Using ethanol free gas.
I have a 2014 Ram 3500 w/ 6.4 Hemi. I have been using the pure gas which is 100% ethanol Free. While it more $$ I get around 4MPG in the city and about 6 MPG on the highway, your mileage may vary. ...

Gas pumps are calibrated as to the volume dispensed. Colder gasoline has more energy than the warmer if of the same volume. No one is losing 10% in mileage by using an E10 gas blend. Phase separation is rare but storing 2 cycle mixed gas in extremely cold climes, using E10 gas, can cause issues.
We have had E10 in MN for years. It is pretty much a non-issue.
FWIW, for 6 years I maintained a fleet of small engine equipment that was fueled with E10 gas (125 engines). There was basically no fuel related problems with E10 gas. One exception was a line of small Kawasaki engines that had clogged main jets upon rollout in the Spring. I resolved that by draining the fuel system in those engines.
I have noticed that stored E10 gas is more prone to breakdown when in long term storage (> 6 mos.). This can be remedied by using fuel stabilizer or rotating gas supply more frequently.
I have no reason to doubt the OP's results but some of his mileage differences may be due to the intrinsic construction of the engine and it's fuel management accessories and not absolutely due to the addition of alcohol.
