摘要：
A lubricant composition comprising a Group I, II, III or IV hydrocarbon oil and a polyalkylene glycol, the polyalkylene glycol having been prepared by reacting a C8-C20 alcohol and a mixed butylene oxide/propylene oxide feed using a double metal cyanide catalyst catalyzed oxyalkylation process, and wherein the lubricant composition remains clear and shows no phase separation at temperatures equal to and greater than the pour point of the hydrocarbon oil is provided. A method for making a lubricant composition is also provided.
