Lubricating oils are substances of mineral or synthetic base responsible for forming a protective film, which prevents direct contact between two surfaces that move with each other. The lubricant mixture is formed by the addition of additives to the base oil obtained in the distillation of petroleum. When used oils are released directly into the environment or when uncontrolled burning causes serious soil, water and air pollution problems. Recycling the lubricant means applying physical-chemical processes on the used oil, making it possible to obtain base oil, a raw material that can be reused to obtain lubricants. The objective of the present work is to evaluate the recent processes of recovery of used automotive lubricating oils.
