AMs OIL???
Amsoil makes a quality oil. For the price though, a product like mobil 1 is just as good and available at wally world. If you want to get into the upper level products Redline and Motul are some of the best ester(poylol ester to be exact) motor oils money can buy. Are they needed? Depends on what you are doing with your setup. Most will get by fine with a modern conventional oil of proper viscosity.
