Several kinds of 1H-tetrazole-1-acetic acid esters containing mercaptobenzothiazole and dialkylenedithiocarbamate, which are potential environmentally friendly lubricating grease additives, were synthesized. The tribological properties as lubricating additives in 100N base oil, vegetable oil, diester oil, polyol ester oil, Li-soap greases and vegetable greases were evaluated using 4-ball tester and SRV tester. The results do not show that the esters have wear reducing characteristics for all concentrations at an ambient load. It is clear that the esters at the concentration of 1 wt% in Li-soap greases is effective at reducing the wear, which were EP value of 400N~1, 100N, COF value of 0.113~0.137, and WSD value of 0.474~0.591 depending on the structures of the esters.
