I'm averaging a bit over 25 mpg in strictly city driving. I've made two long highway trips, and averaged 35.0 and 33.4 respectively.

@ $3.39 / Gallon for 87 Octane with 10% Ethanol, I'm averaging a fillup of ~$37.00 every 4-5 days. I average about 280 - 330 Miles per tank if I am pushing it a little bit every day for an hour or 2 total.

just bought my cobalt about a month ago. with my normal driving as well as with my heavy right foot (especially considering how excited i am to have it), im getting between 23-24 mpg. seems everytime i try to do the get good gas mileage thing, i somehow find a few drives that bring me down haha

Oh these were the days. My DIC average is now around 24mpg, but calculated it's 17mpg.

DIC says 24... guess I have a heavy foot... or I want this slowbalt to acually keep up with traffic... lol ;)




jk

On average I run a combined 26 MPG or 8.9L/100KM but straight freeway driving I get 6L/100km or 40 MPG!!

That is with a 2.9 pulley 42 LB injectors and a Trifecta tune. Oh and a slipping clutch.....

Well I drove to Cape Cod averaging 67/68mph the whole way and got 35.6 mpg :)

Normally I'm low 30s or high 20s depending on how much I play.

2.0 LSJ Intake Mod, headers, exhaust, B & M.

22-27 depending on my spirited driving on the tank.

Cruising longer distances I always get 38mpg ALWAYS

DIC stays 32 but I never reset it.

DIC is telling me I'm +/- 37mpg depending on how hard I push it. Just filled the tank yesterday and my own math came out to just under 34mpg. Mix of city/highway as half my daily commute is city streets, and the other half is a 65mph cruise down the freeway.

'06 Cobalt LS sedan, bone stock.

Edit: 5-speed manual.

I own a 2009 cobalt tc with only gm stage II update to computer with cai. Just drove from baltimore to budds creek for the import vs dom drag race. Normal driving, some wot runs on the highway, and a few stops in traffic idling waiting to get in parking lot of race track and leaving. average was 30.2. :twothumbs

lsj... all city, refilled my tank and calculated (not using the dumb epa thing on the dash) by miles i drove / gallon, and im getting 25. and i beat on it all the time

stock lsj 70% freeway 30% city, car out of alignment; 30 mpg.
stock le5 80% freeway, 20% city, 32 mpg.

i get 28 mpg with beating on it everyday.

LSJ TB lowered economy some

i can get to thunder bay and back on a tank of gas and still have some left for around town. . .so 40mpg in my 2.2. which i think is pretty good. thunder bay round trip is just over 400 km

Love how you guys don't even include the LAP...

My SS Balt's stock and I'd say i"m doing 26 mpg average @ 75- 80 mph. I do a lot of highway driving down here in Fla... Plus imma WOT kinda guy lol

The what?

Update on mine, still averaging 34-35mpg around town.

Relatively beating it in downtown Chicago traffic I averaged 30.4 mpgs and averaged 35.2 going 80mph coming back home, mods in sig. :)

I average just over 34 MPG on my work week. Drops down a bit when it is the weekend, cant help it.

i been around 37 for a while but now im down to about the mid 35's, hopefully its just the time of year.

05 Base
Highway is usually around 36-38
City is 28... on a good day!
Last month I realized going 55 MPH instead of 65 can make a HUGE difference. ;)

if you get on I-90 at 55 you'll be road pizza before you get too far.

True. ;)
I tend to take the back roads!

set a new record. 35.7 mpg. for me
