Poll: Synthetic/Conventional/Blend

I use synthetic Amsoil in everything - race car, tow truck & every day truck, because I've experienced many of it's benefits through the years over conventional lubes. (Engine, trans rear and wheel bearings.) The extra margin of protection gives me peace of mind as well.

Not all synthetics are created equal!
