Description
Liqui Moly Systempflege Diesel
A specialized service additive designed to protect and lubricate precision fuel system components in modern diesel engines. Extends the lifespan of high-pressure pumps. Item #5139.
Modern injection systems require the highest level of lubrication, which is often lacking in low-sulfur diesel fuels. Systempflege Diesel fills this gap, protecting the pump and injectors from seizing.
Lubrication Technology
Friction within the fuel system is the leading cause of metal shavings, which can permanently damage injectors and contaminate the entire system.
-
Wear Reduction: Creates a durable lubricating film on high-pressure pump components and injector needles.
-
Corrosion Protection: Effectively neutralizes the negative impact of moisture in the fuel tank and lines.
-
Fuel Stabilization: Prevents diesel oxidation during longer periods of vehicle storage.


Wide Compatibility
Designed for all diesel engines with Common Rail and Unit Injector (Pump-Injector) systems. Fully safe for diesel particulate filters (DPF/FAP) and catalytic converters.
Engine Benefits
Regular use of this additive leads to stable operation and significantly lower engine failure rates.
-
Engine Smoothness: The engine runs quieter and smoother, especially during cold starts.
-
System Cleanliness: Prevents new deposits from forming, maintaining optimal fuel dosing.
-
Cost Savings: Protects against expensive injector regeneration and high-pressure pump replacement.

Application & Dosage
Simple application providing long-term protection for your diesel engine.
-
Dosage: One can (250ml) is sufficient to treat 75 liters of diesel fuel.
-
How to use: Add the contents of the can to the fuel tank. Mixing happens automatically.
-
Frequency: To maintain continuous protection, use every 2,000 km.
Monitor your fuel system
Well-maintained injectors ensure the stable operation of the particulate filter. Support clean combustion by using DPF Control monitors. Our devices allow you to check DPF status in real-time, completing the protection provided by Liqui Moly additives.
