Always use Amsoil oils

I run amsoil in every engine I own. Cars, mowers, boats, etc… all I will ever use or recommend. Shipping is fast!

I was very surprise as to my truck responded to this oil. My gas mile went up 3 more miles per gallon -13 to 16 . With an oil additive the miles per gallon increase another point (17.5) . I would definitely recommend this oil . I have a 2005 DODGE RAM 1500 with a 5.7.

Keeps truck running like new

Have used Amsoil 5w30 signature series in my truck since it was new. Runs as good today as it did then, I wouldn't use any other motor oil. I use Amsoil in all my engines ( motorcycles, four wheeler, lawnmower, car and truck).

Heard about this being the best, and I think it is. Use this stuff for my 4-wheeler as well. I drive for Lyft and I think AMSOIL has what it takes.

Like all Amsoil product this oil does the job. Just finished a 5500 trip in my 2010 Yukon Denali. The engine used a small amount of oil. I wouldn’t trust any other oil.

Ever since I started using Amsoil signature series, my Q50 runs BETTER!

Have been using this product for many years. I change my oil once per year and the oil works excellent!

I’ve heard great things about Amsoil and decided to use their oil for my next oil change in my 2018 GMC Sierra. After putting a few miles on the truck since the oil change, I swear the truck runs better and smoother. I definitely will buy this oil again for my next oil change.

Befor Amsoil, i used other brands in my family's cars. And let me tell you, there isn't any as good as Amsoil. In my family we own toyotas, Mercedes Benz, Audi, Chevrolet, Nissan, Honda, BMW, Acura and Smart. And evry single one of them uses Amsoil. It made a big difference in all of them. Please give it a try and judge by yourself. 100% recommended!

Great oil .just moved across country and no problems.

I tend to own all of my vehicles long term and always use Amsoil Signature series. My 2001 truck I bought used at 115,000km currently has 378,000km and gets the oil changed every 6 months averaging about 15,000km per change. I also have a 1999 Sunfire that I bought with 66,000Km on it and it's now at 450,000Km and still going strong.

Best oil on the planet !! Using since 1999 on everything that I have that has a motor... Engines are very clean inside ..

Had Amsoil signature series full synthetic since the first oil change. 225k miles and going strong.

Excellent service, with great product, awesome combination

One oil change per year saves me time and money! Love it!

This has been in my 3.5 Expedition for over 100,000 miles and everything is running perfect. Will use it in my new one.

When something is the best in it's field why think about using any other product. Best results for the money. Amsoil only for my vehicles and anyone I talk to I tell about how great Amsoil is!

It feels good knowing you are using the best oil on the market in your prized possession!
