Hey all,
So I noticed something "weird" with my Cruze. I usually drive a little over the speed limit and my drive to and from work is about 10 minutes each way. I drive, on average, an hour everyday (excluding weekends). I only have ~750 miles on my vehicle. My question is, what is causing me to have such low MPG? I've seen folks here with MPGs in the 30s and 40s... Yet I average at 22 and peaked at 28. No aftermarket items are installed on the car short of a subwoofer. Any ideas?
Thanks!

You have a brand new Cruze with wide heavy wheels and tires, and a subwoofer, that you drive on short trips exceeding the speed limit....That's what's causing it. In addition to the issue of weather or not your DIC was ever reset.

I only have 16" rims (stock) with the stock Hankook tires. Subwoofer(Rockford Fosgate P3 12") is not even 10lbs, and 5-10 over the speed limit (fastest being 70MPH maybe once a week) I wouldn't think would cause such a drastic change in MPG off of the advertised amount. I don't know what a DIC or whether it was reset. I got the car when it only had, if I remember correctly, 15 miles on it. So nearly 100% of those miles we're by me. Could you help me understand how those factors would impact MPG so much?

My in-town mileage (stoplight/sign every block, lots of stop and go) is somewhere in the low to mid 20's usually. <5 mile trips that usually take 15-20 minutes. If your driving is anything like mine, you're doing what I'd expect.

My commute is similar but I only stop at 3 lights tops.
