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?
