OPERATION
Fuel
NOTICE: Damage to the fuel pump will occur if the snowmobile is operated with
an empty fuel tank. Do not allow the snowmobile to run out of fuel.
Always refuel when the level is low.
For peak performance, Polaris recommends the use of 91 octane or
higher fuel. Although 87 octane fuel is usable, some engine perfor-
mance will be lost and fuel economy will decrease. Do not use lower
than 87 octane fuel. Do not use fuel containing more than 10% ethanol
(including E85).
NOTICE: Operating with obstructed fuel systems will result in serious engine
damage. Perform maintenance as recommended.
NOTICE: Prolonged exposure to petroleum based products may damage paint.
Always protect painted surfaces when handling fuel.
Fuel Level
The fuel symbol and the last fuel bar on the MFD gauge will blink when
the fuel level reaches 1/8th tank. There will be approximately one gallon
of fuel remaining. Refuel as soon as possible. Do not allow the snowmo-
bile to run out of fuel.
Fuel System Deicers
If you use non-oxygenated fuel, Polaris recommends the regular use of
isopropyl-based fuel system deicer. Add one to two ounces per gallon
(8-16 ml per liter) of gasoline to prevent engine damage resulting from
fuel system icing and lean fuel mixtures. Never use deicers or additives
containing methanol. Polaris also recommends the use of Carbon Clean
Plus. See page 141 for the part numbers of Polaris products.
If you use oxygenated fuel containing ethanol, additional alcohol deic-
ers or water absorbing additives should not be used.
