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,” “Sunoco,” “we,” “us” or “our” should be understood to refer to Sunoco LP and its consolidated subsidiaries, unless the context clearly indicates otherwise. We are a Delaware master limited partnership. We are managed by our General Partner, which is owned by Energy Transfer. As of September 30, 2025, Energy Transfer owned 100% of the limited liability company interests in our General Partner, 28,463,967 of our common units and all of our IDRs. The consolidated financial statements include Sunoco LP, a publicly traded Delaware limited partnership, and its wholly owned subsidiaries. In the opinion of the Partnership’s management, such financial information reflects all adjustments necessary for a fair presentation of the financial position and the results of operations for such interim periods in accordance with GAAP. All significant intercompany accounts and transactions have been eliminated in consolidation. The operations of certain pipelines and terminals in which we own an undivided interest are proportionately consolidated in the accompanying consolidated financial statements.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Interim Financial Statements The accompanying interim consolidated financial statements have been prepared in accordance with GAAP. Pursuant to Regulation S-X, certain information and disclosures normally included in the annual consolidated financial statements have been condensed or omitted. The interim consolidated financial statements and notes included herein should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 14, 2025. Significant Accounting Policies As of September 30, 2025, there have been no changes in the Partnership's significant accounting policies from those described in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 14, 2025 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 $43 million and $33 million for the three months ended September 30, 2025 and 2024, respectively, and $107 million and $133 million for the nine months ended September 30, 2025 and 2024, respectively. Merchandise sales and cost of merchandise sales are reported net of sales tax in our consolidated statements of operations.

Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]
Mergers, Acquisitions and Dispositions Disclosures	Acquisitions Parkland Acquisition On October 31, 2025, we completed the previously announced acquisition of Parkland whereby the Partnership acquired all the outstanding shares of Parkland, in exchange for SunocoCorp units that were contributed by SunocoCorp to the Partnership at the close of the acquisition. Under the terms of the agreement, Parkland shareholders received 0.295 SunocoCorp units and C$19.80 for each Parkland share. Parkland shareholders could elect, in the alternative, to receive C$44.00 per Parkland share in cash or 0.536 SunocoCorp units for each Parkland share, subject to proration to ensure that the aggregate consideration payable in connection with the transaction would not exceed C$19.80 in cash per Parkland share outstanding as of immediately before close and 0.295 SunocoCorp units per Parkland share outstanding as of immediately before close. Parkland is a leading international fuel distributor, marketer and convenience retailer with operations in 26 countries across the Americas. Parkland’s functional currency is the Canadian dollar, and its consolidated structure includes subsidiaries with multiple other functional currencies. Subsequent to the Parkland Acquisition, the Partnership's consolidated financial statements will reflect Parkland as a subsidiary. The Partnership has engaged a third-party specialist to assist in the initial purchase price allocation in accordance with FASB ASC Topic 805; however, as of the date of this Form 10-Q filing, the initial accounting for this business combination is incomplete due to the timing of the close of the acquisition and the complexity of the acquired business. As part of the transaction, the Partnership repurposed and renamed an existing subsidiary as SunocoCorp. Prior to the Parkland Acquisition, SunocoCorp did not have any significant assets, liabilities or operations; in connection with the Parkland Acquisition, the Partnership deconsolidated SunocoCorp and SunocoCorp became a publicly traded entity classified as a corporation for U.S. federal income tax purposes. SunocoCorp's common units began trading on the New York Stock Exchange effective November 6, 2025. Subsequent to the Parkland Acquisition, SunocoCorp holds limited partnership units of Sunoco that are generally economically equivalent to Sunoco’s publicly traded common units on the basis of one Sunoco common unit for each outstanding SunocoCorp unit. For a period of two years following closing of the transaction, Sunoco will ensure that SunocoCorp unitholders receive distributions on a per unit basis that are equivalent to the per unit distributions to Sunoco unitholders. As a result of the Parkland Acquisition, we recognized $12 million of merger-related expenses during the nine months ended September 30, 2025, which are included in general and administrative expenses in our consolidated statement of operations. TanQuid Acquisition In March 2025, the Partnership entered into an agreement to acquire TanQuid for approximately €500 million (approximately $587 million as of September 30, 2025), including approximately €300 million of assumed debt. TanQuid owns and operates 15 fuel terminals in Germany and one fuel terminal in Poland. The transaction is expected to close in the fourth quarter of 2025, subject to customary closing conditions, and will be funded using cash on hand and amounts available under the Partnership's Credit Facility. Other Acquisitions In the first quarter of 2025, we acquired fuel equipment, motor fuel inventory and supply agreements in two separate transactions for total consideration of approximately $17 million. Aggregate consideration included $12 million in cash and 91,776 newly issued Sunoco common units, which had an aggregate acquisition-date fair value of approximately $5 million. In the second quarter of 2025, we acquired a total of 151 fuel distribution consignment sites in three separate transactions for total consideration of approximately $105 million, plus working capital. Aggregate consideration included $92 million in cash and 251,646 newly issued Sunoco common units which had an aggregate acquisition-date fair value of approximately $13 million. In the third quarter of 2025, we acquired approximately 70 fuel distribution consignment sites and 100 supply agreements in five separate transactions for total cash consideration of approximately $85 million, plus working capital. These transactions were accounted for as asset acquisitions, and the purchase price was primarily allocated to inventories, property, plant and equipment and other non-current assets.

Recent Transactions

March 2025 Senior Notes Offering and Redemption

In March 2025, the Partnership issued $1.00 billion aggregate principal amount of 6.250% senior notes due 2033 in a private offering. These notes will mature on July 1, 2033 and interest is payable semi-annually on January 1 and July 1 of each year. The Partnership used the net proceeds from the private offering to repay its $600 million aggregate principal amount of 5.750% senior notes due 2025 and to repay a portion of the outstanding borrowings under its Credit Facility.

September 2025 Senior Notes Offering

In September 2025, the Partnership issued $1.00 billion aggregate principal amount of 5.625% senior notes due 2031 and $900 million aggregate principal amount of 5.875% senior notes due 2034 in a private offering. These notes will mature on March 15, 2031 and March 15, 2034, respectively, and interest is payable semi-annually on March 15 and September 15 of each year, commencing on March 15, 2026. The Partnership used the net proceeds from this private offering (i) on the closing date of the Parkland Acquisition to fund a portion of the cash consideration for the Parkland Acquisition and related transaction costs, with the remaining proceeds used for general corporate purposes, and (ii) prior to the closing date of the Parkland Acquisition, to temporarily reduce the borrowings outstanding under the Partnership's Credit Facility and to pay interest and fees in connection therewith.

The 5.625% senior notes due 2031 and 5.875% senior notes due 2034 were originally subject to a special mandatory redemption requirement, which was eliminated upon closing of the Parkland Acquisition.

Parkland Senior Note Exchange

In October 2025, in connection with the Parkland Acquisition, the Partnership commenced a private offering to exchange C$1.60 billion Canadian dollar denominated notes (collectively, the “PKI CAD Notes”) and $2.60 billion U.S. dollar denominated notes (collectively, the “PKI USD Notes”). The exchange offer closed on November 4, 2025 with approximately C$1.47 billion of the PKI CAD Notes and approximately $2.58 billion of the PKI USD Notes being validly tendered and not validly withdrawn.

GoZone Bonds

NuStar Logistics' obligations include revenue bonds issued by the Parish of St. James, Louisiana pursuant to the Gulf Opportunity Zone Act of 2005 (the “GoZone Bonds”).

As reflected in the table below, the holders of the Series 2008 and Series 2010B GoZone Bonds are required to tender their bonds at the applicable mandatory purchase date in exchange for 100% of the principal plus accrued and unpaid interest, after which these bonds may be remarketed with a new interest rate established. Each of the Series 2010 and Series 2010A GoZone Bonds is subject to redemption on or after June 1, 2030 by the Parish of St. James, at our option, in whole or in part, at a redemption price of 100% of the principal amount to be redeemed plus accrued and unpaid interest. Interest on the GoZone Bonds is payable semi-annually on June 1 and December 1 of each year.

The Partnership recently completed the remarketing of $75 million principal amount of Series 2011 GoZone Bonds, which were previously repurchased on the mandatory purchase date of June 1, 2025 but were not remarketed at that time. The remarketed bonds were issued on October 1, 2025 and have a 3.70% interest rate, a mandatory purchase date of June 1, 2030, and a maturity of August 1, 2041.

NuStar Logistics’ agreements with the Parish of St. James related to the GoZone Bonds contain: (i) customary restrictive covenants that limit the ability of NuStar Logistics and its subsidiaries to, among other things, create liens, enter into certain sale leaseback transactions, and engage in certain consolidations, mergers or asset sales; and (ii) a repurchase provision which provides that if we undergo a change of control that is followed by a ratings decline that occurs within 60 days of the change of control, then each holder may require the trustee, with funds provided by NuStar Logistics, to repurchase all or a portion of that holder’s GoZone Bonds at a price equal to 101% of the aggregate principal amount repurchased, plus any accrued and unpaid interest. The Partnership and certain of its subsidiaries are guarantors to the agreements related to the GoZone Bonds.

Credit Facilities

The Partnership's Credit Facility, which previously was $1.50 billion and increased to approximately $2.46 billion upon closing of the Parkland Acquisition, matures on June 17, 2030, which date may be extended in accordance with the terms of the Credit Facility. The Credit Facility can be increased from time to time upon our written request, subject to certain conditions, up to an aggregate amount of $3.50 billion. As of September 30, 2025, we had no outstanding borrowings on the Credit Facility and $47 million in standby letters of credit were outstanding. The unused availability on the Credit Facility as of September 30, 2025 was $1.45 billion. The weighted average interest rate on the total amount outstanding as of September 30, 2025 was 6.42%. The Partnership was in compliance with all financial covenants as of September 30, 2025.

On May 16, 2025, the Credit Facility was amended, effective as of the Parkland Acquisition closing date, to, among other things, (i) increase the letter of credit sublimit from $100 million to $250 million, (ii) exclude Parkland and its subsidiaries from any requirement to provide a guarantee of the Obligations (as defined in the credit agreement) to the extent (x) such guarantee would not be permitted under any existing indebtedness of Parkland and its subsidiaries that remains outstanding after the Parkland Acquisition closing date or (y) such guarantee, if provided by a domestic subsidiary that is a direct or indirect subsidiary of a foreign subsidiary, could reasonably be expected to have material adverse tax consequences and (iii) permit the Partnership or any of its subsidiaries to incur (x) Parkland Acquisition bridge debt in an aggregate principal amount not to exceed $2.65 billion and (y) Parkland backstop bridge debt in an aggregate principal amount not to exceed $3.40 billion less reductions to such maximum amount as set forth in the credit agreement.

On June 17, 2025, the Credit Facility was amended to, among other things, (i) extend the maturity date of the revolving credit facility from May 3, 2029 to June 17, 2030, (ii) increase the aggregate principal amount of the revolving loan commitments from $1.50 billion to approximately $2.46 billion, upon closing of the Parkland Acquisition, (iii) increase the swingline sublimit on and

after the Parkland Acquisition closing from $100 million to $500 million, of which $250 million will be dedicated to swingline borrowings in Canadian Dollars and $250 million will be dedicated to swingline borrowings in U.S. Dollars, and (iv) add the ability to borrow revolving loans in Canadian Dollars.

On August 8, 2025, the Credit Facility was amended to, among other things, provide for up to $2.00 billion of cash that has been reserved by the Partnership to fund a portion of the cash consideration for the Parkland Acquisition to be netted in calculating the Net Leverage Ratio (as defined in the credit agreement) for purposes of the financial maintenance covenant.

On October 3, 2025, the Credit Facility was amended to, among other things, (i) amend the maturity limitations on the incurrence of additional unsecured indebtedness by the Partnership and its subsidiaries to permit both (a) the new notes to be issued by the Partnership in connection with the previously announced private exchange offers (the “Exchange Offers”) and (b) the guaranty by the Partnership of any senior notes of Parkland that remain outstanding after giving effect to the settlement of the Exchange Offers and (ii) exclude any domestic subsidiaries that are “foreign subsidiary holding companies” or subsidiaries of “controlled foreign corporations” from an obligation to provide a guaranty under the Credit Facility.

Upon the closing of the NuStar Acquisition, the commitments under NuStar’s receivables financing agreement were reduced to zero during a suspension period, for which the period end has not been determined. As of September 30, 2025, this facility had no outstanding borrowings.

Fair Value of Debt

The aggregate estimated fair value and carrying amount of our consolidated debt obligations as of September 30, 2025 were $9.60 billion and $9.48 billion, respectively. As of December 31, 2024, the aggregate fair value and carrying amount of our consolidated debt obligations were $7.45 billion and $7.49 billion, respectively. The fair value of our consolidated debt obligations is a Level 2 valuation based on the respective debt obligations' observable inputs for similar liabilities.

Revenue (Notes)

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

Revenue

Disaggregation of Revenue

Revenues from our Fuel Distribution segment are derived from the sale of fuel, non-fuel and lease income. Fuel sales consist 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 price based on a formula which includes 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 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. To determine when control transfers to the customer, the shipping terms of the contract are assessed as a primary indicator of the transfer of control. For free on board 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. Non-fuel revenue includes merchandise revenue that comprises the in-store merchandise and food service sales at company-operated retail stores and other revenue such as credit card processing, car washes, lottery and other services. Lease revenue is derived from the leasing or subleasing of real estate used in the retail distribution of motor fuels.

Revenues from our Pipeline Systems segment are derived from interstate and intrastate pipeline transportation of refined products, crude oil and anhydrous ammonia and the applicable pipeline tariff on a per barrel basis for crude oil or refined products and on a per ton basis for ammonia.

Revenues from our Terminals segment include fees for tank storage agreements, under which a customer agrees to pay for a certain amount of storage in a tank over a period of time (storage terminal revenues) and throughput agreements, under which a customer pays a fee per barrel for volumes moving through our terminals (throughput terminal revenues). Our terminals also provide blending, additive injections, handling and filtering services for which we charge additional fees. Additionally, we lease certain of our storage tanks in exchange for a fixed fee, subject to an annual consumer price index adjustment. We recognized lease revenues from these leases of $11 million and $35 million for the three and nine months ended September 30, 2025, respectively, which are included in “Service revenue” in our consolidated statement of operations.

The following table depicts the disaggregation of revenue:

Commitments And Contingencies	9 Months Ended
Commitments And Contingencies	Sep. 30, 2025
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation From time to time, the Partnership is involved in various legal proceedings and claims arising out of our operations in the normal course of business. Such proceedings are subject to the uncertainties inherent in any litigation, and we regularly assess the need for accounting recognition or disclosure of any related contingencies. We maintain liability insurance with insurers with coverage and deductibles management believes are reasonable and prudent. 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 be adequate to protect us from material expenses related to product liability, personal injury or property damage in the future. Based on currently available information, we believe it is unlikely that the outcome of known matters would have a material adverse impact on our financial condition, results of operations or cash flows. New York Motor Fuel Excise Tax Audit New York State issued a motor fuel excise tax assessment to Sunoco LLC, a wholly owned subsidiary of the Partnership, in the amount of approximately $20 million, exclusive of penalties and interest, for the periods of March 2017 through May 2020. Sunoco LLC intends to pursue all available avenues of appeal and contest the full amount of the assessment. Sunoco LLC cannot predict the outcome of this matter at this time

Preferred Units	9 Months Ended
Preferred Units	Sep. 30, 2025
Equity [Abstract]
Preferred Stock	Preferred Units September 2025 Series A Preferred Units Offering In September 2025, the Partnership closed a private offering of 1.5 million of its 7.875% Series A Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Units (the “Series A Preferred Units”) at an offering price of $1,000 per unit. The Partnership received net proceeds of approximately $1.47 billion from the sale of the Series A Preferred Units after deducting the initial purchasers' discount and other estimated offering expenses. The Partnership used the net proceeds from this private offering (i) on the closing date of the Parkland Acquisition to fund a portion of the cash consideration for the Parkland Acquisition, and (ii) prior to the closing date of the Parkland Acquisition, to temporarily reduce the borrowings outstanding under the Partnership's Credit Facility and to pay interest and fees in connection therewith. Distributions on the Series A Preferred Units will be cumulative from the date of original issuance and will be payable semi-annually in arrears commencing on March 18, 2026, when, as, and if declared by our general partner out of legally available funds for such purpose. An initial distribution on the Series A Preferred Units will be paid on March 18, 2026 in an amount equal to approximately $39.38 per Series A Preferred Unit. The Series A Preferred Units were originally subject to a special mandatory redemption, which was eliminated upon closing of the Parkland Acquisition. Prior to the closing, the special mandatory redemption was contingent on conditions that were not entirely within the control of the Partnership; therefore, the Series A Preferred Units were reflected as temporary equity on the Partnership’s consolidated balance sheet as of September 30, 2025. Subsequent to the closing of the Parkland Acquisition, the Series A Preferred Units will be reflected as equity on the Partnership's consolidated balance sheet.

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

Segment Reporting

Description of Segments

Our consolidated financial statements reflect three reportable segments: Fuel Distribution, Pipeline Systems and Terminals.

Fuel Distribution. Our Fuel Distribution segment supplies motor fuel to independently-operated dealer stations, distributors, commission agents and other consumers. Also included in our Fuel Distribution segment is lease income from properties that we lease or sublease, as well as the Partnership’s credit card services, franchise royalties and retail operations in Hawaii and New Jersey.

Pipeline Systems. As of September 30, 2025, our Pipeline Systems segment included an integrated pipeline and terminal network comprised of approximately 6,000 miles of refined product pipeline (including the pipeline of J.C. Nolan), approximately 6,000 miles of crude oil pipeline (including the pipeline of ET-S Permian), approximately 2,000 miles of ammonia pipeline and 67 terminals.

Terminals. As of September 30, 2025, our Terminals segment was composed of four transmix processing facilities and 56 refined product terminals (two in Europe, six in Hawaii and 48 in the continental United States).

Segment Operating Results

We report Adjusted EBITDA by segment as a measure of segment performance. We define Adjusted EBITDA as earnings before net interest expense, income taxes, depreciation, amortization and accretion expense, non-cash unit-based compensation expense, gains and losses on disposal of assets, non-cash impairment charges, losses on extinguishment of debt, unrealized gains and losses on commodity derivatives, inventory valuation adjustments, and certain other operating expenses reflected in net income that we do not believe are indicative of ongoing core operations. Inventory valuation adjustments that are excluded from the calculation of Adjusted EBITDA represent changes in lower of cost or market reserves on the Partnership's inventory. These amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period.

The following tables present financial information by segment for the three and nine months ended September 30, 2025 and 2024:

(1)Dilutive effects are excluded from the calculation of diluted net income (loss) per common unit for periods where the impacts would have been antidilutive.

For certain periods reflected above, distributions paid for the period exceeded net income attributable to partners. Accordingly, the distributions paid to our General Partner, including incentive distributions, further exceeded net income, and as a result, a net loss was allocated to the common unitholders for the period.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Interim Financial Statements The accompanying interim consolidated financial statements have been prepared in accordance with GAAP. Pursuant to Regulation S-X, certain information and disclosures normally included in the annual consolidated financial statements have been condensed or omitted. The interim consolidated financial statements and notes included herein should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 14, 2025.
Recently Issued Accounting Pronouncements	Significant Accounting Policies As of September 30, 2025, there have been no changes in the Partnership's significant accounting policies from those described in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 14, 2025
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 $43 million and $33 million for the three months ended September 30, 2025 and 2024, respectively, and $107 million and $133 million for the nine months ended September 30, 2025 and 2024, respectively.

Revenue from Contract with Customer (Policies)	9 Months Ended
Revenue from Contract with Customer (Policies)	Sep. 30, 2025
Revenue from Contract with Customer [Abstract]
Revenue	Disaggregation of Revenue Revenues from our Fuel Distribution segment are derived from the sale of fuel, non-fuel and lease income. Fuel sales consist 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 price based on a formula which includes 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 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. To determine when control transfers to the customer, the shipping terms of the contract are assessed as a primary indicator of the transfer of control. For free on board 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. Non-fuel revenue includes merchandise revenue that comprises the in-store merchandise and food service sales at company-operated retail stores and other revenue such as credit card processing, car washes, lottery and other services. Lease revenue is derived from the leasing or subleasing of real estate used in the retail distribution of motor fuels. Revenues from our Pipeline Systems segment are derived from interstate and intrastate pipeline transportation of refined products, crude oil and anhydrous ammonia and the applicable pipeline tariff on a per barrel basis for crude oil or refined products and on a per ton basis for ammonia. Revenues from our Terminals segment include fees for tank storage agreements, under which a customer agrees to pay for a certain amount of storage in a tank over a period of time (storage terminal revenues) and throughput agreements, under which a customer pays a fee per barrel for volumes moving through our terminals (throughput terminal revenues). Our terminals also provide blending, additive injections, handling and filtering services for which we charge additional fees. Additionally, we lease certain of our storage tanks in exchange for a fixed fee, subject to an annual consumer price index adjustment. We recognized lease revenues from these leases of $11 million and $35 million for the three and nine months ended September 30, 2025, respectively, which are included in “Service revenue” in our consolidated statement of operations. Costs to Obtain or Fulfill a Contract The Partnership recognized amortization on capitalized costs incurred to obtain contracts of $9 million for the three months ended September 30, 2025 and 2024, and $28 million and $26 million for the nine months ended September 30, 2025 and 2024, respectively.
