Diesel Fuel Conditioner
HD EXPERT™ Diesel Fuel Conditioner helps promote optimal winter performance in heavy duty diesel engines. Our conditioner is formulated to prevent fuel from gelling at extreme low temperatures (down to -40ºC), which can cause filter clogging and vehicle downtime-related costs.
