I know I bought a Truck, and I know backing off the pedal will better my mileage. For those that have had a REAL problem, has anyone
been satisfied with a fuel economy increase by repair? 11.6 mpg is not good in my book. I have had the truck in the shop twice and they keep telling me my truck is "in spec". Pretty broad "spec" if you ask me. I would like to crawl from bottom spec to the spec summit if you know what I mean. Anyone tell me if they had satisfactory repairs, and how they obtained them?

 

All I know is that is NOT normal, you should be getting around 14 city and about 18 highway. Unless you drive like a mad man and 11mpg would make sence. If I were you, I'd take it to another Ford Dealer and see what they can do for you, 11mpg just doesn't sound right and I drive my truck very hard and I still do better on gass then you do. Goodluck!!

 

just curious are you running 5w20 oil and is your air filter clean

 

At 6100 miles it has been serviced twice, oil filters...ect. All done by ford. I did have a rather exceptional tank last summer. 100% freeway on a whole tank reasonably driven = 14mpg.

 

I have 2,300 miles on mine (5.4, 3.55 rear) and I am only getting 13mpg tops. This is 40% city, 60% highway. If it doesn't get better by oil change time, I will ask about the reflash.

 

scab 4x4 5.4 3600 miles 11.5 mpg city and highway. I am always easy on the pedal... well most of the time.

 

Got about 1500 miles on an 05 Lariat and I'm getting about 15mpg. I drive about average, not a lead foot but not a ***** foot either. Seems about right to me.

 

I average just over 15mpg mixed city/fwy driving.

I keep a spreadsheet of my fuel economy. Here is a link if you're interested... http://users.adelphia.net/~bamorris2

 

At 3500 miles I've been averaging about 16 mpg over all the tankfuls. I had it serviced and they reflashed it. Might be another 1mpg better

 

how are your roads? hills will make your miliage drop like rocks. i do great when i drive in arizona but back home in san diego i can get 12 if i drive slooow. mines been steadily going up since i got over 10K on it now.

you can get lighter wheels, driveshafts, brake rotors etc.

 

First tank 14, second 16 (lots of highway) and last tank 15 or so. I have 2k miles. I am also running a diablo predator, which should increase MPG a bit, depending on how well I keep off the gas pedal!

 

04 scab 3.73 FX4 4X4 average 14.5 mpg 75% highway driving. For the most part not a lead foot. I sure would like to get 18 or so like some of you are getting.

 

I'm up pretty high..lotsa hills alla round us...

 

Hey bamorris22 , nice spreadsheet. You did a great job on keeping all your records. By the way, i think it's interesting how your mileage increased that much with an exhaust.

It seams to me that it is a combination of a lot of things that effects you mileage. A truck with exhaust, air filter, bed cover, supertunner, lower elevation, and a light foot will deffinatly get better milage than a city truck with a heavy foot and stock configuration at high altitude. I think that the data posted by bamorris22 is perfect for showing how it can help.

 

I don't see any significant increase after the exhaust was added.
