Today the world cares about recycles of industrial wastes in order to reduce the pollution in the environment and economic purposes. Waste lubricating oil is one of these residues that cause water, air and soil pollution when disposed of without treatment. In this work, vacuum distillation technique was applied to purify waste lubricating oil after primary treatments such as separation of water and filtration. Gas chromatography analysis was used to study the changes in chemical structures of the hydrocarbon fractions of treated lubricating oil and comparison them with those in fresh oil. The results showed that, the C10-C15 hydrocarbon fraction is increased and the C20-C25 is decreased for all type of hydrocarbon chemical structure after use of the lubricating oil. On the other hand, the comparison of hydrocarbon fraction of waste lubricating oil and gas oil showed that, there is close similarity between them according to the results of gas chromatography analysis.
