Three M1083A1 FMTVs were used to test fuel consumption effects of lubricating fluids. An engine oil, transmission fluid, and gear oil were each evaluated to Joint TMCSAE J1321 Fuel Consumption In-Service Test Procedure - Type II specifications over a 42 mile, two speed, test cycle. For the engine and transmission, the baseline OEHDO-1540 oil was evaluated against OEA-30 Arctic oil during testing. The GO-8090 baseline for the axles was replaced with synthetic SAE 75W-140 oil provided by TARDEC. Fuel consumption improvements were seen of 1.5 in the engine, 0.6 in the transmission, and a decrease of 0.84 in the axles. The test results indicate marked fuel consumption improvements when combining fuel efficient lubricants in both the engine and transmission.
