Purpose and Specifications

LIQUI MOLY Diesel Flow Fit K 5132 is a premium diesel fuel additive in a 5-liter container designed to keep your diesel flowing smoothly in cold weather. It improves fuel flow and filtration, preventing paraffin wax crystals from clogging filters and lines, so your engine starts reliably even at temperatures down to -31°C, depending on fuel quality.

This self-mixing additive treats up to 5,000 liters of diesel at a 1:1000 ratio, making it perfect for vehicles, trucks, construction equipment, and stationary engines including Euro 6 models. Add it before refueling for easy use, and it secures winter operation without affecting turbochargers or emissions systems.

• Keeps diesel flowing in extreme cold for dependable starts
• Enhances filter performance to avoid blockages
• Simple to dose and mixes automatically
• Suitable for all diesel fuels per DIN EN 590 standards

When to Use / Replace?

Use before winter or in cold climates when temperatures drop near your diesel's cloud point. For best results, add when fuel is about 5°C above the cloud point to prevent wax buildup—treat every 10,000 km or at each seasonal change. Shelf life is 5 years if stored above 0°C in a frost-free area; bring to room temperature if frozen before use.

Do not add after crystals have formed, as it won't dissolve them. Reapply with every major refuel in winter for ongoing protection.
