ABSTRACT:
The present invention relates to a lubricating basestock comprising a blend of (A) at least one polyalkylene glycol and (B) at least one alkyl aromatic. Additives, such as antioxidants, corrosion inhibitors, and metal deactivators, can be added to the lubricating basestock. In one embodiment, the lubricating composition is free of naphthol. The blend can also be used in combination with a variety of oils of lubricating viscosity, with or without additives therein. According to the present invention, the lubricating composition exhibits excellent oxidation and thermal stability, demulsibility, and hydrolytic stability. The lubricating composition is particularly useful as a positive displacement compressor lubricant.
