Today’s gasoline breaks down quickly. When it does, it leaves behind a thick varnish-like residue that adheres to the walls of its container, including the inside of the fuel system in your snowmobile. The small passages in the fuel system can become restricted or blocked, leading to all kinds of running quality issues.

Further, gas may have 10%, or more, alcohol, which attracts and blends with water, causing fuel system problems and the breakdown of lubricating mix-oils in 2-cycle equipment. Snowmobiles are especially prone to these fuel problems because the equipment is not run daily, allowing time for the fuel to deteriorate and absorb water.

For best results, avoid alcohol-blended fuels and never use higher-alcohol blends in your equipment. “Premium” fuels are often times not blended with alcohol and are the preferred option for use in season equipment.
