Purpose and Specifications

LIQUI MOLY Super Leichtlauf 10W-40 is a synthetic engine oil engineered for modern gasoline and diesel engines, including turbocharged models. This premium oil delivers low-friction performance that reduces internal engine resistance, helping your engine run smoother while improving fuel efficiency.

The oil meets strict international standards including ACEA A3/B4, API SP, and manufacturer approvals for Mercedes-Benz (MB 229.3, MB 229.1), Volkswagen (VW 501.01, VW 505.00), Renault (RN 0700, RN 0710), Fiat (9.55535-D2, 9.55535-G2), and PSA (B71 2300). It has been tested and approved for use with turbochargers and catalytic converters.

Key Benefits

• Outstanding engine cleanliness: Prevents black sludge buildup and keeps internal components clean
• Instant lubrication at cold start: Flows quickly even at low temperatures (pour point -39°C), protecting your engine immediately
• Seal regeneration: Keeps shaft seals and valve stem seals flexible, reducing oil leaks and consumption
• Excellent wear protection: Guards against engine wear across both high and low temperature ranges
• Fuel savings: Low-friction formula reduces energy loss, lowering fuel consumption and emissions
• Long-term stability: Resists aging and shear forces, maintaining protection throughout the oil change interval

When to Use / Replace?

Ideal for vehicles with over 100,000 km on the odometer. This oil is specifically formulated to address the needs of high-mileage engines, where seal flexibility and engine cleanliness become increasingly important.

Oil change intervals: Follow your vehicle manufacturer's recommended service schedule, typically every 10,000 to 15,000 km or annually, whichever comes first. Check your owner's manual for exact intervals, as modern engines with extended maintenance may allow longer periods between changes.

Operating temperature range: This all-season oil performs reliably from -39°C (cold winter starts) to 100°C+ (highway driving and heavy loads). Flash point is 228°C, ensuring safety during normal operation.

Storage: Store in a cool, dry place. Unopened containers maintain quality for several years when stored properly away from direct sunlight and extreme temperatures.

Compatibility

This oil is miscible with all commercially available motor oils, making it safe to top up with other brands between service intervals if needed. However, for best results, use the same oil for complete changes.
