While reformulated gasoline is very similar to conventional gasoline, there are several very important differences. Because of these differences it is likely that your snowmobile will need to be recalibrated. Recalibration can be done as part of a tune-up by your dealer. For further details please check with your dealer. Use good tank management techniques.
All gasoline has a limited storage life and reformulated gasoline is no exception.
Therefore, when storing your snowmobile for more than 60 days, make sure that the gas tank is completely empty, regardless of which type of gasoline you are using. Also it is a good idea to remove any gasoline in the fuel system by operating the engine until it stops. Taking this precaution will minimize the risk of fuel breakdown when you store your snowmobile for long periods in the off-season. Be aware of what type of fuel you are using when adding fuel line deicers. Depending upon what type of reformulated gasoline you are using, you may not need to add a fuel line deicer.
