In the 50i/M you don't measure Miles Per Gallon but rather in terms of Smiles Per Gallon.

I did one early change (myself) at about 5000 mi, using BMW oil. The old oil was slightly darker amber in color but still clear. Was probably a waste given what came out.
IIRC, the dealer procedure actually adds a bit of oil above the full mark (as indicated in the display), and yes this is ok according to BMW...to avoid having to add between changes.
I refilled mine just to the top of the (electronic) range, by trial and error, adding a bit at a time till it was just there. 5000 miles later when the change message came up, it had dropped to about 2/3 from lower mark to upper mark. So I used about 1/3 of a liter over 5000 mi.
