Found this on WIKI:  Ethanol is most commonly used to power automobiles, though it may be used to power other vehicles, such as farm tractors, boats and airplanes. Ethanol (E100) consumption in an engine is approximately 51% higher than for gasoline since the energy per unit volume of ethanol is 34% lower than for gasoline.^[26][27] The higher compression ratios in an ethanol-only engine allow for increased power output and better fuel economy than could be obtained with lower compression ratios.^[28][29] In general, ethanol-only engines are tuned to give slightly better power and torque output than gasoline-powered engines. In flexible fuel vehicles, the lower compression ratio requires tunings that give the same output when using either gasoline or hydrated ethanol. For maximum use of ethanol's benefits, a much higher compression ratio should be used.^[30] Current high compression neat ethanol engine designs are approximately 20 to 30% more fuel efficient than their gasoline-only counterparts.^[31]

As for my feeling on it, when we lived in the tent and it was 19 degrees F. outside, we would burn alcohol for heat.  The higher the %, the more suet it produced. That was my observation anyhow…….

   We use a lot of ethanol in the US…….

It killed two catalytic converters on my 4wd which cost a packet. my mechanic told me that it creates so much work for them and warned me to avoid it, it also evaporates very readily so any savings made at the bowser does the same.

I thought I heard that it would be cheaper than gasoline. Why can't they just run cars on Hydrogen ? what about the electric cars ?

What a waste of perfectly edible corn. Capitalism at its worst.
