ABSTRACT:
A method and apparatus for testing the lubricating quality of oil. The apparatus comprises a pair of dissimilar, spaced-apart electrodes, a voltage indicator and circuitry interconnecting the electrodes and the voltage indicator. Upon placing an oil sample between and in contact with the electrodes, oxidation by-products in the oil, built up therein due to deterioration or breakdown of the oil, react with one of the electrodes to form an oxide thereof. The oxidation of the electrode produces a corresponding voltage reading which indicates the lubricating quality of the oil.
