This treatment removes carbon buildup, gum, and varnish from fuel injectors, carburetors, and intake valves, ensuring smooth and consistent combustion. Its protective ingredients help prevent rust, oxidation, and ethanol corrosion, making it ideal for use in boats, outboards, and other marine engines exposed to moisture and storage conditions. Perfect for both 2-stroke and 4-stroke gasoline engines, this marine additive stabilizes fuel during long-term storage, improves throttle response, and supports easier starts after inactivity. Each 20 oz (591 ml) bottle treats multiple fuel tanks, making it a practical choice for both regular operation and seasonal maintenance. Use regularly to preserve engine performance, reduce deposits, and extend equipment life in all marine applications.
