Values of surface tension of these additives were measured in oil phase and consequently CMC was determined for all additives and their mixtures in oil phase. The efficiency of these additives depends on their chemical structure and the presence of ether oxygen brings about the association of the surfactant with metal surface, hence very good

5 DISCUSSION. ZDTP was originally formulated as an anti-oxidant additive but it soon became apparent that chemicals of this sort also significantly reduced the friction between sliding steel surfaces and enhanced their capacity to withstand repeated contacts without the onset of scuffing. Their success as effective anti-wear additives is

Therefore, the combinations of the antioxidants along with other lube additives in a lubricating fluid need to be optimized to prohibit or minimize antagonism. It has been shown that anti-wear and antioxidant properties of ZDDPs have been adversely affected by some additives such as detergents and dispersants (sulfonates, phenates and salicylates).
