MOTUL® ALL IN ONE ULTRA DIESEL is a complete concentrated multi-action curative fuel additive cleaner for Diesel injection systems used in all types of Diesel engines, indirect or direct injection, naturally aspirated or turbocharged, with or without DPF (Diesel Particulate Filter), with or without SCR (Selective Catalyst Reduction), and using Diesel or Biodiesel fuel.
MOTUL® ALL IN ONE ULTRA DIESEL is a concentrated Diesel additive compatible with Biodiesels B7 (Biodiesel 7%) and B10 (Biodiesel 10%).

MOTUL® ALL IN ONE ULTRA DIESEL effectively cleans deposits and fouling inherent in the operation of Diesel engine fuel systems thanks to its curative multi-action properties thus limiting:

- injector nozzle fouling

- dirtying of combustion chambers and inlet valves

- gumming in the injectors and injection pump

- corrosion in the fuel system

MOTUL® ALL IN ONE ULTRA DIESEL provides a perfect lubrication during cleaning phase and prevents removed micro-particles from depositing.

By eliminating deposits and fouling from valves, injectors and combustion chambers, MOTUL® ALL IN ONE ULTRA DIESEL enables powerful combustion to restore engine performance.

MOTUL® ALL IN ONE ULTRA DIESEL also increases the Cetane number of the fuel, achieving optimal combustion and reducing fuel consumption.

MOTUL® ALL IN ONE ULTRA DIESEL curative multi-action additive is also formulated to aid in the regeneration of the particulate filter, thereby reducing exhaust gas and particulate emissions.

MOTUL® ALL IN ONE ULTRA DIESEL protects Diesel fuel from oxidation and thus prevents the formation of micro-organisms in the fuel circuit.
