All hydraulic and lubricating oils are formulated with oxidation inhibiting additives. When oxidation-inhibiting additives are depleted, oil oxidation progresses, TAN raises and varnish is produced. In order to know depletion of oil oxidation inhibitors, RBOT  and voltammetric analysis  have been used. However these analyses did not tell us how much top-up of new oil is needed or sufficient. This paper demonstrates a simple method to know how much top-up is sufficient to use the oil without having varnish problems.
