for a 528i, shouldn't you be getting more than 24 on the highway?

 

I average 22 mpg. My commute is 25 miles each way, and it takes 14 miles for the coolant to reach operating temperature. If I drive exclusively in the city I get 14 mpg and if I drive aggressively, 18 mpg.

 

2007 530i, get 19 mpg in town, 33mpg on highway at 65 mph. This thing is really easy on gas...

 

While cruising on the interstate I average around 30 I believe. I average 24 combined city and highway. I mostly do highway driving because I work about 20 minutes from home, but I also do a decent amount of city driving too. When I owned my 2009 328i before this, I only average about 23 combined. I don't know if those numbers are normal, but it seem decent enough for me. I don't really drive aggressive much. Maybe 10% of the time

 

2007 525i just hit 110,000 miles!.. City is around 22.8 in the winter and summer to 23.8.. Highway I get around 31.7 to 33.
