marvel mystery oil is my fav. Use it in oil changes and gas tank. Seafoam works when it need a more drastic cleaning like carbs sticking. Love it on old bikes or cars that haven't run in a while. My secondaries where sticking but have gotten A LOT better after 3 tanks with seafoam.

btw for extra zinc doesnt do much unless its solid lifters and cam. Also rotella stopped doing zinc additive. Valovline racing is the only one left besides specialty oil like brad penn. I have to use it in my flathead.
