Hello all. This is my very first post and I figured I'd start off with a question. I just got my 2005 Cobalt LS Sedan about a week ago. The Fuel Economy read about 28 when I got it. Since I started driving I reset it and am only getting 25 or so. It's an automatic and has no mods whatsoever. Completely stock. Wheels have low tread on them and need to probably be replaced soon. Thus far I've only been doing city driving except for maybe 20 miles of highway out of the 115 I've put on in the past few days. First day I drove it for 100. First car so I decided to break it in and go visit friends. Anyway. What MPG should I be getting. It's been fairly hot (high 80's to low 90's) and I've been having AC cranked up. Thanks for any feedback.
