#129 of 133 Bad fuel mpg by nme1
Feb 09, 2010 (9:43 pm)
We have a 2008 F250 Diesel with 51,000 miles and are still get terrible fuel mileage. It averages between 11 -12 and thats with a chip. We are thinking about changing rear ends (now has 3.73) . Has anyone ever done this and improved their fuel mileage?

My understanding is that changing to a 4.10 rear end will further decrease your mileage. I was under the impression that the 2008 change in the engine and exhaust system to lessen the emissions was the problem.

can't remember my gear ratio but it's higher, highway gears, I wish I had 3:73's. I mostly city drive with a moderate load on and I'm only getting 10 mpg. Empty with a family traveling I think I was getting about 12mpg

Purchased an F-250 super duty and have been averaging 9-12 MPG around town driving the posted speed limit. Will tow my 4,000 Lb boat this weekend for the first time and I'm concerned about the millage I will get. I understand installing a chip only has minor benefits to the fuel economy but I'm willing to try it. Any recommendations on what brand/chip/programer to go with to increase efficiency?Thanks for any advice

How did things work out with your planned upgrades?
