As the temperature drops, the wax naturally found in diesel fuel begins to crystallize. The point at which wax crystals form is known as the cloud point. These wax crystals eventually clog the fuel filter and starve the engine of fuel, preventing it from starting. While low-quality fuels may form wax crystals in temperatures as warm as 40ºF (4ºC), most fuels have a cloud point near 32ºF (0ºC). The point at which the crystals clog the fuel filter is known as the cold filter-plugging point (CFPP).

2009 Ford F-450 Super Duty: Lariat. OmahaAMSOIL Diesel Cold Flow lowers the CFPP by up to 20ºF (15ºC) in ultra-low-sulfur diesel fuel (ULSD). It uses a jet-fuel-type deicer that disperses water to control ice formation throughout the fuel system. AMSOIL Diesel Cold Flow inhibits wax crystal formation, allowing fuel to flow to the engine more easily and improving diesel engine reliability in cold temperatures. If gelling has already occurred, AMSOIL Diesel Recovery quickly liquefies gelled diesel fuel and thaws frozen fuel filters in engines that haven’t been treated with Diesel Cold Flow.
