Beschreibung
Zusammenfassung:	A method for extending performance or service life of a lubricating oil in an engine or other mechanical component lubricated with the lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one microencapsulated lubricating oil additive, as a minor component. The at least one microencapsulated lubricating oil additive includes an encapsulating material (e.g., polymeric matrix) and a core material (e.g., at least one lubricating oil additive) encapsulated by the encapsulating material. A method of improving solubility, compatibility and/or dispersion of lubricating oil additives in a lubricating oil base stock. A method for controlling release of a lubricating oil additive into a lubricating oil. A lubricating oil having a composition including a lubricating oil base stock as a major component, and at least one microencapsulated lubricating oil additive, as a minor component.
