Production of biodiesel was involved transesterification process that implicated the reaction between used cooking oil and methanol with aid of KOH. The reaction was carried out at 15 min, 30 min, 60 min, 90 min, and 120 min to evaluate the effect of reaction time on the yield of fatty acid methyl ester (FAME). The highest yield of FAME was obtained at reaction time 60 min. Besides that, the yield of fatty acid methyl ester was studied by changing  the reaction temperature at 30°C, 60°C, 75°C, 90°C, and 120°C. The maximum yield of fatty acid methyl ester (FAME) was obtained at 60°C.All samples of biodiesel at different reaction time and temperature were contained high amount of bounded glycerol.Biodiesel was successfully reduced 39.2 percent opacities level of smoke released by diesel engine.Biodiesel was less efficient in performance of engine when compared with diesel fuel.
