The in-house investigation described was to determine whether the industry- and military-standard oil-change interval of 100 hours could be extended for the 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 specified for the preproduction model 5,000-hour reliability and acceptance tests. In Phase II, the oil-change and filter-change intervals were established by the condition of the oil. The condition of the oil was monitored by chemical and spectrometric analyses. Based on the test results and the urgency of the current energy crisis, the Project Manager, Mobile Electric Power, issued an oil-change policy for the 15-through 200-kW size generator sets 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.
