:lock: my cobat has 500 miles and i only see 23.5 mpg what did you guys think and what's you cobalts mpg??????:lock:

Stay out of boost padawan. :D

depends how heavy of a foot you have lol. i get between 23 and 26 usually, 70/30 city/highway. as of late its been all city and around 24-25mpg.

edit: didnt realize this was in LNF tech, i have a 2.2 just for reference

28.5 with city/highway driving mixed.

was getting 35 cruising at 50ish

26 mpg in mostly stop and go traffic w/ ~55 top speed

I think the minimum I would get w/o beating it horribly each time would be 25mpg

I am averaging 25mpg with the auto HHR SS but I get around 35 on the highway with the cruise on.

right now it is at 23.8

25.5 City getting on it. Over 35 on Highway

50mpg when im not boosting and barely tapping on the gas but when boosting i see 18mpg

^^^lol that's a 32mpg difference

26mpg in town... never on highway

i have 900miles

24.3

^^^lol that's a 32mpg difference

yea it is....:lol:

:lock: my cobat has 500 miles and i only see 23.5 mpg what did you guys think and what's you cobalts mpg??????:lock:

reset your mpg gauge every now and then to get a more accurate reading;)

cobalt gas mileage thread #20. You are the winner!!! :lol:

i average 31 my best 37 with ss/sc stage 2 tune with cold air and 3'' exhaust as
stated before stay out of boost tou will get the best milage = no fun

I'm just over 1000 miles and have averaged @ 27mpg. I think if I really tried I could get around 32 mpg for a week with mixed driving.

My speedo reads fast and my computer mpg is always 1-3ish mpg high, I figured they were linked together, anyhow...

I recently hand checked it with some city driving, mainly highway, and 5 passes at a 1/8th mi track and i got 28. With 5 passes, I'm sure atleast one other time I jumped on it, I thought 28 was awesome.

I checked it again where I only jumped on it once or twice and I got 31. Stage 2, 2.9", exhaust, intake, HPT tuned slightly. Not bad at all if you ask me.

28.5

32 avg. with a 2.4 sport and 28 with a SS SC

35mpg returning from VA this weekend:

City Mileage driving out of boost:

http://cobaltss.net/gallery/files/2/6/1/3/6/city_mpg.jpg

Although I usually average about 25mpg mixed highway and more city getting into the boost.

26mpg city/highway.

25 city
30 hwy

new tranny installed

23 city
27 hwy

wtf

alright, here are my data points so far:

Date--------Mileage----Trip OD----Gallons In-DIC MPG---Calc MPG--Difference -Rating (1-Harsh > 10- Easy)
6/9/2008---188--------170---------7.2---------25.3--------23.6--------7.2%-------6
6/11/2008--382.8-----212.8-------7.7---------28.2--------27.6--------2.0%-------8

with about 80% highway and 20% city i'm at 27.5 mpg and about 650 miles on my car...however...I've heard that sometimes your fuel mileage will increase when you have put some miles on it....probably around 1,500 miles....sometimes the computer runs rich when it is brand new to make sure the engine is properly broken in....watch your fuel mileage once you get past this point and it will probably improve...

also...those guys that were saying they can get 50 mpg barely tapping the gas....i can get 99 mpg coasting....so that instantaneous mpg is irrelevent!

Well i am getting 22.4 in my ss/tc and that is all city driving pisses me off i get stopped at every damn light, i drive 3 miles to work so yeah

I know this is LNF section....but i have gotten 31 hand checking and 31.something with DIC, and thats when driving the PISS out of it on highway on ramps and running 80mph when on the highway (on ramps about 25-35% of driving, no joke, take one to work which is 3.2 miles away going there and one back which is 2.8 coming home). Any hill i encounter i push in the clutch and pop it in neutral or when slowing down, thats how i make up for the having fun :lol: I have a 2.2, hopeing like HELL to get a boosted balt soon though!

33.4 Highway with some boost and 29.5 city if i boost and 27 if i punch it. 93 with octane booster. It helps a lot

31.8 mixed

Well i am getting 22.4 in my ss/tc and that is all city driving pisses me off i get stopped at every damn light, i drive 3 miles to work so yeah

3 miles to work lol, you shouldn't care at all

ok so i drove from almost reedsport oregon back to almost coquille oregon prolly like close to 80 miles i was on completely empty barely putting i was getting like 45-50 mpg lol
in my 2.2 no shit

530 miles, 29.5 mpg avg and riding! ls coupe ECOTEC XFE

dont go by your mpg, go by your final miles driven on a whole tank of gas...

3 miles to work lol, you shouldn't care at all

yeah i know but i hate having the meter now cause all i do is try to improve it, my old car got 16 mpg for the same route so not complaining, i fill up about every 2 weeks i finally got 300 miles on my ss/tc after purposely driving it more

Yea, you are lucky, my work commute is 70 miles a day + whatever else I drive. I got the car last thursday and not going too far out of the its already past 500 miles. The warranty is going to go quickly at this rate lol, well that and the tires.

18.5 all day city

dont go by your mpg, go by your final miles driven on a whole tank of gas...

firs ttank i got around 375 but i was runningn on fumes by the end, i'm at 550 miles with half a tank on my second fill

i get 30 in city only driving....thats driving like a grandma. I'll push 35 highway.

Don't reset it every few days. let it go a few weeks...if you can bring it up over the long haul then you know you are getting good mileage. It averages your mpgs over the long haul...

for example. if you are at 28mpg for 200 miles and are able to bring it up to 29.5 at 300 miles then you were really getting well over 30MPG that last 100....make sense?

I just drove from Mayport, FL to Bremerton, WA (roughly 3200 miles). Did it in two days and made about 32 (at an average speed between 75-80) MPG for the entire trip.

Now that I'm in town and driving in the city I get about 26-28

I get 31-32 highway, 25-26 around town with 1850 on the odometer now

500mpg

i run it on the blood of little children and drunks. incredibly efficient, just hard to find filling stations...

:lock: my cobat has 500 miles and i only see 23.5 mpg what did you guys think and what's you cobalts mpg??????:lock:

thats not that bad if thats the average between city and highway, if thats what you are getting on the highway then yes you are getting bad fuel economy, I usually get over 30 on the highway.

After 400 miles on her with mostly naughty driving. 24-26 mpg

Stay out of boost padawan. :D

hell ya thats a big difference haha

28.5 to 29.1 during the week driving to work.
Most of that is HWY but about 10 miles of stop and go going to work. I do get a brake on the way home at 3 am with very little traffic.

1 35 mile trip on the HWY I was avg 32 mpg.

In September I will be driving to Yellowstone and that will be almost 4000 miles so I will really get to see what she will do on a really long trip.

I have been getting 27.+ on average. That's with a few blasts through the gears every time I'm in it. I do try to remember about saving gas while I'm driving maybe like 20% of the time driving. Approx. 1200 miles on the car.

on the highway i was geting 34mpg

well, i just did an 1100-mile round trip to my family reunion...that's a lot of highway miles, and a lot of ass-backwards make-one-mistake-and-you'll-fall-off-a-100-foot-hillside-in-WVa roads where you don't have the option of safely doing above15 mph, uphill, for 20-30 minutes at a time.

and for the 1100, I averaged 33mpg. about 780 of those miles were highway, rest was...dangerous. lol. and way home, the highway miles were all 80-85mph...i was tired of driving and wanted to get home already.

and you can ignore my post, because i forgot this was a ? for the LNF, not LE5

These cars get their best MPG around 40~45mph in 5th gear. I was able to keep a constant speed with the cruise on for ~15 minutes straight on a relatively flat route. With no A/C, cruise on, 5th gear at ~42mph, I was getting 41 MPG. :)

Ive been keeping track of this pretty closely seeing this is the original reason that lead me out of my Avalanche and into a little 4cyl. haha. My TC has been getting between 260-270miles/tank, and thats with "not so conservative" driving :D. Figure 13.2gals per tank, so Im only getting about 20mpg city/highway combined. I know it can do much better than this, but I dont care because I like going fast! haha Plus, its better than the 13-14 I was getting in my truck, and definitely better than the 8-10 my Vette gets.

i was getting about 28 untill about 800 miles now i get 32 highway..............
took me a 1200 mile trip, car has a really nice ride
