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 die lubricating oil in-ser - vice in an engine or other mechanical component. A method for controlled release of one or more lubricating oil additives into a lub - ricating oil. A method for improving oxidative stability of a lubricating oil and extending performance life of one or more lubricating oil additives.
