Purpose and Specifications

Liqui Moly MoS2 Leichtlauf 10W-40 5L is a semi-synthetic engine oil with molybdenum disulfide (MoS2) that creates a tough lubricating film on metal parts. This cuts wear by up to 50% during starts and heavy loads, protects in stop-and-go traffic, and keeps engines running quieter and longer. The 10W-40 viscosity flows easily at cold starts down to -25°C and stays thick up to 220°C under heat.

Meets ACEA A3/B4 and API SL specs for petrol and diesel engines, turbo or not. Ideal for high-mileage vehicles over 100,000 km. Reduces fuel use and oil burn while keeping the engine clean without harming catalytic converters.

When to Use / Replace?

• Use it if: Your car has over 100,000 km, makes lifter noise, or faces extreme conditions like towing or city driving.
• Replace every 10,000-15,000 km or 12 months for everyday cars; extend to 20,000 km in mild use thanks to MoS2 stability.
• Shelf life: 5 years unopened in cool, dry storage.
