STA-BIL 360 Marine Ethanol Fuel Treatment

For riders who run a boat or jet ski too. Ethanol fuel pulls in moisture, and on the water that means rust and corrosion in the fuel system. STA-BIL 360 Marine coats the metal parts of the fuel system and combustion chamber, and the coating keeps protecting them when the engine isn’t running. STA-BIL markets it mainly for boats and watercraft, and its maker says it works in gasoline engines generally.
