A series of high temperature oils has been evaluated in a high temperature thin film oxidation unit. The apparatus measures oxygen consumption and deposits formed by the oils in thin films on a rotating heated disk. Data were obtained at several film thicknesses and contact times which were varied by changing the rate at which the oil is passed over the disk. At the optimum oil flow rate, correlation of disk cleanliness with engine deposition data was excellent. A brief exploratory study indicated that provision for bulk oxidation in addition to the high temperature thin film oxidation could further improve the thin film oxidation unit as a screening tool.
