< I probably speak for many others like me) why
is it smart to wait before synthetic is put in?>
To my understanding the reason to wait is that the synthetic oil lubricates SO WELL that it stops the minor "seating in" wear of the ring set and cylinder walls that is necessary. When you rebuild an engine instead of striving for perfectly smooth surfaces on the cylinder walls you actually hone them out with a special tool that is like mini grinding wheels that puts a "cross hatch" scratch pattern on the cylinder walls. This allows the rings and cylinder walls to wear in together as a set, and seal better. Hope that helps!
