Purpose and Specifications

LIQUI MOLY Molygen New Generation 5W-40 4L is a fully synthetic premium engine oil with MFC (Molecular Friction Control) technology that creates a protective layer on engine parts. This reduces friction for smoother operation, cuts wear by up to 30%, and improves fuel efficiency by up to 15% while keeping your engine exceptionally clean from deposits.

The 5W-40 viscosity flows easily at cold starts down to -30°C for instant lubrication and stays thick at high temps up to 150°C, perfect for turbocharged gasoline and diesel engines. Approved for BMW LL-01, MB 229.5, Porsche A40, VW 502.00/505.00, Fiat 9.55535 specs, and more, it suits European, Asian, and American vehicles with multi-valve or turbo tech.

• Outstanding cleanliness prevents sludge buildup

• Reduces emissions and works with turbos and catalytic converters
• Green fluorescent color helps spot leaks under UV light
