The tests have been caried out on "ŞAHİN MOTOR YATAKLARI» model 17-M-Motor for different oil types and number of revolution. During the test, the first, number of revolution of crankshaft which one ? of the wearing parameters was' fixed, but different oil types were used. After, secondly, the number bf1 revolution of crankshaft were also changed. At each condition, the influence of wearing on the' mlain bearings was examined. As result, at the end of the test, it can be' said that the less wearing on the main bearings occurs in the test heating medium for different oil types used.
