Eurol Parts & Accessories

Eurol are a Dutch lubricant specialist formulating engine oils, primary chaincase lubricants, and transmission fluids specifically for Harley-Davidson air-cooled V-twins — not adapted automotive lubricants, but products developed for the thermal loads and operating characteristics of H-D powerplants. The range extends to cleaning and workshop chemicals covering the full maintenance routine.

If you're particular about what goes into your engine and want lubricants built for the application rather than repurposed from something else, Eurol is worth knowing about.
