Cleaning the Fuel Injection System

Model: Mercedes Classe E W210 - Years 1995-2002
Part: Engine

There are many products available for cleaning and lubricating the injection system; the one shown in the video is certainly one of the best on the market, and its formulation allows it to remove deposits not only from the injectors but also from the pistons and combustion chambers, eliminating some engine performance issues such as the so-called 'knocking' under partial load, ensuring a smoother idle and operation of the engine. Cleaner injectors provide optimal engine performance, and cleaning the entire fuel system increases efficiency. Additionally, this additive has a corrosion-inhibiting function, ensuring good combustion, reducing fuel consumption, and increasing reliability. You can perform a preventive application by adding it to the diesel tank during inspection intervals or, in case of problems, carry out a more intensive intervention: disconnect the fuel intake hose and insert the hose directly into the additive container, start the engine, and let it run at various RPMs.
