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.

I've been using this oil for years. Nothing compares to Amsoil.

I have been using Signature Series motor oils in all of my vehicles for 30 years or more. My only complaint has been that it took my 68 Chevy C-10 about twice as far before it would warm up to full operating temperature! My engines stay clean, even though I only change my oil in April of each year.

Working great in a modified and supercharged Hemi 5.7L. We switched over to AMSOiL 0W-40 after the initial break in and plan to continue with AMSOiL 0w-40 in this application.

Best synthetic oil on the market.

Used it in motorcycles, tractors, trucks, lawnmowers and cars for 25+ years. Chg interval 1 year or 25k miles on cars and trucks, 200k or above was easily attained, 300 plus on 2 trucks with no engine repairs.
