VTwin Oil Finder Maps Harley-Davidson Oil by Year and Model
A model-year lookup tool for Harley-Davidson engine, primary, and transmission oil capacities and grades.
Field notes
The lookup separates engine, primary, and transmission requirements, including older Harley-Davidson models that share oil between compartments. Its coverage runs from 1949 through 2026 and is organized around 2,654 year-and-model combinations. Each result has a stable path such as /oil/2025/flhx/, making a specific service reference easier to bookmark or pass to someone else. The homepage says the figures represent a full service including filter and cautions users to confirm them against a workshop manual.
