Fuel additives

Marine fuel additives help protect your engine, improve fuel system performance, and maintain reliable operation in demanding freshwater and saltwater environments. Designed specifically for marine applications, these treatments help prevent fuel degradation, reduce moisture-related issues, clean fuel injectors and carburetors, and protect against corrosion, deposits, and ethanol-related fuel problems. From fuel stabilizers, injector cleaners, ethanol treatments, diesel additives, octane boosters, and fuel conditioners to complete fuel system maintenance solutions, these products help improve starting performance, fuel efficiency, throttle response, and long-term engine reliability. Marine fuel additives are especially beneficial during seasonal storage, extended periods between trips, or when dealing with the challenges of modern fuel blends.
