Cost and environmental benefits of extended-drain engine lubrication were evaluated by means of a two-year field program at Letterkenny Army Depot, Pennsylvania. Four MIL-L-46152 crankcase lubricants two mineral and two synthetic-base were utilized in routine post operation. Each lubricant was assigned to one of four 25-vehicle fleets, and each fleet then operated exclusively on that lubricant. During this time there were no engine failures that could be attributed to the extended-drain program. Therefore, it is concluded that a extended-drain engine operation has potential for both economic and ecological benefits to Army field operations, and b the synthetic lubricants employed showed no particular performance advantages over the mineral oils. Consequently, the higher cost of synthetic lubricants would make them less attractive for widespread Army utilization.
