As you say Edge sport 10w-60 shouldn't be used. however in 2.5k miles it burned only .6-.7 liters of it.
Anyway What would you recommend for next time oil change? so far I've got 4 Illu cubics left.
Changing by those are OK? I guess?

Those are different oils than we have here, so I don't have much of an opinion on which to use. I do see that Edge Sport 0w-40 is LL-04 certified, and that is not a plus for a gasoline BMW engine in North America, due to our fuel quality. Your fuels may tolerate it. BMW has recommended not using those oils here, so I would stay away from them. Either Edge 5w-30 or Magnatec 5w-30 seem reasonable.

10w-60 isn't an issue in terms of oil consumption, but rather for bearing protection. It is heavier than the oil the bearings were designed for. A heavier oil can withstand higher temperatures better, but a heavier oil does not provide better bearing protection.
