Small engines are especially susceptible to ethanol problems such as gum deposits that clog carburettors, making engines difficult to start and run rough. 
Star Tron Enzyme Fuel Treatment is a multifunctional fuel additive which uses a unique enzyme technology that allows all engines to start easily and run smoothly, even when using ethanol-blended fuel or after sitting idle for months. Star Tron allows fuel to burn more completely, which results in maximum performance, fuel efficiency and reliable operation. Star Tron will stabilise fuel for up to two years, preventing the formation of gums and other solids that clog carburetors and fuel injectors. Star Tron helps prevent phase separation by dispersing water throughout fuel as submicron-sized droplets that can be safely eliminated while the engine operates. Star Tron Small Engine formula is ideal for use in all gas engines including; boats, cars, trucks, motorcycles, small equipment as well as engines that use pre-mix fuel.Makes all engines start easily, run smoothly; improves performanceRemoves & prevents gum, carbon and varnishWorks in all engines and in all fuelHelps prevent phase separation by dispersing water throughout fuel as submicron-sized droplets that are safely eliminated while the engine operates
