How to Improve the MPG for a Snowmobile

During the winter months, many people turn to snowmobiles as an effective cure for cabin fever. Of course, the cure doesn't come without a cost. During periods of high fuel prices, gas mileage is an important concern not only for your car or truck, but for your snowmobile as well. Fortunately, you do not have to sacrifice your snowmobile or your fun. You can improve your snowmobile's miles per gallon and save money by following a few easy steps.

      Operate the snowmobile at lower speeds. Gunning the snowmobile's throttle or holding the throttle wide open will generate more speed, but it will also burn fuel at a higher rate. Slower speeds and steady acceleration will provide better fuel economy for your snowmobile.

      Remove extra weight from the snowmobile. Carrying any additional weight on your snowmobile inevitably reduces its gas mileage. For instance, the weight of an extra passenger or equipment will cause the snowmobile to sink slightly deeper into the snow, thus increasing the burden on the snowmobile's engine. With the need for additional power comes a need for additional fuel.

      Check the fuel lines, fuel tank, fuel filter and spark plugs. Ensure the snowmobile's fuel lines and fuel tank are leak-free. If you own an older snowmobile with a metal gas tank, check for any small dents, as they may be a source for leaks. Check the fuel filter to make certain it is clean and free of any blockages. A dirty filter will reduce the snowmobile's miles per gallon. Old or fouled spark plugs will also hamper the snowmobile's gas mileage.

      Change the engine oil and oil filter. The snowmobile's engine must run at the efficient level possible to ensure good gas mileage. You can help increase engine efficiency by regularly changing the oil and oil filter. Check your owner's manual for the type of oil to use in your specific snowmobile. An annual tune-up of the snowmobile's engine will also ensure peak efficiency and gas mileage.

      Operate the snowmobile only on light snow or on trails where the snow has been heavily packed. Deep, loose snow will increase the resistance against the snowmobile. Therefore, the snowmobile will work harder and expend more gas to cover the same distance in deep snow than in light snow or on well-packed trails.
