Customer Ratings & Reviews

Only oil I trust period!!!

It keeps engine running much cooler and almost totally stops engine wear. I have toren down air cooled motorcycle engines run on Amsoil for over 100k miles and all major parts were still within factory specs.

Great oil and good service from order to delivery

Although it says V-Twin on the bottle, I have been using Amsoil 20w50 motorcycle oil for my 1976 CB750 for years. Since I ride hard all the time, I choose to protect my bike with a 20w50.

Love the oil and the time it took to get. Wish it came with a amsoil sticker so I could help advertise for you all

Works great in my harley ,runs cooler.

I am on my second oil change and no problem. I do enjoy just changing oil twice a year [ 20000 miles a year] .

I have used this product for years, it’s the only oil I have used in the last 4 bikes I’ve owned, and the only oil I’ll ever use.

great product, fast delivery

I have used this in my Harleys and have put hundreds of thousands of miles on them.

This the only oil I will use in my bike

I've been using Amsoil V-Twin motorcycle oil in my Harley for years now. It has over 100,000 miles on it and still going strong.

Great product would recommend to anyone.

Like i said there is no way im using any other oil in my Harley! Amsoil gives you the protection you need with a big heavy touring bike, especially in the high heat that i ride!! Its the best!!

Upgraded my oil pan on my motorcycle after 66,000 miles and there is no signs of sludge. Been running Amsoil in all my vehicles since 2005. Don’t want to run anything other than Ams

My Harley oil runs way cooler (around 230 degrees) compared to 300 + degrees when I was using Harley’s Syn3 oil. What a difference in performance, reliability, personal comfort and peace of mind when I switched over to Amsoil.

I live in a very hot environment and Amsoil is the only oil I use. I have never had an oil related issue in over 20 years. They also have the fastest shipping around, great job Amsoil.

I just recently bought a 2018 HD TriGlide. it had 5100 miles on it. All three systems needed (probably the first) oil changes. My Best friend has been using Amsoil for over 20 years, his bike runs great! First ride was to Coco Beach, FL and back 460 miles. Also, my shifter seemed quieter, after the oil change. Plus I actually researched and read many reviews. I'll be keeping an eye on everything for the next 5000 miles.

Awesome product Great price
