Mostly correct information in here...except the one about it smelling like french fries...lol...obviously you've never actally run it and/or you are just making up stories. That one made me laugh.
Anyway, you guys are not correct when you say that if you feel a power increase it is because something is wrong with your vehicle. You can tune a vehicle for an type or octane of gas. Obviously it makes more sense to BUILD an engine for a specific fuel type/octane, but I'm pretty sure what GM did here was to include a tune for regular 87 octane, AND a tune for E85. When the fuel sensor tells the ECU it has E85 then it bumps timing to take some advantage of the higher octane fuel. Then the timing goes back down when you go back to E10 or whatever you have in your area. A modern engine is always going to be bumping timing as much as it can and using the knock sensor to say when enough is enough.
Another big advantage of an E85 capable vehicle (and disadvantage in older cars) is that the rubber hoses and plastic fittings are ethanol safe for E85, so we shouldn't have as many problems as older cars do. Since they were never designed for so much ethanol older fuel systems (especially in boats with fiberglass fuel cells) these systems are failing from the inside out. Not good at all.
This is all thanks to the govt. shoving this corn fuel down our throats. I'm totally onboard with keeping more work/money in the USA but we have a global economy now and this corn fuel sucks for 90% of the vehicles out there. Just because it is produced in America isn't a good thing. Buying a Toyota built in South Carolina isn't worse than buying a Ford built in Mexico now is it? Plus now that more farmers are growing corn because they make more money since it is highly subsidized our food prices are going up and we are going to have to import more from other coutries. WTF?
