Refrigerant Oil Properties

WARNING: This page is about a different variant/trim than selected.

The most important properties are the high degree of solubility with refrigerant, good lubrication, no acid content and very minimal water content. For these reasons, only certain oils may be used. A list of approved refrigerant oils and capacities can be found in the vehicle-specific Service Information. Refer to BEETLE/BEETLE CONVERTIBLE (5C2/5C8) or BEETLE / BEETLE CONVERTIBLE (5C2 / 5C8) [2019] .

PAG oils, which are appropriate for refrigerant R134a, are highly hygroscopic and do not mix with other oils. Opened containers should therefore be closed again immediately to prevent ingress of moisture. Moisture and acids promote aging of refrigerant oil, causing it to become dark and viscous as well as corrosive towards metals.

NOTE:

Only use oils approved for the A/C compressor in refrigerant circuits with refrigerant R134a. Refer to the vehicle-specific Service Information. Refer to BEETLE/BEETLE CONVERTIBLE (5C2/5C8) or BEETLE / BEETLE CONVERTIBLE (5C2 / 5C8) [2019] .
