FUEL AND OIL
Recommended Fuel
Use regular unleaded gasoline, available from most service stations or
oxygenated fuel containing less than 10% of ethanol or 5% of meth-
anol. The gasoline used must have an octane number (R + M)/2 of 87
or higher.
NOTE:
In most service station pump octane number corresponds to
(R + M)/2 octane number.
CAUTION:
Never experiment with other fuels or fuel ratios. The
use of unrecommended fuel can result in snowmobile perfor-
mance deterioration and damage to critical parts in the fuel sys-
tem and engine components. Do not mistake oil reservoir cap for
fuel tank cap. Oil reservoir cap is identified OIL.
Fuel System Antifreeze
When using oxygenated fuel, additional gas line antifreeze or water
absorbing additives are not required and should be not used.
When using non-oxygenated fuel, we highly recommend the use of
isopropyl base gas line antifreeze in a proportion of 150 mL (5 U.S. oz)
of gas line antifreeze added to 40 liters (10-1/2 U.S. gal) of gas.
This precaution is in order to reduce the risk of frost buildup in carbu-
retor(s) which may lead, in certain cases, to high fuel consumption
or severe damage to engine.
NOTE:
Use only
methyl hydrate free
gas line antifreeze.
WARNING
Always stop the engine before refueling. Fuel is inflammable
and explosive under certain conditions. Always work in a well
ventilated area. Do not smoke or allow open flames or sparks in
the vicinity. Open cap slowly. If a differential pressure condition
is noticed (whistling sound heard when loosening fuel tank cap)
have vehicle inspected and/or repaired before further operation.
Do not overfill or top off the fuel tank before placing the vehicle
in a warm area. As temperature increases, fuel expands and
might overflow. Always wipe off any fuel spillage from the ve-
hicle. Periodically verify fuel system.
