Diesel Extreme Injector Cleaner

Injector cleaner

Wynn's Diesel Extreme Injector Cleaner is a diesel fuel additive, which provides a strong one tank clean-up of the diesel fuel system.

  • Complete and rapid cleaning of the entire fuel system in one tank filling.
  • Protection of high pressure injection systems (TDI, HDI, ...).
  • Instantly cleans and protects the injectors, restores and maintains ideal injector spray pattern.
  • Restores engine performance, provides a regular idle and avoids starting problems.
  • Prevents clogging on EGR.
  • Effectively protects and lubricates injectors and pumps.
  • Increases operational reliability and economy.
  • Meets Euro 5/Euro 6 standard.
  • EN 590 compatible.
  • Harmless for all after-treatment systems.


For all diesel engines, including common rail and pump injector engines.
For diesel and bio diesel up to B30.


For an optimal cleaning effect, add one bottle of 500 ml to up to 60 litres of diesel fuel.
In case of heavy fouling of the engine, add one bottle of 500 ml to minimum 30 litres of diesel fuel.
Bottle is also suitable for capless fuel fillers.

Both modern cars and older vehicles have specific requirements, that have a chemical solution to provide the optimal engine performance and driving comfort. Modern fuel systems are highly tuned and therefore more susceptible to the negative effects of chemical reactions in the fuel. These lead to fouling of the fuel system, lack of lubrication, corrosion and other problems. Older vehicles experience problems to obtain the correct air/fuel ratio and combustion efficiency due to accumulation of deposits in the fuel system and wear on the components.
