What you guys getting mpg wise?

[Lightningquick]

Id rather ask you owners than looking at a magazine article. What kind of milage are you getting both highway and city? Im still hunting my Marauder but with gas jumping 8c here over night it would be nice to know I can get 20mpg out of a merc.

[SC Cheesehead]

About 12 city (my fault)

19.0 - 21.0 hwy

Eaton S/C, 4.10 gears

[Georges93LX]

18 city 24 hwy. Stock with a tune and two rear cats deleted.

[Bluerauder]

16 MPG or less around town depending on traffic volume and quantity of "spirited" driving.

24.5 MPG on the highway long trips.

I really don't pay much attention to MPG .... I just fill 'er up when it gets down around 1/4 tank.

[Blk Mamba]

^^^^ Just about the same as above, stock, with a lot less in the spirited drive.

[DOOM]

6-8 mpg!

Not joking!!!

[FastMerc]

6-8 mpg!

Not joking!!!
Think you have a fuel leak?

[Lignum]

17-20mpg with a 50/50 city hwy split.

79.81 Gallons
1449.00 Miles
18.16 MPG
$302.58 Cost
$0.21Cost/Mile

[DOOM]

Think you have a fuel leak?

No leak. Thats just how it is!

[ntd]

I tried once for a none abusive gas mileage and it was @ 18-19 mpg 70% Highway /30% City. My normal is 13-15 mpg with the same 70% Highway /30% City

[MOTOWN]

seems mileage is changing a bit for the better as stations are switching to summer mix

[visionmercury]

18-22 avg 50/50 city/highway

[LANDY]

Around here
14mpg city and 19mpg highway cruising at 80mph

[yjmud]

25 on the highway

[DOOM]

seems mileage is changing a bit for the better as stations are switching to summer mix

Please explain what a summer mix is? :confused:

[PurdueRifleman]

18 or so in the city, 22 hwy

[fastblackmerc]

Gas companies change the additive package depending on the season for drive-ability & starting reasons. Your mileage will usually suffer with the winter mix.

For all you ever wanted to know about it:

[03sport007]

I was at about 20mpg with mixed driving. Saw 24mpg once on a highway trip. Then I got a tune and it dropped to 14mpg. Thought there was something wrong and forced myself to drive like a grand ma and it went back to about 20mpg. I can't control myself I'm back to 14mpg to much fun.

[DOOM]

I must have winter mix in my tank all the time!!! :lol:

[Lightningquick]

well that sounds great, I was looking for about 20mpg and it seems that should be a given...........now just to find the freaking damn car !

[SC Cheesehead]

I must have winter mix in my tank all the time!!! :lol:

Yeah, that's it!

Been running "winter mix" since early November.... :burn:

[MOTOWN]

i think your confused with a heavy right foot!:lol:

Ding ding ding ding ding!!!

[MOTOWN]

hell i would be too with your set up!

[gdsqdcr]

16-18 in commute (35 Miles takes an hour).

HWY ... No clue yet

[ctrlraven]

I noticed the summer blend being phased in last week, I filled up my 08 Taurus which I haven't been able to get better than 20.4mpg even on the highway. So far I've been getting about 22.7 and almost half way through the tank. I knew something was weird when I normally filled up and it said 391 miles to empty and it's never said more than 346 miles to empty all winter long.

I average about 18-20mpg with 4.10 gears, 3500 stall converter and that's 60% highway/40% stop and go city traffic.

[ctrlraven]

Stupid double post.

[a_d_a_m]

19 city/25hwy pretty routinely. That's with a pretty heavy foot on the pedal. On a trip to Canada, I got 26-27mpg on the interstate runs, and we were averaging 80mph.

My Marauder has the stock 3.55s, a tune, a CAI, and colder plugs. That's basically it.

[Chevyguy]

Been getting 19.5 or so for my 50/50 commute. All stock just changed to 5w20 new plugs and reset. Pcm maybe it will go. Up?!

[fastblackmerc]

I didn't buy my Marauder for the gas mileage.....

If your concerned about the mileage, get a Prius..........

Save more gas for us!

[RoyLPita]

I get just over 20mpg back and forth to work and other places.

[CBT]

:confused: ? MPG ? :confused:

haha, I didnt buy a Lightning for it either, but since I only get 10mpg with it Id like my DD to get around 20.

[Lightningquick]

:confused: ? MPG ? :confused:


I see no reason for it not to be a concern for me, Im not modding the hell of out it so whatever they get stock is about what im looking for. I just want to know that im not going to have a wallet buster on my hands with the prices going up like they are. 20mpg is good enough for me, thats double what my Lightning gets right now, and thats going to GO DOWN once the new longblock and fuel system goes in. So the Marauder would be a DD for me :D

[ctrlraven]

It's a double edged sword with this car.

Stock you will get decent mileage but you can get better gas mileage with a tune, intake and opening up the exhaust some. The other end of the sword is that those mods will make you want to drive the car more. lol

Now that I think about it, I know for a fact someone on here has owned both at the same time, he could probably give you the best answers when it comes to comparing Lightning/Marauder MPG's. I think it was gmtech?? Maybe they will chime in for ya.

I hear you :beer: im going to stick to stock as much as possible. A tune and maybe a catback kit and thats it. unless I start getting my rear skint by local hondas :cool4:

the lightnings are bad on gas from the get go with the weight and 42lb injectors with dual pumps, lead feet dont help either. then you get into going built with TRIPLE 255 pumps and 80lb injectors.............its all over then :shake:

I've always liked the Lightnings.

[Lightningquick]

I've always liked the Lightnings.

Me too brother, I wanted one when they first came out in Gen 2 in 1999 but at the time couldn't afford to pay 45k for a truck. So I waited forever and bought my 2004 in April of 07, hell I still paid 30k for it but its been a great truck and Im still playing with it and loving every drive in it. Kind of the same thing with the Marauder for me, Ive wanted one for a while but haven't had the real reason to get one until now, with the addition of my second son the call for a large car with room for 4 is present. What better time to get a Merc :)

There is a stunning color blue one in my 'hood, it rarely comes out but when it does the whole block knows it is passing by :burnout:

[Fosters]

I didn't buy my marauder for mpg either, hell, it replaced a 50mpg diesel jetta, but it sure will feel nice to double my mileage when I bring it out of hibernation and retire the Excursion for the summer. :o

Wonder if an exhaust, tune, and some lighter wheels and tires would allow MMs to get close to 30 on the hwy... My mustang almost did it (28mpg from phx to san diego) with 4.30 gears and exhaust/tune/lighter wheels, though that weighs about 1400 lbs less than the MM...

I too am a closet lightning fan... When I bought the mach, I looked long and hard at those as they were close in price, but I bought the mach because it got better mileage and they had a back seat... 1 year later my mach didn't have a back seat anymore, and for the past 4 years it racked up about 600 miles total... Should have gotten a lightning :D

[LIGHTNIN1]

Mpg? Whats it?

[Lightningquick]

Mpg? Whats it?
in the Lightning world its not miles per gallon its " smiles per gallon" :D

[CBT]

in the Lightning world its not miles per gallon its " smiles per gallon" :D
There was a video on youtube a couple years ago of a white lightning on some old farm road that must have blazed the tires for ten minutes. It looked like a volcano erupting he stood on the gas so long.

[ctrlraven]

There is a few other little things that you can do as well. Mach 1 chin spoiler, rear skid plate/pro guard, JLT or K&N intake (JLT is a lot cheaper), remove the 2nd set of cats, do a custom mid-pipe, mufflers of choice, larger over axle tail pipes and either gut your stock tips (remove the resonator in them) or buy a new set of res-delete tips.

[Paul]

Avg 14 mpg city, low 20's steady highway cruise

[jsignorelli]

I was getting 19-21 on the highway before making my mods. Now, with the K&N cold air kit, Granatelli 65,000 volt coil packs, and the full SW exhaust, including long tubes, I'm at 24-26 highway. The RealSpeed/SCT tune didn't hurt either. Tons of power and respectable gas milage. I don't use it around town, so I can't comment on under 50 MPH milage.

[Bradley G]

Usually Sixteen with some spirited driving on occasion

[03calitejas]

just back from an emergency round trip to chicago 2 weeks ago and I got 20.2mpg on the way there (ran about 75-80 with a few miles at higher speeds as I was in a big freaking hurry) and then 23.5mpg on the return trip up north as I wasn't in a hurry and prolly averaged 65-70. Respectable mileage for a big heavy comfy fun baddas sedan having 150k+ miles on the odometer.

PS. Don't ever try to use tylenol PM to get sleep because its cheaper than the OTC sleeping meds. My son lost his job and girlfriend in the same week and was a mess mentally. He was not sleeping at night and the benadril meds were being used to keep functioning and go on job interviews etc etc...he is your typical 23 year old that thinks he's invincible and warning labels are for other people. In one week of taking Tylenol PM well beyond recommended doses he managed to kill his liver...I mean totally kill it. He luckily survived the ordeal by getting a liver transplant at Northwestern Hospital in Chitown...I will post this separately too as a public service thing.

[myrodr]

just ran mine on 800 mile trip got 21-23mpg. i have 4:10 gears and tune (Lidio) i get 14-16mpg around town. i think that will change after S/C is put on, but smile per gallon will go up.

[boatmangc]

I usually just laugh these days, it is a losing proposition, the better I get it to run the better it should do on MPG
But, the better it runs the harder I drive it the worse I get.
Last run from Stuart to the Keys (250 miles) I burned 3/4 + of a tank. Got a good laugh. :drive:

I have seen as many as 460 miles from a tank.

[Bradley G]

I wonder if the OP ever got a Marauder? He still has his Lightning posted in the timeslips, ,.. ahead of mine :bigcry: :lol:

[mgmsleeper]

I just gassed up did a 400 mile trip start to finish on one tank

[71cyclone]

6 to 8 miles per gallon with 500 horses is still impressive . STILL GETS THE JOB DONE.
Deffinition of summer mix= Additives removed from fuel to make it burn slower ,less mollicules to decrease density [ Quote from Fleet Service from Baltimore delivery ] lol

[BirchMarauder]

I get scared after 375. The lights usually been on.

[Guittard22]

my monster show truck gets 9mpg city and 13mpg hiway



6-8 mpg!

Not joking!!!

[Tnbigbody]

i took a trip from north TN where i live to ATL for a six flags trip and got 30 but that was granny driving and drafting (at a safe distance) off of 18 wheelers but also gotta say most of that was down hill

[MyBlackBeasts]

21/23 stock with Lidio 91 octane tune & KN CAI - 25% WOT!!! :burn:

So the Marauder would be a DD for me :D

Then go with stock & a tune. The OEM tune is terrible. If you get a tune it will run & drive 1000% better and probably even get better mileage. Mine did...:coolman:

[babbage]

Measured 22 highway @80 with a full car and trunk. Tune will get you better mileage.

What app are you using?

It's an app from the iPhone called Gas Cubby. Good little app. I have my Ranger and Honda Shadow on there too. Keeps track of everything.

[ZACHARY]

I get 20mpg city/suburban easily on my 2004 more or less stock. Have K/N cold air induction and "Superchip" which I guess are a help. On long Interstate cruising I average more like 24 to 26. I always plan to set cruise at 55-60 to what I COULD get, but soon fall into traffic flow at 70 to 80. Like others have said, I didn't get this car for fuel mileage; but it IS only a couple of mpg less than my 2003 Grand Marquis LSE.

[Bradley G]

I can get 20, but I usually get 14-16

[guspech750]

I get on average, 2,000 smiles per miles!!! :burnout:

[92BlackGT]

when i went home for the holidays in December, i got 24.6 mpg on the OKC to Amarillo leg with cruise set to 71

[Roadwarrior]

17 mpg city/23-24 mpg highway with OEM tune.

[capt512]

12-13 city, can get up to 22 if all highway at 75mph
