Use this in all my GM vehicles that require 5W.

Using this in all my imports that require this weight. Good OE replacement.

I became a preferred member of AMSOIL in 2009 when I stopped by their booth at the Sturgis Motorcycle Rally. American made and owned. They offered oils for both my GAS and DIESEL vehicles. I now have two diesel vehicles and the motorcycle. I buy this oil for my Chevy Cruze Diesel and it's been fantastic.

JUST PUT OIL IN AND RUNNING GREAT! WILL GIVE ADDITIONAL REVIEW AT 4000 MILES FROM NOW!

Its good.

Just like all of the Amsoil products it is excellent quality with super support!!!

I changed from signature to OE because I want to still do 6 month oil changes. Truck engine was switched to Amsoil after 1000 miles. Engine runs smoothly like ball bearings on glass. 2021 Ford fi50 5.0 coyote

The price is really what drew me to this one. I have seen so many videos on how AM soil makes their products. From what I’ve seen, it makes them a company that I want to support.

Great oil seems like it gives my truck more power.

Excellent product

great product

I know this oil, for use on working cars, I have not used it on my personal one yet!

After great lengths of research I found that Amsoil 100% Synthetic Oil beat the competition in quality testing. I really like that they give you an actual gallon of oil , not 5 qts. Most smaller cars today only use 4 qts. I recommend their product!

I have used this oil in my truck after the first 3000 mile oil change changed every 5000 mile I have 292000 on it as of 09/24/2022. I have not done anything to the truck at this time.

Since i started using amsoil the ticking noise fro the valves is gone. The engine runs real good now. Thanks for excellent product.

Since i started using amsoil in my Honda Crv, it is running a lot better.

Used it on my 2011 Escalade Ext and the difference was amazing. The truck performance was noticed from the start of the engine.

This oil came recommended for the particular engine in my daily driver that I drive about 90 miles a day with. This being the first time I have ever used a synthetic oil,I tried it, and am pleased with it. I am on the third change with it at 5K mile intervals. It seems to hold up very good, over all , it gives me confidence that I am running the right oil and will continue to.

Use it in all my equipment, cars, trucks & diesel tractors

I have been using this oil in my 2019 Santa Fe since it was brand new. When the valve cover was replaced, the engine looked brand new inside. Switching my Genesis over next oil change as I just bought it.
