What's your gas mileage??

15 mpg in town with a heavy foot (same for both stangs).

Checking the ECT is a good idea, and that's good info about it not necessarily tossing a code. The sensor can be out of calibration but within absolute specs, ergo no code.

The sensor uses a thermistor so one can ohm it out (or check voltage) at various temps. Mine's out of calibration at ~ 150*F but within 1*F at 180*F.

Good luck.

8.5 in town...11 if I NEVER get into boost and stay below 2500 rpm....

3.27s, mods in sig
My best city every is 15.705, that is going easy and all city.
My best highway is 26.317, that is about 100 miles highway and 4 city.

wow i'm jealous....my jeep doesn't even get 20 miles let alone 25! I never actually checked my gas mileage on my stang. if i had to guess though, i think its prolly in the low teens.

18 mpg city and 25 hwy considering if i drive easy but i get from 12-14 mpg if i drive hard but i noticed that the 5.0 gets a little better gas mileage when you take the rpm's up a little for example on the highway i get better gas mileage at 75-80 mph than i do at 60-70 mph....go figure

As odd as this sounds, I've noticed the same thing! When I got the 4.10s I was dreading the mileage loss, buts its really not that bad. Especially because around town mileage (where I do 90 percent of my mileage; its a weekend toy) actually got better with the 4.10s.

City - 16ish
Highway - 20ish

With a full tank I do 180 miles.. wich is like 13MPG and my car is almost stock

Took this one step further and did the daily drivers

My wifes civic is getting a dismal 22MGP in the city, why her 2001 is getting so little MPG is beyond me as I don't drive it. My 04 Honda van got me and avg of 25 mostly highway, and I didn't have my foot in it at all, used the CC obeyed the speed limit, Im not impressed.

You want gas mileage get a prius. You wanna drop the clutch and hang em high drive a mustang. Mustangs are toys period they just aint going to get good gas mileage.

I was reading through all of the posts thinking the same thing. Who cares what mileage you get? We all bought our Mustang's for a reason, I can assure you it wasn't because of the mileage.

Come on, that attitude is just ignorant. It's a question of optimization - power and efficiency. If all it was about was hanging the front wheels, we'd all be driving a carbed 408W. I don't understand why people without the capacity to attack an engineering challenge such as high horsepower coupled with good mileage always feel compelled to attack this question.

If one were asking this question at the attempt for optimization, one would then have to compare vehicles on a level playing field. As such, the cars would have to be exactly the same. I would wager that few if any cars on this site are EXACTLY the same. Alternatively, for a stock vehicle, one could compare with the estimated mileage numbers from the orignal sticker. But even then your comparing a new vehicle to a worn one with many miles. In either case your attempt at a comparison is unfounded due to the varying circumstances. Thus, you are left with no standard for what optimum operation entails. You then have no authority as to what the optimum mileage is for your vehicle specifically, because their is no fair comparison to others. This is why this question is pointless. But, in the interest of your quest for optimization, let's take this a step further.

While we may not know exactly what the optimum mileage for your vehicle may be, we could however find a general area by which we would expect your 5.0 to perfrom OPTIMALLY. For the sake of argument let's say this number is 15mpg. Now say your car is operating at only 13mpg (I feel that for a given setup, losing or gaining two miles per gallon would be significant. Most likely a very noticible difference in performance and overall driveability). Using this figure, over the course of a year, driving 12,000 miles, this would necessitate 923.07 gallons of gas. Taking California's high per gallon rate of $2.49 for 91, that would leave you at a cost of $2298.46 for the year. Alternatively, if your car was running OPTIMALLY, at 15 mpg, over the course of 12,000 miles you would consume 800 gallons of gas. At $2.49 that would run a tab of $1992. From this we can conclude that the OPTIMIZATION of your vehicle would net a saving of $306.46 over the course of a year. Or about 84 cents a day.

I understand your train of thought and if it makes you happy to pursue the thought of optimization then so be it. I am in no position to judge you for that, nor would I encourage you to stop. But being that this is a forum, and it is all about opinions, I have mine. That opinion is even if I did know the mileage my car should get optimally, which is clearly impossible, 84 cents a day is not going to make the slightest bit of difference in my life. Slightly wasteful, maybe, BUT PLEASE DO NOT CALL ME IGNORANT.

Low-5.0 said:

Usually 12-14 about 50/50 city/highway. I can probably get over 16-17 if I keep my foot out of it and drive mostly on the highway. That's with 3.73's and TKO 600 trans(.64 OD).

Not bad with a 418inch motor.......I get like 18-20 with 3.73's and h/c/i.:SNSign:

about 12-13...running pig rich with a vortech...Thank God for the Escort!

Ji
I get around 10mpg mostly city and around 15 on the Highway..

3.73 gears

What part of California has $2.49/ gal gas? A more realistic example is driving 12k miles/year with gas at $3/gal in a car that makes 8mpg vs. one that makes 20. No doubt you can do the math and see that we're talking $225 a month. That could be a car payment...

The vast majority of us want more power. For a given hp level, you can have varying levels of efficiency. I could kill a mouse with a hand grenade, but I'd rather use a mouse trap as it makes the clean up a little easier. I could hit 500hp w/ a ton of displacement and just dumping gas down the cylinders, but I'd rather do it while making 20mpg.

My point being, when someone inquires about gas mileage don't respond comments like "that's not what we bought a Mustang for" or "you can't have your cake and eat it too". These responses show a lack of knowledge of the subject. With that attitude, we'd all be modifying our flat head Ford motors.

We have plenty of "opinions" floating around here. All I'm saying is when someone asks a question answer the question with facts, don't criticize them for asking the question.

First, I don't remember ever posting "you can't have your cake and eat it too"

Second, let’s address the quote "that's not what we bought a Mustang for." I have failed to find a portion of that statement that is ignorant. The only way this statement could be viewed as ignorant is if a person bought their Mustang because it netted the best mileage of any vehicle they could buy. I not only find that hard to believe, I know this to be false. This being the case, I would say I'm safe in assuming that it was not the chief concern of any member on this site. Thus..."that's not what we bought a Mustang for." I think this statment can be described as "Accurate" far before ignorant.

Next let us consider your argument on efficiency. I am not saying that I disagree with you. The bottom line, however, is that the optimum mileage of each car will vary. With a given vehicle and engine our power is limited to making sure maintenance is taken care of and that the car is tuned properly. If this is done what is there to worry about. Your not going to change your Mustang into a magical machine that gives you 60mpg like a Prius. The bottom line, is to do everything you can to make sure your car is running well and live with the resulting mileage.

And again, the bottom line so to speak is that people "live with it" because they don't know how to improve it. If you're ok with that, then fine. But when someone asks a question, don't respond with "who cares", obviously they do or they wouldn't have asked. How about we let the thread get back on track, ok?

100% city 12MPG with a stock engine. just ford c7 headers and 4:10 gearing.

my dad has a lead foot. 25% of the new tires are all ready gone.

Hell, I got so fired up about people bashing the question that I didn't answer it myself...

I get around 14mpg, all in town, driving it like I stole it through a TKO and 3.73s with a motor just the way Ford designed it.
