Abstract :Refining of waste mineral oils is usually done by distillation or acid/clay methods, or a combination of both. In this study, waste oil refining was carried out in order to obtain higher efficiency than acid /clay method by using more environmentally friendly physicochemical methods which could be an alternative to acid /clay method and distillation methods. For this purpose, demetalization and decolorization stages were applied in order. It was observed that the oils obtained had equivalent parameters to base oils.
