I'm looking into getting an 08 F-250, but I'm not sure what Engine-Transmission-Rear Axle Ratio to get: 5.4L V-8 Gas-5 speed Auto Transmission-3.73/4.10, 6.8L V-10 Gas-5 speed Auto Transmission-4.10/4.30, 6.4L V-8 Diesel-5 speed Auto Transmission-3.55/3.73. What will give me better MPGs?

You need to decided what your hauling then decide on trans. my '08 250 gets 15-16 mpg it's a 373 rear. and I haul nothing. If your huling heavy stuff you need the appropriate rear. Diesel will give you the best mpg but reg. gas is cheaper. So you'll have to do the math and decide, Sorry, but good luck! I love my truck other than the diesel price.

Lucky you. I just got through with a 2600 mile round trip with my '08 F350. With only 16K miles on it, it broke down in Pilot Point Texas. Fuel injector stuck open, push rod bent and booster sensor blown - 3 days later and only 8mpg pulling a very light load. I drove 70mph trying to improve mile but no use - The 350 super duty is a dog with no power and crappy gas milage

I hate that you are having problems with your 350. My 250 continues to give me great service. I took it to the dealer saturday for its 30000 mile service and then the wife and I headed up the blue ridge parkway toward mt mitchell to see the fall colors. 290 mile trip averaged 15.5 mpg. Back in august we took the camper down to the outer banks. If I held it down between 60 and 65 I got about 10 mpg. However on one stretch lets say I was in a hurry to get the beach. Averaging about 80 to 85 mph mileage dropped to about 7mpg. Camper weighs about 9000 lbs empty is 35 feet long and 11 1/2 feet high. I easley had another 2000 lbs in cargo and passengers. At 85 mph truck had power to spare. Needless to say I'm still very happy with mine. I still average around 14 mpg in my day to day driving. I hope you can get the problems with your truck resolved. You might try to have the dealer re flash the main computer. It controls the fuel and air ratios and that has a lot to do with power and mileage. Good Luck

Has anyone tried removing the Dpf, Cat, exhaust and egrs yet? I have heard it is possible with the help of by-pass modules. just want to know what the results were. yes i know the warranty would be gone.

I have a 2008 6.4 ltr.F-250 super duty with about 3000 miles on the trk, and at best I am getting around 10-12 avg. MPG is this what I should expect to be the normal for this or will it get better and what could I possibly do to improve the mpg short of getting rid of the truck. I absolutely love the trk other than this.
Very concerned F-250 owner

I have an 08 f350 crew 4wd, srw. Bought new mileage sucked like yours. It's been getting better the longer I have the truck. now at 36,000 I'm getting 16-17 freeway empty at 70mph 10-11 towing a trailer weighing approx 8,000. around town 12-15 love the truck but have used a lot of fuel to get to where I am now

Your mileage should continue to improve. I have a friend who has a 250 just like mind except color who was only getting about 11mpg at first. He said at about 50 thousand his made a drastic improvement in mileage. At 32000 my latest trip gave me 19.2 on one stretch of interstate driving. This was pure interstate with cruse set on 65. For the whole trip I averaged 17.8mpg. This was blue ridge parkway starting at virginia state line to Ronoke and then interstate back home to Rock Hill SC, Truck continues to give me flawless service.
