    摘要: A compressor lubricant composition providing energy savings and exhibiting excellent oxidation stability is provided, as well as a process for preparation of the lubricant composition. The composition comprises: (i) from 68 to 99.999 wt % of an isomerized base oil or blend of isomerized base oils; (ii) 0.001 through 20 wt % of a blend of ashless additives, the ashless additives having a viscosity range at 40° C. of from 50 mm2/s to 60 mm2/s, a density at 20° C. of from 0.95 through 1.05 g/cm3, a flash point of greater than 100° C. (COC), solubility in mineral oil of greater than 5 wt %, sulfur content of from 4.8 wt % through 6.0 wt %, and phosphorus content of from 2.9 through 3.6 wt %; (iii) less than 1.0 wt % of a dithiocarbamate, wherein the Conradson carbon residue is less than or equal to 3.00. The dithiocarbamate is added to the base oil blend as a top treatment.
