Sometimes I get bad gas, sometimes I get good gas. With a barrel of oil being so cheap, it it going to make adding ethanol to gasoline a cost prohibitive idea with so much surplus gasoline availa...

And there is a fact that alcohol contains less energy per gallon that gasoline so your MPG suffers with Alcohol. Without double checking the research (Which I do not feel like doing just now) I believe EtOH is about 10 percent less powerful, so E-10 should cost you 1% in MPG. That said I have seen much greater claims.
I think your math is a little off there friend.
Even the US Dept. of Energy website says; "Since ethanol contains about two-thirds as much energy as gasoline, vehicles will typically go 3% to 4% fewer miles per gallon on E10 and 4% to 5% fewer on E15 than on 100% gasoline." and you have to believe they're being very optimistic and using mathematical calculations and not real world figures.
In a study done by Edmunds they tested a 2007 Chevy Tahoe, an E85 Flex-fuel ready vehicle, in a 'real world' controlled mileage test. The results? Mileage dropped 26% while burning E85 fuel.
Yes E85 is not worth it when you check mileage but you also have to go out of your way to get it,I tried it once in my 6.2 pulling the trailer and will never use it agian. I use E10 98% of the time but I have used regular gas and I can say with real world experience pulling the trailer makes no difference in the mileage between the two. I have a aux tank so I get a large quantity of gas when we fuel up so I would have noticed the difference, with the instant mpg feature on our Ford it's easy to check the differences between tanks.
