FUEL SYSTEM DEICERS

If you use non-ethanol fuel (sometimes labeled "non-
oxygenated"), POLARIS recommends the regular use of
isopropyl-based fuel system deicer. Add 1-2 ounces per
gallon (8-16 ml per liter) of gasoline to prevent damage
resulting from fuel system icing. Never use deicers or
additives containing methanol. POLARIS recommends
the use of Carbon Clean.
IMPORTANT
If you use fuel with up to 10% ethanol (sometimes
labeled "oxygenated") do not add deicers or additives
that contain any form of alcohol. Adding deicer to
oxygenated fuels could result in severe engine
damage.
