Customer Ratings & Reviews

I started using this oil as a cheaper alternative to the Amsoil signature because my wife currentyonly drove her car less than 1000 miles per year.

Been using Amsoil in all my vehicles since the 80's. All of my engines performed excellent on Asmoil. They purred like a kitten! Oil analysis showed below average wear numbers. People say Amsoil is expensive but they neve actually bought it. With the preferred member account Amsoil is less expensive than any full synthetic oil out there except for the cheaper W oils in the store. A win win!

This oil is the best on the market bang for buck,engine is cleaner and quieter ITS THE BEST AS ALL AMSOIL OIL IS

Use this oil in our motor home, three cars, it's just awesome! We live in Anchorage, Alaska, and the cold winter starts are great-we don't hear any knocking when we first start the vehicles in the morning, and yes we do use the motor home in the winter to go snowmobiling-and the temperature at night can go low as -30 degrees (it did happen), the motor home started with no noise coming from the engine-quiet. As to other conventional oils you would hear cold oil knocking until until the oil warms up, NOT AMSOIL!!! And the mileage-we saw an increase in miles to gallon ratio. I'm will always stick to AMSOIL!!!

I appreciate the quick response on the shipping on all products received. I use this oil in my 1991Mazda Miata. I have now started using it in the Chevrolet 2500 HD pickup.

My pickup truck runs much better
