Purpose and Specifications

LIQUI MOLY Engine Flush 300ml is a highly effective cleaning fluid designed to clear troublesome deposits from the interior of gasoline and diesel engines. This 300ml bottle treats up to 6 liters of motor oil, safely suspending both oil-soluble and oil-insoluble residues for easy removal during your next oil change.

Add it directly to warm engine oil at operating temperature, idle for about 10 minutes, then drain the oil and replace the filter. It's gentle on seals, turbochargers, catalytic converters, and particulate filters, ensuring optimal engine performance without disassembly.

• Cleans engine internals fast for smoother operation and reduced wear
• Compatible with all commercial motor oils
• Improves idle quality - users report dropping from 750rpm to 500rpm after use
• Boosts fresh oil effectiveness by removing sludge buildup

Practical benefits include quieter running, better fuel efficiency from cleaner combustion, and longer engine life. Use every 30,000 to 50,000 km or during oil changes if you notice rough idling or high oil consumption.

When to Use / Replace?

Use LIQUI MOLY Engine Flush before every major oil change, especially in high-mileage vehicles over 100,000 km or those with irregular maintenance history. It's ideal if your engine sounds noisy on startup, idles roughly, or consumes more fuel than usual. Perform at operating temps around 80-90°C for best results.

Shelf life is typically 3-5 years when stored in a cool, dry place. One 300ml bottle per oil change; no need to replace more frequently unless heavy sludge is present.
