it's the best engine runs very good

I have been using Amsoil products for a few years and am completely satisfied with the quality and performance of their products.. Thank you, team Amsoil, and keep up the good work.

Since the first change oil i made with AMS oil i notice the engine of my car is more quiter than before and also gets more mileage than my older engine oil i totally 100% recommend to all my friends👍👍👍

I have been using Amsoil products now for about 4 years primarily in my wife's Subaru. I use Amsoil engine oil and the CVT oil for the transmission and honestly the CVT oil cost me less than the CVT oil from Subaru. The only reason I don't use Amsoil in my other vehicles is because they are all older and they all use oil but for newer vehicles it's the best thing out there.

I haven’t found a product that holds up to the extreme conditions of a direct injection, turbocharged engine. Signature series oil retains its ability under high heat to provide superior protection. Lesser oils evaporate and shear under pressure, oil is inexpensive compared to an engine rebuild. I can’t recommend this product more.

Switched to this in one of my vehicles, great oil, stays cleaner longer than oem oil

Great oil, the Best!!!! Engine run smoother, A++++

it's the best

I won’t put anything else in any of my cars. Always works flawlessly. Nothing else needs to said because it just works. Worth every penny.

The product's from amsoil are the best in my opinion. I run it in all three of my vehicles.

Best oil on the market. Worth every penny. My grandfather used it and got me to use it. Glad he did.

Simply the best oil that you can put in your engine.

Used AMS oil for years, so has family! Never been disappointed!

I run this oil in my personal truck Keeps her purring

I have always wanted to use the best products available. From everything that I have watched, read, or heard, Amsoil is the best product. I have had no problems with my 2023 Ford Coyote engine. In fact, an individual that is a car enthusiast wants to buy my Coyote in the future. He knew that I was using Amsoil in it now. He wants to replace his older Coyote in his coupe. Sounds like a resounding referral to me.

I use amsoil in my c7 Corvette and thought I'd try mobile 1. The amsoil gave me more miles between oil changes then the mobile 1. 7200 for the amsoil and only 3800 for the mobile 1. I'm sticking with my Amsoil 👍

The glued on seal needs to be removed, pieces of this seal can come off and go into your engine while changing oil. Requiring you to filter the oil when filling the engine. This seal is not on the quart bottle, I will be buying quarts from now on.

I have not put this particular oil in my vehicle yet, I have used Amsoil in previous vehicles that I owed and I was very happy with the performance of the vehicle while using this oil. I know it costs a little more, but I think the results speak for the product.
