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!!

I love the fact I don't have to guess using there vehicle selection process. My oil change was really easy.

I use to find other manufactured 5W50 full synthetic oil at my local auto parts stores, but no longer. Glad I checked the Amsoil website. 5W50 gives my '73 455 Pontiac immediate lubrication on cold start then thickens up just right when driving it hot. Very glad I found it. I will be purchasing Amsoil always for this vehicle and my boat; which I take out onto Lake Superior. So please do not stop making it. The website, purchase, delivery were all good experiences.

I've been using different Amsoil oil for my car my Harley, Amsoil technologies are specialized in oil quality. I drove one of my car for over 300km the compression was still in the 95% spect. The only oil I trust is Amsoil they test there oil on a third-party for velocity and the result are provend top quality.

Trust only Amsoil products for all my vehicles. Motorcycles, quads, snowmobiles, truck and cars. They all get the Amsoil treatment!

Change over all my autos over to Amsoil this year. Working great!
