The synthetic oil, as I'm sure you know, will not "cause" a leak, but because it flows so much better it will leak out an existing leak faster than the other stuff will.

Actually, that is not really correct either. Many synthetic oils actually mimic the molecular arrangement of commonly used plastisizers of the day namely d-octyl phalates. These plastisizers were/are used in many different polymer components including seals. The synthetic oil actaully will pull them out of the rubber matrix leaving behind mico fissures for oil to seep out of.
You know how I know this? I used to work for Parker Seal as a bench chemist many years ago.
