Abstrakt: This paper addresses tribotechnical diagnostics, specifically by examining the properties of the engine oil (MO) type i-Sigma top MS; SAE 10W-40 used in the IVECO CROSSWAY bus with a higher number of total mileage from the inter-vehicle standard. In the abstract of the paper, the characteristics of the measured technique, tribodiagnostic instruments of measurement and a more detailed specification of the oil properties and the monitoring of its gradual degradation during long-term operation are presented. Long-term operation in the sense of the article means a continuous mileage run of more than 200 km (one race without stop) and a MO temperature in the range of 80 ºC to 130 ºC. All measurements were carried out in the tribodiagnostic laboratory of the Department of Mechanical Engineering of the Armed Forces Academy of General M. R. Štefánik (hereinafter referred to as „AOS") in Liptovský Mikuláš.
