Simon,

I recommend you to try Selinna. Personally I find it better than MOBIL ONE, especially the one used by BMW.
My Oil Change History is as follows:
0 - 3000km Stock oil

3000 - 7000km Mobil One replaced in BMW. great difference for the first few hunderd or up to 1,500.

7000 km - 10000km Selinna 10w-60. Much better, the engine is smoother than before. It supposes last more than 5,000km.

10000km to now Mobil One replaced in BMW. Why change oil? Because it is the end of my warranty and I got a free change of oil. Mobil One's impression is good for the one few hundreds. Some technican told me Mobil One is good for the first 3,000km only Mobil One got dirty (yellow) quickly.

By the way, I think MCS should use a better one as the engine should be much hotter than MC.
