Purpose and Specifications

LIQUI MOLY Diesel Leichtlauf 10W-40 1L is a premium engine oil designed for diesel engines, delivering smooth performance and long-lasting protection. Its 10W-40 viscosity flows easily in cold starts down to -25°C and stays thick up to 150°C under heavy loads, reducing wear on critical parts like pistons and turbochargers.

Approved for major specs including ACEA A3/B3, MB 229.1/229.3, VW 505.00, PSA B71 2294, and Renault RN0710, it suits European diesel cars from Mercedes, VW, Peugeot, and Renault. This oil fights soot buildup common in diesels, keeps engines clean, and supports up to 10,000 km or 12 months under normal driving.

When to Use / Replace?

• Normal use (highway driving, mild weather): Change every 7,500-10,000 km or 12 months to maintain peak efficiency.
• Moderate use (towing, city stop-go): Every 5,000-7,500 km or 6 months prevents sludge from idling.
• Severe use (heavy towing, extreme temps, dusty roads): Every 3,000-5,000 km or 3 months protects against rapid breakdown.

Shelf life is 5 years unopened in cool, dry storage. Always check your owner's manual for exact intervals.
