Changes in operating properties of motor oils operating in a hot climate of the Republic of Uzbekistan

This article discusses the effect of changing the operational properties of motor oils on the operation of an engine operating in the conditions of the Republic of Uzbekistan. The quality of engine oils significantly affects the reliability of the engine, fuel consumption and other parameters. Therefore, a high-quality rational selection and use of engine oils is very important. The main reason leading to the formation of high-temperature deposits in spark ignition engines is oxidation processes occurring in the volume of the oil and on the metal surface. These deposits negatively affect the reliability, efficiency and durability of the engine.
