Motorcycle Oil, Primary Fluid & Transmission Fluid: What’s the Difference?


Some V-twin motorcycles, like modern Indian* and Victory* bikes, use a shared sump, meaning they use the same lubricant in the engine, transmission and primary chaincase. Most Harley-Davidson* motorcycles, however, use a separate sump for each lubricant. This presents Harley owners with a choice: Use the same lubricant in all three areas of the bike, or use a separate lubricant formulated and labeled for each area.

For riders who desire the simplicity and convenience of using one lubricant for all three areas, following our primary recommendation of 20W-50 Synthetic V-Twin Motorcycle Oil in all three areas is the best choice.

For riders who prefer dedicated lubricants for each area of their bikes and don’t mind a few extra bottles of oil lying around the garage, steer them toward our full line of V-twin lubricants.

Either way, they can’t go wrong.
