The purity of the fuel simultaneously means instant savings, better engine performance and reduced deposits that in the long run result in significant wear and maintenance costs, respectively. In diesel engines, especially modern direct injection common rail engines, the injection system, the pumps and the entire fuel circuit are extremely sensitive to the presence of particles and water.
Another important factor that can affect engine performance and cause harmful deposits in the injection system (injectors), is the formation of deposits from combustion and crystallization of the fuel (paraffin formation) that may occur during the winter months because of low temperatures.
