I have a relatively fresh motor for, well, the first time.

The manufacturer suggests I keep that motor under 4k rp for 500 miles, and then under 6k for another 500 miles.

This guy says something completely different - some moderate load runs at varied rpm, some cooldown and then more of the same with more throttle, change out your oil-and-metal-bits soup and you're on your way.

Anyone prefer one over the other?
