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.

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

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

Use this in a 17’ Mustang EcoBoost. I believe the engine is quieter and runs smoother than before the Amsoil 5w-30 Boosted. Car driver is happy also.

As usual. Product has an excellent quality.

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

Outstanding Products And Services

By far the best oil I have used for my Ford Edge. My car never has consumed/burned much oil, but with this oil it is noticeably less and lasts longer. With the Amsoil filter it stays cleaner than any other oil and filter combo I have used.

This is great for the eco boost

It is the best oil that I've used in my vehicle and would recommend to anyone.
