I have used 16 years. best oil out there

I love the my Harley Davidson motorcycle performs after serving with this product

First time oil change with Amsoil at 5,000 miles. Gained over tenths of a mile per gal.

This is the best oil you can put in your motorcycle by far.

Great oil for my 2011 Harley road king

best oil out there

I've used Amsoil in both my Harley's for the past combined 91,000 miles....great lubracant.. use 20/50, primary and tranny

Keeps internal wear to a minimum

Keeps my 2017 Harley Davidson Ultra running cool in this hot Florida weather. I have used it for many years and on many different motorcycles. Great product.

Started using Amsoil motorcycle oil about 8 years ago and just think it's the best oil made today, my Harley's love it. I used to use a different oil and think it still works, but i know this oil does the job better.
