Purpose and Specifications

Liqui Moly 2428 Pro-Line Engine Flush is a powerful 5-liter cleaner that safely removes engine deposits, sludge, and lacquer from oil holes, bearings, and piston rings before your oil change. It restores proper oil flow for better lubrication, reduces noise and oil consumption, and lets fresh oil perform at full strength right away. Perfect for gasoline and diesel engines with turbochargers, catalytic converters, and DPF filters.

• Volume: 5 liters – ideal for heavy-duty or fleet use with 30-50 liters of oil
• Key Benefits: Optimizes oil pressure, improves cold starts, cuts fuel use, and protects seals without damage
• Safe Operating Temps: Works at normal engine temps (80-100°C); idle 10-15 minutes after adding

When to Use / Replace?

Use before every major oil change (every 10,000-20,000 km or 12 months) if your engine runs noisy, smokes, or guzzles oil. Add to warm oil, idle briefly, then drain – no need for disassembly. Not for motorbikes with wet clutches. Repeat every oil service for engines over 100,000 km to maintain peak performance.
