A clean fuel system is a necessary condition for an effective engine running. MOTUL DIESEL SYSTEM CLEAN allows to:
  • Clean the pump and the injectors (for a better atomization of Diesel fuel)
  • Prevent the formation of deposits and varnishes on inlet valves and in combustion chambers
  • Disperse condensation water in order to avoid any fuel system oxidation

A regular use will provide:

  • Easier cold starting
  • Fuel savings
  • Optimum engine performances
  • Increased lifetime of fuel system and catalytic converter
  • A reduction of exhaust pollutants emissions (smoke, particles…)

Technical Information:

Directly pour one can of DIESEL SYSTEM CLEAN in the tank before refueling, regularly, depending on the use (shorten intervals in urban use). The fuel system will be then completely cleaned, from the tank to the combustion chamber. A can is sufficient for tanks up to 60 liters. For bigger tanks, the recommended mixing ratio of Diesel System Clean is 0.50% (200:1). Do not exceed the recommended proportion. If necessary, proceed to 2 successive treatments. Curative treatment : use the product pure by plugging on the fuel system with the adaptation kit.
