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 113 for the part
numbers of Polaris-recommended products.
If you use oxygenated fuel containing ethanol, additional alcohol
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.
