I did forget to make one point about Ethanol or Methanol as a fuel. As you may know engines running on pure alky will make more power than a gas motor, hence Gas, Alky, and Top fuel nitromethane classes. The trick there is the motor is set up for the differences.

Ford has made some duel fuel and FFV vehicles which can run on Methanol blends. There is a refractometer in the fuel line which calculates the alcohol content and adjusts the fuel injection parameters to compensate.

I remember Ford made a special supercharged Cobra that ran on M-85 or Gas. This was a showcase for the FFV program, The car had two sets of injectors, and I belive an adjustable boost pressure gate. When the 85% methanol blend was used both sets of injectors were used and the car produced the most horses, as the gas level rose, the second bank of injectors were shut off and the boost was lowered.

My point was adding oxygenated additives to fuel is a political decision and does not make real good sense.

Some food for thought!
