OPERATION
Engine Break-In
Oil Injection System
Always check and fill the oil tank when refueling. See page 59.
Oil Recommendations
This snowmobile is equipped with a variable exhaust system (VES).
Engine lubrication comes from oil added to the fuel and oil injection
systems. Polaris recommends the use of VES II 2 Cycle Oil for this
engine. See page 113 for the part numbers of Polaris products.
Never mix brands of oil. Serious chemical reactions can cause injection
system blockage, resulting in serious engine damage. Oils may also be
incompatible and the result could be sludge formation, filter blockage,
and reduced cold weather flow rates. All Polaris oils are compatible
with each other.
CAUTION
Serious engine damage can occur without the proper lubrication. Check the
oil tank level often during the first tank of fuel. If the oil level doesn't go down,
contact your dealer immediately.
