Abstract
Elevated temperature liquid testing apparatus and methodology in which a thin film of test liquid and a reactant/control gas are provided about the top of a depositor member that is surrounded by a special mantle, for example, a substantially cylindrically walled glass mantle. As an oxidative engine oil test, it may mimic turbocharger conditions of a modern internal combustion engine. For example, employing moist air, the apparatus can test a thin film of engine oil for oxidation deposits at a predetermined temperature, say, 285° C., 290° C., or cycled between 285° C. or 290° C. and 320° C. or 330° C.
