Took my 2011 auto BGM Cruze LS for a 40 mile trip today and averaged 44.3 mpg. I was pretty impressed. This involved mostly 45 to 55 mph steady driving on generally flat noninterstate with the A/C off and front windows completely open. I've been noticing really good MPG numbers recently as I approach 50K miles (49,748 after today's trip). I wonder if it has anything to do with the wear on my tires (down to 5/32 on the original firestones) or maybe my Cruze is just breaking in.
