Hello, i have just recently purchased a 2002 ford F150 4x4 sport w/ a 4 speed + overdrive manual transmission. it was used, and had 2600 miles on it. I was wondering what the average listed gas milage is for these trucks. i drive to work and back every day, a 60 mile round trip. i drive 70 mph the entire way. i average 10 mpg on the highway and in the city. i have the bed cover on correctly and am not too heavy on the accelerator. i purchased the 4.2 L because i thought that i would get fairly good milage, and from what i have read most people do. as far as i know, everything is stock. at 70Mph, i turn about 2300 Rpms. why is the gas milage so poor and what can i do to fix this problem.

 

Well, I'd say mine averages around 14 - 16 everywhere. I have a 2WD though. A 4x4 is going to get a little worse mileage I'd think, but 10 seems a bit low. As far as fixing it, you got me.

 

Wow ! 10 mpg is not right. I have a 4.2 / 5 speed / 2wd - all stock and get 22 mpg out on the highway and 19 around town.

I'd definitly get it checked over from the dealer since it is still under warranty.

 

10 is pretty bad, even my 347 stroker gets better gas mileage than that =). My 01 4.2 manual and 3.55 gears gets 20 consistantly. Try cleaning your MAF sensor wires, should pick up about 5 mpg at least if that's the problem. I once had a '96 Cougar that got 14 mpg, replaced the MAF sensor(before I knew you could clean the wires) and it got 24 mpg all the time, lol, sometimes it's just a simple little problem.

 

mine gets crappy mileage too dont feel bad, my boy has the 4.6L 8cyl and gets better mileage than me with the 5-speed v-sicks...grrrr im pissed that i got this pile now

 

well,
I have a 1998 f-150 2wd. I get about 14 miles to the gal. I am very heavy on the gas, and do alot of highway miles. I was hoping for better gas milage when I bought mine; if I had it to do over I would have gone with an 8cyl.

amen Rick. hindsight is 20/20

 

I know how to fix your problem. I have a 99 xl 4x4 4.2, mine was hard on fuel first when I got it, the problem was a bad mass air flow sensor, the one in your air intake, looks like a needle, positioned vertically in the tube. These sometimes malfunction and you will know it, your mileage goes down considerably. ford taurus, also has this as a common problem.

 

Now there's a good tip. "check the MAF" I have also been dis'ed by my poor Milage. Bought this truck with 30,000 mi on it and extected 17 plus with stock tires and 3:55 rear. Best yet is 15.5 with hwy/fwy 30 miles ea way. Put in new Platium 2 plugs and an AirRaid air filter better power but milage unchanged. ok a little heavy footed.

I just got a 2001 2wd and on my first tank I got about 12mpg. I admit I got on the gas a few times to test the power and I live in some hills. But 12 seemed a bit low to me since I we expecting 18city/20hwy.

 

like many others I too opted for the 4.2 thinking the mpg would be better than the V8.. not soo. I cant get any better than 14 to 15.5 new plugs,new wires and a k&n filter did not help make a difference either. I plan to try new cats and muffler next. sucks spending all this money just to try and save a few bucks a month on mileage.. oh well its only money...

 

Thats super crazy...you can tell from my mods I have spent a little bit, but im right at 18 street, 20-21 highway

 

i get crap for milage because mine foot is always into pretty hard!!!

 

I usually get 18-19 around town and 20-21 on the highway.
