Abstract
A device for filtering and refining oil being cycled through an engine includes a container, a cover having an evaporator plate incorporated therein, and a filter cartridge. The evaporator plate is dimensioned to conform to a predetermined inner shape of the container to sealably fit therein inhibiting the purified oil to cycle back through the filter. The configuration is such that a predetermined amount of oil is directed into the device and first passes through the filter cartridge and then passes over the evaporator plate. The contaminants evaporated from the oil pass through a vent in the cover. The filtered and refined oil is then directed back into the engine.
