(I'm not picking on you, Pat.  It was just your article that brought this to
mind)

I heard that the cylinders of a new engine are not a smooth as they could be,
and that during the breakin period, the pistons hone the cylinders much
smoother.  For this reason, it is best NOT to switch the the synthetics until
after the breakin period (The improved lubricating properties on the synthetics
reduce the honing effect).  And as stated by others previously, you don't want
to wait too long, or there will be excessive deposits throughout the engine.

I switched to Mobil 1 after 10K miles in my Blazer.  After 5K additional
miles, I have only lost a half a quart.
