Yep, I am not interested in the government anywhere near the fuel I use. Butane, ethanol, or any of a dozen different things that get regulated into fuel. Government did nothing regarding an ethanol mandate prior to the late 80's / early 90's, and it did just fine. Many folks bought E10 willingly. I buy E15 now because it offers the lowest cost per mile for me to use, and there is no government mandate for E15. Sometimes E85 offers me the best value when the price spreads are better, and it doesn't have a government mandate either. I buy E15, E20, E30, or E85 freely based on pricing spreads and the fuel mileage I get from each fuel. When gasoline was higher a couple of years ago, my pickup got E85 for over 6 months.
Another reason I don't want government anywhere near my fuel. I pay more if fuel tax alone each year than many people pay in income and social security tax in a year. I pay nearly $11,000 a year just in fuel tax.
I realize that some don't put a lot of thought into what they put in their tank. If they did, many with flex fuel vehicles would figure out what gives them the best bang for the buck and probably buy higher blends of ethanol. Most of the folks that have a fit with ethanol are not most of the people out in the real world. Long before E10 was mandated for use in some areas, folks were buying E10 willingly because of the lower cost. E10 or any other blend, or any government mandate regarding ethanol doesn't even generate a blip on the radar of normal day to day discussions among most folks.
But it still remains... why would I want to use a non ethanol fuel that costs me 15.7 cents a mile to use when I can get E15 that costs me 13.1 cents a mile to use? That would be stupid. I don't have an irrational paranoia that would cause me to pay more per mile to operate my vehicle. Just one of those folks that does not suffer from an enlarged paranoia gland. So for some of us, ethanol is a very viable primary fuel and not just a novelty. If the price spreads were right, and the government did not mandate that ethanol be denatured with gasoline, I would use 100% ethanol. If the price spreads were such that ethanol free gas offered the best value, then I would use that. No bias one way or the other.
