Great quality oil. Project Farm approved!

great product will continue to use.

I've been running the Amsoil for only about 2 months in a Gen 5 4Runner and only really city miles. BUT after 4 years of using Royal Purple, which I have had no real complaints with, I tried teh Amsoil and have seen a difference. Not a huge amount maybe, but big enough for someone who does their own oil changes and was using Royal Purple. It's a big enough difference for me. Less knocking during acceleration and just smoother in general. I'll see how it does since it's recommended for at least two oil changes....

Amsoil has always been good to me. I change my oil every 5000 miles on my motorcycle. Also on three of my vehicles. Great products.I like their gun cleaning solvents also.

The name speaks for itself. Proven and tested (follow the science) to be a top notch motor oil. Its all I use in my street rod and daily driver.

My engine is immortal. My oil slightly ambered yet stil tacky and the American is only because of Amsoil too cleaning performance and the engine was cleaned with sea foam and drained but had sticsion build up some internal on engine now it’s shiny clean. Amsoil is the best

i've been using Amsoil for a long time on my semi truck and i like it ,then i decided to use it on my pick up truck too . So far one of the best

Using amsoil for years with no issues. All my vehicles average 400000miles with no engine or transmission issues.

After changing to this oil my mpg improved by 1mpg. This is the best oil I found with all the research I done. I picked this as I do a lot of off and on of the engine and want the best protection of the start up of the engine where most wear is done.

Since changing to this oil, my Suburban with 110k seems to run quieter and the knock my datalogger was seeing doesn't show up as often. I am pleased with this oil so far, just wish it was not quite so expensive. Highly recommend.

Changed from semi-synthetic to Signature Series 5-20. This oil definitely helps my truck start better in cold weather and I can tell the internal parts get oil faster as well! Great product! 5 ⭐️

what can i said its the best thing out there period!!

Just having Amsoil in my truck is a huge relief knowing that the engine is protected with the Industries top leading oil hands down.

Excellent product! I changed from using mobile one for 2 years, and immediately I felt the difference in how the car ran overall. I have an rsx type s, so it’s high revving. Before it almost felt like it was struggling, but now it drives at 3-4 thousand rpm like its supposed to. You can feel how free the engine operates. Thankyou amsoil!!
