Customer Ratings & Reviews

I only run Amsoil in my vehicles. I have never had a failure due to oil-related parts! Amsoil is the best protection. I've been using it for about 30 years now in all of my vehicles.

Aaaaaa+++

I run Amsoil in everything I own, from my Duramax to my ATVs. it has never let me down.

We have a fleet of trucks in our construction business and wouldn't think about using any other oil.

I have a 2003 S10 Xtreme pickup with the 4.3 V6 engine that is driven two to 3 thousand miles a year. Need a top quality oil that will be changed once every year. Amsoil Signature fits that need.

Great product will always use . Don't understand but cars just seem to run better . Enough Said

I use this in a 2013 Toyota Prius and it is great. Best oil on the market.

in my 2018 Triumph Motorcycle

Works like it should

I use this in my truck and my boys truck. I trust its longevity. I wish the price was better.

Perfect

I have used amsoil scene 1970 never lost a motor trany or rear end with amsoil and I driven them hard raced it dragracing and rounded rounder now I have a ffg fleet of Van's running 350000 miles a year and change it every 35000

Excellent Product !!! get great fuel economy

It is a great product that is working real well in my truck

I tell people just try it and you'll see how well it protects your engines. I use it in my vehicles and my personal vehicle a 2014 Expedition has 76000 miles and doesn't use a drop of oil between oil changes once a year, about 18,000 miles. How can you not use a product that keeps you vehicle running great. My family has been using this oil for a long time and a wide range of vehicles. 2018 Shelby 350GT, the Expedition, 2000 Mustang V6, GMC 4 cylinder with over 122000 miles, boats I used to own. If it used oil I put the signature oil in it. Including my Toro zero turn that I have been using for 12 years and it still uses no oil between oil changes once a year.

Worth the money

Use this oil in my Ford Flex, I have always used Amsoil and am very very happy with its performance. Great product.
