Large amounts of used lubricating oils are generated from the automotive and process industries and pose environmental hazards if not properly managed. In this study, the potential to re-refine used lubricating oils for reuse was investigated using a combination of vacuum distillation, solvent extraction with additive for maximum performance. Used oils were collected from a local garage and were first dehydrated at 240 °C and varying pressure of 4-12 bars under vacuum distillation. Solvent extraction of the oils was done using Methly Ethly Ketone (MEK) as solvent with varying ratios from 2:1 to 6:1 at mixing temperatures of 60 °C. Afterwards, the MEK and oils mixture underwent atmospheric distillation at 80 °C to allow separation of the oils and the MEK. During the re-refining process, the amount of water removed, the ash content, sulphur content, viscosity, specific gravity, flash point and pour point were measured. Optimum oils yield of 94 (wt %) was achieved at a solvent to oil-ratio of 6:1. Re-refining of the used oils resulted in 73% reduction in the sulphur content, 76% reduction in ash content and 64% water removal. The re-refined oil’s viscosity of 90 cP, flash point of 160 °C, specific gravity of 0.91 and pour point of -12 °C. The re-refined used oils propertied were almost similar to those of the virgin oil. The re-refined oils employing zinc dialkyl dithiosulphate as an additive exhibited physicochemical characteristics similar to the virgin lubricating oils and can be adopted for re-use.
