Basis of Presentation and Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of presentation	The accompanying unaudited condensed consolidated financial statements have been prepared by Valvoline Inc. (“Valvoline” or the “Company”) in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and Securities and Exchange Commission regulations for interim financial reporting, which do not include all information and footnote disclosures normally included in annual financial statements. Therefore, these condensed consolidated financial statements should be read in conjunction with Valvoline’s Annual Report on Form 10-K for the fiscal year ended September 30, 2025. Certain prior period amounts have been reclassified to conform to the current presentation. Sale of Global Products business On March 1, 2023, Valvoline completed the sale of its former Global Products reportable segment (“Global Products”) to Aramco Overseas Company B.V. The operating results and cash flows associated with and directly attributed to the Global Products disposal group are reflected as discontinued operations within these condensed consolidated financial statements. Unless otherwise noted, disclosures within these remaining Notes to Condensed Consolidated Financial Statements relate solely to the Company's continuing operations.
Use of estimates, risks and uncertainties	Use of estimates, risks and uncertainties The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent matters. Although management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ significantly from the estimates under different assumptions or conditions.
Recent accounting pronouncements	Recent accounting pronouncements The following accounting guidance relevant to Valvoline was either issued or adopted in the current fiscal year or is expected to have a meaningful impact on Valvoline in future periods upon adoption. Issued but not yet adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued guidance which enhances income tax disclosure requirements to include additional disaggregation within the effective tax rate reconciliation and income taxes paid. This guidance will be effective for Valvoline beginning with its fiscal 2026 annual financial statements, with early adoption permitted. The guidance must be applied prospectively, while retrospective application is permitted. The Company is continuing to assess the new guidance and is preparing for the related enhanced income tax disclosures in its fiscal 2026 annual financial statements. The Company does not expect this guidance will result in any changes to its results of operations, cash flows, or financial condition. In November 2024, the FASB issued guidance which requires enhanced disclosure of specified categories of expenses (purchases of inventory, employee compensation, depreciation and amortization) included in certain expense captions presented on the face of the income statement. This guidance will be effective for Valvoline beginning with its fiscal 2028 Form 10-K and interim periods beginning in fiscal 2029, with early adoption permitted, in addition to either prospective or retrospective application. The Company is currently evaluating this guidance to determine its adoption approach and the impact on the presentation and disclosure of its consolidated income statement and expenses. The Company anticipates its processes will be enhanced to address the disaggregation and disclosure requirements, though it does not expect adoption to impact its overall results from operations. In September 2025, the FASB issued new guidance related to accounting for internal-use software costs. The new standard removes references to software development project stages, making the guidance easier to apply and neutral across different software development methods. The update is effective for fiscal years beginning after December 15, 2027, including interim periods within those years. Early adoption is permitted and the guidance can be applied on a prospective transition approach, a retrospective transition approach, or a modified transition approach that is based on the status of the project and whether software costs were capitalized before the date of adoption. Valvoline does not expect the adoption of this guidance to have a material impact on its consolidated financial statements, based on its existing practices and policies.
