Product description

LIQUI MOLY Diesel Purge 7704 is a concentrated diesel fuel-system cleaner that helps remove deposits from injectors, injection nozzles, and the combustion chamber. It is designed to support cleaner combustion, smoother diesel operation, and dependable fuel-system performance.

Ideal for preventive maintenance or targeted cleaning, this formula helps address diesel knocking at idle, supports quieter running, and provides corrosion protection throughout the fuel system. Suitable for diesel engines with or without turbochargers and compatible with catalytic converters and DPF-equipped vehicles.

How to use

Preventive use: Add Diesel Purge to the diesel fuel system at regular service intervals. When replacing the fuel filter, the filter housing may be filled with Diesel Purge and the remaining product added to the fuel tank.

Professional cleaning use: For a direct fuel-system cleaning procedure, follow the manufacturer’s instructions for disconnecting and reconnecting the fuel lines, run the engine at varying speeds, and stop before the container is empty. Check all connections for leaks afterward.

Important: For diesel engines only. Follow the product label and safety information carefully. Keep away from heat and ignition sources. Professional installation is recommended for direct fuel-line cleaning.
