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 low-friction formula reduces internal engine resistance, which means your engine works more efficiently and uses less fuel.

The oil meets strict international standards including ACEA A3/B4, API SP, and manufacturer approvals for Mercedes-Benz (MB 229.3), Volkswagen (VW 501.01, VW 505.00), Renault (RN 0700/RN 0710), Fiat (9.55535-D2, 9.55535-G2), and PSA vehicles (B71 2300). It flows instantly at cold temperatures (down to -39°C) while maintaining protective strength at high engine temperatures up to 100°C.

Key Benefits:

• Reduces fuel consumption and emissions through low-friction technology
• Keeps engines clean by suspending dirt and preventing black sludge buildup
• Protects seals and prevents leaks, especially important for high-mileage vehicles
• Tested safe for turbochargers and catalytic converters
• Excellent wear protection for engine components
• Works year-round in all weather conditions

When to Use / Replace?

Ideal for vehicles with over 100,000 km on the odometer. This oil is specifically formulated to regenerate and maintain engine seals that may have hardened or shrunk over time, making it perfect for older or high-mileage engines.

Follow your vehicle manufacturer's recommended oil change intervals, typically every 10,000–15,000 km or annually, whichever comes first. Always check your owner's manual for your specific vehicle's requirements. The 5-liter container provides enough oil for most standard oil changes with room for top-ups between services.

This oil remains stable for extended storage periods thanks to its optimized aging resistance, so it won't degrade if kept in a cool, dry place.

Frequently Asked Questions

Q: Can I use this oil in my turbocharged diesel engine?
A: Yes. Super Leichtlauf 10W-40 is tested and approved for both gasoline and diesel engines with turbochargers and catalytic converters.

Q: Is this oil compatible with my current engine oil?
A: Yes. This oil is miscible with all commercially available motor oils, so you can safely mix it if needed during top-ups.

Q: My car has 120,000 km—is this the right oil?
A: Absolutely. This oil is especially recommended for vehicles over 100,000 km because it regenerates engine seals and reduces oil consumption in older engines.
