I got my 2010 5.7L HEMI Crew Cab on May 17th of 2011. To date she has 11,550 miles:
Average 11.53mpg. However, I really
like to step into the HEMI quite often so I'm probably not the best guy to be posting about this come to think of it! lol
I have gotten 15.49mpg when I was "taking it easy" (due to a ticket - D'oh!)
I have only taken one trip so far so there's no average for that. But on that trip we got 19.637mpg and had a 10-20mph head-wind about half the way. SO I have no idea why I even brought it up. I'll shut up now!
