in a 2.2/2.4 you'll get sticker gas milage with low end gas...but if you use 93, you can see upwards of 40.


I personaly got 43mpg when driving from IL to CA.

 

Octane has nothing to do with gas mileage nor is a measure of quality of gasoline.

 

I don't see how everyone gets 40-45mpg. Do you actually measure your own mpg when filling op or just go by what the DIC says? Since I always find it to be 2-3mpg off from what I actually get at fill ups on my 07 SS/SC.

 

We all have to remember that the window sticker MPG is an AVERAGE. If you look under the big number it will show a range like 32-42(those are just random numbers) indicating that the vehicle is capable of getting more or less mileage than the big, bold number everyone sees.

agreed when i drove to Kansas City Last year my balt was averaging right aroun 43 miles to a gallon!!!!

 

so how many miles does everyone get in a quarter tank? I have a 07 2LT with the 2.2 and I only get like 64 miles for a quarter tank.

 

On a trip from Denver to Salt Lake my wife was following me in her SS/NA. I was driving the SS/SC. I saw as high as 36 and she said she saw 38. Not bad for the LE5 and LSJ. Gotta love cruise control.

Also, the 5 speed LS and 1LT Cobalts may see 36mpg, but the auto Civics see it too. However, teh manual Civics are worse in fuel economy. Glad to see that the Cobalt is getting better mpg than the little Fit too.

 

ya my 07 ls gets 35-36 on highway if my foots off the gas and i stay in 5th...lol dosent happen often but i was agood boy when i went to cali!no CHP for me!!!!

 

this is ridic how the hell do you guys get these crazy numbers..the people getting over 35...at what speed do you normally cruise on the highway at??

 

whatever the limit is!usually 70-80 unless DPS or CHP(when im in cali) are around the 65-70 mph..lol..im getting 31.3 in city with ocassionaly(i need to learn how to spell)getting on the throttle a bit...fun stuff.

 

i average about 32-33 in my 2.4 when driving regularly.

when I feel the need to open it up more, i get about 29-30

 

it's called cruise control

 

Hrm my balt gets 20 mpg city ... thats after i got it tuned mind you. Before the tune i got 18 mpg city. Pre tune express way was +- 26 mpg. If i try my damndest to get the best econ possable i get 21-22 mpg city but i mean letting gravity pull me down hills, slow acceleration fun factor 0 driving.

 

regardless...diff speeds = diff rpms...plus it aint flat out here hills use a lot of gas lol

im just trying to find out how people are getting such high numbers and i cant break 30

 

I have a 2.2 and can get over 35 easily on highway, sometimes more.

but my average through the week is between 30 and 31 with city and highway.

I'm not sure we can trust the DIC either.

 

I get 33-36 mpg highway!

 

i live in az..the roads are straight and flat..lol i also have no cruise control...im just that good...lol jk

 

I've gotten 33 MPG with my 2007 2.4L with Auto trans.... but that was with some major tail wind on most of the 125 mile interstate trip. recently its been averaging 30 MPG at interstate speeds, up and down the glacial morrains and river bluffs of central and northern Illinois on three separate 250 mile round trips

And the "conditions" are the biggest factor less any drafting.... uphill grades and headwinds will reduce gas mileage while downhill and tailwind will improve gas mileage. Plus cooler temps with high relative humidity will increase mileage.

 

i thought colder temps caused more HP and therfore less MPG

car uses more fuel

 

Well most people that add a CAI get a tiny bit of horsepower and better MPG because the engine breathes more air in since it's cooler.

So that's not really true.

 

took a 450 mile round trip to boston and back yesterday and according to the dic 28.8 mpg
