A laboratory engine test technique has been developed to stress motor oils such that their relative high-temperature thickening characteristics in severe service can be predicted in a reliable manner. Engine mechanical condition, operating environment, and motor oil composition are important parameters affecting the thickening phenomenon. The mechanisms of oil thickening are complex and may involve nitrogen fixation or soap formation as well as bulk oxidation.
