Oil consumption vs F10 M5

My F10 M5 was delivered at the end of March, 2012. Here at Hungary/Europe BMW uses Castrol Edge 5W30 or 5W40.
During the first 2300km I had more than 0.75liter oil consumption with normal brake in drive.
I have changed the oil and oil filter at 2.300 km, and switched to Motul 300V Power 5W40. Between 2.300 km and 4.900 km (spirited and sometimes hard drive, but no more than 190km/h were included) the oil consumption was 0,3liter. With Motul 5W40, the oil consumption is less than Castrol Edge, however there is some. The egnine and hone was designed to support better oil filming, but as a sideeffect it has much stronger oil consumption.

On a side note: i also have an e92 335i (N54). With Castrol Edge 5W30, my oil consumption was almost 1 liter during my oil change interval (10K), but when i have switched to Motul 300W Power 5W40, my oil consumption was almost zero up to my 7K-10K change intervall.

On my F10 i plane to change oil every 7K when using Motul 300V as this kind of oil has more limted lifetime than longlife oils. But on the other hand it does much better for my engine.
