Mine is going to have a good mineral put in it then its straight on the rollers for the first startup, 10 mins to warming up then a few hours of gentle running with a medium amount of boost introduced, then it will be the final full load map. All on the same mineral oil.
Once fully mapped on full boost which will prob be about 18psi I will be taking a bit of care with the driving of it for around 1k, then I will drop the oil and put a good semi synth in it.
Each to their own I suppost, the main thing is the way the engine has been built.
