The aim of this study is to extract the fuel from waste lubricating oil and recycle the lubricating oil by distillation process. With this aim in mind, used lubricating oil is collected and is filtered to remove contaminants such as dust, carbon soot, metal particles, gum-type materials and other impurities. The additives, known as sodium carbonate (Na2CO3), zeolite (Na2Al2Si3O10•2H2O) and calcium oxide (CaO) are used to investigate the variations in density, viscosity, flash point and pour

... t of waste lubricating oil. The filtered oil samples are blended separately with additives in different mass ratios of 2%, 4%, 6%, 8% and 10%. The mixed samples are exposed to distillation process to extract fuel from the used lubricating oil. The blend (fuels obtained + fresh diesel) such as density, flash point, viscosity, sulfur content, heating value are examined and found to be comparable with fresh diesel. Solvent extraction process is performed in order to extract the base oil by using different solvent like 1-Butanol, 2-Propanol and Methyl Ethyl Ketone (MEK) in different ratio of 2:1, 4:1, 6:1 and 8:1. The parameters of recycled lubricating oil and fresh lubricating oil are found to be similar. Thus, the recycled lubricating oil can be recycled without harming surroundings.
