PAG (Polyalkylene Glycol) oil is primarily used in automotive air conditioning systems and is hygroscopic, meaning it absorbs moisture, which can lead to issues in certain systems. POE (Polyol Ester) oil, on the other hand, is commonly used in refrigeration systems with HFC refrigerants and offers better moisture tolerance and chemical stability, making it suitable for a wider range of applications.
