FUELSPEC FE-4 is an organic-metallic combustion catalyst, which improves the oxidation of intermediate and high sulfur fuel oils. When FUELSPEC FE-4 is added to the fuel, resulting reduced emissions (soot, smoke and some gases), the efficiency improves and prolonged the life of the equipment.

FUELSPEC FE-4 is blended for use in all marine and land based boiler powered operations, as well as medium and high speed diesel engines.

FUELSPEC FE-4 is completely soluble in all fuels.

Available in UN approved 5 gallon pails and 55 gallon drums.
