A/C Compressor Oil- Using the Correct Oil Matters!

It has been seen that most AC compressor problems arise not due to faulty products but due to poor knowledge of AC system operation and repair. One main reason that contributes to AC compressor issues is the oil used.

Choosing the right oil is vital for efficient performance

The main function of oil in an auto’s AC system is lubrication. It also lets the heat emit out from the compressor. However, choosing the right oil is necessary for it to function effectively. What happens if the oil is not chosen correctly?

Following are some pitfalls concerning AC compressor oil that need to be considered. 

Wrong Quality

Insufficient lubrication causes damage or failure of the compressor system. Diluted oil leads to a fall in the lubricant base layer resulting in the rubbing of the piston against the surface bearing the cylinder.

If the oil viscosity is too thick, it cannot squeeze between the piston and the cylinder resulting in greater frictional resistance. That, in turn, jacks up the temperature of the compressor leading to subsequent seizure.

Wrong Quantity

The quantity of oil used is another vital aspect that has to be paid attention to. If the quantity falls short, it fails to offer the required lubrication to the compressor, causing the component temperature to increase. It scorches the oil on the compressor’s suction side. If the quantity is in excess, the piston crank system load is increased.

Clear of Impurities

The compressor oil has to be cleared of all solid impurities through the filter dryer. The oil is also freed of moisture, if any, by the filter dryer. During the yearly maintenance of the AC system, it is necessary to replace some quantity of the oil with an equal measure of fresh oil.

On a Summarising Note

If you want to increase the life of your AC compressor, it is essential to use AC compressor oil of the right quantity and viscosity. It is best to refer your vehicle to a reputed AC specialist who deals in spare parts of the highest quality and sourced from reputed suppliers.
