Hello.

The cluster guage mileage report is fair at best. Generally correct but the margin is wide.

Best to hand caculate the mileage. My cluster reads 12-16mpg, hand calc'd its 15.39.

Fill out your signature so folks know what kind of setup you're running. Stock tires sizes I assume? How much mileage?

get yourself a full turbo back 4" exhaust, a set of gauges, then go with an SCT tuner and turn it up! My '06 F250 has got just about 20k on the clock and I'm seeing 17-18mpg regularly just normal driving, some city but mostly highway. My race file gives me about 2 more mpg than stock programming. Also when was the last time you changed your fuel filters? If you're running ULSD fuel like most everybody else try using a shot of powerservice diesel kleen or whatever additive you choose. With diesel kleen I saw about a 1 mpg increase as well.

fuel filters should be changed every 15 to 20k.. As to the gearing it should be listed on the build tag on your drivers door sill
