Purpose and Specifications

LIQUI MOLY Diesel Particulate Filter Protector is a premium fuel additive designed to keep your diesel particulate filter (DPF) clean and functioning properly. This 250 ml can treats 50-75 liters of diesel fuel, ensuring optimum combustion that cuts soot formation right at the source.

Key practical benefits:

• Reduces soot buildup to prevent DPF clogging and extend filter life
• Lowers the burn-off temperature of soot by over 100°C, making regeneration easier even on short trips
• Improves engine performance and cuts emissions for smoother driving
• Perfect for city driving or vehicles doing under 2,000 km between services

Add one can every 2,000 km just before refueling. DPF normally needs over 550°C to self-clean, but this helper makes it work at lower temps your engine can reach more often.

When to Use / Replace?

Use every 2,000 km or monthly for short-trip drivers to avoid DPF warnings and costly replacements, which can hit 100,000-200,000 km without care. Ideal if your dashboard shows DPF issues or you drive stop-and-go. Shelf life is 3-5 years unopened; store cool and dry.

FAQ:

Can I use this in all diesel cars? Yes, safe for all diesel engines with DPF, especially short-distance vehicles.

How often should I add it? Every 2,000 km before filling up, for up to 75 liters of fuel per can.

Will it fix a clogged DPF? It prevents and aids regeneration; for heavy clogs, use a dedicated cleaner first.
