You MUST get some power down if you want the rings to seal...
The key is remembering that whilst yes you want some power behind the rings, you mustn't allow it to get hot, because things will be "tight", you want to allow the power, but don't just sit holding it on boost for 10 mins, things will get very hot, very quickly and damage components... Nor do you want to sit on the motorway at a constant speed, it won't bed the rings in, and you've only got one chance to do it... Once the bores are all glazed up, you're stuffed!
For the first 10 minutes, obviously allow it to idle and give it a few revs etc, top up coolant etc... Take for a very quick drive, very short squirts of power to allow oil to warm, drop the oil. Stick some new stuff in, go out, drive about, allow a bit of power, probably let this oil last for a few drives, then drop it. Then put in some decent stuff and really start building the power for longer periods, once you think you're happy with it and you think it's reasonably bedded in, drop again and start whatever service intervals you're thinking of.
Don't use the cheapest crappest oil money can buy whilst running in, just some usual semi 10/40 5/40 will be fine.
