A method of reclaiming used motor oil for further use is disclosed comprising (a) admixing used impurity laden motor oil with an effective amount of acetone as a flocculating agent and an effective amount of a second ketone as a wetting agent thereby forming an oil impurity flocculent mixture; (b) subjecting said mixture to a force such that a heavy phase and a light phase are formed, wherein said light phase is comprised of lean motor oil, acetone, and a second ketone, and wherein said heavy phase is comprised of flocculated impurities, any remaining acetone, and any remaining second ketone; and (c) separating said light phase containing said lean motor oil from said heavy phase containing said flocculated impurities. Preferably the second ketone is diisopropyl ketone, though other second ketones are also functional.
