I wanted to drop a line and say thanks as this is terrific information. I only wish the local fuel stations would sell anything ethanol (other than Casey's General Stores 10% blend).

Your research showed exactly what I found out a few years ago - that vehicles run poorly on a 10% ethanol mix. I found out the hard way that the fuel was 10% ethanol in the first place (didn't notice the sticker on the pump) - my Toyota 4x4 ran like it was ingesting wet gas (fuel with some water content). It took all kinds of additives off the shelf (octane booster, heet, etc.) to get the poor little 2.4L EFI motor to suck that stuff even partially through. Once it got 1/4 tank down, I topped off with Super Unleaded (93 octane out here) and it started improving. Turns out that my 3,800 pound 4 cylinder truck really did need all of it's available power to climb the hills out here.

I'm going to keep my eyes open in the near future for E85 and hope for the best. In the meantime, I hope they find a more suitable source than edible corn to produce fuel. Imagine the backwards world we live in - with people starving with little food in some areas - and the rest of us wanting to turn food into fuel for our vehicles.
