Lending support to the comment I made in the first paragraph is this story that Leanan just posted in Drumbeat:

Loss of fuel economy from ethanol-blended gasoline hits motorists in the wallet

The growing use of ethanol is making energy content more of an issue — particularly as record fuel prices crimp consumers.

The Energy Information Administration is keeping track of how ethanol is affecting average fuel economy in the United States. The federal agency projects that additional ethanol usage this year will cause average fuel economy to decline by an extra 0.5 percent.

So even if there was a 0.4% decrease in overall BTU usage, the total volume used would still increase.

I know by the math, 10% Ethanol does not sacrifice many BTU's, however, many people I talk to say they are losing 2-4 mpg since the 10% Ethanol came to market. Personally, my Subaru Outback went from 25mpg now to 22-23 and I've been slowing my highway speeds from a common 75 to keeping it under 70. That is a significant loss in efficiency from the 10% ethanol.
