Abstract
Lubricant, as a factor that cannot be avoided in the engine-fuel-lubricant system, besides its normally known lubricating function, plays a highly important role in detecting the efficiency of operation and the condition of engine. This is obtained by a systematic observation of oil in application and by a permanent contact between user and motor oil producer. For this reason, but also in order to prove the quality of produced motor oil, applicative tests are being performed for the purpose of establishing various set goals. “Hrvatske željeznice” (HŽ) have in their tow pool a considerable number of locomotives equipped with diesel engine type 645 E, produced by the General Motors Corporation. These are locomotives of the 2 062 series. After general overhaul performed on the locomotives upon request of the GMC service, and because of their own interest in observing the repaired engines, HŽ are, together with “Maziva Rijeka” (specialized locomotive motor oil producer), implementing the observation of oil in field service.
The paper presents the so far results of the trial tests, with comments and conclusions, in the long run confirming the need for trial tests and their payability. It furtherly points out the importance of "after sale" manufacturer services, and directs the users in Croatia to the domestic lubricant producer whose quality matches that of foreign competitors, while the vicinity, skilled experts and laboratory support ensure a correct and optimal utilization of the lubricant.
