Purpose and Specifications

LIQUI MOLY MoS2 Low-Friction 15W-40 is a premium all-season motor oil engineered for gasoline and diesel engines, including turbocharged models. This oil contains molybdenum disulfide (MoS2), a solid lubricant that creates a protective film on engine metal surfaces, reducing friction and wear.

Key Benefits:

• Reduces engine wear and extends engine life significantly
• Lowers fuel consumption by 2-5% through friction reduction
• Improves cold-start lubrication—instant protection even in freezing conditions
• Reduces engine noise and vibration for smoother operation
• Outstanding engine cleanliness and deposit control
• Stable viscosity across temperature ranges (winter cold starts to summer heat)
• Safe for catalytic converters and turbochargers

Specifications: ACEA A3/B4, API SL. Suitable for long oil change intervals and extreme operating conditions including towing and high-load driving.

When to Use / Replace?

Oil Change Interval: Follow your vehicle manufacturer's recommended service schedule, typically every 10,000-15,000 km or 6-12 months, whichever comes first. MoS2 protection remains effective for at least 50,000 km of driving.

Operating Temperature Range: This 15W-40 oil performs reliably from -20°C (winter cold starts) to +40°C (normal summer driving). The 15W rating ensures quick flow in cold weather; the 40 rating maintains film strength at highway temperatures.

Shelf Life: Store in a cool, dry place. Unopened containers remain stable for several years when stored properly.

When to Replace: Change oil when your vehicle's service indicator activates or at manufacturer intervals. Dark, dirty oil or low oil level readings indicate replacement is needed.

Frequently Asked Questions

Q: Will MoS2 additive damage my engine or catalytic converter?
A: No. LIQUI MOLY MoS2 Low-Friction 15W-40 is tested and approved safe for catalytic converters and turbochargers. It meets strict emissions standards and will not harm modern engine components.

Q: Can I use this oil in both my gasoline and diesel vehicles?
A: Yes. This oil is formulated for both gasoline and diesel engines, with or without turbocharging. It works equally well in either engine type.

Q: How much fuel savings can I realistically expect?
A: Real-world fuel consumption improvements typically range from 2-5%, depending on driving habits, engine condition, and vehicle type. Smoother engine operation and reduced friction contribute to these savings over time.
