If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

immediately wash with soap and
water. Change clothing if gasoline
spills on it.

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 rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems.Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)
