Amsoil’s Diesel Concentrate Plus Cold Flow Improver combines the detergency of the concentrate and the anti-gelling properties of the improver in one package, eliminating the need to carry two diesel additives.
DFC helps keep injectors, rings and piston crowns lubricated and free of soot. During cold weather, DFC reduces the cold filter plugging point by as much as 34 degrees Fahrenheit in ultra-low-sulfur diesel fuel and reduces the pour-point temperature of treated diesel fuel, providing better fuel delivery to the injectors.
DFC is formulated with a jet-fuel-type de-icer that controls ice formation in the fuel system. While formulated specifically for ULSD fuel, this product also performs well with non-ULSD fuels, including biodiesel up to B20. One 16-ounce bottle treats 40 gallons.
