Hi, new to forum, but had a question on MPG. I recently purchased a 2012 Ram 1500 Laramie with the 3:92 and 5.7 HEMI. I have a 60-40 mixed highway/city driving (about 20 miles/day) but haven't been able to crack 13.5 mpg. Recent 350 mile round trip only averaged 14.4 at about 70 miles per hour. I am pretty easy on the throttle (unlike my leadfoot wife!). Not sure if I just need to break it in, cold winter weather, or E10 fuel that could be impacting it. We live in Iowa so it is generally pretty flat. This isn't my first truck so I wasn't expecting outstanding, but just a little disappointed. I have seen a lot of posts with much better fuel economy numbers. Any suggestions?
