OPERATION
Fuel
POLARIS recommends the use of 91 octane or higher fuel. Although 87
octane fuel is usable, some engine performance will be lost and fuel
economy will decrease. Do not use lower than 87 octane fuel. Do not
use fuel containing more than 10% ethanol (including E85).
NOTICE: Operating with obstructed fuel systems will result in serious engine
damage. Perform maintenance as recommended. Prolonged expo-
sure to petroleum based products may damage paint. Always protect
painted surfaces when handling fuel.
This snowmobile is equipped with a feature that allows you to select the
proper calibration map for the fuel available in your region. Fuel resis-
tors must be changed when non-ethanol fuel is used.
NOTICE: Engine damage may occur if ethanol fuel is used after setting up the
vehicle for non-ethanol fuel use. Depending on your model, always
reinstall the ethanol fuel resistor or disconnect the mode change wires
before operating with ethanol fuel. When in doubt about fuel quality,
always use the ethanol fuel resistor or unplug the wires.
Fuel Resistor
The factory-installed fuel resistor is for the
use of ethanol fuel. If operating with non-
ethanol fuel becomes necessary, always
install the non-ethanol fuel resistor. The
non-ethanol fuel resistor is provided in the
tool kit.
