Abstract:
The movement of the elements of machine systems with the least possible loss of energy and prevention of their damage is the goal of diesel engine manufacturers. In this paper, an analysis of the application of semi - synthetic motor oil is presented. Physical and chemical analyzes of engine oil used in agricultural machinery, i.e. in tractors CASE 9220, John Deere 8320 and John Deere 6820, were performed. Conclusions are given regarding the application of engine oils in diesel engines from the aspect of degradation, i.e. the impact on the elements that are exposed to the wear process.

Key words:
motor oil,contamination,friction coefficient,time of interrogation of oil.
