Customer Ratings & Reviews

So far so good the only thing I don't like is when my oil temp gets around 216 deg my oil pressure drops to 31 psi. When I was running pennsoil platinum it would only to 33 psi

Switched to Amsoil in the 08 Grand Marq and 17 Fit last year. Engines run quieter, smoother and can be described as apparently happier to be running on Amsoil. Based on how the Marq is performing with Amsoil and w/200.000+ on the clock, I predict I will get more than the 400,000 I originally expected from that engine.

I absolutely believe AMSOIL is better than any other oil sold to the public.

The best oil out there for keeping your performance vehicles running their best !

As a novice with engine builds we just finished our first mild 350. Amsoil break in oil was our choice to break in the cam but have since ordered 10W30 full synthetic for my daily driver. Been a great experience so far!

This is the best I've ever used. This oil does what it says! I know my truck engine will outlast the truck.

Maybe the best oil I have ever used

The synthetic motor oil is sitting in the garage in the original box it can in, my truck was stolen on the day that the motor oil arrived at my house.

Always very pleased with all Amsoil products I use.

Great value replacement for OEM motor oil.

The best oil for my car and to help with dilution in oil. Recommend Amsoil in general to everyone.

Have used this product since first oil change on my 2019 CrossTrek. No loss of oil, products seems to perform as advertised. I trust the quality of Amsoil.

I'll always shop with then, great oil for a good price.

As with all of the products we have purchased from Amsoil we are very happy this oil for the 2014 GMC Sierra and was delivered to the door next day! We will continue to use Amsoil products and service!

Excellent product

Excellent product

Since making the move to amsoil my 2005 dodge ram pick-up gas mileage has improved significantly ,I couldn't be happier with the performance and would absolutely recommend these products to friends

Engine is super quiet

After changing oil in my 2021 Kia Soul, I noticed right away that the engine was a tick below its usual position on the temp gauge. It didn't seem to run as hot as it did with the original oil that came with the car. I have not seen any oil use with this oil even though the blogs for the kia are stating that the engines tend to use up to a quart of oil between changes. I have 1500 miles on this oil change and running the car in 101 to 115 degrees days in downtown and freeway traffic with no noticeable use of oil. In my opinion this motor likes 10/30 Amsoil and I will continue to use it. I also run it in my motorhome and it has the big ol "workhorse 8.1 liter V8" and again I noticed that it running a noticeably cooler temp after using Amsoil.

Thanks
