DO EXACTLY AS THE LINK SAYS!
It's probably the best way to run a car in.. And i haven't seen anything to disprove his methods.

For my Motor (Forged, built, blueprinted, yada-yada)
I used Penrite Run-In Oil, for the first 50KM's or so.
Then the recommended oil grade from factory, ofcourse in mineral oil (I used Penrite 20-60W Extra10)
Did the next Oilchange at 500KM's, put more of the 20-60W in.
Next at 1500, and went to Synthetic.. Which you can use whatever your prefered brand/weight is.

Assuming your Tune is still correct and valid, you should be able to give that Motor the thrashing of it's life after as little as 100KM's.
And as far as 'VTEC' goes.. Hit it.
