DEPENDENCE OF CHANGES IN THE PROPERTIES OF MOTOR OILS ON THE OPERATING CONDITIONS OF THE ENGINE

The purpose of this work is to study the performance characteristics of the M-10V2 engine oil used in diesel engines. During the operation of the controlled vehicles, tests of samples of fresh oil, working and spent with mileage recording were carried out. The main physical and chemical parameters of properties (viscosity, alkaline number, dispersing and stabilizing ability, moisture content, fuel, mechanical impurities, ash content, etc.) affecting the operational characteristics of the oil have been studied
