Well, the contour is back to normal fuel now. The car performes better again and maybe the alcohol fixed my ineffiecent catalytic converter...because i have not got a check engine code in over 500 miles, which is rare. Usually every 100 miles the light will come on. the fuel was determined to cost a little more because of the lower energy content. So my test is complete.
My Dad talked to one of their automotive engineers at work on the subject as well and the guy has a new Suburban and thats built for E85 and he ran a tank of E85 and noticed poor fuel economy as compared to regular gasoline too. He did not think the E85 would hurt the car, but it didn;t help it. I would benefit from different temp spark plugs and more compression, but this is the extent of my test for now.
