Running ethanol free gas, I had gotten close to 30mpg average with a 2010 Ram 1500 (with the multi-displacement 5.7L Hemi and most fuel efficient axle ratio) on a tank or two during trips from Alabama to Minnesota.F-series I presume? That's would be good mileage for a small truck, let alone a full-size!
However, normal commute driving for me (mostly highway) was usually mid-20's on ethanol-free gasoline and a bit lower on gas that may have been up to 15% ethanol.
Recently I've heard that some of the newer 3/4 ton trucks may even be getting up to high 20s/low 30's when running empty..... haven't seen it myself yet, but I wouldn't be surprised given some of the 1//2 ton trucks have been getting into that fuel economy range in the last few years.
It's pretty amazing what has been happening with engines in the last few years..... all those electronics in modern engines are really working to squeeze the energy out of every last drop of fuel.
