FUEL AND OIL
Recommended Fuel
Use regular unleaded gasoline, avail-
able from most service stations or oxy-
genated fuel containing a maximum
total of 10% of ethanol or methanol
or both. The gasoline used must have
the following recommended minimum
octane rating.
LOCATION OCTANE RATING
Inside North
America
(87 (RON +
MON)/2)
(1)
Outside North
America
92 RON
(1)
(1)
This is the minimum octane rating
required, if not available, (91 (RON +
MON)/2) or 95 RON (outside North
America)canbeused.
NOTICE
Never experiment
with other fuels. The use of non-
recommended fuel can result in
snowmobile performance deterio-
ration and damage to critical parts in
the fuel system and engine compo-
nents. Do not mistake oil reservoir
cap for fuel tank cap. Oil reservoir
cap is identified OIL.
Fuel Antifreeze Additives
When using oxygenated fuel, addi-
tional gas line antifreeze or water ab-
sorbing 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 150ml(5U.S.oz)) of gas line an-
tifreezeaddedto40L(10.6U.S.gal.)
of gas.
This precaution is in order to reduce
the risk of frost buildup in carburetors/
throttle bodies which may lead, in cer-
tain cases, to high fuel consumption or
severe damage to engine.
NOTE: Use only methyl hydrate free
gas line antifreeze.
Fueling Procedure
WARNING
Always stop the engine before re-
fueling. Fuel is flammable and ex-
plosive 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 differen-
tial pressure condition is noticed
(whistling sound heard when loos-
ening fuel tank cap) have vehicle
inspected and/or repaired before
further operation. Do not overfill
or top off the fuel tank before plac-
ing the vehicle in a warm area. As
temperature increases, fuel ex-
pands and might overflow. Al-
ways wipe off any fuel spillage
from the vehicle. Periodically ver-
ify fuel system.
