Mileage of 6.4 Hemi

I like that my 2015 Chevy 2500 6.0 is flex fuel. On E85 I generally have averaged around 11 mpg for all miles, with 13-14 on road trips and in the 8 mpg range towing. That doesn't sound great, but when E85 is so cheap, even with the lower mpg I still spend way less per mile on fuel than using regular, E10, or even if I had a diesel in the pickup. I filled Friday with E85 and it was $1.53 a gallon. The pickup has been on a study diet of E85 for well over a year now. Even a 2000 mile round trip to Wyoming last August, used E85 the entire trip. Actually, it did better t higher elevations than I thought it would. Could be the higher oxygen content of Ethanol. Sounds good anyway.
