I assume that it will improve when it gets broken in. Compared to a 1999 Century (17) and my 2003 DeVille (15) it is great. The best thing about the car (compared to Toyotas and other Japanese compacts) is the ride. I don't see much difference from the 2006 Impala I had. Obviously there is no comparison with the Cadillac but for a small car it rides very well. Toyotas are stiff and uncomfortable at least for me. The Yaris is horrible -the front seat doesn't go back far enough. The Chevrolet HHR isn't much better. Very small-feeling and cramped.

Actually -"city" out here (Clovis NM) isn't really city bumper to bumper driving like I had for years in Washington DC. When we were in Kauai in January with a 2008 Cobalt rental car we averaged about 28 in road (50 mph maximum) and small town driving. Around here we probably average about 20 mph with city streets, some stop lights, stop signs etc. It would be like suburban driving elsewhere.

I got 28.8 MPG on my last fill-up for my regular driving.
#202 of 304 33.1 On a trip (but spilled some gas)
Oct 05, 2008 (4:26 am)
I took a 265 mile (each way) trip yesterday and checked gas mileage. The pump failed to shut off automatically when I filled up on the other end of the trip, and a good amount of gas overflowed before I could get back over to the nozzle and shut it off. I was on the other side of the car getting ready to clean the windshield when I heard the splashing noise. The last time I made the same trip, I averaged 33.7 MPG.
I did a little experiment as I drove across I 64 in southern Illinois between the Wabash River and Mt. Vernon. I reset the average MPG on the DIC and drove a steady 70 MPG for 15 miles, and the MPG reading was 32.7 at the end of those miles. I reset it again and drove a steady 60 MPH for about ten miles (had to stop at a rest area) and got 37.5 for an average MPG for those miles.
#203 of 304 Excellent Gas Mileage
Oct 06, 2008 (7:41 am)
I have an 08 Cobalt coupe XFE. The car has 4500 miles on it and the mileage has been about the same for me since mile 1. I get about 30 City and 38 Highway. I got 42 on an 90 mile trip but only once. Most of my driving is mixed so I generally get 34 tank to tank. I calculate mileage manually and use the DIC and find that my calculation is ususally within 0.5 mpg but the DIC has displayed as much as 3 mpg lower. Probably due to where I stopped when I fill.

Your DIC reading is always based on your last hour of driving. So if you did lots of "stop and go" during that last hours it goes down.

I didn't know that! That's good to know, but I would prefer that it just kept averaging from the last time it was reset.

Well I guess my 38 MPG that I was getting earlier is confirmed.....

I can see that it would be possible to average 38 MPG on strictly highway driving, with the speed held to around 60 MPH, which is pretty much what you said your typical driving conditions are.
You should be a happy camper to be getting that kind of mileage.
I have to admit that it was a little hard to believe at first.
#208 of 304 27.9 MPG this time
Oct 20, 2008 (5:13 am)
Weather has cooled off, so the engine is running cold for a longer time on start-ups. I guess that would explain the slight drop in MPG.
Stupid coal trucks! I got behind one this AM on my way to work and heard some fine particles hitting my car. When I got to work and looked at the front end of my car, there were fine particles of wet coal dust. I went to a touchless car wash that probably stripped off the nice coat of wax that I had just put on my Cobalt a couple weeks ago.
I should have known better than to get that close to the back of a coal truck, but I was intending to pass him. It was the two lane road that I travel every day on the way to work. I'll just stay back and not try to pass next time.
