Customer Ratings & Reviews

Ive got Amsoil in everything from my 87 Bronco to my 06 Expy. Motor oil transmission fluid in both. My wife has the European oil in her Turbo Beetle and my mowers have the 4 stroke small engine oil. I use everything from zrod 20-50 to 5w -40 European turbo safe oil

I use this product and Amsoil 0W-30 in my vehicles. They are both great products.

The wear protection is phenomenonal, the performance improvements are noticeable and the extended drain intervals are what make Amsoil my favorite product. I currently run this oil in a half ton (V8) and SUV (V8) which put between 30000-40000 miles a year each.

after 1 year oil is in better shape in color and overall viscosity that conventional oil i use the recommended amsoil filter with cold winters and hot summers pulling a boat of 5000 saves me money only changing once a year instead of 3 with regular oil

I have been running Amsoil in my vechicles for over 10 years, now I am using 5 W 20 motor oil in my jk which I wheel often as well as daily drive, the oil is great and my vechicle appreciates it.

When I went to all synthetic products on the motor home the transmission stopped slipping and my mileage also improved.

I ran this oil on the 15,000 mile program because I'm on the gas pretty heavy at times. The first cycle went well, but the next cycle I pulled my trailer a lot and the oil was history at 6,000. Truck also had lifter tick at start up when motor was already at running temp. Went back to conventional oil and lifter tick was gone.

Your product have become overpriced and shipping prices are out of control, can't imagine if I wasn't A preferred paying customer...
