Is this as good as it gets?

Okay guys,

I'm the new guy with the stupid questions...I have searched all over this forum and a couple of others trying to find the answer to my question. I have found hundreds of threads about the same topic but none that answer my question specifically. So, hopefully someone here can help....

I just bought a 2010 F250 Lariat one week ago yesterday. I have put just over 200 miles on it and the little thing on the dash is telling me that I am averaging 10.3mpg! Holy Crap....that sucks Is this the best I can expect? Is the computer wrong? Will it get better as it breaks in? WTH is going on??

this isnt surprising.. dpf delete and some spartan tuning and you'd be much better off.

X2....the regeneration eats up a lot of fuel. I wouldn't trust the lie-o-meter though. Hand calc is always best

Yes MPG suck with these trucks, only way to boost mpg and prolong the life of the motor is to tune and delete all the emissions crap off.

Agree with all the above comments - Lie-O-meter sucks - Don't pay any attention to it..

1 thing to do, is reset the average, no telling how long it sat on the dealer lots while idling. Don't trust the lie-o-meter, but a bunch of idling will drag the average down.

I drive a around 60 miles a day - city & interstate (which can become a parking lot) and mine is always in the 13.6 to 14.0 range - I have seen it get better and worse when doing the math.

I really appreciate the info guys...I'm pulling a trailer up north tomorrow, before I go I'll fill the tank, reset the meter and also hand calc the MPG and see what happens.

I'm not sure I'm ready yet for deleting a dpf (I don't even know what in the hell it is) or spending the $$$ for a programmer. But I'm sure these things will happen soon enough

I'm one of the lucky ones. I drive 40 miles each way to and from work. City, highway and back roads. I get 16.8 mpg. When I drive all highway I get 18-20 mpg, recently it was over 20 on the highway..I think it was a fluke. Mine regens every 400-450 miles. I baby it too! Hopefully yours gets better

We get 9Highway in our 6.4l.. So don't complain. lol

Once they get some more miles on them they seem to do a little better.

I remember talking to a guy who bought an 08 a few years back, I think it was at 15k he said the mileage jumped up 2 mpg.
