Ester oil is often called “retrofit oil” because it mixes with both R-12 and R-134a. These numbers refer to the viscosity of the oil, similar to 10W30 oil. Esterification – the reverse of hydrolysis. Like PAG oil, PVE oil does not undergo hydrolysis in the presence of water. WAECO PAG ISO 46 - WAECO offers quality compressor oil to provide the best possible repair and maintenance results for car A/C systems. In other words, socketing a Timeless Jewel and anointing a passive node will grant the new, transformed modifiers. So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil. PAG is actually an acronym for Polyalkylene Glycol, and it is a synthetic oil used in A/C systems to lubricate the compressor. 1. The most hygroscopic refrigerant oils in descending order are: PAGs, PVEs, POEs, ABs, and mineral oils. The other approach to retrofit is the "quick and cheap" one. Because mineral oil and PAG oil cannot be mixed, another A/C compressor oil was needed to bridge the gap for system conversions. The speed at which hydrolysis occurs is dependent on temperature and the acid content (acids can act as a catalyst). The only way to remove the moisture is through the use of oversize filter-driers in the system.
