Cold weather wreaks havoc on diesel vehicles. The paraffin wax found in certain types of diesel crystallizes as the temperature decreases. Wax crystals can block fuel lines and fuel filters creating drivability problems in cold weather.
BG Diesel Fuel Pour Depressant modifies the wax crystal structure of diesel fuel, reducing crystal size and allowing the fuel to flow more readily in cold weather. It does not contribute to corrosion and will not have any negative effects on diesel combustion.
