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
Yamaha because it can cause fuel system
damage or engine performance prob-
lems.
