Refrigerant Oil: Service and Repair

Filling And Adjusting Compressor Oil


The A/C system is filled with 150 ml of compressor oil for the A/C pump (petroleum) and 295 ml for A/C pump (diesel). A certain amount of compressor oil is always lost in when draining refrigerant and when changing components. This amount must be topped up again so that the system operation will not be adversely affected.

Filling of compressor oil should be done on the compressor high-pressure side. The compressor oil is supplied in tubes of 20 ml.
The tables below indicate how much compressor oil that is lost in conjunction with various types of service work on the A/C system.
