Everyone has there favorites..... I had a problem with penzoil in a boat motor a few years ago and wont touch the stuff again. I use amsoil in everything, my boat, dirt bike, truck, Gf's car, even my 1965 honda 50 runs amsoil and I have never, ever had a problem. Who knows, it all comes down to what you like....
