| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Basis of Presentation | Basis of Presentation — Murphy USA was incorporated in March 2013 and, in connection with its incorporation, Murphy USA issued 100 shares of common stock, par value $0.01 per share, to Murphy Oil Corporation (“Murphy Oil”) for $1.00. On August 30, 2013, Murphy USA was separated from Murphy Oil through the distribution of 100% of the common stock of Murphy USA to holders of Murphy Oil stock. Murphy USA Inc., Murphy Oil USA, Inc. and its subsidiaries operate on a calendar year basis. In preparing the financial statements of Murphy USA in conformity with accounting principles generally accepted in the United States, management has made a number of estimates and assumptions related to the reporting of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities. Actual results may differ from these estimates. The Company does not have any components of comprehensive income; therefore, comprehensive income is equal to net income (loss) reported in the Consolidated Statements of Income for all periods presented. Interim Financial Information — The interim period financial information presented in these consolidated financial statements is unaudited and includes all known accruals and adjustments, in the opinion of management, necessary for a fair presentation of the consolidated financial position of Murphy USA and its results of operations and cash flows for the periods presented. All such adjustments are of a normal and recurring nature.

| Recently Issued Accounting Standards | Recently Issued Accounting Standards— In November 2024, the FASB issued ASU 2024-03, "Disaggregation of Income Statement Expenses." This ASU addresses investor requests for more granular information about an entity’s expenses, allowing investors to better understand performance, prospects for future cash flows, and comparability over time and with other entities. The primary goal is to improve the decision-usefulness of expense information on public companies’ income statements through disaggregation of relevant expense captions in the notes to the financial statements. The amendments in this update are effective for the Company for annual periods beginning after December 15, 2026, and interim periods in the year beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied either prospectively or retrospectively. The Company is assessing the impact of the standard on the Company's consolidated financial statements. In November 2025, the FASB issued ASU 2025-09, “Derivatives and Hedging (Topic 815)—Hedge Accounting Improvements.” This ASU is intended to more closely align financial reporting with the economics of some of an entity’s risk management activities. The changes are in response to stakeholder feedback from implementing ASU 2017-12 and the effects of LIBOR cessation. The main amendments relate to cash flow hedging, but some of the amendments affect certain fair value and net investment hedges. The amendments will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted, and the amendments are to be applied prospectively. The Company is currently assessing the impact of the standard on the consolidated financial statements. In December 2025, the FASB issued ASU 2025-11, "Interim Reporting (Topic 270)—Narrow-Scope Improvements". This ASU clarifies the interim reporting requirements by improving navigability of Topic 270 and more clearly specifying what disclosures are required in an interim reporting period. It is not intended to significantly change interim reporting or expand or reduce interim disclosure requirements. The amendments will be effective for interim reporting periods beginning after December 15, 2027. Early adoption is permitted, and the amendments may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the standard on the consolidated financial statements and does not expect the adoption to have a material impact. In December 2025, the FASB issued ASU 2025-12, "Codification Improvements". This ASU focuses on clarifying guidance, correcting unintended errors and making minor editorial refinements across the Codification and is not expected to have a significant effect on accounting practices. The amendments are effective for annual and interim periods in fiscal years beginning after December 15, 2026. Early adoption is permitted. Most amendments may be applied prospectively or retrospectively, except for the Topic 260 (earnings per share) amendments, which require retrospective application. The Company is currently evaluating the impact of the standard on the consolidated financial statements and does not expect the adoption to have a material impact. In May 2026, the FASB issued ASU 2026-02, "Environmental Credits and Environmental Credit Obligations (Topic 818)." This ASU is intended to improve the financial accounting for environmental credits and environmental credit obligations and establishes recognition, measurement, presentation, and disclosure requirements for all entities that generate, purchase, or receive environmental credits or have regulatory compliance obligations that may be settled with environmental credits. The amendments are effective for annual and interim periods in fiscal years beginning after December 15, 2027. Early adoption is permitted, and the amendments may be applied through a cumulative-effect adjustment to opening retained earnings at the beginning of the annual period of adoption. Upon adoption, any prior periods presented are not required to be recast. The Company is currently evaluating the impact of the standard on the consolidated financial statements.

| Revenue Recognition | Revenue Recognition Revenue is recognized when obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our petroleum products, convenience merchandise, Renewable Identification Numbers ("RINs") and other assets to our third-party customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Excise and sales tax that we collect where we have determined we are the principal in the transaction have been recorded as revenue on a jurisdiction-by-jurisdiction basis. The Company enters into buy/sell and similar arrangements when petroleum products are held at one location but are needed at a different location. The Company often pays or receives funds related to the buy/sell arrangements based on location or quality differences. The Company accounts for such transactions as non-monetary exchanges under existing accounting guidance and typically reports these on a net basis in the Consolidated Statements of Income. Marketing segment Petroleum product sales (at retail). For our retail store locations, the revenue related to petroleum product sales is recognized as the fuel is pumped to our customers. The transaction price at the pump typically includes some portion of sales or excise taxes as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass-through basis are not recognized as revenue and they are recorded to a liability account until they are paid. Our customers typically use a mixture of cash, checks, credit cards and debit cards to pay for our products as they are received. We have accounts receivable from the various credit/debit card providers at any point in time related to product sales made on credit cards and debit cards. These receivables are typically collected in to seven days, depending on the terms with the particular credit/debit card providers. Payment fees retained by the credit/debit card providers are recorded as Store and other operating expenses in the Consolidated Statements of Income. Petroleum product sales (at wholesale). Our sales of petroleum products at wholesale are generally recorded as revenue when the deliveries have occurred and legal ownership of the product has transferred to the customer. Title transfer for bulk refined product sales typically occurs at pipeline custody points and upon trucks loading at product terminals. For bulk pipeline sales, we record receivables from customers that are generally collected within a week from custody transfer date. For our rack product sales, the majority of our customers' accounts are drafted by us within 10 days from product transfer. Merchandise sales. For our retail store locations, the revenue related to merchandise sales is recognized as the customer completes their purchase at our locations. The transaction price typically includes some portion of sales tax as levied in the respective jurisdictions. Those taxes that are collected for remittance to governmental entities on a pass-through basis are not recognized as revenue and they are recorded to a liability account until they are paid. As noted previously, a mixture of payment types are used for these revenues and the same terms for credit/debit card receivables are realized. With respect to merchandise sales revenue we must determine whether we are the principal or agent for some categories of merchandise such as scratch-off lottery tickets, lotto tickets, newspapers and other small categories of merchandise. For scratch-off lottery tickets, we have determined we are the principal in the majority of the jurisdictions and therefore we record those sales on a gross basis. We have some categories of merchandise (such as lotto tickets) where we are the agent and the revenues recorded for those transactions are our net commission only. The Company offers loyalty programs through each of its branded retail locations. The customers earn rewards based on their spending or other promotional activities. These programs create a performance obligation which requires us to defer a portion of sales revenue to the loyalty program participants until they redeem their rewards. The rewards may be redeemed for free or discounted merchandise or cash discounts at all stores and on fuel purchases at Murphy branded stores. Earned rewards expire after an account is inactive for a period of 90 days at Murphy branded stores, while certain QuickChek rewards require use within the month. We recognize loyalty revenue when a customer redeems an earned reward. Deferred revenue associated with both rewards programs are included in Trade accounts payable and accrued liabilities in our Consolidated Balance Sheets. The deferred revenue balances at June 30, 2026 and December 31, 2025 were immaterial. RINs sales. For the sale of RINs, we recognize revenue when the RIN is transferred to the counter-party and the sale is completed. Receivables from our counter-parties related to the RIN sales are typically collected within five days of the sale. Other revenues. Items reported as other operating revenues include collection allowances for excise and sales tax and other miscellaneous items and are recognized as revenue when the transaction is completed.

| Derivative Instruments | DERIVATIVE INSTRUMENTS — The Company makes limited use of derivative instruments to manage certain risks related to commodity prices and interest rates. The use of derivative instruments for risk management is covered by operating policies and is closely monitored by the Company’s senior management. The Company does not hold any derivatives for speculative purposes, and it does not use derivatives with leveraged or complex features. Derivative instruments are traded primarily with creditworthy major financial institutions or over national exchanges such as the New York Mercantile Exchange (“NYMEX”). For accounting purposes, the Company has not designated commodity derivative contracts as hedges, and therefore, it recognizes all gains and losses on these derivative contracts in its Consolidated Statements of Income.

| Lease Accounting | The Company determines if an arrangement is a lease or contains a lease at inception. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. The Company's leases have remaining lease terms of approximately 1 year or less to 33 years, which may include the option to extend the lease when it is reasonably certain the Company will exercise the option. Most leases include one or more options to renew, with renewal terms that can extend the lease term from 5 to 20 years or more. The exercise of lease renewal options is at the Company's sole discretion. Due to the uncertainties of future markets, economic factors, technology changes, demographic shifts and behavior, environmental regulatory requirements and other information that impacts decisions as to store location, management has determined that it was not reasonably certain to exercise contract options and they are not included in the lease term. Additionally, short-term leases and leases with variable lease costs are immaterial. The Company reviews all options to extend, terminate, or otherwise modify its lease agreements to determine if changes are required to the right-of-use assets and liabilities. As the implicit interest rate is not readily determinable in most of the Company's lease agreements, the Company uses its estimated secured incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.
