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).
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.
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.
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.
