Abstract
A lubricating composition has been found which has particular utility in gas compressors. The composition comprises a polyalphaolefin base oil, an ester oil solubilizer, antioxidants and metal passivators. The composition replaces a mineral oil formulation and demonstrates comparable thermal and oxidative stability in the absence of sulfur, phosphorous and metal additives.
