Yes, but typically the reason that synthetics aren't recommended during
engine break-in is because they protect the parts too much, not because
they protect too little. The parts need to wear in against each other
and often synthetics prevent this "normal" wearing in process and thus
cause problems later, generally with rings that do not seal well.
I would never use synthetic during initial break-in, but I cannot believe it
caused the problem you experienced, although, I will admit to using only
Mobil 1. I have never been an AMSOIL fan, but that is based admittedly on
the fact that I find their marketing so "over the top" that it causes me
to also mistrust anything else they claim.
