Yes it is, the Castrol is a hydrocracked mineral oil and the Silkolene is a true synthetic, The Silkolene is in a different league.

The Castrol RS 10w-60 and Castrol TWS Motorport 10w-60 isn't the same oil? Castrol TWS Motorsport is extremly popular with Cosworth owners here in Norway. Nobody uses Castrol RS.
