Customer Ratings & Reviews

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.

Best oil I have use for my car and the last brand i will ever use

The best engine oil period.

The best car oil. Improved MPG By 4 miles.

I will not put any other oil in my cars.

Want the best, buy AMSOIL

I use the Signature series oil in a broad range of vehicles, from my 04 Titan to a 2018 Chevy cruise. I love the extended change intervals and the security of knowing that my vehicle is protected. You cannot beat the customer service either.

Best oil you can run. Period!

Need this for my Toyota, I commute for work and this is a better price product for the amount of mileage it is good for.

I have a 2013 Subaru Impreza bought it used from the dealership in 2017 with 69,000 miles. Two weeks after that I started using amsoil motor oil and filter.

Great product.

The Best oil, period!
