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.

What is a car air conditioning compressor?
The car air conditioning compressor is the heart of the vehicle's climate system, ensuring the flow of cooled air into the cabin. Its main function is to compress the refrigerant and direct it to the condenser, where it cools and turns into a liquid, allowing chilled air to reach the interior.

What is a Car Air Conditioning System?
The car air conditioning system (Car Air Conditioner) is a system that ensures a comfortable temperature inside the vehicle by removing excess heat and humidity. The air conditioning system operates in a closed circuit, using a special refrigerant (Freon) to maintain the cooling cycle.
How Does a Car Air Conditioning System Work?
The air conditioning system works on the principle of heat transfer, where heat is removed from the vehicle's interior and released into the external environment. The main stages of this process are:
Compression of the refrigerant: The air conditioning compressor increases the pressure and temperature of the refrigerant.
Heat dissipation: The condenser removes the heat from the high-pressure gas, converting it into a liquid.
Expansion of the refrigerant: The expansion valve lowers the pressure of the liquid refrigerant, cooling it.
Heat absorption: The evaporator absorbs heat from the cabin, turning the liquid refrigerant back into gas.
The cycle continues: The compressor pulls back the heat-absorbed refrigerant, and the process repeats.

Rapid wear of wiper blades is a problem that can occur even on brand new cars. If new wiper blades start to streak, leave spots on the glass or start to skip after just a few weeks or months, the fault is usually not with the product itself. Most often, the cause is invisible dirt accumulated on the surface of the windshield or the wipers are working at the wrong angle.
Below is an overview of the main causes and solutions.

types of car climate oils
1. pag oils (polyalkylene glycol)
The most common type of car air conditioning oil for R134a and R1234yf refrigerants.
Why is pag oil used?
mixes very well with refrigerant
ensures smooth operation of the compressor
suitable for most modern vehicles
The main viscosity classes of pag oils:
page 46 – for smaller compressors, new cars
pag 100 – for standard compressors
pag 150 – for larger systems (trucks, buses)
pros:
optimal compatibility with R134a and R1234yf systems
good lubricity
disadvantages:
hygroscopic (draws moisture from the air)
2. store oils (polyol ester)
The store's oils are also synthetic and are particularly suitable for electric compressors and hybrid cars , where electrical insulation is required.
What is store oil used for?
in r134a and r1234yf systems
in vehicles where the compressor is electrically controlled
in compressors that require special dielectric oil
Common store viscosity grades:
shop 32
shop 46
shop 68
shop 100
3. PAO oils (polyalphaolefin) – versatile and moisture resistant
PAO oils are synthetic oils that are non -hygroscopic, meaning they do not absorb moisture. This makes them useful in difficult conditions.
Why choose pao oil?
suitable for both r134a and r1234yf refrigerants
can be used when unsure of what pag viscosity is needed
better moisture resistance
Common escape classes:
escape 68
escape universal
Universal PAO is popular in repair shops because it is suitable for many systems and is stable.
4. mineral oils (mo / mineral oil)
mainly used in older systems with R12 refrigerant .
Where are mineral oils used?
classic cars
old air conditioning systems that operate with R12 or its substitutes
