ven more than the gas in your car, the gas in your boat needs special care to keep your engine running at peak performance. Gasoline begins to go bad within a few weeks. When left untreated, some of the fuel components begin to oxidize and form a gum-like substance, which settles in fuel lines and tanks, carburetors, and injectors. When you try to burn this fuel, deposits can form in the combustion chamber. Over time, these deposits build up and reduce your engines performance.Fuel additives keep your fuel optimized, protect your fuel system, and remove any leftover deposits.
