This is the factory fill for my BMW 135i. I have also pasted the VOA of BMW 5w-30 high performance synthetic for reference, though it is not necessarily the FF (though other than the Ca, Id almost say they were identical). Note the fuel dilution and viscosity loss at such a short interval. It should be doubly noted that at least 1000 miles of this was sustained driving at temperature, with the oil at temperature, which was 250-260F. The car has returned between 26-33MPG during this time.
The TBN was retained fairly well and the wear did not really suffer, IMO, considering the wear rates for the factory fill at 1300 miles compared to what I have seen and posted as UOAs for breakin oil change results from other vehicles. I have not touched the AF, and I assume the Si is due to gasket materials. I can't say this is very bad, and I will be interested at a longer OCI result when I take one at somewhere around 5000-7500mi.
Oil changing on the car is super easy, though I do miss the dipstick because it would make it easy to use an oil extractor to take a UOA sample in the interrim to track wear rates, etc.
