That's a good choice, the only thing is you can only get those from Bm dealer in 1 litre handy fills where I get mine in 4 litre containers, so if I buy three 4 litre ones from Costco I have enough for any top ups should they be needed.
The 10-60 is not recommended for the 4.4 V8 F10 because of the tight tolerances of the con rod bearings, problem being at start up the oil is too thick to penetrate quickly.
