We do 1000 miles on a good quality Mineral Oil. 500 miles of no boost and no more than 4000rpm, then progressively work up in RPM and boost between 500 and 1000 miles. I actually kept Mineral Oil in mine for longer than 1000 miles, even though it was running full boost and power.

The rings will be nicely bedded in.

It's no good just sitting it on a motorway at one speed and crunching the miles, it needs to see varied RPM, so sometimes change down a gear for a few miles.

My opinion is that the better you run it in, the better long-term service you will get out of it. Competition cars don't really get run in, but then they get rebuilt every season or in some cases every race.
