Mileage on 07

[AStrand]

I have a 07 2500 with the 5. 9 in it. This weekend I took a trip to Fargo, ND. This was about a 340 mile trip. On the way up there I had about a 30 mph head wind. Driving 70 with interstate all the way. When I got up there I filled the truck and got 16. 5 mpg bucking the wind. When I drove home there was no head wind and filled it again and got 21. 2 mpg. These were both hand calc. I am really impressed with my truck. I have 4000 miles on it since I got in July.

I have found that if I drive at 1800 and 2000 rpm she seems to do the best. (sweet spot)

And it should get better as time goes by. Have the same year as you do with an auto and it gets great mileage on long trips, however; when pulling that 7000lb TT behind it, it does tend to drop just a tad. But wouldn't own another truck after getting this one.

Mine has an overall average of 17. 4 mpg for the first 25,000 miles. That includes some towing of a 20' skiff with T-top. The T-top creates a lot of windage and I get about 12-13 mpg towing it. My last 3 tanks have averaged 18. 5 mpg for general commuting. The best was 19. 6 mpg on a long trip from Raleigh, NC to Columbus, OH. I was hoping for 20 mpg, but didn't quite get it. Oh yeah, I only drive 65 mph.

On my trip home I started out driving 65mph for the first 100 miles at about 1700 rpm. The overhead showed 19. 6 mpg. I decided that I will try driving the speed limit (70). This was at 1950 rpm. The over head started moving up after a few miles. Finally after a couple of hours driving at that speed it showed 21 mpg. When I got home and filled it and hand calculted it, it came out to 21. 2.

Towing my 8000 lb 5th whl I have gotten 11 at the lowest and 13 for the best. I still really love these trucks and what they can do over a gas engine. I just wish the fuel prices were better.

Just turned 11k miles, last 7k miles continous hauling fixed load of 3000 lbs gravel for engine break-in. Hand calculated, 65 mph, 18. 2 mpg. I'm guessing empty truck should get to 21+ mpg.
