FUEL, ENGINE OIL AND
COOLANT
RECOMMENDATIONS
FUEL OCTANE RATING
Use unleaded gasoline with an
octane rating of 91 or higher
(Research method). Unleaded gaso-
line can extend spark plug life and
exhaust components life.
If pinking or knocking is experienced,
substitute higher octane grade gaso-
line or another brand, because there
are differences between brands.
(For Canada)
Your motorcycle requires regular
unleaded gasoline with a minimum
pump octane rating of 87 ((R+M)/2
method). In some areas, the only
fuels that are available are oxygen-
ated fuels.
OXYGENATED FUEL
RECOMMENDATION
(For Canada and EU)
Oxygenated fuels which meet the
minimum octane requirement and the
requirements described below may
be used in your motorcycle without
jeopardizing the New Vehicle Limited
Warranty or the Emission Control
System Warranty.
NOTE: Oxygenated fuels are fuels
which contain oxygen carrying addi-
tives such as MTBE or alcohol.
Gasoline Containing MTBE
Unleaded gasoline containing MTBE
(Methyl Tertiary Butyl Ether) may be
used in your motorcycle if the MTBE
content is not greater than 15%. This
oxygenated fuel does not contain
alcohol.
Gasoline/Ethanol Blends
Blends of unleaded gasoline and eth-
anol (grain alcohol), also known as
"GASOHOL'.', may be used in your
vehicle if the ethanol content is not
greater than 10%.
Gasoline/Methanol Blends
Fuels containing 5% or less methanol
(wood alcohol) may be suitable for
use in your motorcycle if they contain
co-solvents and corrosion inhibitors.
3-2
DO NOT USE fuels containing more
than 5% methanol under any circum-
stances. Fuel system damage or
motorcycle performance problems
resulting from the use of such fuels
are not the responsibility of Suzuki
and may not be covered under the
New Vehicle Limited Warranty or the
Emission Control System Warranty.
NOTE:
• T o help minimize air pollution,
SUZUKI recommends that you
use oxygenated fuels.
• Be sure that any oxygenated fuel
you use has recommended
octane ratings.
• If you are not satisfied with the
driveability of your motorcycle
when you are using an oxygen-
ated fuel, or if engine pinging is
experienced, substitute another
brand as there are differences
between brands.
CAUTION
Spilled gasoline containing alco-
hol can harm your motorcycle.
Alcohol can damage painted sur-
faces.
Be careful not to spill any fuel
when filling the fuel tank. Wipe
spilled gasoline up immediately.
ENGINE OIL
Oil quality is a major contributor to
your engine's performance and life.
Always select good quality engine oil.
Use oil with an API (American Petro-
leum Institute) classification of SF/SG
or SH/SJ, or with a JASO classifica-
tion of MA.

SAE Engine Oil Viscosity
Suzuki recommends the use of SAE
1 0W-40 engine oil. If SAE 10W-40
