What Is LIQUI MOLY Leichtlauf HC7 5W-40?

LIQUI MOLY Leichtlauf HC7 5W-40 is a modern, low-friction engine oil developed for year-round use in compatible petrol and diesel engines. Its formulation combines hydrocracked base oils with modern additive technology to provide dependable lubrication, support engine cleanliness and help reduce friction-related energy losses.

The SAE 5W-40 viscosity grade provides a balance of cold-start flow and lubrication at operating temperature for engines designed to use this grade. The oil is intended for compatible engines with multivalve technology and turbocharging, with or without charge-air cooling. It can also be suitable for selected CNG- and LPG-powered passenger vehicles.
