OPERATION
Fuel
For peak performance, Polaris recommends the use of 91 octane or
higher fuel. Although 87 octane fuel is usable, some engine
performance will be lost and fuel economy will decrease. Do not use
fuel lower than 87 octane.
CAUTION
Operating with obstructed fuel systems will result in serious
engine damage. Perform maintenance a s 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.
Fuel L evel
The fuel symbol and the last fuel bar on the MF D 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 snowmobile 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 milliliters 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 Pl us. See page 111 for the part numbers of Polaris
products.
If you use oxygenated fuel containing ethanol, additional alcohol
deicers or water absorbing additives should not be used.
