Castrol is not a must. Here's a pic of my +180k mile valvetrain, the cam lobe grind lines from manufacturing are still visible.
This motor did 100k miles at SII change on BMW oil (Castrol) and +80k at 60% SII change on Mobil [1] 0-40 EuroCar Formula.
Motor still pulls like new, people have commented they can't feel/hear it idling, inside and in front of X.
Disregard date on pic, it was taken last week. Did not reset date on camera.
