A lubricating oil additive which provides anti-wear properties to a lubricating oil, being the reaction product of 2,5-dimercapto-1,3,4-thiadiazole and a mixture of unsaturated mono-, di-, and tri-glycerides. The additive is preferably formed by reacting a mixture of unsaturated mono-, di-, and tri-glycerides with diethanolamine to provide an intermediate reaction product and reacting the intermediate reaction product with 2,5-dimercapto-1,3,4-thiadiazole. |
