On my third day of driving and I am at 23.3 MPG. That is both a mix of City and HWY driving. I'm hoping for the average to go up a little as I have been doing more city driving than usual. But still, 23.3 is not bad at all. My '03 Chevy Impala with it's 3.8 V6 was lucky to hit 24.2MPG. I will post an update later this week.
