According to my 03 Z4 2.5i's computer, I'm getting 27.0 mpg. However, in real world driving (mostly freeway too), I'm actually getting closer to 23mpg (USA). Compared to some people around here, it seems kind of low. Also, I'm curious as to why there's such a huge discrepancy between the actual number I'm getting and the calculated mileage.
Secondly, when I turn on the sport mode on my car, it actually seems to increase my mileage (I think I'm getting closer to 25mpg). Is there any reason for this at all? I'm driving stick shift and I don't drive the car very hard at all.
