The thesis is focused on the operational degradation of engine oil in four-stroke motorcycles and is dividend into two parts. The first part of the thesis is focused on the theoretical part, where tribology, lubricants and lubrication system is described. The experimental part of the work is focused on examineting engine oil degradation due to mileage. First, the monitored motorcycles and used oils are described. The results of measured density, viscosity and content of individual substances occurring in oils are described. Finally, a discussion and comparison of resulted trends with other experiments is performed.
