I've heard about this theory, but don't know jack about it. This part doesn't help much:
"The biggest factor is that engine manufacturers now use a much finer honing pattern in the cylinders than they once did."
So is this for only NEW as in new from the factory? If you get an old engine rebuilt, does this, or does this not apply? I guess the honing pattern dictates the break-in, so if the engine rebuilder does it the OLD way, you should break it in the old way? Just sounds like a lot of guesswork to me.
FWIW, when my 20yr old engine was rebuilt, I gave it 1000 miles and a straight 30W per the rebuilder's suggestion. Compression numbers are even and high, and it burns no oil on the street.
And on a new CAR (this guy seems to be mostly talking about bikes), I think the manufacturers do break it in on a dyno, right? That's why some of them are coming with synth already, because they're ready to go. I thought. So while changing the oil early can't be a bad thing, it seems like you've already missed this 20mile window, (not to mention the few test drives it's likely to have been on) and I guess I'd just drive the car normally.
