V-twin kitBy WILLIAM, a Verified Buyer from Alabama on May 08, 2025This is a great kit for the fluid change on motorcycles. I just wish the kit included ( as is the case for some kits) the transmission and primary oils. This is the only fluids that I have used on my motorcycles, ever. Prices are good, especially if you become a “preferred” customer.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Harley FLHTCUIBy MICHAEL A., a Verified Buyer on May 06, 2025Engine runs cooler and quieter than the screaming eagle oil that the dealership used during warranty period. The dealership used their screaming eagle oil in the primary, transmission and engine. I had loud transmission noise wen shifting gears, clutch would start to chatter after about 2500 miles and the lifters in the engine would become noisy. After replacing with all Amsoil products these problems went away.Bottom LineYes, I would recommend this to a friend.Was this review helpful?
