Abstract�� In this experiment, regeneration of  the used engine oil was obtained by the reaction of   the deteriorated part in the lubricating oil with  the sodium liquid ammonia solution as chemical reagent.  The experimental results show that the optimal conditions are: the addition of the sodium liquid ammonia solution proportion is 3��2 mL(based on 100 g used oil ), refining temperature  40 ��,viscosity index  100�� And after the clay adsorption to improve the color degree of the regeneration oil, the various index of the recovered oil can meet the requirement of HVI standard.
