Abstract

The purpose of this work is an experimental study of changes in the quality of oil and the establishment of the period of its replacement when compared with the defective indicators. During engine operation, engine oils undergo chemical changes under the influence of temperature and oxygen in the air – they are oxidized. In order to achieve this goal, we, by agreement with the bus fleet, took samples of motor oils of 15W-40 buses every 2500 km of mileage and were analyzed according to the main quality indicators. The experimental data obtained by us on the change in the base number are taken into account, we recommend introducing detergent additives into the engine oil when the bus mileage reaches 7500 km.
