SOMETHING WRONG???? HELP
Ive Got a 01 250 SD with the 5.4 and 3.73 gears! I know the gears are part of the problem but Im getting horrible gas milage compared to some of the other posts on gas milage I have read. Im getting about 8 at best and that is with out towing anything, and it seems as if the horse power just isnt there, very sluggish. I cant find anything wrong though, no odd sounds, nothing looks out of place, it doesnt miss, and runs fairly smooth. Heres a for instance, on my way to work there is this slow grade hill probably no more than 15deg. It runs about 1/4 to the top but I lose probably 10 to 15 mph! To me that doesnt seem right. Is it me or should I take it in and have it looked over? Please help I love this truck but the power is killing me!! HELP

SOMETHING WRONG???? HELP
Well, Like I said in another post, I get best of 14 (13 seems the norm)on the highway and thats running 35" tires. I do however have a cat back, KN FIPK, and a chip, but I don't think that would be the difference.
I drive to my cottage a lot during the summer, it's a bit hilly, and other than comming out of OD, my truck holds it own, actually I always think to myself how good it is compared to my other fords that Iv'e had. I only have 9,000 miles on mine but that shouldn't matter either.
You might want to have the dealer read you computer to see if something is wron, 8mpg, just sounds wrong.

8MPG sounds awful low.... hmmmmm.
How many miles are on your truck?
Better start with the basics, maybe you'll find something amiss:
- have dealer (or other auto shop) hook it up to an engine computer
and make sure all plugs are firing well and there are no bad ignition coils
- excessively dirty air filter?
- plugged/dirty fuel filter?
- cat converter starting to get plugged up?
All these things can affect MPG.
That's all I can think of for now (have not had my AM coffee yet).
Good luck!

Thats bad !
All of the above suggestions are right on !
Is that 3.03 gears or 3.73 gears when you guys put the smiley in there it confuses me ,but they did not put 303 in a duty that i know of.
If it is a 4x4 and esof make sure its not stuck in 4x4 with a bad indicator light. seen it happen on explorers.
clogged cats will cause problems like this as stated.collapsed exhaust pipes or bad o2 sensors
have you been switching gas octanes? these trucks are setup to run 87, unless you have a chip.
you really haven't given us much info on your truck ? any mods ?

The gears are not the problem. I don't think you will get much better
than your 3.73.

living in alaska ,doesn't really help your mileage either !
being that cold ,a crewcab also ! but still thats low mileage!
I would be take it back in to the dealer.sometime it takes the pcm to learn its program,maybe the air temps are not helping either.

Rich brings up a good point: maybe it's somewhat related to the colder
temps and higher altitude. Not sure about the latter (maybe Anchorage is
not that high up...), but it made me think.
Another thought: do you think you got some bad gas at one time or
another? I mean, maybe an injector or three are a little clogged.
Maybe a cheap test would be to run some fuel cleaner thru the tank
once or twice to see if that helps out.
I agree with everyone else that at that low a mileage, you need to take
the truck back to the dealer and complain loudly.
8MPG is way too low.

FWIW, I've got the same setup on my 01 SD with 37K miles, run 87 octane, commute 80 miles a day in heavy, slow highway traffic five days a week and drive all over the Texas Hill Country on weekends, and my computer says I average a steady 14.7 mpg, day-in and day-out. About the worst I've seen is a brief dip down in the 10-11 mpg range when pulling a trailer up a hill. This drive train has proven to be the perfect choice for my commuting and weekend needs.
I can only repeat what others have advised: go back to the dealer and complain long and loudly!

Go to the dealer man, I get 11 and 12 on my 99 V10 with 4.30 gear, @55 to 70 mph, and 8 to 10 pulling my 6,000 trailer @ 65 to 70 mph.
go back and talk to the and let us know.
