Customer Ratings & Reviews

Amsoil Synthetic and filter combo is the best. I change fluids religiously, every 5k miles, and I ride hard, in all weather conditions. The viscosity is still good at 5k. Switching from the OEM to Amsoil, the engine immediately ran cooler, smoother and with less rocker noise (which is inherent to V-twins). Amsoil synthetic is truly worth the purchase and use.

I've used nothing but Amsoil since I purchased the bike. To me it's the best

This is the best oil ever the only oil I use on my Harley and my 2018 F150 highly recommend it

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

Very satisfied with the price and service , fast delevery

Have used this oil for over 30,000 miles in my present bike an 02' Police Electraglide and over 40,000 miles in my 05' Electraglide with very good results. I would recommend this to anyone who would like long engine life.
