Mineral based oil is being widely used in the field of lubrication. The problems aroused when they found that the disposal of the mineral oil is generally complex and it may contribute to the pollution to the environment. Due to these consequences, this study focuses more on the use of vegetable oil. The purpose of this study is to produce alternative lubricant oil with the addition of the antioxidizing agent into the vegetable oil. Commercialized cooking corn oil is chosen to be the parent oil of the lubricant. The oxidation stability is important to be maximized in lubricant oil. Vegetable oil has very poor oxidation stability due to its content of unsaturated fatty acids which made up of triglycerides structure. The double bond in exists in the structure of triglyceride contributes to higher probability of being attacked by the oxygen thus, making the higher process of oxidation which will then results in the degradation performance of the oil. To resolve this problem, the introduction of antioxidant additive is conducted in this study. Zinc Dialkyldithiophosphate (ZDDP) has the capability of performing the effective antiwear agent as well as antioxidant agent. By dissolving the ZDDP in corn oil using water bath technique, newly developed lubricant oil is produced and sample testing and characterization were conducted. The samples were then tested for its kinematic viscosity, particle count and metal content. In sample characterization, pin on disc test result showed that the friction of coefficient decreased as the concentration increased with increment of load. The greater the amount of ZDDP, the better the results of coefficient of friction and it shows that 5 wt % of ZDDP showed the best characteristics towards lubrication application. the effect of the addition of antioxidant in oil gave a variety of results in each of the test conducted and it is dependable on the optimum concentration of the additive and most importantly the environment that the oil will be introduced to.
