Abstract: The degradation products of oils and decrease of additives content were studied by the FTIR method. The wavenumbers of oxidation, nitration, sulfocation products and antioxidant additives bands of infrared spectra of airborne engine mineral lubricants were precisely identified. These areas were identified on the basis of the analysis of 250 samples of the used oils of the oil MS-8P. Levels of degradation products of this oil were determined using mathematically generated calibration curves.
