Liqui Moly Diesel Purge [8380] (500ml)

Liqui Moly Diesel Purge is a high-performance fuel system cleaner designed specifically for diesel engines. It effectively removes carbon deposits on injectors, intake valves, and in the combustion chamber. By boosting cetane number and eliminating engine knocking, it ensures smoother idling, improved fuel efficiency, and enhanced reliability - even under heavy load or poor fuel quality. 

• ✅ Removes stubborn injector and combustion chamber deposits
• ✅ Enhances idling stability and reduces engine noise
• ✅ Boosts cetane value and improves fuel economy
• ✅ Helps prevent soot buildup and extends DPF life
• ✅ Corrosion protection for fuel system components

🛠️ How to Use

1. Add full bottle during fuel filter replacement. Empty rest into fuel tank.
2. Disconnect fuel feed and return hoses from filter. Insert hoses into Diesel Purge container. Start engine and run at varied RPMs without diluting. After cleaning, reconnect fuel system.
3. Run engine under varied throttle for ~30–45 minutes to complete cleaning cycle. Repeat if needed.
4. Do not dilute the product. Use at full strength only for best results.
5. Safe for most diesel engines—avoid use in vehicles with integrated additive DPF systems (e.g., Peugeot)

Ideal for diesel vehicles that suffer from rough idling, reduced fuel economy, or injector issues. Made in Germany and recommended for use every ~2,000 km or during routine service intervals for preventive maintenance.
