Liqui Moly Molygen 10W40 1ltr LM9955

Liqui Moly Molygen New Generation 10W-40 is a high-performance, low-friction motor oil designed for year-round use in modern petrol and passenger-car diesel engines, with or without turbochargers.

The combination of unconventional base oils, advanced additive technology and Liqui Moly's special Molygen additive technology provides excellent shear stability while significantly reducing friction and wear inside the engine.

Its formulation provides rapid lubrication after cold starts, outstanding engine cleanliness and excellent high- and low-temperature performance. By reducing frictional losses, Molygen New Generation 10W-40 can contribute to improved fuel efficiency, reduced pollutant emissions and extended engine service life.

The oil's distinctive green fluorescent appearance is characteristic of the Molygen formulation.
