Types of car air conditioning oil and how to add oil

As a car owner, you need to regularly change the air conditioning compressor oil to keep your car air conditioning system in good condition and to cool the interior temperature. An AC system can work well and last a long time on a car, of course it needs maintenance and oil changes regularly so that the components working in it do not wear out or get damaged.

It is not uncommon for car owners to be unaware of the importance of air conditioning oil. Usually, car owners only know about engine oil and brake oil, but they don't know much about other oils.

In fact, if you understand several important components of your car, you can definitely understand how to take care of your car so that it lasts longer and is always in top condition. The following is an overview of air conditioner compressor oils, starting with its type, its replacement.

Types of car air conditioning compressor oil
There are several types of oil commonly used for an air conditioner. There are several types of oil to choose from for your favorite car.
The following types of air conditioner compressor oil are available:

PAG (polyalkylene glycol) oil
PAG oil is one of the most common types of oil used in car air conditioning systems. This type of oil is a synthetic oil resistant to high temperatures and with good lubricating properties.

PAO (polyalphaolefin) oil
PAO oil is another type of synthetic oil that is often used. This type is resistant to high temperatures and has good stability in various conditions.

Mineral oil
Mineral oil is a type of mineral oil made from mineral materials. Although mineral oil is cheaper, it is less resistant to high temperatures.

How to check the oil in the car air conditioning compressor
You can use the method below to check if your car's air conditioning compressor oil is still suitable or not.

1. Use the appropriate device
2. Visit the service

If you do not have time to check it yourself, it is recommended to take the car to an official repair shop for inspection.

Signs that your car's air conditioning compressor is running out of oil

You can easily find out whether your car's air conditioning compressor still has a lot of oil or is almost out of oil by examining the following features:

1. If the air conditioner compressor runs out of oil, the air conditioner compressor may be unstable, the air conditioner performance will be greatly reduced when cooling.
2. the friction between the compressor components increases, which reduces the performance of the air conditioner compressor. This usually indicates that the compressor is running out of oil.
3. Due to excessive friction between the components of the air conditioner compressor, the air conditioner compressor will break, causing a noisy and harsh sound.
4. When the air conditioner is on, the power of the car will decrease. This is because when the A/C compressor is on, the A/C compressor needs more power to maintain inter-component performance. Therefore, as the amount of oil in the compressor decreases, the A/C compressor will naturally require more power to maintain inter-component performance.


How to change the air conditioning compressor oil in a car?
There are several steps you can take when changing your AC compressor oil. To change the AC compressor oil, do the following.

1. Turn off the air conditioner
Before filling your car's A/C compressor with oil, make sure your AC system is off. Turn off the AC and let the vehicle run for a few minutes. This reduces system pressure, allowing you to work safely and without accidents.

2. Locate the A/C compressor
The next step is to locate the AC compressor in your car. It is usually located near the motor, drive belt or AC capacitor.

3. Locate the oil fill point
After locating the A/C compressor, check the parts and look for the oil filler. Piston type compressors usually have a cover that indicates where the oil is filled. Carefully remove the cap to access the oil fill point.

4. Clean the area around the charging point
Before starting to fill the system with oil, clean the area around the fill point with a clean cloth to remove any dust, dirt or other oil-contaminated residue. This reduces the risk of contamination when oil enters the system.

5. Start filling the oil
It's time to pour oil into the air conditioning compressor. Connect a suitable oil filling device to the pre-determined filling point. Make sure that the charging device and the charging point are securely and tightly connected.

6. Slowly add the recommended A/C compressor compressor oil to the system while filling. To ensure that you do not add more oil than recommended, pay attention to the oil level indicator on the filler tool. Filling with more oil can interfere with the operation of the air conditioning compressor.

7. Replace the cover cap
After filling the oil, make sure the cover cap is tightly fitted. This prevents oil leakage and reduces contamination.

8. Check the performance of the air conditioning compressor
After filling the air conditioner compressor with oil, check the performance of your air conditioner. Check if there are any strange symptoms or sounds and if the air conditioner is producing cool air properly.

After reading the explanation above, you now definitely know the importance of air conditioning compressor oil in keeping your car in top condition. Be sure to take care of your car regularly and pay attention to the above symptoms so that it will be easy to deal with the condition of the car in the future.
