I use the SHIT out of royal purple, and LOVE it. Break in, really not that huge of a process. Few miles, nothing over half throttle. stay out of boost. Stop it, let it sit and cool. Check for leaks etc.

Fire it up drive it for a few more miles, and you'll be good to go. Most people greatly over do their break in process. I've built every motor i've had and have never blown one due to a bad break in.

I used Lucas Assembly lube on my last build. Drove it around the block twice, and said to hell with it and drove the shit out of it. Granted its a B20, I flogged the hell out of it 12psi for about half mile out the highway, and drove it normally for a while, jumped on it again.

Everything is still good. Most don't do it, but after break in, I know its a bitch, but I ALWAYS re-torque my head. Heating then cooling can sometimes have the studs/bolts seating or re-seating, so they'll use a good re-torque.
