thanks guys. I'll try a Bmw NON dealer repair facility here in AZ. I agree should be a TON cheaper than the dealer.
I got an app for my Android phone in the meantime that converts l/100km to mpg. Its not exact, but it give me a general idea.
Cruising on the freeway, and playing with the cruise Up or down. If i go about 63 mpg on level ground I got it say between 6.2 and 6.8 consistently which is awesome! :driving:
