To improve lubricity, Zn-DTP and Mo-complex are used in lubricant as anti-wear additive and friction modifier each other. In this study, The effect of these additives (Zn-DTP and Mo-DTP) will be confirmed and evaluated by four kinds of test methods, Four-Ball E.P test, Four-Ball wear test, Falex Timken test and SRV test.
