Customer Ratings & Reviews

I have used this in my 08 Silverado 2500 6.0 Vortec for years . I lost a radiator hose on the interstate and didn't realize for quite awhile . Pulled over ,called my mechanic and explained that I had just toasted my engine . It was HOT ! He called me the next day and explained that with 200k the compression was great in all 8 cylinders and asked ,what kind of oil do you use? When I explained that I have always used AMSOIL, his response was no matter what the cost it just paid you back and come get your truck . 250k now no problems

Love the products. This time it took forever to get my oil I started to get frustrated with ups.

Have used Amsoil for years. I’m very satisfied with the products!

I've had two oil changes using OE and it works just as well as the XL or Signature.

Both of my Subaru’s take full synthetic 0-20. They purr with this oil and have had zero issues with them.

Do my own oil changes saved over a hundred dollars on my 2017 ZL1.

What I like about this oil is you can tell from the very first time you use it that there is a difference in the way your engine starts on cold mornings and the way it just runs. I highly recommend amsoil and use it in everything I own.

What I like about amsoil is you can tell a difference with your vehicle the very first time you use it. Makes a big difference in the way my Durango runs and starts on early cold mornings.

It's a high quality product for the price and the shipping is very quick.

Excellent engine oil. My cars start a lot better now in the Minnesota cold weather.

I have 2 honda crvs. Since I started using amsoil oil. My engines are a lot better now. I love it.

The best oil on the market.

Great oil, long time amsoil user , has out performed all other competitors and maintains viscosity throughout oil life !

Great product use on my classic car as well.

This is the finest product I have ever used, and my distributor rep is the best.

Great product, never had any issues and we have some pretty extreme weather patterns here. Because the oil is fairly inexpensive I change with shorter intervals but based on what I've seen come out I have no problem believing the claims about Amsoil's synthetic line ups.

My 02 Chevy Ext. Cab has 431,135 actual miles on the 5.3 motor and still running fine. I give all the credit to this product for the longevity life it’s produced in my ride.

Used this as spec'd for a 2015 Chevy Malibu and it works great, knowing it is much higher quality than the oil change places and cheaper for my client, it is a win win. Having the confidence it will run the whole OLM cycle with ease really reduces my risk as a business owner.

This stuff works amazing, I have a JDM 1999 Mitsubishi Legnum Twin Turbo and it just works so nicely in my car. I will 100% use this product again and would definitely recommend!
