Liqui Moly Molygen New Generation 5W-40 Fully Synthetic Engine Oil, 5 L — MFC Friction Control, Turbo & Cat-Safe

LIQUI MOLY Molygen New Generation 5W-40 is a fully synthetic engine oil formulated with MFC (Molecular Friction Control) technology to reduce friction, keep engines clean, and protect under high stress.

This 5-liter pack (SKU: 20232) is a modern synthetic motor oil designed for gasoline engines requiring current industry specifications. Its Molygen additive package creates a thin, low-friction layer that resists deposit formation and improves mechanical efficiency without compromising compatibility with catalytic converters or turbochargers. The oil’s fluorescent green tint signals the MFC formulation and helps you identify the product during service.

How does Molygen New Generation 5W-40 help reduce engine wear?

The MFC (Molecular Friction Control) system forms a robust lubricating film that lowers metal-to-metal contact, decreasing component wear even under heavy load. This protection is maintained across a broad temperature range thanks to the oil’s synthetic base and shear-stable formulation.

• Advanced friction control molecules create a protective boundary layer
• High shear stability preserves viscosity under stress
• Synergistic additives guard bearings, pistons, and camshafts

Will this oil keep my engine clean and perform in extreme temperatures?

Molygen New Generation is engineered for outstanding engine cleanliness and reliable flow from cold starts to high operating temperatures. Its formulation resists sludge and deposit formation while delivering consistent lubrication in both low and high temperatures.

• Excellent cold-start viscosity for faster oil circulation
• Strong high-temperature stability to prevent breakdown
• Detergency and dispersancy additives limit sludge buildup

Is LIQUI MOLY Molygen 5W-40 compatible with modern exhaust aftertreatment and forced-induction systems?

This oil has been tested to be safe for catalytic converters and turbochargers, making it suitable for modern gasoline engines with these systems. Always verify your vehicle manufacturer’s recommended oil specifications before use.

• Formulated to avoid harm to catalytic converters
• Protects turbocharger bearings and shaft under high temperatures
• Meets current gasoline engine performance requirements—check vehicle manual

How does using this 5 L pack benefit maintenance and operating costs?

Buying the 5-liter container reduces the need for multiple small bottles, simplifying oil changes and reducing packaging waste. The product’s fuel-efficiency advantages and wear protection can contribute to smoother operation and potentially lower long-term maintenance expenses.

• Bulk 5 L volume suits most routine service intervals
• Improved fuel economy from reduced frictional losses
• Extended component life through superior protection
