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, Yamaha recommends that you switch
to a recognized high quality brand of gaso-
line, such as a gasoline that is advertised as
Top Tier Detergent Gasoline. NOTICE: Fail-
ure to comply with these recommenda-
tions may also result in unscheduled
maintenance, fuel system damage, and
internal engine damage.
