Customer Ratings & Reviews

Great product fast shipping good price

Was in my kit, fantastic oil.

In my Harleys, I’ve mostly run motor oil and all three holes oil transmission and primary. I gave this oil try on my 2001 Harley Davidson softail what’s the transmission seem to be a little clunky it quieted it down and made it smoother. I will use this in my transmissions from now on. I believe the difference is it’s a straight 50 weight instead of a 2050 or 1550

Always have used Amsoil in my Harley form the first oil change when new. Been using Amsoil in my dirt bikes and my utv and my Cadillac.

I would use anything else in my Harley's. Be using Amsoil for over 10 years.

Amsoil is the best on the market, true synthetic, the viscosity lasts, and my transmission shifts smoother.

I've used nothing but Amsoil since I purchased the bike. To me it's the best. Especially the transmission oil. The bike shifts like butter.

Been running this from the beginning on my 2021 Harley 30,000 miles. Will continue to use.

Happy to have a variety of Amsoil products shipped right to door. It’s impossible to find them on store shelves.
