Fuel Recommendation
For peak performance, POLARIS recommends the use of 91 octane fuel
or higher, with no ethanol. Although 87 octane fuel is usable, some
engine performance 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. Never use E85 fuel in your snowmobile
.
NOTICE:
Operating with obstructed fuel systems will result in serious engine
damage. Perform maintenance as recommended.
Prolonged exposure to petroleum based products may damage paint.
Always protect painted surfaces when handling fuel.
Fuel System Deicers
If you use non-ethanol fuel (sometimes labeled “non-oxygenated”),
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 damage resulting from fuel system icing.
Never use deicers
or additives containing methanol.
POLARIS recommends the use of
Carbon Clean. See page 110 for the part numbers of POLARIS prod-
ucts.
If you use fuel with up to 10% ethanol (sometimes labeled “oxygen-
ated”) do not add deicers or additives that contain any form of alcohol.
