Castrol Power Racing 1 10w40

[Vern0207]

Hi guys, has anybody used this Castrol Power Racing 1 10w40 in their bikes? I want to do a oil change but not prepared to pay BMW ripoff prices. I know the book says 5w40 or 10w40 or any SAE that is JASO MA2.

However Castrol Power Racing 1 10w40 is fully Synthetic, Castrol Power 1 is part synthetic, so which?

Regards
Vern
