OPERATION
Fuel
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).
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 112 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.
CAUTION
Operating with obstructed fuel systems will result in serious engine damage.
Perform maintenance as recommended.
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.
Prolonged exposure to petroleum based products may damage paint. Always
protect painted surfaces when handling fuel.
