If you go back far enough in ancient synthetic oil history you will find some evidence of increased oil weeping.  Amsoil even admits to it. This was back in the day of poorly machined parts and simple paper gaskets that had a hard enough time containing heavy weight dino oil.  In the modern era of better part machining and gasket materials, the reality is that synthetics don't leak any more than dino.  However, the wive's tales persist.  You will still find "ace" mechanics in Harley shops for instance that swear synthetic oil will cause your roller bearings to skid, along with a host of other maladies.  It's kind of like how some people back in the day still believed the earth was flat long after science (and Columbus) proved them wrong.

Both my brother and I tried Amsoil in our 4-wheeled vehicles many years ago when we were an Amsoil(pyramid-type dealer network >:() dealer.
Gasket seepage/weepage, and increase mechanical noise was experienced in both the Chevrolet, and Dodge trucks.
We used petroleum oil after without issues.

I've run Mobil One in our 2000 FXR4 since we got it...  No problems and no worries...   :2vrolijk_21:

Almost every single bike that comes thru here(along with all the fresh engines) leaves with Spectro oil in the engine, and has for about 15 or so years now.
Absolutely no issues whatsoever.
For the folks that request synthetic, Red Line is what we shelf.
