Description	Three experimental approaches, selected for analysis of the engine oils and described above, are surely sufficient for the needs of presented research. The spectrometry was used for determination of presence of selected chemical elements and especially metals in oil. Particles monitoring was employed in order to describe the amount, type, and size of friction particles. The temperature dependence of dynamic viscosity was evaluated by use of rotary viscometer. In case of all three approaches it is advantageous to compare the measured values with the results received for unused engine oil of the same marking and viscosity index. If the degradation of oil is classified as low or medium, it is possible to increase its service life for several thousands of kilometers. But it is necessary to monitor the condition of the oil in appropriately selected period - e.g. each 3,000 km. If the degradation of oil is found as higher or high, it is necessary to change the oil immediately. The change should obviously include the oil filter.
