Abstract: A lubricating oil base stock including one or more monoesters represented by the formula (I), (II), (III) and (IV) as defined herein. The lubricating oil base stock has a high temperature high shear (HTHS) viscosity of less than about 1.7 cP as determined by ASTM D4683, and a Noack volatility from about 15 to about 90 percent as determined by ASTM D5800. A lubricating oil containing the lubricating oil base stock including one or more monoesters represented by the formula (I), (II), (III) and (IV) as defined herein. A method for improving one or more of thermal and oxidative stability, solubility and dispersancy of polar additives, deposit control and traction control in a lubricating oil by using as the lubricating oil a formulated oil containing the lubricating oil base stock including one or more monoesters represented by the formula (I), (II), (III) and (IV) as defined herein.

Abstract: A lubricating oil including a lubricating oil base stock as a major component, and one or more lubricating oil additives having at least one protected active group, as a minor component. The one or more lubricating oil additives having at least one protected active group are converted into one or more lubricating oil additives having at least one unprotected active group in the lubricating oil in-service in an engine or other mechanical component. Compositions including one or more lubricating oil additives having at least one protected active group. A method for improving solubility of one or more lubricating oil additives in a lubricating oil. A method for improving oxidative stability of a lubricating oil and extending performance life of one or more lubricating oil additives. A method for improving friction control in an engine or other mechanical component lubricated with a lubricating oil.
