Customer Ratings & Reviews

Since Amsoil came on line I have used it in my HD motorcycle. The 20w-50 oil long life and quality makes me confident that my HD engine is protected. We ride a lot in the mountains which produces a lot of heat - Amsoil keeps the temperatures within the standards and keeping me happy. I've been a preferred customer for many years and the service when I order is easy and delivery is quick. Never fail oil or customer support.

Used it once and will not go back to Harley oil.

I now the Amsoil product : PERFECT

Bike run so good

Best protection and piece of mind money can buy for your vehicles or toys! Extra fast shipping and top prices.

Best oil I ever used, hands down and I have tried them all !

Everything u need

Keeps my 2003 v rod running great, and shifting is much better when finding neutral. Great product!!

I was pleasantly surprised that I could see a difference while running this in my Indian. I highly recommend this stuff to anyone with a V-Twin.

👍🏻

I just started running AMS oil in my harley this year and it's much better and less expensive than the crap HD dealers sell.

J’utilise cette huile dans mon Indian Roadmaster

Bike runs 10 degrees cooler using this oil

If you ride a H/D, please do yourself a favor and use ALL the products. Pay a smidge more for the best quality, your bike will reward you for it now and in the future.

AMS Oil is the only supplier for this grade of synthetic oil. I use it in my 1977 Yamaha XS750D. The oil works very well, with reduced engine temperature critical on an air-cooled engine. I also expect less wear on internal components.

Running quite , and cooler

Got the oil quickly. Well satisfied. Thank you

I started to use amsoil in 2010 and would not use anything else , I be taking motors apart that use dinosaur stuff and there would be sludge in the bottom but not amsoil
