Never Drain Engine Oil Technology, Phase 2
Abstract
As the second phase of a program to evaluate methods of extending the life of engine oils, an agreement was reached with Thompson-Ramo-Woolridge, Inc. (TRW) to evaluate an experimental low-blowby piston ring assembly in an L-141 engine. The rings were initially evaluated using an engine dynamometer and were then installed in an M-151 Military Utility Tactical Truck (MUTT) for an extended road evaluation. All tests were conducted using a qualified MIL-L- 2104C/MIL-L-46152 grade 30 lubricant and unleaded gasoline meeting VV-G-001690A specifications. From the results of the 35,400-km (22,000-mile) road evaluation, it appears that these low-blowby piston rings, in conjunction with high-quality level MIL-L-2104C/MIL-L-46152 qualified oils, would allow no-drain operation for its 32,000-km (20,000-mile) lifetime of the M-151 vehicle when operated in a high-mileage accumulation, high-temperature model.
