S85 What engine oil?

Hello dear forum. I drive, or rather own, since last year an E64 M6 convertible with the legendary V10. The car has only 32000km down and is currently standing with a clutch damage in the workshop. Well, this is not supposed to be the topic here. The car got 22 new oil in the summer. We decided to use the original Castrol Edge. In a video of H2 engine technology to the S85, however, it was said that they do not use this because the additives like to a As the car hardly drives and raw eggs are really durable in contrast to the V10, this is of course relevant to me. So I would like to make another oil change. Unfortunately, I still don’t know which oil is really good for this engine. Can someone help me with experience here? Thank you in advance!
