The article presents the results of the investigations of turbocharger shaft bearing using different kinds of lubrication conditions (dry friction and lubrication with different kind of oils). In particular, the wear of the turbocharger shaft surface was evaluated. One of the most frequent failures is the seizure of the turbocharger shaft in the slide bearing, causing its rotation, which leads to destruction of the assembly and costly repairs. On the basis of the conducted tests, it was found that the average value of representative breaks surface on the turbocharger shaft are reduced using of a less viscous oil. Similar situation was seen using new oil instead overworked oil – it had an influence on the value of diameter of breaks.
