MOTUL DIESEL SYSTEM CLEAN + is a cleaner additive design to be used in all types of Diesel injection systems, with indirect or direct injection, naturally aspirated or turbocharged, with or without DPF (Diesel Particulate Filter) and with or without SCR (Selective Catalyst Reduction) systems.
MOTUL DIESEL SYSTEM CLEAN + effectively cleans dirtying and clogging which appear in the whole Diesel fuel injection system:
- 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.

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.
