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 TMC/SAE 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 OE/HDO-15/40 oil was evaluated against OEA-30 Arctic oil during testing. The GO-80/90 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. The original document contains color images.
