LIQUI MOLY Diesel Lubricity Additive (20454) – Fuel System Protection & Performance

Purpose and Specifications

The LIQUI MOLY Diesel Lubricity Additive (Product Code P000031) is a specialized fuel treatment designed to protect your diesel engine's fuel injection system from wear and corrosion. This 150 ml bottle treats up to 80 liters of diesel fuel, making it economical for regular maintenance.

Key Benefits:

• Reduces friction and wear in fuel pumps and injectors, extending their service life significantly
• Corrosion protection guards against rust in fuel lines and system components
• Excellent aging protection keeps diesel fuel stable over time, especially important for vehicles used seasonally or stored for extended periods
• Simple to use – just pour into your fuel tank; it mixes automatically with no special procedures needed
• Catalytic converter safe – tested and approved for use with modern emission control systems

When to Use / Replace?

Add this additive to your diesel fuel at every fill-up or at minimum every 2,000 km (1,200 miles) of driving. One 150 ml bottle is sufficient for approximately 80 liters of fuel. For vehicles driven regularly in harsh conditions, cold climates, or those using low-quality diesel, more frequent application provides better protection. Diesel stored for winter or long-term use benefits greatly from this additive's aging protection properties.

Operating Conditions:

• Suitable for all diesel engines with or without turbochargers
• Works effectively in temperatures from -27°C to standard operating ranges
• Compatible with all commercially available diesel fuel types
• Safe for modern emission systems including catalytic converters and particulate filters (DPF)
