Well, in my ****-retentive ways I've been monitoring mileage. It largely depends how much is town or freeway driving as both of those decrease mileage. My daily drive is 8mi hwy, 4.5mi town. I think it only does low 20's even with that mix due to very frequent stopping in those 4.5mi...this town has no extended runs w/out stops and people always darting out into the streets on mopeds, bikes, or on foot. The time I got high 30's was because it was just the portion of driving down the keys which is 45 to 55mph, so that's easy to see. I wish I had a V8, but can live w/ this given the mileage I'm getting. I'm always happy with it when I hear people complaining about their trucks and v8 cars' mileage

PS: Those are from doing the math. The car's computer has been from .2 to 1.5mpg high. My odometer is close but not exactly on either as I've used GPS on trips couple trips.

love my SS

ive been getting close to 37 mpg on my SS on the open road at 60 mph. Ive found that that is about the best speed to get high gas milage... no boost and lower rpms. anybody else getting this kind of milage? using sunoco ultra 94 gas, flat roads also

bondrey

the more I go over the 50's mileage tapers off. i'm driving flat roads too. not sure if it makes a difference, but here in key west it's mid 70's winter and high 80's to 90 in summer, always very humid.

i use 93 octane phillips 76 when at home, 93 of whatever brand when going to the mainland.

retrop

I've gotten about 31 mpg running a constant 80 mph going out I-70 in western MD. And any slower or faster and i saw the mpg drop.

TRM85SS

Has anyone checked their gas milage for their SC/SS? I am aware of what the window sticker says, but I am interested in the actual milage.

25-ish city, 30-32 highway...usually.

BeastlyTA

I get about 26 city and havent really been hwy yet.

l337m4573rpyr0

around 27 city, 34 highway if i take it easy. subtract about 3 mpg if i dirve hard/fast.

GeoChevyCobalt

I have gotten about 17 to 25 in city. Highway I gotten between 25 and 37. On average I can get around 30mpg city/highway with some racing on Friday and Saturday. I think that the car gets really good gas mileage if you stay out of boost but it one of those thing that you can say " I do not really need it but its nice to have it). Also i can get around 280 to 340 miles out of one take of gas.

dimeo09

i can get around 35 highway aslong as im crusing at 65mph in my SS and anywhere from 24-27 city

2K5SS/SC?

I get 20-21 in the city, and I haven't quite made it to a long highway drive yet. Charleston trafffic is always stop and go. Boost is fun may also have a factor why it is low too!

Maverick

I get about 21.5, alot of stop and go driving.

SilverSS/SC

I always get 23-26 mph in the city . Trips that have been all hwy I got as high as 32 . That is with me doing the math , the info center never seems to be too far off being accurate though . Just FYI , my mileage has improved ALOT since the car was new . The 1st few thousand miles my gas mileage horrible 17-20 city and bout 20-21 on the highway . For some reason , without change in driving habits the mileage in mine has just got better over time .

When I first picked it up I was getting 22.0mpg, now that I've put 2,600mi on her I'm seeing 24.1mpg at the momment. I have seen up to 29.8mpg on highway, but I'm usually out in the country where I need to shift alot.

DanJHartman

yeah..I probably get on my car a little too often...so im running about 21 mpg overall....although i can get better on highway..up to like 35mpg

theBLUEone

I have been getting 25.3 mpg city and on long trips I can get around 30-34 all according to the in-dash mpg guage....

skoshi130

When I first got it it was below 20mpg's(city) roughly estimating around 27mpg's(city). Have not done any over the road trips yet

slvrbalt

well i probly get about 22 a gallon all city drivin here lol i hate that estimated gas mileage thing

BeastlyTA

If you just reset it while your driving you can see what your getting in almost real time. Pretty cool feature.

stic5

How are people getting 35 mpg on the highway?? I have never hit 30 mpg for any significant stretch. Maybe it has to do with the fact that I always drive close to 80 mph on the highway?

zinner

Guys this is like the 10 million 'th thread on gas milage do a search before you post. Especailly on something as common as gas milage.

Merging this with another gas milage thread.

skoshi130

I just took it out on the open road today and I got 37

Frenstall

If I dirve 110km/h I get really good gas mielage. If I go up to my usual of 120km it drops off a fair bit. It seems almost as though 110 is about it's sweet spot. I really do think this car needs a 6speed just to give it better spacing on the gears and quiet it down on the highway. I'm sure with the Solstice/Sky going to get the 2.0S/C there will be continued corporate support for this engine

jaded

Is anyone else getting really crappy mileage even after they've broken their engine in? I'm at 10,000km (as of yesterday) and i still average around 10.5 to 11.5/L per 100km. That's no where near the advertised 8.5L/100km combined city & highway (30 MPG).

I don't get it...I drive at relatively low RPMs and generally drive like i'm trying to save every last drop of gas. 375 - 410 km a tank for my LS just doesn't make sense.
