A friend of mine suggested a possible reason for this.  Many cars and 
trucks nowadays have electronic fuel injection and have sensors monitoring 
the exhaust gases.  One of these may be an oxygen sensor.

If oxygenated gas changes the amount of oxygen in the exhaust, then the 
sensor reads it and the computer controlling the fuel injection system may 
not work properly resulting in a decrease in mileage.......
