Okay, so like everyone here knows, I'm strongly considering buying a Cobalt, I've read EPA estimates of 21/30 on the SS Supercharged. I'd like for all you guys to post your Cobalt type, year, and gas mileage if you please, and any other little quirks.


This is eventually turning into a mini-science project of mine. LOL. Oh, and has anyone ever owned a 97 Taurus GL and knows the EPA estimates on that. I'm trying to clock it on 87 octane vs. 93, and I want to see how the car performs with the two.

Thanks!

Its preatty close to the projected EPA!!

martinsmu

but it all depends on the way you drive

onefstgtu

I've had anywhere between 28 at the lowest..mostly around 33...And my personal best 41.1 driving like a old lady...

martinsmu

My brother has an F-150 that only gets about 17 in the city and 20 on the highway. 21 on the Supercharged really isn't that big of a difference, is it? Also, how is the Supercharged efficiency next to the plain SS'es?

martinsmu

OH buddy, you deff get alot better then you brother with his F150 for sure!! no worries about that!! EPA estimates are driving 70km/h ( about45mph) on flat land. In reality, you are going to do alot better than hom for sure!!

The worst I get is about 24 mpg, highest I've gotten was 33 mpg, average is about 26 mpg for myself.

Cobalt_Supercharged

I have an 05 SS Supercharged. I typically average 22-25 with my normal driving which is mostly in town with the ocassional freeway venture. I typically open it up once or twice a day but try to drive it nicely the rest of the time.

My best was tank was 28 and that was going to California while loaded down for the weekend and with my buddy at the end of December. Our average speed was around 78 according to the computer and that includes stops. We also fought a 20-30 mph headwind when going through the "Windmills" which is an uphill climb.

tcolli17

Same for me. If you don't open it up except maybee once or twice a week, you can expect 26-31.

I find it hard to believe some of the MPG you SS/SC people are getting.

If you're using the DIC for calculations, you may want to check your actual MPG with a calculator.

My DIC says I'm getting 32 mpg.

I actually get ~26.5 mpg.

If you're truly getting above 35 mpg, I really like to know your secret(s).

Even with me *****-footing the throttle, the best I've ever gotten is 28.5 mpg.

my computer says 26 now, ive seen it hit as high as 27.2 i wonder if this is just cause its new

BlackyK

I get 26ish in town, and up on the highway its 35-38. Cruise Control in 5th ftw!

HickOverLOrd

06 SS/SC, DIC usually says around 29mpg. Im gettin just short of 300 miles on a tank.

BlackyK

^^ I just went 418 on a tank, 350 of that was highway, and 320 of that was cruise control.

blackda

Atlanta traffic...
87 octane = 22 city / 26 hwy
92 octane = 24 city / 29 hwy
long hwy trips (5th gear @ 75-80 mph) 32 mpg

I'm averaging 21.8 MPG for the last couple weeks, mostly due to having a couple nice long stretches to and from work . While I was still babying it getting used to it I got a nice 28 MPG though.

Johnboy12358

My DIC hovers between 20-28 depending on how I have been driving. I usually get 300-350 miles in a tank of gas

montecarloman

06 cobalt, 2.2, manual, steady low 28 mpg evey week.

Cobalt_Supercharged

I calculate it every once in a while. Everytime I do the DIC is ~mpg higher than calculated. I corrected for it. Oh wait the 28 was on the DIC, so it was probably more like 26mpg. Even still that is pretty good considering I was cruising at 80-90 mph most the way with a ~20 mph headwind while going uphill.

The trip back wasn't nearly as good. I guess WOT at 125mph in 4th doesn't help gas milage too much.

I keep my MPG in a log using the old fashion miles driven/gallons put in at fill up. I did quite a bit of experimenting this summer because I was driving the same 32 mile drive everyday for my job for a month straight and I found taking the old highway (speed limit 55 drove 58 on cruise) I got 34.2 mpg. Taking the interstate (speed limit 65, drove 68 on cruise) I got 28.5. Going 75 on the interstate I got 28.5. I tried to stay as consistant as possible which meant shifting from 1st to second at 3k rpms on the on ramp and then going wot until 65. Going the old highway I would do the same except for let off at 55mph.

Now that the election is over and I don't travel any more and I work in an office two miles from my house everyday which is in a small town I have found that I get around 22mpg. Top speed is typicaly 35mph because the top speed limit is 30. I usually shift around 3k rpms.

Obviously my experience show you get less mpg in town. duh! lol The moral of the whole story is that the 5 speed seems ideal for 55-60mph cruising. As with any FI car the less you boost the better your mpg will be.

It sounds to me from the posts you have made regarding gas and mpg that you are on a tight budget or just really freaking worried about something that is minoot. This car gets good mpg for as much fun as it is to drive, but if you really are on a tight budget or just **** about mpg then I suggest getting something like a civic, corolla, or aveo. When you push the SS/SC the mpg goes down fast.

2006 2.2

Stock = ~32mpg

After mods = ~ 25mpg

would simply putting just an intake on have any effect on mpg, i been thinking about getting one for the power of course but just wonder what effects on mpg it has

D4u2s0t

well, the theory is simple... add more air flow, use more gas... just an intake by itself is not bad, and may increase it by one or 2 mpg... may decrease by 1 or 2mpg... either way, it won't be significant...

alleycat58

SS/SC, I get around 27mpg average driving (city/highway mix) and about 34mpg highway, both calculated, not DIC. Highest I've gotten pure highway was 40.4mpg, I went for a brief period where I was getting 37mpg highway fairly regularly.
