All Summit 800 HO and 600 HO SDI Engine Equipped Models

or oxygenated fuel containing less than 10% of ethanol or 5% of
methanol. The gasoline used must have an octane number (R + M)/2
of 91 or higher.
All Models
NOTE: In most service station pump octane number corresponds to
(R + M)/2 octane number.
CAUTION: Never experiment with other fuels or fuel ratios. The
use of unrecommended fuel can result in snowmobile perfor-
mance deterioration and damage to critical parts in the fuel sys-
tem and engine components. Do not mistake oil reservoir cap for
fuel tank cap. Oil reservoir cap is identified OIL.
WARNING
Always stop the engine before refueling. Fuel is inflammable
and explosive under certain conditions. Always work in a well
ventilated area. Do not smoke or allow open flames or sparks in
the vicinity. Open cap slowly. If a differential pressure condition
is noticed (whistling sound heard when loosening fuel tank cap)
have vehicle inspected and/or repaired before further operation.
Do not overfill or top off the fuel tank before placing the vehicle
in a warm area. As temperature increases, fuel expands and
might overflow. Always wipe off any fuel spillage from the ve-
hicle. Periodically verify fuel system.
