I ignored this statement the first time, however since you insist on repeating it I'll address it for what its worth. Your opinion. My opinion is your opinion is incorrect. However because it is your opinion I will not bash you for it. I will only try to provide evidence so you can rethink your position. Maybe you didn't have all the facts when you made your opinion, maybe you did? However, your first statement about financial interest do not add value to the conversation, instead all they do is stifle the conversation.
The original poster asked for information. Information was posted, and most of it was the usual uneducated crap. When someone with actual knowledge of the industry speaks up you try to shut them down, not once but twice, without facts. Do you want all information to make an educated opinion? Or just more information to justify your position on the subject?
I don't have any vested interest in ethanol per the definition posted earlier. However I work where millions (with an S) is spent every year testing engines, and I don't mean little engines, like in your truck. Mostly big diesel (bigger than a semi), however there are alternative fuels being tested as well, again in the millions of dollars per year. The companies interest lies in selling product. They will sell more product if their equipment works faster and harder while burning less fuel than the competition. I am also a mechanic, no longer by trade. In fact not more than two hours ago I finished a brake job for a family member. Last spring I did an engine swap for a low income family, my labor was free. She did make me some Christmas cookies during the holidays though. It was appreciated as much as she appreciated the work I did for her. I run a 1957 Johnson outboard on my 1967 Alumacraft boat. This is my daily fishing rig. My Johnson will never see ethanol, however all my other motors do. I have no problems. My Astro van had 286,000 miles on the original fuel filter. Yep ethanol since day one. I never replaced any engine parts, except for usual tune up items.
The mechanic repairing your fuel system/engine isn't about to tell you the reason for your problems is because you screwed up. How likely would you be to go back to him again? I will say it again, ethanol did not create the problem. The problem was already there, you just didn't know it yet.
Ethanol eats gaskets, seals, and hoses that are not designed for it. Poor design, or the engine wasn't built for ethanol. Owner should have known better. Operator error.
Gasoline leaves residue/deposits, ethanol cleans it out, fouling out the plugs or worse. Operator error.
As for subsidies, obviously you don't know that oil/gas is still being subsidized? Last year it was estimated at $37.5 billion (With a B).

I for one see no reason to subsidize the oil industry, however we still do it. Even when they are making record profits.
