Gentlemen,
I am the biggest independent retailer of E-85 in Arizona. That isn't saying much as I only sell about 25,000 gallons a month. Arizona law mandates that taxi cabs servicing the Phoenix International Airport use alternative fuels and for most of them that means E-85. The cab drivers hate it and report a 25 to 30% drop in fuel mileage which makes sense as Ethanol only has 65% as much energy per gallon as gasoline. Though it is low on energy content, it doesn't detonate easily so it's octane is very high (about 120 I believe). So to make big power with it you need monster fuel pumps and injectors to flow large volumes of that swill. E-85 is highly corrosive and so I must use all stainless steel pumps, impellers, piping, and nozzles. It also, unlike gasoline, soaks up water like a sponge. Condensation will sit on the bottom of my gasoline tanks (below the fuel pickup going to the pumps) and from time to time I have it removed. Condensation mixes with Ethanol and dilutes that fuel.
It takes hundreds of gallons of water and almost a gallon of diesel (farming) to produce a gallon of low energy, highly corrosive, lousy fuel mileage Ethanol. It's good for my station but it's bad for our country and the sooner that all subsidies and mandates go away, the better. Like the solar industry (my canopies are covered with tax payer subsidized solar panels too), without mandates and subsidies, Ethanol is DEAD.
