I have been avg 23mpg city driving on Eco Pro with the factory oil, sometimes I switch to sport mode to jack rabbit if I feel like it. So far I have been getting around 220-230 miles on a 65% in the gas tank weekly.
Btw, when using the ASS, I felt like it was smoother with the oil change.

Trip cost to a local BMW Indy

Hopefully I would see improvement overtime,
When you write 'factory oil' are you referring to Castrol? The oil BMW uses at routine servicing is exactly the same oil that is used on the production line. The new oil that you used should be the recommended viscocity and specification, i.e. be BMW approved. If not you will likely void any warranty on the engine.
