Liqui Moly Molygen New Generation SAE 0W-20 Fully Synthetic - Smooth

In this review of Liqui Moly Molygen New Generation SAE 0W-20 the bottom line is simple: this fully synthetic engine oil is for drivers who want reliable cold-start protection, reduced friction and measured fuel economy gains. The formula's MFC molecular friction control and unique additive technology deliver instant lubrication after cold starts and steady oil pressure under all operating conditions, which is the single biggest reason to choose it for modern engines, especially turbocharged cars with catalytic converters.

Key Features

• Instant lubrication after cold start: The 0W-20 viscosity flows quickly on start-up to reduce wear during the most vulnerable moments for the engine.
• Optimum oil pressure: Designed to maintain stable oil pressure under a wide range of temperatures and driving loads for consistent protection.
• MFC additive technology: Molecular Friction Control reduces frictional losses and helps improve fuel consumption compared with conventional oils.
• Compatibility with emissions systems: Formulated to be ideal for turbocharged engines and catalytic converters without harming aftertreatment performance.
• Mixable with other oils: Miscible with commercially available motor oils for easier top-ups and service transitions.

Who It's For

Liqui Moly Molygen 0W-20 is best suited to owners of modern gasoline engines that specify 0W-20 or similar low-viscosity oils, including cars with turbochargers and catalytic converters. Drivers who want smoother cold starts, quieter operation and a potential small improvement in highway mileage will see the most benefit.

Those running older engines with higher oil consumption or vehicles that require thicker grades should look for a different viscosity. Also, if a manufacturer specifically mandates a different specification beyond viscosity, follow the vehicle maker's recommendation.

Pros & Cons

Pros

• Immediate cold-start lubrication helps reduce engine wear on startup.
• Performs well with turbocharged engines and catalytic converters, protecting emissions systems.
• Customers report improved smoothness, reduced engine noise and slight fuel economy gains.

Cons

• Premium fully synthetic oil can cost more than standard oils, though many users find it good value.
• Not a replacement for following specific OEM oil specifications if your vehicle requires a different formula.
