Hello all, my name is Kevin and I recently purchased a 2006 Chevy Cobalt SS S/C. I've been reading the forums for a few days now and I am excited to find so much information about this car!

Anyway, my question is this...I have read a few times around and on other posts noticed that people get 26+ MPG with their cobalt SS. mine only gets around 21-22...could this be spark plugs? the car has 72k miles on it and I have only owned it for about 2 weeks.

I use 91 octane btw

 

how are your driving habits? are you a calm driver or a racer lol. mine gets hit really hard if I drive "sporty" lol. but Im a auto 2.4 lol

 

start using 93 and get it tuned, intake, those things alone can pick it up a bunch, old enough you could prob have the fuel filter changed and the tranny flushed also

 

Do plugs, air and fuel filter, and ummm cold air intake

 

yea it completly depends on ur driving habits.....long trips i get a little over 30

 

I bought it with lowering springs, and I want to do a CAI sometime in the future. I will change the spark plugs just to make sure.

I usually drive sporty, this is my first Supercharged car and I just love the whine lol.

 

The whine is addicting. For best MPG's though try and stay out of boost.

 

and this is y you get such low milage hahaha

 

with mainly highway i can get 36-37. when my car was new i was getting 40-42 with the ac on and 2 passengers.

just do some freshening up maintenance and some light mods with a tune as mentioned by others.

in my experience this car gets thirsty when you drive it like "mustang guy"

 

why is it whining stock? lol mine didnt whine stock only after i put the intake on it and tuned it....and put GM stage 2 on it....

 

It's there but low my friend. I miss my 05 some days

 

did you have any exhaust mods? That'd make it so you can't hear it.
