My New Ram 2500 6.4 MPG Update
Posting this because people ask about the mileage: First 300 miles: 12.2 mpg mixed driving. 2 days were in below zero weather and gas had 10% alcohol mixture.

Hmmm....20-21 would be highway? Not mixed? And it would NOT be in sub zero temperatures in Nevada with winter blended fuel. And you have considerably more than 300 miles on your truck on your 10 year old truck. As you did experience when you bought your truck, MPGs do improve as it breaks in.
Apparently you have never been to Northern Nevada in the winter! You mentioned the below zero temps, and the winter blend, but forgot the wind. The great American author, Mark Twain, described in his book Roughing It the Washoe Zephyrs, very strong winds that occur in Washoe Valley that is five miles from my home. Stong winds have a drastic effect on mileage especially a head wind. As to my first 300 miles on my new 2005 truck back in 2005, it was from Reno to Sacramento and back, half on the Interstate Route system; over two passes, the lowest at 7300 feet, the highest at 8500 feet. And yea, it got good mileage. And as I posted earlier the diesel broke in at around 35,000 miles and then again at around 85,000 miles with slightly better mileage numbers.
Anybody that spends time on the TDR website knows that the '05 Rams got very good mileage, mileage became less with later models mostly due to environmental issues and more power increases. The 6.7 has more power; the 5.9 gets better mileage. That is fact, not exaggeration!
