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, so we encourage the
use of premium fuel when possible. Do not use lower than 87 octane
fuel. Do not use fuel containing more than 10% ethanol (including E85).
Fuel Reserve Capacity (Mechanical Gauge)
There are approximately two gallons of fuel left in the tank when the
mechanical fuel gauge reads RES.
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. See page 111 for the part numbers of
Polaris products.
If you use oxygenated fuel containing ethanol, additional alcohol deic-
ers or water absorbing additives are not required and should not be used.
CAUTION
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.
CAUTION
Prolonged exposure to petroleum based products may damage paint. Always
protect painted surfaces when handling fuel.
