Used oil is a hazardous and toxic waste. When this waste is disposed off into the environment, it harms the environmental. The conversion of used oil to diesel fuel candidates has been studied utilizing a simple distillation method. The distillation is carried out on used oil with a zeolite catalyst placed on a distillation tower. Distillation temperature variations of 360 °C, 380 °C, 400 °C are applied to used oil to produce fuel distillates. Tests were carried out on distillates in flashpoints using ASTM D93, Kinematic Viscosity using ASTM D445 and Cetane Index using ASTM D4737. The results of the calculated cetane index test showed the respective values of 48.44, 48.46 and 48.84. The viscosity at 40°C (mm 2 sec) resulted in 1.57, 1.64, and 2.00. While the flashpoint value shows the number 27°C, the temperature variation does not affect the flashpoint value. The results of this test, when compared with Dirjen Migas Specification, the flashpoint value has not been fulfilled although with the addition of NaOH. A distillation temperature of 400°C only fulfils the minimum kinetic viscosity. In contrast, the Calculated cetane index has been fulfilled, with the largest value generated at a distillation temperature of 400°C.
