All diesel fuels carry small amounts of water that are removed from the fuel by the fuel filtration system. When the ambient (outside) temperature drops below 32癋. (0癈.), the water will freeze on the face of the fuel-filter and reduce or stop the flow of fuel to the fuel injection pump and injectors. Power Service Diesel 9 can be used as a preventive measure by dispersing the water present in diesel fuel to prevent fuel-filter icing or to de-ice a frozen fuel filtration system.
