Reduction in maintenance costs


By eliminating injector deposits and improving combustion, EXCELLIUM Concentrate Diesel enables the engine to maintain its performance. Protection against wear, fuel degradation, water contamination and corrosion contribute to an extended lifetime of engines.​

EXCELLIUM Concentrate Diesel maintains engine power in the long-term thanks to the protection of the injectors against all types of deposits. Its enables restoration of engine power, for example, in only 7 hours (1).

Accumulation of injector deposits not only penalizes fuel efficiency, it might also lead to operation troubles and engine malfunctioning. By keeping the injectors exceptionally clean over time, the occurrence of injector failure and unplanned engine maintenance is reduced.*

Contamination of diesel fuel with water is a significant issue (also favorizing fuel corrosion tendency) and it is vital to separate it quickly and as much as possible from the fuel in case of ingress. EXCELLIUM Concentrate Diesel enables a rapid separation of the fuel from the water in order to eliminate it.


Injection systems are increasingly sensitive, thus enhancing the performance requirements of the filtration systems. By conferring the fuel with improved filtrability, EXCELLIUM Concentrate Diesel protects the diesel filter from premature clogging.
