Eighteen spark ignition engines from U.S. Army administrative and light-tactical vehicles, which were part of a fleet test to determine the effects of operating such engines with gasohol as a fuel, were shipped to the U.S. Army Fuels and Lubricants Research Laboratory (USAFLRL) for after-test inspections. Twelve of the engines were operated with gasohol as a fuel, and six of the engines were operated with unleaded gasoline. Each engine was disassembled for inspections which included visual inspection, wear measurements of selected components, deposit ratings in accordance with CRC rating methods, and photographs of selected parts. No significant differences between engines operated with gasohol and those operated with unleaded gasoline could be determined by any of the inspection methods used. Consideration of the data generated from the inspections support the conclusion that gasohol may be successfully utilized in the U.S. Army's administrative and light-tactical vehicles.
