Can anyone tell me if this is normal? I just got my 2011 F-250 XLT FX4 Crew Cab short bed a couple weeks ago and the fuel economy seems very erratic. It varies on the same road, same conditions from 12-13 MPG to 24-25 MPG. I drive about 50 miles each way to work and for about half the trip if will get 12-13 and the other half I will get 24-25. it is completely flat terrain (East Arkansas). There doesnt seem to be any consistant pattern. It behaves this way every day, not just during a regen.
