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. ...

Turtle n Peeps,
Have to disagree with you. On all of our vehicles, I've noticed about a 10% decrease in real world mpg.
On one trip down south in the motorhome, I didn't realize I had filled up with real gas down south. I thought everything was E10 like good ol' New England. Anyway, shortly after we hit the road, I noticed the instantaneous mpg readout on my scan gauge was dancing around 7.9 mpg. Usually, on the ethanol junk, it had been around 7.1. The average MPG displays were up by a similar amount. I thought...hmmmmm...must be going down hill, though I didn't detect and incline. Looked at the altitude reading on the GPS, and we were actually very slightly increasing altitude.
When we first got the motorhome, it was averaging about high 7's to low 8's for mpg. Once the E10 became all we could get, that range dropped to high 6's to low 7's.
I know what the math numbers (and the government) say, but every one of my vehicles disagrees with those numbers. A 10% decrease is what I observe.
What you said about the water in the tank is true. Here, up north, in the winter months, we would add some "Dry Gas" (alcohol) to the tank periodically so that any water in the fuel tank would be absorbed and burned. Water in the fuel line could freeze, block the flow of gas and that's where you'd stay until it thawed out. In my opinion, the ONLY benefit of E10 is that Dry Gas is no longer needed. Funny thing, though, the auto stores still sell it! LOL
Sure wish we could get real gas again.
