ABSTRACT:
A method is disclosed for measuring the remaining useful life of an ester-based lubricant containing at least one antioxidant species. A lubricant sample is mixed with a solvent, an organic base and an electrolyte to produce an analysis sample. The analysis sample is placed into an electrolytic cell and subjected to a cyclic voltammetric analysis, whereby a varying electric current is produced within the cell. The current during the cyclic voltammetric analysis is measured and recorded. Remaining useful life for the lubricant is then determined from the average maximum reduction current wave height produced.
