What is your MPG

[Brandon]

Now this should be averaged under normal driving condition.

I only ask because I just filled my tank from the half way point and when I went to reset the trip it said 140mi. Now I thought this was good... Till I did the math and figured out I was getting 16.77mpg roughly.

I am curious to what everyone else is getting.

[CWright]

How many gallons do we hold in our cars?

[Mr. Man]

18 to 20 combined driving. Got 24 once, all highway and easy on the gas

[Blk Mamba]

^^^^^ thats about mine too.

[ntd]

18-17 mpg's combined do about 60% freeway and 40% city, I dive my car on the hard side.

[justbob]

Best ever - 22 1/2
Normally average - 10

[Spectragod]

WOW, you're getting 10 MPG, I judge my economy on how many tanks I get to a set of rear tires. :D :burnout:

[jdando]

15mpg lately. Winter is coming and it will drop to 14 :(

[justbob]

Thats probably an easier way to compute! :beer:

16-18 MPG around town is about my average. Less if traffic gets stalled. Long trips on the highway like to Indianapolis, IN for MV7, I get 24.5 MPG.

I think we have a 19 gallon tank. Most I have put in is just under 17 gallons.

[Brandon]

Well even though I drive on the "hard" side it seems I'm getting about average then.... I was worried for a minute. I was like "I just had a complete tune up how can I only be getting 16mpg". 25$ for half a tank is crazy! 25$ in my other car will fill the tank, Not to mention I get around 20-25mpg in the city (When I stay out of the +side of the boost gauge haha)

Thanks. I figured that was around what we have. I don't let mine get below a qtr of a tank before filling back up. When on the highway cruising at 78 mph I went 320 miles and needle was on qtr of a tank. That was driving home from Jacksonville after picking car up from Dennis. I took it easy for that leg but had fun after filling back up and going the last 80 miles to the house.:D

Since we're talking about a Grand Marquis, my Grand Marquis got 20mpg on a 50/50 city/hwy.

Best was almost 27mpg on a trip to VA one time, A/C on and 70-80mph.

Worst was 17mpg while hot rodding through a mountainous Pennsylvania countryside.

[Brandon]

Yea but don't forget, I do not have a Marquis tune. My PCM is the same as a Mustang... Now I know the engine is the same 2v but I'm pretty sure the OE tune is different.

Like someone brought up in one of my other threads "The Mustang is a lighter chassis so it can run more timing, Yours is a heavy boat!"

[imorb1994]

The best I have had for a tank was 26 avg, highway with lots of down hill coasting. But regularly get around 15 combined.

My dad's '03 GT gets 21mpg consistently, for reference.

[Brandon]

Well even though I am a father I do not drive like one, I like acceleration;)

[gdsqdcr]

Wow, I thought I was doing poorly. Currently averaging 18.5 in commute. I like onramps, and I cruise comfortably at 80Mph going to work. Course the drive home slaverqges about 30mph.

[RR|Suki]

10 city, 17hwy when I take it real nice and easy.
If I don't, then it gets pretty painful

[ImpalaSlayer]

i dont even check anymore

[Glenn]

MPG is not my thing! Did not buy the MM for MPG, but to run fast and strong.

But for the record my other Ford products - my DD Ranger V-6 5 speed gets 23 mpg at 250,000 miles, F150 4.6 tow truck - 17 mpg at 230,000 miles and T-Bird 4.6 - 20 mpg.

Glenn :burnout:

[Cobra25]

On the highway doing 80-85 with the A/C on 18.8 mpg.

[FordNut]

Prior to my last tune it was around 12, now it's closer to 16. Mostly highway, around town it's worse. Of course it's near impossible to not get into it just a little bit when passing. It IMMEDIATELY jumps from 75-80 to 100+. Rolling into the throttle without a downshift, not stomping it.

[dakslim]

Best I ever got was 26 highway and almost 20 in town...not much traffic here.

[DOOM]

I get about 8mpg :D

[B.C. Bake]

Last checked 12-4-09 all city mileage 19.1 mpg and that's not babying it too much.:)

[mercman04]

:wreath2:IM GETTIN ABOOT 20 MPG A LITTLE OVER 400 MILES ON A TANKFUL

[Glockafella]

I got 23 on a long trip going 75MPH, I get 15 around town

[Brandon]

Some of you guys sound like me under boost "8mpg" "5mpg" haha

[EbonyMarauder03]

My mileage is when I get to a quarter of a tank...fill'er up. I used to worry about mileage, then realized, whatever mileage I get I still have to put gas in the tank. My mileage goes down after a mod. Still enjoying the novelty of my Addco bars. :drive:

[B.C. Bake]

Some of you guys sound like me under boost "8mpg" "5mpg" haha

5MPG woooo, that would get in your wallet, BUT sounds like fun! Daly driver "not so shure".:rolleyes:

[GetMeMyStogie]

I seem to average a tad over 300 km per fill up, mixed about 60/40 city/hwy driving. A fill up is usually about 60 litres. That's about 20 L per 100 km, or about 12 mpg, running Zack's 93 octane tune, and everything else stock.

[Brandon]

5MPG woooo, that would get in your wallet, BUT sounds like fun! Daly driver "not so shure".:rolleyes:

5mpg would be WOT @ 14lbs :drive:

[james79stang]

with tune...my in town is 15-17mpg.
my hwy is 25mpg... but have seen as high as 27mpg.

without tune... in town 11-14mpg.
my hwy is 21-23mpg...

[LordVader]

Avg 16-18 city and 21-24 highway.

[Stranger in the Black Sedan]

Not sure if you're asking about a grand marquis or a Marauder?

For my Marauder, I get 18 mixed, 20-22 highway depending on how badly I am speeding, usually closer to 20. I've had several tunes and none have affected my MPG vs each other. I only drove my Marauder with a stock tune for about a month (I would hope everyone else who bought this car in the past few years when tunes were readily available, was the same way) so I have no idea what the mpg was stock

[justbob]

I drove mine stock for four years.:(

[Stranger in the Black Sedan]

I couldn't have tolerated it, it drove soooo bad with the stock trans tune I thought I was driving a town car except at total WOT when it would actually hold some rpms.

[ReefBlueCoupe]

18 to 20 combined driving. Got 24 once, all highway and easy on the gas

Yup. Stock except for shift points/firmness.

[Marauder386]

Gas mileage ? Hmm.... didnt S/C these cars to be concerned about it...I knew what I wanted to do to them and understood and accepted the cost of feeding our monsters...


:cool4:

[fastblackmerc]

How many gallons do we hold in our cars?

Capacities are in the owners manual.

[fastblackmerc]

If I cared about gas mileage I'd be driving a :down:Prius:down: :eek:

[matth]

The best I've had so far is 22mpg I average 18.25mpg, but if I get into a heated highway run for some miles... It drops to 10mpg.

19.24 gallons of 93 octane make me think twice before punching it.

[Marauderjack]

I drove A LOT of highway miles N/A and got 22-24 MPG at 75-78 MPH!!:beer::bows: Around town it was 17-19 MPG!!:cool:

The ProCharger install knocked the highway down to 21-22 and the around town stayed about the same until the DAMN ethanol was put in the gas around here!!!:mad2: It killed my around town.....now 15-16 or so.....but it recently went back up so I guess they are putting the ethanol back in more profitable products LIKE BOOZE!!!:eek::D

It still amazes me that these big ole cars get what they do.....especially mine with over 200K miles on the clock!!:beer:

[BLACKMARAUDER04]

Summer - 12-14MPG
Freeway - 18-22MPG
Winter - 14-18MPG
On one trip I went 406 miles and took only 16.5 Gallons, a average of
24.6MPG (MY BEST EVER)

[CKMustangCobra]

18.5 mixed

[guspech750]

Never really paid any attention to it. I did not buy my Marauder to save gas. All I remember was I got somewhere around 340 miles on a tank a couple of times with about an 1/8 of a tank left.

[boatmangc]

I got 23.5 on the way home from PA at 75MPH
I got 22.5 on the way to SSHS9
Who knows what I will get with the Aluminator :banana2:

[bob6364]

I got 20 mpg heading to VA from CT in mixed acceleration and deceleration ..... I accelerated on the Jersey turnpike and decelerated for the entire state of Virginia :p

[jabird56]

I've been keeping mileage records since I got the MM.



Monthly

Average: 18.23 MPG
High Month (June): 19.48 MPG
Low Month (May): 16.78 MPG

High tank (29JUL08): 28.00 MPG
Low tank (29APR05): 12.85 MPG

[JIMMYDEARMOND]

137000 miles avg 21 mpg in town and hwy 25 to 27. Shell gas only

[LANDY]

on my MM (r.ip). i never got better than 14mpg. im not an agressive driver unless someone wants to play, thats rarely.
does the fact that i deleted all cats have anything to do with the poor gas mileage?
my mod are on my sig.
thanks
LANDY

[Big Black Beast]

I can't remeber the last time I ever checked the mileage in any of my cars.

[Bradley G]

last fill 15.04

[LSp8]

This is by far the MOST fuel efficient car I ever bought. Better than my Taurus. Someone on here asked about the tank size, It's the same on all Panthers " 19.9 Gallons "

On the highway (I-95 :) ) last summer I drove to Newport News, VA while it was raining with the A/C on Low and Cruise Control set to 70 mph, I got an astonishing 27 MPG!!!!!. When I got back home It was a dry Saturday night and I went through the city Showing off and spinning tires and acting the fool all night, got 13 MPG

[Paul]

Around town it's 13-15 mpg depending on driving style. Don't do much highway, but it's prob. in low 20's.
