Gas Mileage

JKennedy · June 22nd, 2009, 03:57 PM

Okay, so I am curious. Is the mileage in the S197 GT really as bad as the sticker says? It says like 16 and 25 for city and highway.

I'm just curious so that I know what I'm getting into when I purchase. I am trying to decide between a Fox body and a newer S197. So, any information you guys/gals can provide on this issue would be great. I'm sure I'll have more questions as I think of them.

beefmobile · June 22nd, 2009, 03:58 PM

ya it's really that bad lol, and worse if you start modding.

and also i dont think the fox body's are that great either....

pear0119 · June 22nd, 2009, 04:06 PM

I get about 23mpg on the highway with the mods in my sig. In the city I get about 14-15mpg. Its no Prius thats for sure but I didn't buy the car for the gas milage.

JKennedy · June 22nd, 2009, 04:10 PM

Oh, gas mileage won't be the decision maker for sure. I just wanted to know what I was getting into. The wife and I make more than enough to support my vehicular lusts. But, that being said doesn't mean that I am in the habit of wasting simply to waste. So, I just wanted to know what I was getting into. I have seen on here guys getting 17 to 18 in town and then the mid to upper 20s on the interstate.......assuming they are only 5 over the limit. Does that seem accurate?

kenneth · June 22nd, 2009, 04:19 PM

With mods in sig I get 19 mpg with 60% highway 40% city driving and not taking it easy at redlights.
On highway driving between 70-75 mph

If I do most driving in the city it will drop down to around 16

DRock · June 22nd, 2009, 04:29 PM

i believe those numbers are pretty damn accurate if you ask me

limegold06gt · June 22nd, 2009, 04:29 PM

its all about how you drive it 18/27 highway is achievable driving it like a granny

but if your like the rest of us you get 17/26 or worse due to the whole "s197 therapsist" thing

why would you buy a gt if your caring about gas mileage? lol

get a newer one...less problems for now

07 STROKER · June 22nd, 2009, 04:29 PM

ive never checked mine.

pear0119 · June 22nd, 2009, 04:30 PM

Thats about right. Again it has a lot to do with what mods you have.

I reset mine after every tank. Since my gear change it has been just below 17 mpg per tank. It's been consistant everytime. I can nurse it to about 26 mpg on the freeway at 70-75, but I don't nurse it very often. My car sees WOT many times in a day. I lost about a mile and a half in mileage after the gear swap, but that could be because I get on it a little more with these gears. You know it is all about the way you drive though.

TheUNZippee! · June 22nd, 2009, 05:19 PM

I get 24-25 mpg on the hwy with the cruise locked in at 75 mph and with 4.10's out back.

If I keep it under 65 I get 26-27 mpg.

with 3.55 and a k&n filter and 5 speed i averaged almost 30MPG comming home from minneapolis traveling at 70-80MPH.
but now i get about 21MPG and am pushing 470HP to the wheels.
btw i filled up in Minneapolis and made it to Iowa City on 1 tank.

1FUN4RD · June 22nd, 2009, 05:40 PM

with my wonderfull stock 3.31 gears I get 29-30 mpg hiway at 65mph.
On the 700 miles to Elgin,IL. & back I averaged 26mpg. That is mostly highway & averaging 75+mph

DiMora · June 22nd, 2009, 05:51 PM

22-23.

Blow it. Then 17.

2006greyGT · June 22nd, 2009, 08:11 PM

I get 10 in the city with all my mods... 21 on the highway... but I am always in it!!! it will not be worse than that.

chad05gt · June 22nd, 2009, 08:20 PM

If buying 93 octane for your mustang getting around 20ish w/ 'festive' driving, runs too close for you... may reconcider b/c w/ modding, etc... make sure all is good for you financially before you get yourself in a bind.

mineralmustang05 · June 22nd, 2009, 08:23 PM

Wow, on my average gas it hardly never drops 23 mpg I really dont know how much that calculates for street and highways. But I put gas once a week and that average reading includes my weekly friday night at the track with about 12 runs. I guess my cars and outlier.

silverstang · June 22nd, 2009, 08:30 PM

my car currently gets 0 mpg........lol

usnzt84 · June 22nd, 2009, 08:39 PM

i still have the stock 3.31 gears, but i got 430 to the tires, i usually run about 13-14 in town and around 25 on the hwy running 70-80
