unsure about 6.7L cummins
Hey I am looking to buy a 2010 2500 with a 6.7 but I am unsure about the mileage. I absolutely love the truck and would like to get 18+ mpg 20+ would be better. What I can do to improve the mileage. I am running a F-250 5.4l right now and hate the truck it is mechanically sound but ride terrible and only get 6.5-7.5 mpg pulling my holiday trailer. Any input on the 6.7 mileage and any improvents that i could make without voiding the warrantee would be great

I just drove my 2010 2500 megacab 4x4 6.7 w/ 6 speed 400 miles one way to new orleans thursday. At an average speed of 74 mph there it got right at 17 mpg. On the way back I ran close to 78 mph average but up to about 90 at times at average 16 mph. Not bad with only having 2600 miles on the truck now and also 3.73 gears. Haven't pulled anything long term yet so cannot discuss pulling fuel mileage.

Had a 08 mega cab (4wd) with 6.7 and I averaged 15-18.5 mpg driving 75 to 83 mph on mostly less than flat terrain. When pulling a trailer averaged between 10-13 mpg depending on terrain and speed. Fuel mileage range came after installing cold air intake (Cai), cat back exhaust, and tuner. Cai or cat back doesn't have to be bought at dealership as they are still required to cover truck under bumper to bumper warranty or engine warranty so long as it's not an issue caused by aftermarket product. My tuner I always reset to stock when bringing into dealership for work.
