Customer Ratings & Reviews

I've been using this oil for about 20 years. I've had multiple experiences with the motorcycle and in my vehicles with heat issues. I have been at bike week numerous times when other v-twins were pulled off the side of the road overheating and I kept on rolling! I also had to drive a car home with no coolant in it with Amsoil and never even went above a quarter of the way on the temperature gauge. I'm telling everybody Amsoil is the way to go and I will never use any other oil in my bike or truck ever again!! It is the best!

Fast shipping and good oil

First change since getting bike, won't use anything but... The shipping was unbelievably fast, all I can say is thanks much.

Works good

Keeps engine running like new. I ride pretty hard on the upper RPM range. Engine shows little signs of wear. I attribute this to frequent oil changes with amsoil

Good product quick delivery

I have used Amsoil for years in many different types of vehicles. I haven't found another oil that will out perform Amsoil. I have ran it in all my motorcycles and have gotten more mileage out of the engines than other riders with the same bikes.

Love the product! Keeps the bike cooler.

There is no comparison between this and other oils. It outlasts ant performs any other oil I have ever used!

Why would anyone pay for over priced oil so called top rated best, at the membership price you can’t beat it anywhere. Amsoil has been proven to be the best by pro racers.

Outstanding oil, makes my shifts much smoother.

My big cc air/oil cooled Ducatis get well used and ridden hard. Amsoil helps keep them in tip top shape

I just put this oil in my bike yesterday. I took a ride after, and the bottom end sounded more quiet than before.

My twin cam Harley Super Glide is air cooled. This oil protects the engine even on 95 degree days. You need this oil in your air cooled engine!

Use it my 14FatLo. Will not use any other oil. I’m my opinion at this moment in times it’s the best.

The Best Oil I have ever used, makes my Harley-Davidson run better, cooler, and quieter,and the engine, Transmission & primary should last a long time using Amsoil 20W-50

My first time using amsoil on my 2001 Harley-Davidson Wide-Glide was easy and is a good product i would use again bottle was good shape fit in to the space i need to put oil in the bike without making a mess

In my opinion this is the best engine oil for my Harley Davidson Fatboy motorcycle. I have inspected some of the internals on my engine, and at 46K miles, there is very little wear indicated. I also use AMSOIL in my trucks engine. I highly recommend this synthetic engine oil to anyone who owns a motorcycle, especially an air cooled engine.

Great product. Use in all 3 holes in my Ultra classic.

This oil can go the distance without breaking down.
