The U.S. Army Tank Automotive Research, Development, and Engineering Center TARDEC has initiated the construction and development of a stationary axle efficiency test stand to allow for laboratory based investigation of Fuel Efficient Gear Oils FEGO and their impact on vehicle efficiency. Development work using the stationary axle efficiency test stand was completed using hardware representative of light and medium duty tactical wheeled vehicles. Stationary axle efficiency testing was conducted following a draft Federal Test Method FTM using developmental and commercial oils. The most differentiation of efficiency between tested lubricants was achieved in the low speedlower load operating conditions of the FTM cycle, while efficiency results at the higher speedhigh load operating conditions showed significantly tighter grouping. Overall, results tended to show increased efficiency trending with reduced viscosity.
