I just bought a 2007 5.4 L 4X4 and it only had 4 miles on it when i picked it up. The thing is awsome, i love it, but it sure as hell aint getting the mileage it should be.I have asked around and some people are telling me that the first 400-800 miles are usually the worst on gas for a vehicle, mainly because the engine has to set itself and become programmed to your driving style etc... right now im basicly getting only 10 mpg city, and thats if i drive the thing like an old man. but i have only put about 130 miles on it. Is this normal or should i be going back to the dealer and asking for them to look at the computer or something?

If this is what i should expect then thats fine, but hey.. if this is not wright... plz let me know.


Thanks alot

Danny

 

Take it back to the dealer and keep takeing it back and complaining as long as its under warranty they might deny it but they can change chips to improve fuel milage I have frends that this has happened to

 

I just bought the same vehicle and just turned 1000 miles. I do drive like an old man and I am getting 17-18 MPG driving back and forth to work which is an 8 mile one way trip. It is a combination between city and highway.

 

There are also a few modifications you can make to help out on gaining MPG and a little HP. The stock air intake is one culpret. Check out some of the aftermarket air intake systems on the web. So far I have a throttle body spacer and a cold air intake system and noticed considerable HP response and better gas mileage (approx. 2-3 MPG).
