BMW 5W-30 is not Castrol Syntec as far as I know. It is apparently Castrol Softec TXT, based on the specifications, but I don't think we know for sure. It was rumoured to be Syntec in North America, since Castrol didn't sell the Softec here, but that seems to have been proven false.
Castrol Syntec is a full synthetic. Castrol Syntec Blend is not. Your post sounds like a Mobil 1 advertisement.
Where are you? Your oil suppliers likely have different oils than North America.
