Superior product been using in my vehicles for many years also in all my lawn equipment. I noticed ever since I've been using this product my lawn equipment vehicles run better smoother and less maintenance better gas mileage Great amazing awesome product.

Car loves it

I am using this oil in a 6.4 L hemi on engine start up. The engine has no lifter noise with this oil in it. as other oils that I have used in the past which I will not mention

Car engine sounds quieter

It gets and stays hot where I live. It is also dusty much of the time. So I have to know my engine is getting what it needs to prolong life. Ever since I watched Gail Banks three part tour of the Wisconsin plant I have come to know that I am using the best lubrication in all my vehicles including a fifteen year old bagger. Using Amsoil is the poor man's insurance policy!

The 5W20 Signature Series oil always performs flawlessly.

I always thought that Mobil 1 or Royal Purple was the best. I started hearing about Amsoil from the YouTube channel RainmanRaysRepairs. After that, I did some research which included another channel Project Farm that tests all kinds of stuff. After that, I pulled the trigger on my next oil change in my daily driver. I gotta admit, my engine feels pretty slick. My throttle response feels sharper too. Time will tell, but worth every penny, so far.

I only use this oil in my promaster. The technology in the oil is the best defense to engine life and performance !

The best of the best oil, Amsoil

Incredible protective properties motor oil that is great for turbocharged Japanese vehicles.

Unbelievably long lasting motor oil that is great for use in heavy use fleet vehicles.

I have two turbocharged vehicles, and this is the only oil I use in either one of them. Neither vehicle burns oil, and they run the same as they did when new.

I've been using Amsoil in my 2014 Jeep Wrangler Unlimited for years. It still runs great at 185,000 miles and uses no oil. I recommend this oil.

Did my first oil change on my 22 392 with this oil. Noticed better idle better mph and better engine speed.

So far so good but only time will tell.

Honestly, just buy it....you won't regret it! Join the Amsoil Nation!

Best product I've used. Highly recommend!

Great product, highly recommended

Fast shipping, great product, will be using for many oil changes to come.

I have been using AMSOIL since about 1978. Never had a failure or a reason to complain. Using it now in my two monstermobiles: My Shelby Cobra, and my Toyota Scion Xb.
