FUEL AND OIL

Recommended Fuel

Vehicles with Valid Warranty (Pre-Heat Switch Disabled)
Use super 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
91 or higher.
NOTE: In most service station pump octane number corresponds to
(R + M)/2 octane number.
Vehicles without Warranty (Pre-Heat Switch Enabled)
Racing fuel with an octane number (R+M)/2 of 108 and more.
All Vehicles
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.
Always stop engine before refueling. Open cap slowly. If a dif-
ferential pressure condition is noticed (whistling sound heard
when loosening fuel tank cap) have vehicle inspected and/or
repaired before further operation. Fuel is flammable and ex-
plosive under certain conditions. Never use an open flame to
check fuel level. Never smoke or allow flame or spark in vicin-
ity. Always work in a well-ventilated area. Never top up the fuel
tank before placing the vehicle in a warm area. As temperature
increases, fuel expands and may overflow. Always wipe off
any fuel spillage from the vehicle.
Fuel System Antifreeze
NOTE: Fuel antifreeze may add alcohol to fuel which may lead to
disqualification by technical inspection after the race.
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 iso-
propyl 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 frozen carburetor(s)
which may lead, in certain cases, to high fuel consumption or severe
damage to engine.
IMPORTANT: Use only methyl hydrate free gas line antifreeze.
