Customer Ratings & Reviews

Been a customer for 10 yrs, keep raising prices, I’ll switch to other oils.

Put this in my 2020 Silverado and mileage went up by 2/mpg and truck runs cooler pulling my trailer

Amsoil is very good oil. My cavalier has 295k on the odometer, and I would like for it to last a lot longer.

Please make your 0W40 Signature Synthetic oil available in 5 Quart jugs and not just in 1 Quart bottles.

I've used Amsoil for many years, and it has always performed to the highest standards. I would, and I have recommended its use for any car, truck bike...anything that needs oil, this is the one...Edd

I use this oil in my Dodge Challenger 5.7 HEMI and have had amazing results. This oil makes my car run like a new engine after every oil change. I love it!

Amsoil is simple the best oil to keep your engine running for a long, long time!!!

Just great oil

I have been using Amsoil for may years in various vehicles and now prefer to use it in all of my vehicles.

I use your product in every thing I have that has an engine that requires oil.

I always use the best!

I only use the best!

Ran all the other big brands trying to see which quieted the turbo the best, Amsoil within 500 miles has the car running as smooth as it ever has . 2016 vw jetta

We have been using Amsoil's Signature Series oils for over 20 years. Amsoil has protected our vehicles so well that even after 200,000 miles there has been no engine oil consumption by our cars (5 of them over the years). This being said, we are EXTREMELY disappointed with Amsoil for refusing to manufacture 0w-16 oil in the Signature Series line. Of course the demand for it is not great right now. But for longtime Amsoil customers couldn't they small batches annually for us? Most who require 0w-16 oil, knowing it's limited availability would likely buy an annual supply each year. It's very disappointing for us who have come to depend on the quality of Amsoil lubricants.

My oil analysis prove that this is the best oil money can buy

Great Product, Works well. Very Happy with it.

So far everything is working good. No mpg improvement or anything drastic. As long as it keeps my engine lubricantes and clean then that’s all I ask for. We will see after a few more oil changes, which won’t be for a while using this stuff haha. Never got my free hat with the order though :(

Awesome Product!

This oil, (5w-30) is more recommend than the 5w-20. This has eliminated all the extra motor noises you don’t want, coming from your 5.0 Coyote

It is the best product I’ve ever purchased thank u all for a great lubricant.
