The effect of the chemical structure of a lubricant on the complexity of friction and wear under boundary conditions is studied using a pin-on-disc machine and a four-ball wear tester. The two test units are used to compare the friction and wear characteristics of four hydrocarbon fluids. Three vegetable oils and three additives are also evaluated in the four-ball wear tester to demonstrate the importance of chemical structure of the base fluids and the additives on the effectiveness of the additives in controlling friction and wear.
