Mahle claims that its PAO 68 oil is a practical and cost-effective solution for workshops. Suitable for many types of compressor, the oil is non-hygroscopic, and is compatible with numerous other lubricants and refrigerants.
Reliable lubrication of the air conditioning compressor is thus guaranteed whenever this product is used.
Because the PAO 68 oil doesn’t form permanent bonds, the necessary viscosity of the oils is maintained and changes to their overall viscosity are excluded. In view of these characteristics, PAO 68 oil can be used both when topping up and when changing the system’s entire oil volume.
