Prevents the formation of paraffin crystals and filter clogging. Improves fuel flow at sub-zero temperatures and lowers the pour point of the fuel to -39°C. The additives contained in the product lubricate the fuel pump. Clean the injectors and protect the entire system from corrosion. Increases the cetane number of diesel fuel. Which ensures trouble-free starting even in extreme conditions. Shake before use and use preventively before the formation of paraffin crystals. Before refueling, pour DFA-39 into the tank and then fill the tank to the brim (100 ml of additive per 120 l of fuel). When using summer diesel fuel, it is recommended to use double the amount (100 ml of additive per 60 l of fuel). Overdosing the product is safe and will not damage the system. 1 l of additive is enough for 1200 l of fuel.
