Abstract: Analysis of Electrohydrodynamic (EHD) Flow Phenomenon through deformation on the surface of new and used lubricating oil has been carried out. Positive corona plasma discharge was generated using a reactor with a point to plane electrode configuration. Voltage (V) is increased from 0 kV until arc discharge. The applied voltage interval is 0.2 kV. The distance between the electrodes (d) was varied from 4 mm to 14 mm with an interval of 2 mm. The results showed that the largest current of 43 µA was obtained at the characterization carried out at a distance between the electrodes of 14 mm without a sample, while the smallest current 0,5 µA was obtained at the distance between the electrodes of 4 mm in the presence of a new lubricant sample. The ion wind direction is influenced by the applied voltage and the distance between the electrodes. The value of the ion wind angle decreases with increasing distance between the electrodes, and the ion wind angle increases with increasing voltage. The value of the ionic wind angle in the presence of used lubricating oil samples is greater than that of new lubricating oil. The radius of deformation of the lubricant by the ion wind is affected by the applied voltage and the distance between the electrodes. The radius increases with increasing distance between the electrodes. The radius of deformation in used lubricating oil is greater than in new lubricating oil. Termination of applied voltage, circle deformation will close. The closing of the circle deformation in new lubricating oil is faster than used lubricating oil
