The first year's operation on unleaded gasoline has been completed with more than 20,000,000 vehicle miles and many hours accumulated on Material Handling Equipment and other ground power equipment. It can generally be concluded that Phase II has proven that Army gasoline powered equipment and vehicles can be operated during their normal daily activities on unleaded gasoline in the octane quality range used in the program for long periods of time without any apparent fuel economy penalties and with no increase in maintenance or operating costs. During Phase II there were no engine failures that could be attributed to the unleaded gasoline, there was no evidence of engine performance degradation; in fact, there were driver reports of better engine performance on the unleaded fuel. This is not at all surprising since cleaner burning engines had been observed during Phase 1 and longer life was obtained from spark plugs during the field evaluation. (GRA)
