55 OPERATION Fuel Premium Fuel Switch If you’re uncertain about the quality or octane rating of the fuel you use, turn your key switch to ON/REG. The Premium Fuel light will go out. This setting will adjust the timing of your engine to run on fuels with 87 octane or higher. Polaris does not recommend using fuel with lower than 87 octane. Running your machine on ON/REG will help protect your engine from damage caused by low octane fuels. Fuel Reserve Capacity (Mechanical Gauge) There are approximately two gallons of fuel left in the tank when the mechanical fuel gauge reads RES. Fuel System Deicers If you use non-oxygenated fuel, Polaris recommends the regular use of isopropyl-based fuel system deicer. Add one to two ounces per gallon (8-16 milliliters per liter) of gasoline to prevent engine damage resulting from fuel system icing and lean fuel mixtures. Never use deicers or additives containing methanol. See page 110 for the part numbers of Polaris products. deicers or water absorbing additives are not required and should not be used. Prolonged exposure to petroleum based products may damage paint. Always protect painted surfaces when handling fuel. CAUTION |
