Just wondering what everyone is getting for mileage with the new Pentastar engines? My '11 has 30,000 kms and over the past 1000 kms (620 miles) of driving I am averaging a measley 20 - 21 mpg! My MIL light has been on the entire time and I haven't had the code read yet so that may have something to do with it. I thought these engines were supposed to get 30+ mpg? I wil try adding some fuel injector cleaner and see if that helps.
