The thesis is focused on the problems of degradation of engine oils of the same viscosity class 5W-30.The first part of the thesis is describing lubricating systems and their component parts. The thesis also focuses on the division of oil in each classification and description of its properties. Samples of the oil have been taken from two cars with identical diesel engine, but with different total traveling distance. Attention is paid to the amount of structural metals, contaminants and additives in both oils, and throughout the oil usage interval. The results are interpreted graphically and various dependencies are modeled using appropriate regression functions. Thesis compares the mechanical and physical properties of engine oils, depending on mileage. The conclusion summarizes the evaluation and the results obtained.
