  A number of metals are found in used lubricating oil. In this   article, performance of solvent extraction followed by adsorption   on magnesite has been studied for removal of metals from used   oil. The suggested process is one of the efficient methods to   remove not only sludge, but also the metals either present in the   lubricating oil as additives or picked up by the oil during its   working life. The re-refined oil has metal content comparable   with base oil. In some cases, even lower metal content has been   observed.
