Mine is an E46, and they had engine bearing issues. BMW asked Castrol to do some Investigation.
Anyhow, Castrol developed another 10w60 but this time with a higher shear strength which was able to cope with the tight tolerences ad 8k limit of the highly strung S54.
So they have two 10W60 oils, one especially formulated for the S54.
