Dennis Haynes is probably the most thoroughly oil-knowledgeable
person here; but the only potential difficulty I've heard of (other
than break-in issues, not your problem) is that if seals are inclined
to leak, the synthetic may not keep them swelled up.  I don't recall
anyone coming up and saying they'd actually experienced such a thing
on a WBX engine, and if it happened I presume going to a blend would
take care of it.  Here in New England the 15W50 synthetic certainly
cranks easier in cold weather.

Yours,
