Purpose and Specifications

LIQUI MOLY 5148 Diesel Particulate Filter Protector is a premium fuel additive in a 250 ml can designed to safeguard your diesel particulate filter (DPF) from soot buildup and clogging. It ensures better fuel combustion, cuts soot emissions, and extends DPF life, especially for short trips and city driving where exhaust temps often stay below 600°C needed for natural cleaning. Add every 2,000 km before refueling; one can treats 50-70 liters of diesel for smooth engine performance, lower fuel use, and fewer breakdowns.

When to Use / Replace?

Use regularly on vehicles doing short drives under 10 km or city stops to prevent DPF failure, which can hit as early as 16,000 km without protection but lasts over 100,000 km with it. Ideal if your warning light flashes or power drops; shelf life is 4 years unopened. No need to replace the additive itself, just dose every 2,000 km or 2 months for ongoing protection.

• How does it help short trips? Reduces soot so DPF regenerates easier even without high temps, keeping your engine quiet and efficient.
• Is it safe for the environment? Lowers emissions and protects waterways when used as directed.
