An evaluation of fuel consumption using three FMTVs showed the potential for significant improvement using advanced lubricants. For the engine and transmission, the baseline OEHDO-1540 oil was evaluated against a candidate Single Common Powertrain Lubricant SCPL. The GO-8090 baseline for the axles was replaced with synthetic SAE 75W-90 oil selected by TARDEC. Over a two-speed highway cycle, an average improvement of 6.1 was observed. When operated on a cycle which included stop-and-go transients, the average fuel consumption improvement increased to 7.8.
