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 different brand of gasoline or premium unleaded fuel. If unleaded gasoline is not available, then leaded regular gasoline can be used.
If leaded gasoline is usually used, engine valves and related parts should be inspected after every 300 hours of opera- tion.

Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing meth- anol. 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 Yamaha because it can cause fuel system damage or engine performance problems.
