Diesel additive to be added directly in the fuel tank. This product works as a remover for contamination in the fuel system, cleaning from the tank to the combustion chamber. It can be used in all diesel engines, and was particularly developed for high pressure direct injection diesel engines with common rail technology or pump injectors. It is suitable for engines using diesel Particulate Filters (DPF).

MOTUL DIESEL SYSTEM CLEAN effectively cleans dirtying and clogging which appear in the whole Diesel fuel injection system, thus limiting or avoiding:
- injector nozzle fouling
- condensation in the fuel system
- gumming in the injection pump
- dirtying of combustion chambers and inlet valves

MOTUL DIESEL SYSTEM CLEAN provides a perfect lubrication during cleaning phase and prevents removed micro-particles from depositing. Moreover, it prevents from Diesel fuel oxidation and microorganisms formation.
Cleaning the fuel system is essential to ensure optimal combustion, reduce fuel consumption and exhaust emissions, avoid any breakage in the engine, leading to costly repairs.

Recommended to be used when:
- Loss of power/acceleration, rough start
- Check engine light on 
- Grey or black smoke at the exhaust
- Overconsumption of fuel

Usage interval: Every 5.000 - 10.000km.
