Fuel Recommendations
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.
600 IQ Racer Fuel
Always use premium non-oxygenated (92 octane) fuel.
600RR 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).

Fuel System Deicers
When using non-oxygenated fuel, use an isopropyl-based fuel system
deicer. Add one to two ounces per gallon (8-16 ml per liter) of gasoline
to prevent engine damage resulting from fuel system icing and lean
fuel mixtures. Never use deicers or additives containing methanol.
Polaris also recommends the use of Carbon Clean Plus. See page 106
for the part numbers of Polaris products.
NOTE: When using oxygenated fuel containing ethanol, additional alcohol
deicers or water absorbing additives should not be used.
