Purpose and Specifications
MOTUL Diesel System Clean is a powerful 300ml fuel additive that thoroughly cleans your entire diesel fuel system, from tank to injectors and combustion chambers. It removes injector nozzle fouling, condensation water, gumming in the injection pump, and dirt on inlet valves and combustion chambers, while providing lubrication to prevent particles from redepositing.
Compatible with all diesel engines, including indirect or direct injection, naturally aspirated or turbocharged, with or without DPF filters or SCR systems. Pour one full can into your tank before refueling, treating up to 60 liters of diesel. For larger tanks, add 300ml per extra 60 liters. Works during normal driving, restoring power, cutting fuel use, reducing smoke emissions, and easing cold starts even in temps down to -10°C.
- Keeps original engine power and smooth performance
- Lowers fuel consumption and exhaust pollutants like soot
- Prevents fuel oxidation and bacterial growth for longer system life
- Shelf life: 5 years unopened, use within 2 years once opened
When to Use / Replace?
Use every 10,000 km or 12 months for maintenance, or immediately if you notice rough idling, power loss, high smoke, or hard cold starts. Repeat treatment twice if heavily clogged. Regular use avoids costly injector or pump repairs and keeps your diesel running strong up to 300,000+ km.
