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. Always use the
premium fuel switch when using premium fuel. Do not use lower than
87 octane fuel. Do not use fuel containing more than 10% ethanol
(including E85)
NOTE: Some engines require premium fuel. See your Owner’s Manual
Supplement.
Premium Fuel Switch
If your Polaris snowmobile is equipped
with a key function to adjust the timing
on the machine as you change fuels, it's
very important to the life of your
engine that you use this feature.
When using fuels with a pump-posted
octane rating of 91 or higher, turn the
key switch to ON/PREM. When the
engine is started, a yellow Premium
Fuel light illuminates on the instrument
panel. When the key is in this position,
the fuel must be a minimum of 91
octane. Return the key switch to the
ON/REG position when not using pre-
mium fuel.
If you're uncertain about the quality or octane rating of the fuel you use,
turn your key switch to ON/REG. The Premium Fuel light will go out.
This setting will adjust the timing of your engine to run on fuels with 87
octane or higher. Polaris does not recommend using fuel with lower than
87 octane. Running your machine on ON/REG will help protect your
engine from damage caused by low octane fuels.
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.
