    Abstract: A lubricating oil including a lubricating oil base stock as a major component; and a mixture of (i) one or more protected lubricating oil additives having a first performance function, and (ii) one or more unprotected lubricating oil additives having a second performance function, as a minor component. The first performance function and the second performance function are the same. The one or more protected lubricating oil additives are inactive with respect to their performance function. The one or more protected lubricating oil additives are converted into one or more unprotected lubricating oil additives in the lubricating oil in-service in an engine or other mechanical component. A method for controlled release of one or more lubricating oil additives into a lubricating oil. A method for improving oxidative stability of a lubricating oil and extending performance life of one or more lubricating oil additives.

    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.

    Abstract translation: 提供了以非极性润滑油原料为主要成分的润滑油和作为次要成分的微胶囊。 微胶囊包括(i)包含极性溶剂的核心和在极性溶剂中具有溶解性的一种或多种极性润滑油添加剂,和(ii)任选地包封核心的壳或膜。 与非极性润滑油基础油中含有极性润滑油添加剂的润滑油和不含微胶囊的溶解度相比,极性润滑油添加剂在非极性润滑油基础油中的溶解度得到改善。 还提供了提高极性润滑油添加剂在非极性润滑油基础油中的溶解度的方法。 本公开的润滑发动机油可用于汽车,船舶,航空和工业发动机和机器部件。
