Engine Break-In OPERATION Oil Injection System CAUTION Serious engine damage can occur without the proper lubrication. 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 We recommend the use of Polaris VES II 2-cycle oil in all snowmobile engines equipped with variable exhaust valves (see chart below). Oil Recommendations The only source of engine lubrication for your engine comes from lubrication added to the fuel and oil injection systems. We highly recommend the use of only Polaris products. We're continuously testing lubricants and provide the highest performance products available for your snowmobile's engine. Refer to the table below to determine the recommended oils for use in your Polaris snowmobile. Never mix brands of oil. Serious chemical reactions can cause injection system blockage, resulting in serious engine damage. They 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.
