I don' recall that Porsche has a break in specified in the owners manual.
Nor would they specifiy the oil change routine you suggest, which is sometimes done for motorcycles by fanatics such as myself.
They do fill the engine with Mobil 1 at factory and expect you do do same.
Of course, always allow your engine to be a full operating temp before you hammer it. Otherwise, just drive like a regular car.
Good luck!
