so my dad has a 2004 f-150 with a 5.4 4x4 automatic, and he only gets 12mpg at best. since im getting my licence soon and am going to be using that truck alot, i was wonderin if there are anyways to get better gas milage out of it, cause im in high school and id rather spend my moneyy restoring my 56' f100
so any ideas?

thanks- charlie

 

get a tuner and dont drive it like you stole it.

 

running oversized tires?..ethanol gas?..12 in pretty low. Start with a tune up..plugs fuel filter, air filter, clean MAF..check tire pressure, any brakes dragging? driving it like you stole it?. alot of stop & go driving?

 

12mpg is what you're going to get in mixed city/hwy driving (60/40) with 10% ETOH gas. You will get 13-14 with standard gas. Don't waste your money attempting to put intakes, exhausts or tuners if you're looking to improve that number. Those mods will make it sound real nice and wake up the engine, but 12mpg using 10% ETOH gas is as good as it gets. The only thing that helps is to drive like there's a raw egg taped to the gas pedal...push lightly and you won't crack it.

 

Welcome to the world of a FORD truck with a 5.4, an automatic & 4X4!
Thats about as good as it gets. But as said above, do a total tune up & drive like your Grandma.
Good luck on the 56, and lets see some pic's!

 

Pretty accurate. I've had mine since new and back when gas was 100% gas, I got 13-14 in normal all around running and 18-19 on the interstate. Ethanol cuts a mile or two off my all around and I haven't been on any long trips with ethanol.

 

as said before making it shift below/around 2k rpm really makes a difference, if you drive it like a truck you should pick up a few mpg's.

 

I have been getting 12.8 with a 6" lift, oversized tires, 4X4, evolution chip, supreme gasoline, and mostly city driving. I definitely would be light on the gas pedal if you are really looking to save money on gas though.

 

ok thanks ill just do a tune up for now
and im getting the 56 dissasembled ill get som epics up soon but something cool to know, lol i just found out someone put a pintiac 389 from an old gto in it )

 

My '05 is still bone stock. I get 13~14 around town, hand-calculated, 16~17 tops on all-freeway running no faster than 70mph. My wife has a heavy foot when accelerating and braking and gets at best 13mpg around town when she drives it. She complains I drive like a grandpa

One thing I've noticed is brand new tires tend to result in lousier mpg's. It gets better as they wear down.

 

Ive got a 2004 with the 4.6 and i do about 60% highway, 40% city and the last tank i got 17.8 mpg on regular gas that has 10% ethanol. But my Edge only shows around 15 mpg.

 

07 Scab Heavy Half, long bed, 5.4 with 4.10 gearing and it virgin except for Alloy rims. I get around 15 mpg in town and 18+mpg highway. On the highway, I keep the rpms at 2k to get best mileage. Around town I'm another one of the Grandpa drivers (actually I am a Grandpa). I also plan trips etc so I'm not doing any more driving than I have to.

I'm also a stickler for maintenance and keeping everything current.

get a job! I'm in high school and get 10-11 mpg (big tires, bad driving (for fuel economy)) all you have to do is work 6-7 days a week and that $70.00 worth of gas every week will feel like nothing... (not really )

 

Ouch this is just mean man. What high school kid wants to work the entire week they want to go out with friends and have a good time.

 

I'm an adult and don't want to work the whole week
