There are a ton of threads about mpg and what people get and some people dont buy what people are getting for fuel economy so here is some proof i have mustered up last night:



317 - miles




Right above E

Fuel light still not on.


Filled up and it took 15 gallons.



So 317/15 = 21.3 mpg

 

Oh and its a 4.0L 4WD with 4.10's

 

I have put in 16.5 gallons before but didn't calculate MPG. My fuel light didn't come on either. I have the same truck and I get about 21 MPG too.

 

Yeah alot of people though say that us getting 320+ to a tank isnt possible.. or just doesnt happen.

Where i got 317 to 15 gallons is great and mine was cruise controlled at 77mph the whole time.. which i would say that is great gas for our truck.

I am just backing up our fuel econ claims.

 

Nice! My scanguage says that I can get 320 to a tank, I just never let it get that low.

 

Nice.. Yeah i need to get a scangauge.. right now i use.. well the NOKIA 6555 CALCULATOR model hahah..

But i was inpressed that at 77 mph i get 21mpg. I wonder what i would get at like 65mph.. or even 55mph.. haha.

 

Yeah I ride at 68 now lol, that gives me the best. Anything over 70 its dropping out of gear all the time.

 

I do too much in town driving to calculate a true mpg. But on a general week I believe I get about 18mpg.

 

what have you done to the motor? I/E

 

On my 4.0.. is just K&N drop in and magnaflow single out exhaust..


Plugs are done but IDK if they help..

 

What do you mean dropping out of gear?

 

so do you have the 20 gallon tank?

 

Dropping out of overdrive for more power lol

 

I think its 19 or 19.5 but yeah i do. light comes on at 16 or 17 gallons gone.

Ohh i forgot.. AUTO.. duhh.. haha.

What do you run at rpm wise at 68mph?

 

I'll have to look next time, its between 2000 and 2500 though. Probably about 2300

 

Thats not to bad.. cause at 77 - 78 im at like.. 2900

 

I'm to chicken **** to let it go that low lol

 

I ran mine to like 15.4 g is what the fill up which wasnt bad.. Light was close though.. I have had light come on and only put 14 gallons in..

 

Well if you were driving around in 4lo with a messed up 4wd detector. rofl

 

HAHAH.. nooo nooo its been fixed so its not messed up anymore yay..

yeah that would be funny.. but i never use 4low.

 

You could have easily put a few gallons in to get more mileage...surprised no-one called BS yet. I get around 320 miles to "E" on the "gage" (Ford's spelling)

 

on my 33s, best ive gotten is 315 to the tank. i forget the gallons. my foot had alot to do with it.

i just sucks around here though becasue on the highway, you have to run 75-80 or you get honked at, swerved at, and given the finger. people are *******s around here. i like to poke around i dont give a **** how long it takes me to get somewhere.

i want a scangauge

 

wow i stand amazed by this.. but i know you have alot into your truck..


oh and what do those gauges look like lit up eh??

 

i've gone from 19mpg when i got it down to 14.5 right now with 33's 4.10's and 5spd auto. i just filled up yesterday. and here is where my truck is at. and my driveway is up hill so my gauge reads fuller than it actually is.


and yes its an 03 with that many miles
