Description
Summary:The U.S. Army has a desire to consolidate multiple MIL specification fluids into a single specification, or Single Common Powertrain Lubricant (SCPL). The application of this fluid would include engine lubrication, power shift transmission operation, and limited use in hydraulic systems, and must be designed to operate in ambients ranging from low temperature arctic, to high temperature desert type conditions. The U.S. Army TARDEC Fuels and Lubricants Research Facility (TFLRF) located at Southwest Research Institute (SwRI) has aided TARDEC in the initial development of the SCPL. This report covers the testing of two revised candidates identified in TFLRF Report No. 418. Testing included high temperate endurance in the General Engine Products 6.5L(T) diesel engine to assess engine protection and oil performance at elevated temperatures, 2-cycle diesel engine compatibility using the Detroit Diesel 6V53T, multiple industry standardized transmission tests (Allison C4, Caterpillar TO-4, John Deere JDQ) to assess frictional performance and driveline durability, and quantification of fuel consumption improvement over standard military oils through viscosity reduction in the SCPL. This report is the second in a series covering the SCPL development, and focuses on the refinement of two initial SCPL candidates identified during research reported under TFLRF Interim Report 418, Single Common Powertrain Lubricant (SCPL) Development (Part 1), ADA577551.
