I wanted to understand how to best achieve the highest fuel efficiency on a E89.
I have my mind set on this car due to it's beautiful styling... every time I see one parked I slow down to stare and dream.

I would like to close this thread, I have the answers I seek now.
Thank you all for your input. <3
