RE: [ST] Mobil 1 15W-50 SuperSyn Oil

I have read these oil threads repeatedly over the
winter. And they alway end up with everyone saying I
use this or that and never had any slippage. So my
question is:

Has anyone had a clutch slippage problem that they
think is due to useing the wrong oil? If so what oil
was it?
