Every model code from Panhead to Milwaukee-Eight.
Engine, primary and transmission in litres, with the oil grade Harley specifies for each.
Matching oils from retailers in the UK, USA, Canada, Australia, New Zealand and Europe.
Capacities are the factory figures for a full service including filter, in litres. Where Harley-Davidson lists 20W50 full synthetic as acceptable in the primary and transmission as well as the engine, the model page says so. Older models that share oil between compartments are shown with the compartments they actually have.
Every year and model has its own address in the form /oil/year/model-code/, for example /oil/2025/flhx/, so results can be linked, bookmarked and quoted directly.
