Recommended Gasoline
(EFI Models)

NOTE: The 660 cc models are
not equipped with a fuel designa-
tion connector.
The recommended gasoline to use in
these snowmobiles is 87 minimum
octane regular unleaded, and the
Fuel Designation Connector at the
ECU must be connected. In many
areas, oxygenates (either ethanol or
MTBE) are added to the gasoline.
Oxygenated gasolines containing up
to 10% ethanol or up to 15% MTBE
are acceptable gasolines; however, if
oxygenated gasoline is used, the fuel
designation connector at the ECU
must be disconnected. Do not use
gasolines containing methanol.
! CAUTION
Do not use white gas or gaso-
line containing methanol. Only
Arctic Cat approved gasoline
additives should be used.
! CAUTION
If oxygenated gasoline is to be
used, it is extremely important
that the fuel designation con-
nector at the ECU is discon-
n e c t e d . I f n o t w h e n u s i n g
oxygenated gasoline, severe
engine damage may occur.

NOTE: In order for the ECU to
change modes, the engine must
be OFF when connecting or dis-
connecting the fuel designation
connector.
