[Ecoboost MPG FWD vs AWD]

Just wanting to see what the real world comparison is of the FWD vs AWD ecoboost cars are over the long haul.  Someone that has owned their car for a year or so.  Mostly looking for highway as I don't do too much intown....mostly interstate travel.  

Thanks!

Hello from Flagstaff AZ.  Just picked up a 1996 Bronco from the original owner.  Needs some love but a good starting point.  Just looking for resources and general info.  Thanks!
