per Unit	12 Months Ended
	Dec. 31, 2020
Earnings Per Share [Abstract]
Net Income per Unit	Net Income per Unit Net income per unit applicable to limited partners is computed by dividing limited partners’ interest in net income by the weighted‑average number of outstanding common units. Our net income is allocated to limited partners in accordance with their respective partnership percentages, after giving effect to any priority income allocations for incentive distributions and distributions on employee unit awards. Earnings in excess of distributions are allocated to limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit. In addition to the common units, we identify the IDRs as participating securities and use the two-class method when calculating net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Diluted net income per unit includes the effects of potentially dilutive units on our common units, consisting of unvested phantom units. A reconciliation of the numerators and denominators of the basic and diluted per unit computations is as follows: Year Ended December 31, 2020 2019 2018 (in millions, except units and per unit amounts) Income from continuing operations $ 212 $ 313 $ 58 Less: Series A Preferred units — — 2 Incentive distribution rights 71 72 70 Distributions on nonvested phantom unit awards 6 6 6 Limited partners’ interest in net income (loss) from continuing operations $ 135 $ 235 $ (20) Loss from discontinued operations, net of taxes $ — $ — $ (265) Weighted average limited partner units outstanding: Common - basic 83,062,159 82,755,520 84,299,893 Common - equivalents 654,305 796,442 520,677 Common - diluted 83,716,464 83,551,962 84,820,570 Income (loss) from continuing operations per limited partner unit: Common - basic $ 1.63 $ 2.84 $ (0.25) Common - diluted $ 1.61 $ 2.82 $ (0.25) Loss from discontinued operations per limited partner unit: Common - basic $ — $ — $ (3.14) Common - diluted $ — $ — $ (3.14)

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Measurements	Fair Value Measurements We use fair value measurements to measure, among other items, purchased assets, investments, leases and derivative contracts. We also use them to assess impairment of properties, equipment, intangible assets and goodwill. An asset’s fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters, or is derived from such prices or parameters. Where observable prices or inputs are not available, unobservable prices or inputs are used to estimate the current fair value, often using an internal valuation model. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the item being valued. ASC 820 “ Fair Value Measurements and Disclosures ” prioritizes the inputs used in measuring fair value into the following hierarchy: Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; Level 3 Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing. Cash, accounts receivable, certain other current assets, marketable securities, accounts payable, accrued expenses, and certain other current liabilities are reflected in the consolidated balance sheets at carrying amounts, which approximate the fair value due to their short term nature.
Segment Reporting	Segment ReportingWe operate our business in two primary operating segments, Fuel Distribution and Marketing and All Other, both of which are included as reportable segments. Our Fuel Distribution and Marketing segment sells motor fuel to our All Other segment and external customers. Our All Other segment includes the Partnership’s credit card services, franchise royalties, and its retail operations in Hawaii and New Jersey.
Acquisition Accounting	Acquisition Accounting Acquisitions of assets or entities that include inputs and processes and have the ability to create outputs are accounted for as business combinations. A purchase price allocation is recorded for tangible and intangible assets acquired and liabilities assumed based on their fair value. The excess of fair value of consideration conveyed over fair value of net assets acquired is recorded as goodwill. The consolidated statements of operations and comprehensive income (loss) for the periods presented include the results of operations for each acquisition from their respective dates of acquisition. Acquisitions of entities under common control are accounted for similar to a pooling of interests, in which the acquired assets and assumed liabilities are recognized at their historic carrying values. The results of operations of affiliated businesses acquired are reflected in the Partnership’s consolidated results of operations beginning on the date of common control.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits, and short-term investments with original maturities of three months or less. Sunoco LLC and Sunoco Retail have treasury services agreements with Sunoco (R&M), LLC, an indirect wholly-owned subsidiary of ETO, for certain cash management activities. The net balance of Sunoco LLC and Sunoco Retail activity is reflected in either “Advances to affiliates” or “Advances from affiliates” on the consolidated balance sheets.
Accounts Receivable	Accounts Receivable The majority of trade receivables are from wholesale fuel customers or from credit card companies related to retail credit card transactions. Wholesale customer credit is extended based on an evaluation of the customer’s financial condition. We maintain allowances for expected credit losses based on the best estimate of the amount of expected credit losses in existing accounts receivable. Credit losses are recorded against the allowance when accounts are deemed uncollectible. Receivables from affiliates arise from fuel sales and other miscellaneous transactions with non-consolidated affiliates. These receivables are recorded at face value, without interest or discount.
Inventories	Inventories Fuel inventories are stated at the lower of cost or market using the last-in-first-out (“LIFO”) method. Under this methodology, the cost of fuel sold consists of actual acquisition costs, which includes transportation and storage costs. Such costs are adjusted to reflect increases or decreases in inventory quantities which are valued based on changes in LIFO inventory layers. Merchandise inventories are stated at the lower of average cost, as determined by the retail inventory method, or market. We record an allowance for shortages and obsolescence relating to merchandise inventory based on historical trends and any known changes. Shipping and handling costs are included in the cost of merchandise inventories.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred. Advertising costs were $19 million for the year ended December 31, 2020, and $24 million for each of the years ended December 31, 2019 and 2018.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost. Depreciation is computed on a straight-line basis over the useful lives of assets, estimated to be forty years for buildings, three to fifteen years for equipment and thirty years for storage tanks. Assets under finance leases are depreciated over the life of the corresponding lease. Amortization of leasehold improvements is based upon the shorter of the remaining terms of the leases including renewal periods that are reasonably assured, or the estimated useful lives, which approximate twenty years. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Maintenance and repairs are charged to operations as incurred. Gains or losses on the disposition of property and equipment are recorded in the period incurred.
Long-Lived Assets and Assets Held for Sale	Long-Lived Assets and Assets Held for Sale Long-lived assets are tested for possible impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. If such indicators exist, the estimated undiscounted future cash flows related to the asset are compared to the carrying value of the asset. If the carrying value is greater than the estimated undiscounted future cash flow amount, an impairment charge is recorded within loss on disposal of assets and impairment charges in the consolidated statements of operations and comprehensive income (loss) for amounts necessary to reduce the corresponding carrying value of the asset to fair value. The impairment loss calculations require management to apply judgment in estimating future cash flows. Properties that have been closed and other excess real property are recorded as assets held for sale, and are written down to the lower of cost or estimated net realizable value at the time we close such stores or determine that these properties are in excess and intend to offer them for sale. We estimate the net realizable value based on our experience in utilizing or disposing of similar assets and on estimates provided by our own and third-party real estate experts. Although we have not experienced significant changes in our estimate of net realizable value, changes in real estate markets could significantly impact the net values realized from the sale of assets. When we have determined that an asset is more likely than not to be sold in the next twelve months, that asset is classified as assets held for sale and included in other current assets. We had no assets classified as assets held for sale as of December 31, 2020 or 2019.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets Goodwill represents the excess of consideration paid over fair value of net assets acquired. Goodwill and intangible assets acquired in a purchase business combination are recorded at fair value as of the date acquired. Acquired intangible assets determined to have an indefinite useful life are not amortized, but are instead tested for impairment at least annually, or more frequently if events and circumstances indicate that the asset might be impaired. The annual impairment test of goodwill and indefinite lived intangible assets is performed as of the first day of the fourth quarter of each fiscal year. The Partnership uses qualitative factors to determine whether it is more likely than not (likelihood of more than 50%) that the fair value of a reporting unit exceeds its carrying amount, including goodwill. Some of the qualitative factors considered in applying this test include consideration of macroeconomic conditions, industry and market conditions, cost factors affecting the business, overall financial performance of the business, and performance of the unit price of the Partnership. If qualitative factors are not deemed sufficient to conclude that the fair value of the reporting unit more likely than not exceeds its carrying value, then a one-step approach is applied in making an evaluation. The evaluation utilizes multiple valuation methodologies, including a market approach (market price multiples of comparable companies) and an income approach (discounted cash flow analysis). The computations require management to make significant estimates and assumptions, including, among other things, selection of comparable publicly traded companies, the discount rate applied to future earnings reflecting a weighted average cost of capital, and earnings growth assumptions. A discounted cash flow analysis requires management to make various assumptions about future sales, operating margins, capital expenditures, working capital, and growth rates. If the evaluation results in the fair value of the reporting unit being lower than the carrying value, an impairment charge is recorded. Indefinite-lived intangible assets are composed of certain tradenames and liquor licenses which are not amortized but are evaluated for impairment annually or more frequently if events or changes occur that suggest an impairment in carrying value, such as a significant adverse change in the business climate. Indefinite-lived intangible assets are evaluated for impairment by comparing each asset’s fair value to its book value. Management first determines qualitatively whether it is more likely than not that an indefinite‑lived asset is impaired. If management concludes that it is more likely than not that an indefinite-lived asset is impaired, then its fair value is determined by using the discounted cash flow model based on future revenues estimated to be derived in the use of the asset.
Other Intangible Assets	Other Intangible Assets Other finite-lived intangible assets consist of supply agreements, customer relations, non-competes, and loan origination costs. Separable intangible assets that are not determined to have an indefinite life are amortized over their useful lives and assessed for impairment only if and when circumstances warrant. Determination of an intangible asset’s fair value and estimated useful life are based on an analysis of pertinent factors including (1) the use of widely-accepted valuation approaches, such as the income approach or the cost approach, (2) the expected use of the asset by the Partnership, (3) the expected useful life of related assets, (4) any legal, regulatory or contractual provisions, including renewal or extension period that would cause substantial costs or modifications to existing agreements, and (5) the effects of obsolescence, demand, competition, and other economic factors. Should any of the underlying assumptions indicate that the value of the intangible assets might be impaired, we may be required to reduce the carrying value and remaining useful life of the asset. If the underlying assumptions governing the amortization of an intangible asset were later determined to have significantly changed, we may be required to adjust its amortization period to reflect a new estimate of its useful life. Any write‑down of the value or unfavorable change in the useful life of an intangible asset would increase expense at that time. Customer relations and supply agreements are amortized on a straight-line basis over the remaining terms of the agreements, which generally range from five to twenty years. Non-competition agreements are amortized over the terms of the respective agreements, and loan origination costs are amortized over the life of the underlying debt as an increase to interest expense.
Asset Retirement Obligations	Asset Retirement Obligations The estimated future cost to remove an underground storage tank is recognized over the estimated useful life of the storage tank. We record a discounted liability for the future fair value of an asset retirement obligation along with a corresponding increase to the carrying value of the related long-lived asset at the time an underground storage tank is installed. We then depreciate the amount added to property and equipment and recognize accretion expense in connection with the discounted liability over the remaining life of the tank. We base our estimates of the anticipated future costs for tank removal on our prior experience with removals. We review assumptions for computing the estimated liability for tank removal on an annual basis. Any change in estimated cash flows are reflected as an adjustment to both the liability and the associated asset. Long-lived assets related to asset retirement obligations aggregated $18 million and $20 million, and were reflected as property and equipment, net on our consolidated balance sheets as of December 31, 2020 and 2019, respectively.
Environmental Liabilities	Environmental Liabilities Environmental expenditures related to existing conditions, resulting from past or current operations, and from which no current or future benefit is discernible, are expensed. Expenditures that extend the life of the related property or prevent future environmental contamination are capitalized. We determine and establish a liability on a site-by-site basis when it is probable and can be reasonably estimated. A related receivable is recorded for estimable and probable reimbursements.
Revenue Recognition	Revenue Recognition Revenue from motor fuel is recognized either at the time fuel is delivered to the customer or at the time of sale. Shipment and delivery of motor fuel generally occurs on the same day. The Partnership charges wholesale customers for third-party transportation costs, which are recorded net in cost of sales. Through PropCo, our wholly-owned corporate subsidiary, we sell motor fuel to customers on a commission agent basis, in which we retain title to inventory, control access to and sale of fuel inventory, and recognize revenue at the time the fuel is sold to the end customer. In our Fuel Distribution and Marketing segment, we derive additional income from lease income, propane and lubricating oils, and other ancillary product and service offerings. In our All Other segment, we derive other income from merchandise, lottery ticket sales, money orders, prepaid phone cards and wireless services, ATM transactions, car washes, and other ancillary product and service offerings. We record revenue from other retail transactions on a net commission basis when a product is sold and/or services are rendered.
Lease Income	Lease Income Lease income from operating leases is recognized on a straight-line basis over the term of the lease.
Cost of Sales	Cost of Sales We include in cost of sales all costs incurred to acquire fuel and merchandise, including the costs of purchasing, storing, and transporting inventory prior to delivery to our customers. Items are removed from inventory and are included in cost of sales based on the retail inventory method for merchandise and the LIFO method for motor fuel. Cost of sales does not include depreciation of property and equipment as amounts attributed to cost of sales would not be significant. Depreciation is classified within operating expenses in the consolidated statements of operations and comprehensive income (loss).
Motor Fuel and Sales Taxes	Motor Fuel and Sales Taxes 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 wholesale direct sales to dealers, distributors and commercial customers is to exclude the collected motor fuel tax from sales and cost of sales. For retail locations where the Partnership holds inventory, including commission agent locations, motor fuel sales and motor fuel cost of sales include motor fuel taxes. Such amounts were $301 million, $386 million and $370 million, for the years ended December 31, 2020, 2019 and 2018, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in the consolidated statements of operations and comprehensive income (loss).
Deferred Branding Incentives	Deferred Branding Incentives We receive payments for branding incentives related to fuel supply contracts. Unearned branding incentives are deferred and amortized on a straight-line basis over the term of the agreement as a credit to cost of sales.
Lease Accounting	Lease Accounting At the inception of each lease arrangement, we determine if the arrangement is a lease or contains an embedded lease and review the facts and circumstances of the arrangement to classify lease assets as operating or finance leases under Topic 842. The Partnership has elected not to record any leases with terms of 12 months or less on the balance sheet. Balances related to operating leases are included in operating lease ROU assets, accrued expenses and other current liabilities, operating lease current liabilities and non-current operating lease liabilities in our consolidated balance sheets. Finance leases represent a small portion of the active lease agreements and are included in finance lease ROU assets, current maturities of long-term debt and long-term debt, less current maturities in our consolidated balance sheets. The ROU assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent the obligation of the Partnership to make minimum lease payments arising from the lease for the duration of the lease term. The Partnership leases a portion of its properties under non-cancelable operating leases, whose initial terms are typically five to fifteen years, with options permitting renewal for additional periods. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or greater. The exercise of lease renewal options is typically at the sole discretion of the Partnership and lease extensions are evaluated on a lease-by-lease basis. Leases containing early termination clauses typically require the agreement of both parties to the lease. At the inception of a lease, all renewal options reasonably certain to be exercised are considered when determining the lease term. The depreciable life of lease 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. Presently, because many of our leases do not provide an implicit rate, the Partnership applies its incremental borrowing rate based on the information available at the lease commencement date to determine the present value of minimum lease payments. The operating and finance lease ROU assets include any lease payments made and exclude lease incentives. Minimum rent is expensed on a straight-line basis over the term of the lease, including renewal periods that are reasonably assured at the inception of the lease. The Partnership is typically responsible for payment of real estate taxes, maintenance expenses, and insurance. The Partnership also leases certain vehicles, and such leases are typically less than five years. For short-term leases (leases that have term of twelve months or less upon commencement), lease payments are recognized on a straight-line basis and no ROU assets are recorded.
Earnings Per Unit	Earnings Per Unit In addition to limited partner units, we have identified incentive distribution rights (“IDRs”) as participating securities and compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the First Amended and Restated Agreement of Limited Partnership, as amended (the “Partnership Agreement”). Net income per unit applicable to limited partners is computed by dividing limited partners’ interest in net income, after deducting any incentive distributions, distributions on Series A Preferred Units and unvested phantom unit awards, by the weighted-average number of outstanding common units.
Stock and Unit-based Compensation	Unit-Based Compensation Under the Partnership's long-term incentive plans, various types of awards may be granted to employees, consultants, and directors of our General Partner who provide services for us. Compensation expense related to outstanding awards is recognized over the vesting period based on the grant-date fair value. The grant-date fair value is determined based on the market price of our common units on the grant date. We amortize the grant-date fair value of these awards over their vesting period using the straight-line method. Expenses related to unit-based compensation are included in general and administrative expenses.
Income Taxes	Income Taxes The Partnership is a publicly traded limited partnership and is not taxable for federal and most state income tax purposes. As a result, our earnings or losses, to the extent not included in a taxable subsidiary, for federal and most state purposes are included in the tax returns of the individual partners. Net earnings for financial statement purposes may differ significantly from taxable income reportable to Unitholders as a result of differences between the tax basis and financial basis of assets and liabilities, differences between the tax accounting and financial accounting treatment of certain items, and due to allocation requirements related to taxable income under our Partnership Agreement. As a publicly traded limited partnership, we are subject to a statutory requirement that our “qualifying income” (as defined by the Internal Revenue Code, related Treasury Regulations, and IRS pronouncements) exceed 90% of our total gross income, determined on a calendar year basis. If our qualifying income were not to meet this statutory requirement, the Partnership would be taxed as a corporation for federal and state income tax purposes. For the years ended December 31, 2020, 2019, and 2018, our qualifying income met the statutory requirement. The Partnership conducts certain activities through corporate subsidiaries which are subject to federal, state and local income taxes. These corporate subsidiaries include Sunoco Property Company LLC (“PropCo”) and Aloha. The Partnership and its corporate subsidiaries account for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized. The determination of the provision for income taxes requires significant judgment, use of estimates, and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in our financial statements only after determining a more-likely-than-not probability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. When facts and circumstances change, we reassess these probabilities and record any changes through the provision for income taxes.
