* To maintain proper lubrication: The compressor oil lubricates the moving parts of the compressor, reducing friction and wear. Over time, the oil can become contaminated with metal shavings, dirt, and other debris, which can reduce its effectiveness and lead to premature compressor failure.
* To prevent leaks: The compressor oil also helps to seal the compressor against leaks. If the oil level is too low, the compressor can start to leak, which can lead to a loss of refrigerant and a decrease in cooling performance.
* To protect the compressor from damage: The compressor oil helps to protect the compressor from damage caused by overheating. If the oil level is too low, the compressor can overheat and fail.
It is important to change the car AC compressor oil according to the manufacturer's recommendations. The frequency of oil changes will vary depending on the type of compressor and the operating conditions. However, most manufacturers recommend changing the oil every 2-3 years or every 30,000-50,000 miles.
