Eye In The Sky

I've got a new Accord and my custom when buying a new car has always been
to change the oil at about 1000 miles. No doubt that's a hold over from the
bad old days when you had to get the metal chips and debris deposited during
the sloppy engine manufacturing process out of there. Unnecessary today I'm
sure with improved manufacturing-- but I was going to do it nonetheless.

But the owner's manual specifically says not to change the oil early the
first time. Why is that? Is there some kind of special "break in" oil in
there?
