How Much Refrigerant Oil Should Be Added to a Car Air Conditioner?

[LawsonFitz]

Car air conditioner refrigerant oil should be added in an amount of approximately 30ml to 70ml. The correct method for adding refrigerant oil is as follows: 1. Open the car hood and locate the high and low-pressure pipes of the air conditioner—the larger one is the low-pressure pipe, and the smaller one is the high-pressure pipe. 2. Check if the charging valve is qualified, and avoid using inferior quality charging valves. 3. Connect the high and low-pressure pipes of the air conditioner to the red and blue pipes on the air conditioner pressure gauge device, and connect the yellow pipe on the device to a vacuum machine for vacuuming. 4. Turn off the vacuum machine and remove the high-pressure pipe. 5. Shake the bottle up and down before use to ensure the contents are evenly mixed, and add the appropriate amount from the compressor service port as needed.
