Customer Ratings & Reviews

My oil of choice. I trust in my 5 vehicles. Definitely would recommend to all do it yourselfers.

Well I wont know if there is a difference in using this oil until I do my BLACKSTONE LABS check at 5000 miles. So far I only use good synthetic oils from known brand names. My car has 180500 miles. Once I do the lab check, if I can do a update I will.

For year I had used all types of so called advanced or full synthetic oils on the market. Until I try Amsoil 5x30 OE 100% SYNTHETIC .( After watching YOUTUBE video of Mr. Eben about cold flow comparison of Amsoil and other! Somehow I was convinced and lead to my decision to switch to Amsoil product!) I was not disappointed ! My 2002 Sienna is revitalized and doing fantastic to this day! Thanks Amsoil👍

Just purchased will update review on my next purchase

In my previous experience, it's the best without all the marketing hype, and you can hear the difference in the engine when you use it.

Absolutely pure synthetic oil with a known additive list. This is important to me because I have a 2014 CR-V with 150k miles on it as my spare car. So, when I send the oil to be tested every six months (It's my spare car so don't drive it enough to change the oil even once a year.) it's easy to determine the exact health of the oil and whether or not it's time to change it. Highly recommend.

This oil is great. But a while ago I ordered a case a never got my coolie cups they promised me.

Helps me up over and the mountains everyday for work engines keep running good

I ordered 0w20 and you sent me 5w20. Still used it because I didn’t want to deal with shipping.

Allows the twin turbos to really power up. The Ecoboost motor loves this oil, and at 340,000 miles it’s all that I trust.

I have improved my gas mileage by a bit with changing over to AMSOIL, it’s great!

Been using amsoil for nearly 25 years now. Simply the best oil and lube products on earth. I get more than double the life out of my vehicles and machines that everyone else seems to get.

Top notch oil, made amazing difference in mileage and engine cold start noise, Engine runs smooth and quiet.

AMS oil is a great product and they have shipped super fast to me when I place an order

Before my car at best would get 19mpg now after using AMSOIL 5W-30 high mileage 26mpg. I noticed the car would burn oil, rough housing it 2-2.5 quarts per 5k mile intervals now it doesn't burn anything. I keep recommending AMSOIL to all my friends and anyone because it is the best oil out there. Everyone has converted to AMSOIL and they all claim it's beyond premium.

Simply the best in every way hands down.

I definitely recommend this oil, it has always worked great in my vehicles. I purchase the kits with filter and everything. Never have issues and change oil at 10,000 miles. 2013 Chevy Silverado with 173,000 miles.

Started using Amsoil products in everything from my mower to my atv and sxs as well as all of our vehicles, good price. Great stuff!👍

Good oil. Going to buy again i like the product

This oil is great. I’ve been using this oil in my wife’s car(2011 Mazda 2) for about 20k miles. I did a valve cover gasket on it recently and the inside of the engine looks brand new.
