OPERATION
Fuel
The fuel used in your Polaris engine is as important to engine life and
performance as the lubricant used.
Most Polaris engines are 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.
NOTE: Some Polaris snowmobiles require premium gasoline. Check
your Owner’s Manual Supplement to determine what type of fuel your
machine requires.
Premium Fuel Switch
Some Polaris snowmobiles are
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.
Most high performance machines
require the use of premium fuels.
Substituting other fuels may cause
engine damage.
Premium Fuel Setting
Regular Fuel Setting
Using lower than the recommended octane fuels or operating with
obstructed fuel systems will lead to costly engine damage.
