High quality lubrication at a competitive price.

Great oil for my 2015 gmc 2500 6.0L gas

In my truck

Excellent service and product!

I use them in our Toyota vehicles, living in a cold climate, I am confident that they give our vehicle the protection needed during cold starts

Only the best for my street car. I get on average an extra 2 MPG in every car I have put it in.

I'm going to stick with the product.

To make money you have to save it!! Buy the best forget about the rest!!

Great product but the cost is too high

Using it to keep my van going as long as possible.

I have a few vehicles that use AMSOIL oil. Great product and price.

Excellent oil for my 2008 Sequoia and 2013 Subaru Legacy.

I've been using Amsoil products since shortly after they hit the market, and have never had a regret. It's the best of the best. I've never had any kind of failure in any engine that was using Amsoil, even though I sometimes went over the recommended mileage or time limit. My first usage was in motorcycles like the old Honda CB-750F, etc. many decades ago. Back then, the oil filtration systems were poor at best and with conventional oil they became very dirty and gummy inside. Once I switched the first one to Amsoil, and ran if for a long duration before checking the oil, I was shocked to find the oil up in the valve train pristine clean with no gumming, etc., and I was hooked. And, everything I used Amsoil in returned better performance and RPM increase to the point that it had to be turned down. There is no better lubrication product on the market......period.
