    Abstract: A lubricant composition that comprises a hydrocarbon base oil, a polar viscosity improver; and an esterified polyalkylene glycol: R1[O(R2O)n(R3O)m(C═O)R4]p, wherein R1 is a linear alkyl having 1 to 18 carbon atoms, a branched alkyl having 4 to 18 carbon atoms or an aryl with 6 to 30 carbon atoms; R2O is an oxypropylene moiety derived from 1, 2-propylene oxide; R3O is an oxybutylene moiety derived from butylene oxide, wherein R2O and R3O are in a block or a random distribution; R4 is a linear alkyl with 1 to 18 carbon atoms, a branched alkyl with 4 to 18 carbon atoms or an aryl with 6 to 18 carbon atoms; n and m are each independently integers ranging from 0 to 20 wherein n+m is greater than 0, and p is an integer from 1 to 4. The lubricant composition may have a viscosity index of at least 150, a kinematic viscosity at 100° C. from 2 to 5 centistokes and a kinematic viscosity at −20° C. of at most 600 centistokes.

    Abstract: Embodiments of the present disclosure directed towards synthetic lubricant compositions. In various embodiments, the present disclosure provides a synthetic lubricant compositions including an aromatic amine antioxidant comprising 0.25 to 5 weight percent of a total weight of the synthetic lubricant composition, dithiocarbamate antioxidant comprising 0.25 to 5 weight percent of the total weight of the synthetic lubricant composition, and a polyalkylene glycol PAG comprising 99.25 to 85 weight percent of the total weight of the synthetic lubricant composition, where the synthetic lubricant composition has a total acidic number (TAN) increase of 2 milligrams of potassium hydroxide per gram of the synthetic lubricant composition over 27 days or greater as measured in accordance with modified ASTM D-664, and where the synthetic lubricant composition does not include any of a Group I, II, III, IV base oil.
