is your odo recalibrated? if not i bet you get better than that.

 

Best 21mpg with gibson exhaust and stock tires
Best with setup now 18-19mpg
avg 17mpg
worst 13mpg using alot of 4x4

33x10.5 BFGs
Intake mod, 3" body lift, flowmaster exhaust

Actually got better mileage with the Gibson exhaust

 

As of 6/21/2005 (the last time I updated my spreadsheet):

MPG: 16.93 (average), ~14 (low), ~20 (high)

I don't really compute best or worst, and because of the way I figure mileage, I sometimes end up w/ really weird numbers (I have a 1.491 MPG followed by a 58.64 MPG!! because I did a partial fillup one day). Looking through my list I'd say my worst got down to the ~14 MPG mark last winter and got as high as ~20 MPG this summer. This last summer I significantly altered my driving behavior and have since been seeing 18-19 MPG reliably for the last few tanks. My average for the last 6 fillups was 19.2 MPG.

Engine Size: 4.0L
Gear Ratio: 4.10
Tire Size: 31x10.5x15
Auto vs 5speed: 5-speed manual

The truck is also a super-cab FX4 LII, basically the heaviest Ranger imaginable.. The engine/intake/exhaust/etc is 100% stock.

More interesting statistics:

As of 6/21 I had had the vehicle for 736 days (2.77 years), had driven 26432 miles at a cost of $0.12/mile. I had pumped 1612.891 gallons of gas at a cost of $2869.01. On average I went 6.13 days between fillups. I used 2.191 gal of gas per day of ownership at a cost of $3.90 per day of ownership.

 

Man, my spreadsheet is detailed, but not like THAT! Can you mail me a copy? lol

 

My spreadsheet is actually based on the one you posted back in the GE.com days.. I just added a few things every now and then. PM me your email and I'll have it on it's way..

 

Wow, my Stang actually gets better gas mileage than some.

 

average 13-15...best ever on a roadtrip..19-20

 

EE is obviously the sound the supercharger makes while the truck is going VROOM.

 

or...Explorer Express...lol





ya i love the whine

 

average- 19.2
best - 22.5 (going 2 n from 6 flags dickin around with my buddy in the excursion goin like 80+ the whole time )
worst 16.1

3.0 2wd 4.10 l/s gear stock 235's only mod is i removed the silencer

 

^^^ me too..i got the best miles after wat ended up being a 330 or so mile roadtrip...and i looked down and still had gas..i was blown away...


cause it was 80mph average and lots of fullthrottle take offs

 

no its not.i dont no i go threw a tank of gas like 2 to 3 times a week and i dont evn drive all that much.

 

Haven't done any official calculations but my gut tells me I get .4MPG....could be wrong tho

 

I get on average 21 summer & 19 winter, my best 28 on long hauls, and my worst 14 but I think that had to do with the gas i bought. I mostly drive 60 + all the time, alot of highway and coutry roads.

ill post with new mpg testing now

 

MPG: 17-17.5, 20.5, 15
Engine Size: 3.0
Gear Ratio: 4.10 n/ls
Tire Size: 245/75/r16
Auto vs 5speed: auto
and any mods you have done to your truck engine/drivetrain wise: SI/DO flowmaster, air silencer removed.

Yes because you have a motor with more then enough power to push it around and you have 3.08's and its manual. However as soon as you change your gears to 3.73 it'll probably drop closer to 15-16. I'm guessing you probably do mostly highway style driving which would explain how your getting 18+. From most the people I know with 5.0 stangs they get around 15-16 in city stock and around 19 highway.

 

before the bl I was getting

best 22 all highway on a long trip
worst 14 all city
aver 17

I have not had a whole tank in it since the BL

spec are in sig

 

I`ve no clue to the mpg but i get 300 miles per tank in a 4.0L SOHC V-6 with a truck rack, im happy with that

 

I just filled up. Pumped 12.786 gal w/ 248 mi showing on the trip. That works out to ~19.4 MPG for the last week and a half (last fillup was 9 days ago). Not too shabby in my experience. FWIW, some of those miles were pulling an 8' utility trailer. Trailer and truck bed were loaded w/ building supplies. It seems having a few hundred lbs of load doesn't really seem to effect mileage much at all..

 

17.5 miles per gallon best, 15 average. 31's 4.10's, and a 4.0sohc

 

prolly above 23 since I got a 4-cyl!!!!!!!!!!!!!

 

2005 FX4L2, 4.0, auto, fabric bed cover, 4.10.

I get 16 in traffic. 18 hiway.
I get 18-19 if I put on the 32" M/T's.
I get better milage with Chevron than with Costco gas.
