You are half way down (between the upper and lower marks on the dipstick) after 11,000 kilometers?
I'm not sure that you are consuming oil at a rate that even starts to be a problem. How far is that in miles? Seems to me it should be 7,000, give or take. That's not a problem at all. There is absolutely no problem with burning a half-liter of oil over that distance.
