Is it too late to switch to synthetic?

[BustnJustn@aol.com]

Hi all,

I own a 90 V8q with 117k.  The PO was very meticulous about the maintenance of
the car, however choose to use dino rather than synthetic oil.  I have used
synthetic exclusively in every car I purchased new, and have never had a
problem.  I have been informed that by switching to synthetic in a used car
that it will create leaks as the synthetic is slipperier than dino and will
seep through the seals.  I would like to switch to synthetic but not at the
cost of leaks.  Can any of you dispute or verify the information that I
received?  Any BTDT's?

Any information would be appreciated.

Thanks in advance,
Justin
