I am glad ethanol if readily available. Due to the low pricing, my 2015 Chevy 2500 6.0 has been on E85 exclusively for almost 2 years.
I filled up the other day for $1.12 a gallon. It got as low as $.99 for a couple of weeks. Murphy station in Newton, Iowa. Pump price with no discount.
My 2500 averages about 10 mpg on the stuff. So right now the cost per mile is 11 cents a mile. For my 3/4 ton pickup to get 11 cent per mile fuel cost using regular non ethanol gas, it would have to average almost 21 mpg. That is not ever going to happen. Even on E10, it would have to average 19 mpg to get 11 cents per mile fuel cost. Again, not going to happen. A Diesel 3/4 ton would have to average almost 26 mpg for all miles to get 11 cents per mile fuel cost. Again, not going to happen anytime soon.
Been using various blends of ethanol since it started being available in the late 70's. My 1974 Pontiac used E10 all the time after it started being at the pumps. Car had 250,000 miles on it when it died of body cancer. Motor was still good. No carburetor or fuel system problems.
I am an advocate of letting people choose if they want to or don't want to use the stuff as they see fit.
