Use the fuel you will be racing with. The process eliminates any issues with too much or not enough oil/nitro etc. I do all my engines this way and have never had issues with break in or longevity.
More oil would also extend the process and when you start to lean the engine out for speed it will still be too tight. That can cause rod and liner issues.
