Fuel System Antifreeze
When using oxygenated fuel, additional gas line antifreeze or water
absorbing additives are not required and should be not used.
When using non-oxygenated fuel, we highly recommend the use of
isopropyl base gas line antifreeze in a proportion of 150 mL (5 U.S.
oz) of gas line antifreeze added to 40 liters (10-1/2 U.S. gal) of gas.
This precaution is in order to reduce the risk of frost buildup in carbu-
retor(s) which may lead, in certain cases, to high fuel consumption
or severe damage to engine.
NOTE: Use only methyl hydrate free gas line antifreeze.
Recommended Oil
CAUTION: Use only injection oil that flows at - 40°C (- 40°F). Do
not mismatch oil reservoir cap with fuel tank cap. Oil reservoir
cap is identified OIL.
Oil is contained in the injection oil reservoir.
Use only two-stroke engine injection oil sold by authorized SKI-DOO
dealers.
