I am looking to order a 2008 F250. Does anyone have any experience with gas mileage on 5.4L with 4.10 Axle Ratio vs a 6.8L V10 4.10 Axle ratio.
I wouldn't normally be too concered except with what the price of gas is doing now days I need to watch my pennies.

 

I have been getting about 13 - 14 around town and depending on how you drive 16-20 on hwy. To consistantly get 18 - 20 on hwy you have to drive like there is an egg under the gas peddle. 5.4 w/ 4:10

 

Thanks for your input it will help make my decision.
