Description:

Because of the concern that re-refined oil was causing engine failures, a study was initiated to compare the wear effects of re-refined and virgin oils using the two Detroit Diesel engines in a ferryboat that would experience similar duty cycles, weather, and hours of operation. Ideally, both engines would have been rebuilt to the manufacturer’s specifications and the precise dimensions of bearings and other internal wear components documented. The condition of both engines was essentially the same for later comparison. One engine was to run on virgin oil and the other engine on re-refined oil. Two oil samples were taken every oil change and analyzed. Halfway through the program the oils were to be switched. During this process, some of the results were inconsistent due to a mix up. Thus, the results of these tests were limited. Inferences could be made from the test data, however: there was no indication of an effect between re-refined oil versus virgin oil; the engines should run on oil specified by Detroit Diesel, whether virgin or re-refined; and that engine oil changes should be much shorter than is typical for the ferryboat.
