An electric oil refining apparatus for motor vehicle internal combustion engines designed to remove liquid and solid contaminants from oil which is then recycled. The oil exits from a single small orifice into a vaporization chamber where, due to sudden change of temperature and pressure, the liquid contaminants separate from the oil. The stream of oil is then deflected against a heated concave cup which vaporizes liquid contaminants, and allows oil to flow over the floor of the vaporization chamber and back to the internal combustion engine of the motor vehicle for reuse. A filter is provided at the input to the orifice, thereby avoiding clogging of the orifice.
