OPERATION

Engine Break-In

Oil Injection System

CAUTION

Check the oil tank level often during the first tankful of fuel. If the oil level doesn’t go down, contact your dealer immediately.

Always fill the oil reservoir when refueling. Fuel-to-oil mix ratios are controlled by the oil pump and correspond to the engine’s RPM and throttle valve opening.

Variable Exhaust System

All snowmobile engines equipped with variable exhaust valves should use VES 2 Cycle Oil (see chart on page 77).

Lubrication

The only source of engine lubrication for your engine comes from lubrication added to the fuel and oil injection systems. Use only Polaris products. We are continuously testing lubricants and provide the highest performance products available for your engine. Please refer to the table below to determine the preferred and acceptable oils for use in your engine.

Never mix other brands of oil. They may 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.
