The goal of the Army Single Common Powertrain Lubricant (SCPL) program is to develop an all-season (arctic to desert), fuel efficient, multifunctional powertrain fluid with extended drain capabilities. SCPL must be able to properly function in various mechanical applications including engine crankcase lubrication, powershift transmission operation, and some hydraulic system operation. Several diesel engine crankcase oils were evaluated in powershift fluid bench tests to determine the feasibility of using engine oil in this application. While none of the engine oils passed all the bench tests, overall technical feasibility was demonstrated as evidenced by passing or near passing results with the slate of engine oils tested.
