??? I just dont understand why so many people think AMSOil is THE oil to get. Everyone thinks the racers use it well my brother is a pro series snowmobile drag racer and he says everyone uses regular oil or they premix it with there fuel. Also he says that the fuel is what really matters (they run 92 octane with a 5% oxidation for quick burn). Not saying its a bad oil, its actually a very good oil. Also i know it keeps your valves clean. But Cats new synthetic is just as good. Now tell me is it just the price that matters? ???
