Customer Ratings & Reviews

Ever since I've started to use Amsoil products, my vehicles have been running more efficiently. I would highly recommend Amsoil products to anyone wishing to reduce the wear and tear on their vehicles.

To keep all mine and my family cars and truck and motorcycles running at there best

Number one in protection and performance.

Since back in 80s amsoil rep sold me on this oil. This is the best motor oil .

I use signature series 5W-30 to change my truck's oil

It is a great product, can do 15,000 oil changes (turbo) with 15,000 filter with superior protection at a cost less than a regular oil change. Can't beat that!!

I will be using this in my 2017 Chevy Silverado 4x4 for as long as I own it! Great product!

Great pill always looks good after extended drain intervals!!

I have used Amsoil previously on other vehicles and I currently use this oil on two different Jeeps I own.

This is used in a 2012 STi. Engine seems to like it.

Only oil I use for any engine I own. An investment worth the payout.

I've used Amsoil for over 20 years! This is by far the best oil you can buy! The warranty speaks for itself!!!!

I use this oil in my pickup

I simply use AMS OIL in all my cars and don't look elsewhere. Never had a problem, all engines work like new, no worries. You want the best, look no further.

This my first time using the oils, and I like it...I would go back to conventional oil.. Thanks AMSOL...

I use ss 5w-20 in my pickup, good startup when cold.

I run Amsoil in all our company fleet vehicles, my personal vehicles and all my race bikes. Our one panel van hit 600,000 km and still runs awesome doesn't burn oil and still shifts perfectly, I trust Amsoil for everything.

I've used AMSOIL for decades. It has saved me lots of $$$ in repairs.

I run a lot of highway miles. The truck has run smoother and is very quiet. I also notice that dry startup is much quieter. My mileage has stayed nearly the same.

Have been using Amsoil in our cars and motorcycles now for over 20 years. Top notch product at a reasonable price.
