Korbička, Jiří
The thesis deals with motor oil with the same viscosity class 5W-30. Five samples were monitored for new oil and two samples of the used motor oil of the same specification. Their physical and mechanical properties were compared depending on temperature. The first part is focused on the production of motor oils and their classification. In subsequent chapters their functions and features are described. The last part includes the description of methodology, the actual measurement, graphical and statistical processing of data, comparing results and conclusions.
