Purpose and Specifications

LIQUI MOLY Pro-Line Engine Flush (2427) is a powerful 500 ml can additive that cleans your engine from the inside before an oil change. It removes stubborn deposits from lubrication holes, oil screens, and piston rings, reducing engine noise and cutting oil consumption for smoother, quieter operation.

• Key Benefits: Improves compression for better power, boosts reliability, and lets fresh oil perform at its best right away.
• Practical Use: Add one full 500 ml can to 3-5 liters of warm engine oil, idle for 10-15 minutes, then drain and replace with new oil and filter.
• Safe For: Turbochargers, catalytic converters, diesel particulate filters, and common seals. Works in operating temps from cold starts to high heat up to 100°C+.
• Shelf Life: Up to 5 years unopened in cool, dry storage.

When to Use / Replace?

Use every oil change, especially after 10,000-16,000 km or 12 months if you notice high oil use, noise, or sluggish performance. Ideal for older engines or those with dirty oil – prevents costly repairs by restoring piston ring seal and oil flow.

Replacement Tip: Flush at each oil change interval (every 10,000 km or 12 months) to maintain peak engine health without double oil changes.
