Refrigerant Oil: Description and Operation

If the refrigerant charge is abruptly lost due to a large refrigerant leak, (hose rupture or collision) approximately 132 ml (4.5 oz) of refrigerant oil will be carried out of the system suspended in the refrigerant. Any failure that caused an abrupt refrigerant discharge will cause this oil loss. Conditions that allow the refrigerant to seep or bleed off over time do not cause this oil loss.

Upon replacement of a component which caused a large refrigerant leak, add 132 ml (4.5 oz) of new PAG compressor oil plus the required amount of oil for the particular component (as outlined previously).

Add the oil directly to the replaced component if possible. If the oil cannot easily be added to the replaced part, add the oil to the liquid line (as outlined previously).
