Contamination Of Compressor Oil

WARNING: This page is about a different car, the 2005 Kia Spectra5, 2005 Kia Spectra, and 2004 Kia Spectra. However, it is still accessible from the selected car via links, so may be relevant.

Unlike engine oil, no cleaning agent is added to the compressor oil. Even if the compressor runs for a long period of time (approximately one season), the oil never becomes contaminated as long as there is nothing wrong with the compressor or its method of use.

Inspect the extracted oil for any of the following conditions:
The capacity of the oil has increased.
The oil has changed to red.
Foreign substances, metal powder and etc. are present in the oil.

If any of these conditions exists, the compressor oil is contaminated. Whenever contaminated compressor oil is discovered, the receiver/drier must be replaced.
