How long have you had your SS? Do you notice a significant enough increase since you first got it?

 

I sure do, gas mileage was absolute ass for the first few tanks. Still getting better I think.

EDIT: Forgot to add I've had my car for 3.5 weeks now, but I've put on 2600km's already so I'm pretty far into the break in

 

when should i reset the mpg on the computer, every time i fill up for it to be accurate or what?

 

on the 2.2, im getting 34.0mpg freeway. not bad eh?

 

I don't know about you but my ss tank is 12.5 gallons. I am getting about 300+ miles to the tank on 89 octane

 

i average around 24mpg on my non-s/c, i can do real good then i always get the urge to chirp the tires then next thing you know my mileage is way down again oh well its fun and i have a gas card right now WOOO

 

i get 18 mpg city without taking the rpms past 4 grand.... pretty shitty if you ask me

 

Thats usually what I get, when I'm not on it!

 

thats when i do it, i do it the 2nd i start to pull out of the gas station, or else it gets "weighted down"

 

Wow all you guys suck i think the gauge told me i was getting something under 20 mpg. LOL i must drive it really hard. I also put in the shell or sunoco 93 and it was 2.75/gallon. HOLY ScHNIKEeS.

 

It costs between $24-27US depending where I go, typically get about 400 miles out of the tank, I've been as high as 450miles out of a tank. Depends on your habits. Car learns how you drive so be careful...

 

RPM's do not matter nearly as much as the peddle does. If you never give the car more than quarter throttle and rev it to 5 in each gear, you'll get better mileage than 3/4 throttle reving it to 3 each time.

You will also see a significant improvement in gas mileage by not boosting the engine. I found this car's milage very closely follows your driving. If you drive it light, don't boost it, it gets great mileage comparable to any 2.0L 4 cylinder. If you romp on it, boost it often, you will see it drop significantly to that of a lareger V6 or small V8 if you're not careful.

You simply CANNOT get more power without sacrificing gas mileage. That goes for any car. If you drive without taking advantage of the power, you get better mileage. The choice is yours.

 

I just bought my LS last week in Texas and drove it back here to Florida, 1200 miles. 3 tankfuls and averaged 31.5 mpg doing 75-80 all the way.

 

One thing I have noticed is that poweful 4 cylinders don't get good mileage at all.

Friend of mone bought a new car and after a few thousand kms his gas mileage really went up, so give it a little time.

 

I'm on my first tank of gas and it looks like I'm gonna get about 450km on the tank. Not that bad I guess. Well, no worse than my old Z24. The dealership filled the tank so I'm not sure what octane of gas they put in. Definately gonna fill it with 94 when I do. And yeah, I opened it up more than a few times, chirping the wheels. It may not be the best thing for gas mileage but it sure feels good.

 

What? 30+ miles per gallon is not good?

 

lol us with heavy right feet can only dream of such numbers

 

I'm not sure what the Cobalt's advertised MPG is and I'm sure there is a difference between the LS and a SS/SC. Just for comparison, I just drove my Type S (CAI/Hondata) on a camping trip. 3 adults (one in back seat hates me), and hatch full of camping gear. Trip went up and down mountains of Arizona, i.e. 7500 feet. Got home and filled up with 8.4 gallons of 91 octane. Had 267 miles on tripmeter....31.78 mpg. In town.....about 24 with half on freeway and half on city streets.

From what I see, the Cobalts are doing pretty well on gas mileage.

 

yeah mine runs around 24mpg, but that's only cause 90% of my driving is on the freeway(in the city it's almost like i can see the gas gauge going down as the tach goes up lol).. if i milk it on a long drive i can stay around 30+mpg

 

I range from 24.4 to 24.6 alot. Sometimes you just have to take off at the lights im sorry lol. But i get around 300+ miles from a full tank.

 

Well said!

I get about 22/21 on an all city tank on 87 octane 24/23 @ 93 octane on the highway I get about 29/28 on 87 octane and 30+ with premium fuel. (average on/off driving)

-and who is trying to say they get 30+ city driving on their cobalt ss? They're crazy, no way in hell, your car must not be working correctly. Show me another supercharged car that gets 30+ city mileage cause they don't exist.

I have a question for everyone,
Has anyone put in any "fuel saving devices" in their cobalt such as fuel line magnets, or air rifling devices like the "tornado" etc... Do they work at all? with gas the way it is. It might be a good thing to do.

 

I usually only get just over 400KM a tank running on 91 pump from Petro Can. That's cause most of the time I tramp on her in 2nd just to hear the S/C whine. I can almost swear I see the gas needle go down as I step on it

 

usually 530 city ...590 highway

 

well I won't comment on what people get---it varies. The MPG tests are all the same--no variables.

The S/C SS is rated at 23/29 (city/highway)

A 400 hp 6.0 LS2 Corvette gets 18/28 in the same test.
So yeah the SS/SC fuel economy is poor.

 

I have 1080km on my car and i do 10.9L/100km. Ultra94 baby! Ouch
