    摘要: A method for improving thermo-oxidative stability and elastomer compatibility in an apparatus lubricated with a lubricating oil by using as the lubricating oil a formulated oil including a lubricating oil base stock. The lubricating oil base stock includes a di-alkylated aromatic base stock of the formula: (R1)—(R2)—(R1) wherein each R1 is the same or different and represents a C10-C30 alkyl group; R2 represents an aromatic moiety. The di-alkylated aromatic base stock includes at least 44 wt % dialkylate product. Thermo-oxidative stability and elastomer compatibility are improved as compared to thermo-oxidative stability and elastomer compatibility achieved using a lubricating oil base stock other than the di-alkylated aromatic base stock. A lubricating oil including the di-alkylated base stock of the above formula, and the di-alkylated aromatic base stock of the above formula.
