E EMU00018 GASOLINE (PETROL) Recommended gasoline: Regular unleaded gasoline with a minimum octane rating of 86 (Pump Octane Number) = (R+M)/2 If knocking or pinging occurs, use a differ- ent brand of gasoline or premium unlead- ed fuel. If unleaded gasoline is not avail- able, then leaded regular gasoline can be used. EMU00027 Gasohol There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing ethanol can be used if ethanol content does not exceed 10% and the fuel meets minimum octane ratings. Gasohol containing methanol is not recommended by Yama- ha because it can cause fuel system dam- age or engine performance problems.
