Castrol Syntec Problem(?)

[mma@RT66.com]

I've noticed that my 5000CSQ is leaking more oil than I'm happy with. It has
just 70K miles and here's the interesting point - I'm using synthetic and I'd
started with Mobil 1 - for the last 4/5 changes (at every 5K miles) I'd switched
to Castrol Syntec (mostly because it was easy to purchase at the local Price - 
Costco). It is since the switch that the leaking has started...Coincidence??

Meanwhile in European Car -
There was a blurb a few months ago about Synthoil, where a reader wrote a letter
complaining that the 50K miles with only filter changes was BS (I'd have to
agree that 50K with a turbo would make me very nervous). The reply was 'we've
used this on several cars with great results - no leaks, no wear at teardown...

The 'no leaks' statement got me thinking about what I was seeing w/Syntec.

Comments?
