RESEARCH OF PERFORMANCE OF SYNTHETIC MOTOR OILS INDICATORSUSED IN GASOLINE ENGINES OF PASSENGER CARS

Abstract

The purpose of this work is to study the kinematic viscosity and the alkaline number of synthetic motor oils depending on the mileage of a passenger car.

The scientific novelty of the work is in obtaining new experimental data on changes in the kinematic viscosity and the alkaline number of synthetic motor oils of domestic and imported brands with an increase in vehicle mileage.

The introduction contains brief information about the requirements for the kinematic viscosity and alkaline number of synthetic motor oils used in gasoline internal combustion engines of passenger cars.

The main part describes the methodology for conducting research to determine the kinematic viscosity of motor oils, measured at 40 and 100 °C, and the base number depending on the mileage of the vehicle. It has been established
that it is advisable to use synthetic Lukoil Lux SAE 5W-40 and Motul SAE 5W-30 X-Clean engine oils for Skoda Rapid passenger car gasoline engines. This is due to the fact that during the operation of the car, the studied performance indicators of these oils decrease less intensively, which in turn indicates a higher quality of oils.

The results of the research will be useful to mechanical engineers when choosing synthetic engine oils used in gasoline internal combustion engines in order to increase the reliability and operability of the main engine components.
