Ram 2500 5.7 hemi mpg.....a bit disappointed
The other day we took a trip ftom southern illinois, through st louis, to southern Missouri...a couple of hundred miles each way. Starting out I reset the mpg meter on the dash, and recorded 17.4-1...

Yep, cold, wind, speed. That sounds line line with what HD trucks should get. We drove our 2011 Suburban 6.0L over 2600 miles Detroit to Orlando and back in February 2012 starting at 6k miles on the engine. We averaged 16mpg down and 14mpg up. Another trip we got 17.7mpg over 1000 miles, September, 20k miles. Both trips were cruising at 75-80mph. Another 1800 mile trip in December was 15mpg again.
