Higher Octane Fuel Could Add MPG, SAE Panel Says

In a world of higher octane gasoline -- in which 95 would replace 87 and become the new regular -- automakers could more easily and affordably meet stringent fuel economy standards as well as reduce carbon dioxide emissions.
During a panel discussion this week at the SAE World Congress here, representatives from Ford Motor Co., General Motors, Chevron Energy Technology Co. and an ethanol trade group agreed that raising octane would allow gasoline engines to run more efficiently, boosting fuel economy between 3 and 6 percent and lowering CO2 emissions by around 2 percent.
