mpg on brand new 2010 f250

[dabears5021]

just bought the truck with 36 miles on it about a month ago. the mpg started at 3.6 and now at 2k miles it is up to 10.6. is it still suppose to go up or what it seems to have slowed down?

Thanks

and i have been nice on the acceleration pedal

I guess it depends on if that is hwy or city u have been driving. I get around that when i stay around town a lot but 4 hwy mine goes up a little to 13.5 or 14 if im lucky. I do have around 1000 lbs extra weight w my toolboxes so that hurts me some. If u dont have much weight in urs i would excpect urs to get at least what mine does maybe even better. i do have my dpf deleted and a programmer on mine which helps very little on mileage 4 me but helps a ton on power. these trucks run good stock but they really run good w a programmer.

So how do I tune it without voiding my warranty?

that my friend is a "catch 22".....if u need warranty work....u would need to put old pipe back on and tune to stock......depends on your dealer.....i just flat out asked mine... he said...if it has nothing to do with the work being done then no problem...ie fix heated seat,

yup what he said, if you got issues and need to take it in, just spend the afternoon returning truck to complete stock re tune when you are done

ONE MORE THING..............after tuning my truck and driving it around.............i wouldn't think twice about having to spend a little time turning it back to stock for warranty work, as long as i can tune it back.......its one hell of an upgrade....i could never go back to driving it stock....NEVER

For what it is worth, I just purchased a 2010 F-350 CC LB with 13K miles and 360 hrs on the clock. I immediately added Diesel Kleene on my first tank. Computer said 16.5 and hand calculated I got 16.3 (391 miles at 24 gallons). This was on about a 50/50 hwy - city. Can't wait for a long road trip to get true hwy mpg. Maybe it break in a bit more for better numbers. i plan on experimenting with FPPF and Opti-Lube to see any improvements.

I purchased the 100K warrantee coverring 100% with a $100 deductable. With mpg's like this I won't be tuning the truck anytime soon. These truck got a bad wrap on the mggs. I kind look at it that 16 or better for a 7500# + truck is acceptable. I must admit I constantly watch the boost and rpm. In addition, I am king of light on the pedal with the exception of an occasional Duramax or Cummins on my right.

Absolutely love this truck!

Its slowed down b/c the mpg it shows in the dash is the cumulative since the last time it was reset.....your just adding more and more miles to the average. Hold down the reset button and start over and see what it starts at. SHould read in the 11-13 range in short time.
