The method of spectral analysis of a liquid sample of spent oil using a rotating disk electrode is tested as a means for practical diagnosis of motor vehicle engines. Preliminary results indicate stability of concentration of wear products in spend oil, regardless of the mileage of the vehicles. Hidden defects in engines can be discovered in a timely manner on the basis of sharp increases in the concentration of corresponding elements in spent oil.
