Fuel requirements

EMU41331

Gasoline

Use a good quality gasoline that meets the
minimum octane requirement. If knocking or
pinging occurs, use a different brand of gas-
oline or premium unleaded fuel. Yamaha
recommends that you use alcohol-free gaso-
line (see Gasoline with Ethanol) whenever
possible.
The use of a poor quality gasoline may result
in starting and running problems. If you en-
counter drivability problems, which you sus-
pect could be related to the fuel you are
using, we recommend that you switch to a
recognized high quality brand of gasoline,
such as a gasoline that is advertised as Top
Tier Detergent Gasoline. Failure to comply
with these recommendations may also result
in unscheduled maintenance, fuel system
damage, and internal engine damage.

NOTICE

ECM01981



Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.



Avoid getting water and contaminants
in the fuel tank. Contaminated fuel can
cause poor performance or engine
damage. Use only fresh gasoline that
has been stored in clean containers.

able in the U.S.A. and Canada for use in au-
tomobiles and boats: conventional gasoline
