Re: [Amc-list] Synthetic vs Conventional

["Dan Ritzinger" <danritz@xxxxxxxxxxx>]

My son was told explicitly to NOT use synthetic oil in his freshly-rebuilt 
engine for a period of time - I can't remember how long - for that very 
reason.  The engine builder told him it would take "forever" for everything 
to break-in/seat using synthetic.

Of course, I can't tell you where the builder got the info....
