Product Features

  • REMOVES WATER : Fuel Ox Marine is a demulsifier for the water that is in fuel. It will separate the water suspended in gas or diesel and filter out through your boat's or watercraft's racors, separators, or filters. It prevents water from passing through engine and significantly slows the process of phase separation.
  • 1OZ TREATS UP TO 80 GALLONS OF GAS OR DIESEL : Fuel Ox Marine has a highly concentrated formula that treats both gas or diesel for a small and convenient inventory.
  • PROTECTS AGAINST ETHANOL : Fuel Ox Marine coats fuel tank and system to prevent corrosion from ethanol found in gasoline.
  • INCREASES FUEL ECONOMY : Fuel Ox Marine contains a patented combustion catalyst that provides a more complete combustion. This allows for more productive burn of fuel.
