OPERATION Fuel Your POLARIS engine is designed to run on 87 octane non-oxygenated or 89 octane oxygenated pump gasoline. There's a great deal of variability in the quality of the 87 octane gasoline available across the country, so we encourage the use of premium fuel when possible. Do not use fuel containing more than 10% ethanol (including E85). NOTICE: Using fuels with a lower than recommended octane or operating with obstructed fuel systems will result in serious and costly engine damage. Always use the recommended fuels for your machine. 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 98 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. Fuel Valve Turn the fuel valve clockwise to OFF to shut off the fuel supply. Turn the valve counter-clockwise to ON to turn the fuel supply on. OFF ON 52

OPERATION
Fuel
Your POLARIS engine is designed to run on 87 octane non-oxygenated
or 89 octane oxygenated pump gasoline. There's a great deal of variabil-
ity in the quality of the 87 octane gasoline available across the country,
so we encourage the use of premium fuel when possible.
Do not use fuel
containing more than 10% ethanol (including E85)
.
NOTICE:
Using fuels with a lower than recommended octane or operating with
obstructed fuel systems will result in serious and costly engine dam-
age. Always use the recommended fuels for your machine.
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 98 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.
