Thanks motordavid. You are right and when i look at my original post I think I overstated a couple of things. First, I did add a litre, but only because the manual says add a litre when oil indicator (itz electronic)at a min level, while when I bought it, the level (at indicator) was half way, so the car burned half a litre or a bit less, and not the whole litre as I added so I am by 100% off there on the quantity consumed. Second, I checked the bill of sale and the mileage is more like 1400km, even though its still approximately 1k, its 40% off. So its about a liter per almost 3000km. I am also flooring it rather often, not to redline, but often which I believe makes a difference. I thought this consumption is ok for this motor. No? I wasnt actually panicking but just bought a second bottle). I find it entertaining - certainly not ladies car as it needs care.

Also I bought it at a small used car dealer, not bmw si he out in Castrol. I am going to use a local shop that specializes in germans, not bmw dealer as I knkw visits will be frequent and I am not paying $200 per hour unless there is no other way.

Its just the reality how different it is from a japanese car that is a couple of levels below in performance.
