  • Ethanol Will Become a Fad Without Government Intervention
    William, YES you are imagining the decrease in fuel efficiency, or maybe it was caused by other factors, like speed, more stops and starts, or A/C usage? Anyway, I can prove that the ethanol didn't cause the 5 mpg loss in fuel efficiency. First, you went from supposedly 100% gasoline to 90% gasoline and 10% ethanol. Even if you got NO energy out of the ethanol (which everyone can agree is not the case), the gas mileage could only drop 10% or 3.2 mpg to 28.8 mpg. Second, it is a proven fact that a gallon of ethanol has only 30% less energy than a gallon of gasoline, so in reality, given known figures for energy content, your mpg using 10% ethanol will only fall a miniscule 3%, which in your case is still just shy of 1 mpg. In the end, the mpg argument is a moot one when talking about which source is cleaner, and which one uses more energy because all of those analyses compare the two sources based on energy output, not gallons of fuel, thereby bypassing the need to correct for the discrepancy between the two fuels in energy density.
