I contacted a guy that owns a shop in the UK and his M5 is at 1000hp stage 2 turbo upgrade and meth injection and full strengthened drive trane ,all stock internals I asked him what oil they use over there and they said 5W40.
If someone can prove a night and day oil analysis I might consider it.
For now I will stick with Molygen and change it more frequently 2-3k tops
