I dunno if you guys do this or im just weird but i have a sedan LS and when i first bought it i was getting 32-35 MPG average but then i put my winter tires on and bam my gass millage went down to 28-30. I've notice when i live my DIC screen on MPG it makes me drive with the shfit light to save gas. Im up to 32.0 MPG w00t above average for my winter tires. anyone else do this :P

 

we've done it with the GTO and have actually gotten it up to 28mpg...not bad for an LS2 V8

 

We have a shift light? where is it?

 

only on certain 5 spd models

 

you know what i mean that stupid gas econ light thingy.

 

I have an auto, but I have noticed that when I leave the display on MPG, I do tend to ease up on the stupid pedal. But coming from a 12-MPG truck, it would take a REALLY bad reading to shock me in this car!!

 

once in a while i go and try to see how low i can get it on a daily drive... but then i also try to see how bad i can get it

 

60 mph today for 20 miles got me 39mpg

 

damm

 

nice. my car seems to like either 60mph or 70mph i get most gains from there. any other mphit dosnt move lol

 

60 mpg, seroiusly, i was trailing a semi and going down hill, i always play that game'' the no boost game"

 

i like to start out reallly fast, reset the DIC, then just coast for like a half a mile/mile... the DIC goes up to 99 MPH and then see how high I can keep it... i had it at about 67 MPG for about 1/2 an hour once, hilly area not really pressing the gas too much..

 

Ive had it at 99 for a good 5 minutes one time......going downhill in nuetral.

 

I don't know what it is but im only averaging 22-24 mpg on the highway and I live in south florida and drive the Florida Turnpike pretty frequently and even if I reset the MPG menu before I get on I cant get it over 27 like I did when I first bought the car. Anyone else having MPG problems?

 

i like to take my dads denali and floor it, watching the instananious mpg gauge to go 0

 

those denalis are fun especially to street race in. I've had my parents' up to 105mph on the interstate. it wasn't even stressin to do it either

 

i drive 112 miles a day in my cobalt ls... 70 on interstate, and between 35 and 45 in town... average around 30mpg for the day...

at 65mph i get 35/36mpg
at 70mph i get 31/32mpg

 

as far as the mpg thing goes.....it depends on how agressive you drive......i had my 06 LS Coupe at like 8mpg one day after racing the hell out of it

 

Meh, I don't even bother checking the fuel econ. MY RX7 sucked down gas like nothing, so the Cobalt is like a blessing on the wallet no matter how hard I push it.

 

That's what I usually get for the highway. That's why I like to reset the gas mileage counters on long trips so I average 37, 38 mpg, but then reality hits as soon as I get off the expressways...

 

I too play the "No Boost" game. Especially in city driving.

Average 25.4 MPG as of this morning.

 

i average about 27 on my 45 mi highway, 5 city drive into and back from work each morning. average about 66 doing that. damn shame the mileage in the DIC is almost always overstated. I have all but 3 tanks of gas i've used in 21500 miles, and all the mileages associated with them logged on a spreadsheet. the DIC consistently rates between .8 and 1.6 mpg higher than actual usage based on mileage/fuel consumption.
