Abstract: This disclosure relates to a lubricating oil (e.g., gear oil) for use in an electric or hybrid vehicle. The lubricating oil has a composition including one or more lubricating oil base stocks as a major component, and one or more lubricating oil additives, as a minor component. The one or more lubricating oil base stocks include at least one Group IV base oil, or at least one Group V base oil. The lubricating oil has a kinematic viscosity (KV100) from 1 cSt to 7 cSt at 100° C. as determined by ASTM D-445, and an electrical conductivity at room temperature of less than 15,000 pS/m as determined by ASTM D-2624. This disclosure also relates to methods for producing a lubricating oil for a transmission, gear train, gear set, gear box, or gears of an electric vehicle powertrain and methods for improving energy efficiency, while maintaining or improving wear control.

Abstract: Provided is an alternating block copolymer. The alternating block copolymer has an olefin polymer block and an poly(alkyl methacrylate) block. The olefin polymer block has monomeric units of one or more alpha olefins of 2 to 12 carbon atoms that make up 90 wt % or more of the total weight of the olefin polymer block. The olefin polymer block exhibits a number average molecular weight of the olefin polymer block is 1000 to 500,000. The poly(alkyl methacrylate) block has monomeric units of one or more alkyl methacrylates with alkyl side chains of 1 to 100 carbon atoms that make up 90 wt % or more of the total weight of the poly(alkyl methacrylate) block. The poly(alkyl methacrylate) block exhibits a number average molecular weight of 1000 to 500,000. There is also provided a lubricant composition containing the alternating block copolymer and a process for making the alternating block copolymer.

Abstract: Provided is a lubricating oil including a nonpolar lubricating oil base stock as a major component and microcapsules as a minor component. The microcapsules includes (i) a core containing a polar solvent and one or more polar lubricating oil additives having solubility in the polar solvent, and (ii) optionally a shell or membrane enclosing the core. The solubility of the polar lubricating oil additives in the nonpolar lubricating oil base stock is improved as compared to solubility achieved using a lubricating oil containing polar lubricating oil additives in a nonpolar lubricating oil base stock and not containing the microcapsules. A method of improving solubility of polar lubricating oil additives in a nonpolar lubricating oil base stock is also provided. The lubricating engine oils of this disclosure can be useful in automotive, marine, aviation, and industrial engine and machine components.
