New designs of internal combustion engines require the use of engine oils that can cope with more demanding conditions, primarily with greater loads and higher temperatures. The requirements of recent years have led to a wider use of modern base oils and specially designed additive packages. This avoids the formation of impurities and changes in viscosity as a result of shearing of the viscosity additives under high loads. The article discusses the important problem of oil aging during operation and the impact of this phenomenon on the operation of internal combustion engines. The influence of oil service life and its replacement on the emission of toxic exhaust gas components was discussed, and the results of research on the effect of oil service life on changes in their viscosity were presented.
