Can i safely add stp or another viscosity booster to the motorcycle oil in my automatic clutch atv?

No! Don't add any additives to your oil unless they are specifically made for motorcycles... Even if they are motorcycle specific I would be a little wary.


Motorcycle/atv engines are different than car motors since the same oil lubes the motor and the clutch.


Use a quality oil and change it when your supplsed to and theres no need for any additives.Can i safely add stp or another viscosity booster to the motorcycle oil in my automatic clutch atv?
it would be a very bad idea. if u want to wind up having to have the clutch rebuilt way before its time, go for it....but it would be a very expensive bill.
