is 10 miles a gallon normal
 

i have a 2001 extended cab 4x4 with the 5.4 and 76000 miles i cant seem to get more than 11 miles a gallon and thats driving normal. i was thinking of having it looked at and maybe a tune up. it has a mac cat back and 285/75/16 pro comp xtreme terrain tires and a 2.5 inch lift/leveling kit. i only lost one mile per gallon with the tires. if anyone has a suggestion it would really help thanks

WoW LUCKY!!!!! I get around 8 miles to a gallon, but an overall tune up might help your problem probably mine too :lol:

You'd be surprised what new plugs and wires can do to improve gas mileage and overall performance. Granted they are a PITA to replace they sure do show good results.

HAHAHA you mean COP's i dont believe 5.4's have wires but about 8 of these sure would be nice:lol: http://www.accel-ignition.com/Produc...minselection=0

I think its just the way these trucks are... I have plugs with around 8,000 miles and notice no difference. I have tried quite a few things to improve mileage as well as performance. E-fans, clean K&N filter every 3rd oil change, clean maf, keep tires inflated, diablo sport programmer, tried keeping it under 70mph/2000rpm's, keep windows up. Nothing really works for me, maybe the 02 sensors but ive been told to just wait until you get a code.
Currently getting around 12 right now if I dont get into it.

i think i will have a buddy of mine do the plugs he is a ford master tech. then i can worry about my plugs losening up for the next ten thousand miles

Just did my O2's and it didn't do SHI!!.... ya you know what i mean:lol:

i have only had the truck a few months i guess i will have to suck it up

Didn't really pay attention to the year, just referencing my plug and wire change in my old 1997.

Changing the EGR valve made a huge differance with my milage.

i will have my buddy check the egr. thanks i noticed if you drink a twelve pack and squint your eyes my truck really looks like a 07 i just have to figure out how to get it to drive like one!:beers:

my f-350 v-10 gets 11-12 mpgs. doesn't sound right.

it goes to my buddy next tuesday. 230 miles to a full tank sucks i hope he finds something wrong

11's all I get.

i only get 11 as well. You might try replacing the fuel filter, A clogged fuel filter can do a number on performance.
