The paper deals with the results of the study on the purification process of used mineral and semi-synthetic motor oils in the presence of crystalline urea. The effect of the process main factors (the amount of the main reagent, time, and temperature) on the performance indicators of purified motor oils was studied. Used mineral and semi-synthetic motor oils for gasoline and diesel engines were purified under the established optimal conditions. The results of X-ray-fluorescence and IR-spectroscopic studies on the chemical composition of motor oils purified in the presence of urea are presented.
