Description
Summary:All in-house investigation is described to determine whether the industry- and military-standard oil change interval of 100 hours could be extended for DOD Family of Diesel Engine Driven Generator Sets using MIL-L-2104C specification lubricating oil. The investigation was conducted in two phases. In Phase I, the oil and filter were changed each 100 hours in accordance with the servicing and maintenance guide for the preproduction model 5,000-hour reliability and acceptance test. In Phase II, the oil and filter change interval was established by the condition of the oil. The condition of the oil was monitored by chemical and spectrometric analyses. Based on test results and the urgency of the current energy crisis, the Project Manager, Modile Electric Power, issued an interim oil change policy directing that the oil and oil filters be changed each 300 hours of engine running (normal running conditions) or after 6 months, whichever comes first. It is conservatively estimated that a savings in excess of $1.5 million a year can be realized by the military with the implementation of this directive.
