True Brand^® Marine Fuel Treatment and Stabilizer is specially formulated for engines used in marine environments. Safe for use in all inboard and outboard motors, personal watercraft, and other marine sport engines. It fights the problems caused by ethanol fuel through advanced water removal technology. Its highly concentrated blend of detergents and cleaners removes deposits from fuel system components such as injectors, intake valves, and combustion chambers, for easier starting, less stalling, smoother idling, and better throttle response.

Pour 1 ounce (30 ml) of True Brand Marine directly into fuel tank for every 5 gallons (19 L) of fuel to be treated. One bottle treats up to 50 gallons of fuel.
