NOVELTY - Treating regenerated lubricating oil involves filtering the waste lubricating oil, heating after the rough filtration to 60-65degrees Celsius, removing impurities, and leaving the oil. The oil fraction obtained by sedimentation is refined, and the oil fraction is retained under the conditions that the relative vacuum degree is ( 0.08) megapascal, at 50 60degrees Celsius. The obtained oil is heated to 50-60degrees Celsius, further layered the oil and water, and left the oil layer to obtain the regenerated lubricating oil. USE - Method for treating regenerated lubricating oil used for the recovery and treatment of waste lubricating oil. ADVANTAGE - The method has the advantages of no pollution to the environment and good treatment effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a regenerated lubricating oil.
