There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E0, E5, E10
are all acceptable). Gasohol containing
methanol is not recommended by
Yamaha because it can cause damage
to the fuel system or vehicle perfor-
mance problems.
