FIELD: purification of waste of motor oil. SUBSTANCE: water (its quantity being 0.5-0.7 mass %) and ethanol (its quantity being 3-4 mass %) are consequently added into waste motor oil. Thus prepared mixture is affected at 60-70 C within 1 h by indirect electric field having intensity 1-2 kV/cm. The process is followed by filtration. EFFECT: improves efficiency of the method. 1 tbl
