Based on Standard Test Method for Determination of Moderately High Temperature Piston Deposits by Thermo-Oxidation Engine Oil Simulation Test-TEOST MHT（ASTM D7097-06a）,the TEOST was used to evaluate the effect of antioxidants,dispersants and detergents on the high temperature detergency of engine oils.Besides,the phosphorus volatility of engine oils was measured by the TEOST MHT test,and the impacts of ZDDPs with different structures on the phosphorus volatility were estimated.The TEOST MHT test is capable of measuring the phosphorus volatility of engine oils,with very good discrimination and precision.
