What type of oil is used wih r-410a?

R-410A refrigerant is typically used with polyol ester (POE) oils. POE oils are synthetic and are preferred because they are compatible with the high-pressure environment of R-410A systems, as well as providing suitable lubrication for the compressor. It’s important to avoid using mineral oils with R-410A, as they are not compatible and can lead to system failures.
