An oil treatment system for reclaiming used oil including apparatus for feeding the oil first through a filter for removing solid contaminants therefrom then through a vaporizer unit wherein it is heated under a vacuum while in a flowing film form to remove water, dissolved gases and volatile contaminants therefrom, and automatic control devices whereby treated oil cannot be discharged until it has been subjected to heat and vacuum in the necessary degrees, and whereby the system, once initiated by a starting or stopping signal, is automated to initiate or terminate operation of the various components of the system in a sequence operable to produce efficient, trouble-free operation of the system as a whole.
