Neither are a patch on Silkolene Pro S, which is Porsche approved.

I used both on my old 993tt. The Castrol is RS not RX isn't it? Anyway, the advantage is it gets to work quicker than the Mobil but the disadvantage is its not as long-lasting and so would require an oil change more often than the Mobil. Apart from that, I didn't really notice any difference between the two. If you are willing to wait longer for the car to warm up before putting your foot down then stick with the Mobil. If you want get going asap then go for the Castrol.
