When I used 10W60 in my S50 the oil temperature got up a bit since it takes more energy to pump it round. That said the engine obviously is engineered for a lower grade so I would stick to 5W40 although there are enough people using 10W60 (on tracks) and never have problems.

Most important is:

Good quality oil (duh..): Motul, Mobil 1, Castrol, Shell Ultra etc.
Reduce service internal to a max of 12.000km/7500ml
Stick to a max of 2 years interval.

Oil degrades rapidly after 2yrs/12.000km. And more important than viscosity is the amount of pressure the oil film can handle. I know Motul always has quite a good value for this rate.
