FUEL AND ENGINE OIL
RECOMMENDATION
FUEL
Use unleaded gasoline with an octane rating
of 88 or higher (Research method).
Unleaded gasoline can extend spark plug
life and exhaust components life.
NOTE: If the engine develops some trouble
like lack of acceleration or insufficiency of its
power, the cause may be due to the fuel the
motorcycle uses. In such case, try changing
the gas station to another. If the situation will
not be improved by changing, consult your
Suzuki dealer for its inspection.
OXYGENATED FUEL RECOMMENDATION
(EU)
Oxygenated fuels which meet the minimum
octane requirement and the requirements
described below may be used in your motor-
cycle without jeopardizing the New Vehicle
Limited Warranty or the Emission Control
System Warranty.
NOTE: Oxygenated fuels are fuels which
contain oxygen carrying additives such as
MTBE or alcohol.
