Abstract
A model for the loss of oxidative stability of engine oil is presented in which the oil in an operating engine is assumed to be in one of three categories: oil which is lost from the system, oil in which the oxidative stability is reduced or lost as a consequence of exposure to harsh conditions, and the bulk of the oil which is neither lost nor reacted. Graphical examples are presented to show how various events or conditions in an engine, for example, oil consumption, oil additions, residual oil from the previous oil change period, and the presence of contaminants in the oil, affect the oil's oxidative stability.
