Customer Ratings & Reviews

The best oil you can buy. Been using Amsoil engine oil for many years without any issues. Dealers that it ships from are always awesome and quick to ship. I love Amsoil.

I was skeptical that the oil would last a full year but it in fact did and was the one oil change annually I had to do.

Amsoil is a superior oil and I will continue to use it as I have for many years!

This oil have just what it take for those noisy Coyote engine. That typewriter tick that drive you up the wall and so I don’t have problem. Thank to Amsoil it been worry free for me and I love your products.

Love this oil . 6000 miles between oil changes , and great protection for my daily drivers

Would recommend,,, you want the best this is it... 👍

This oil is amazing it keeps the motor clean and cuts down on wear

This is the best oil on the market. I have changed my explorer and my eco boost truck. Completely different vehicles. Trust me the eco boosts go bad with bad oil and no problems with them.

I use Amsoil in all of my vehicles

As usual good service and delivery for a superior product.

This oil is second to none. Great protection and great performance.

First time changing oil and wanted to use the best of the best. Great quality oil, car seems quieter but the power is still there when needed. Excellent choice, thanks Amsoil!

I have been a user of this produce for as long as I can remember. My Father was a user in his vehicles cals and I guess I didn’t fall far from the tree. I have used this oil in my car since the first oil change and I has not had any issues with my vehicle. I would highly recommend this and all of their products

I'm glad there is a brand I can trust for all my engine needs. Since I'm retired, I don't put much miles on so it's good to know I can go all year on one oil change. Also the OEM filters are trash. 50% or less effiiciency.

I started using synthetic oil when I bought my 2011 Sierra 5.3L and I started with Mobile1 then after awhile switched to RoyalPurple then went all out and bought Amsoil! Jesus this stuff is crazy expensive but you get what you pay for! Ever since I started using Amsoil I don't have to worry about engine failure due to lubrication. My truck has been tuned to 390hp from the factory 325hp. She will turn 6-grand going thru the gears and im confident i have the best of the best lubrication available! Like I said it did hurt paying that much for oil but it's much cheaper than an engine replacement! My oil pressure is higher than it was using other oils. All the reviews I've read about oils and Amsoil came out on top every time! Especially in the heat & viscosity test! Heat had no effect on Amsoil and that right there sold me!
