Interesting, well I dont doubt it honestly. Back when E85 just started becoming popular some of the local gas stations were selling E85 w/ 75-80% ethanol while marking up the price like crazy...in some cases $.60 or more and this was during the summer months when we typically have good quality ethanol.
Like you said 100 octane is $10/gal so sometimes we just have to deal with it...I haven't used E85 in about 3 years now and I miss that smell of warming my car up in the morning
