It is as simple as that. I believe any decent race team or aware track car owner knows that oil should be flushed after each track day/race.

You could translate and apply this into your daily driving. E.g. I would change my motor oil if I would be stuck in traffic for more than 1 (one) hour during a very-very hot summer day for instance. You shouldn’t need to rely on your little km gauge to judge whether you need to change your oil!

If anyone haven't understood the concept of modern "oil" until today, I'd just give up trying to find out and suck on what porsche "generalize" in their (thank god) User manual

You've got to be kidding me.... Your just ridiculous... Like these aren't race cars sir. I feel that none of us have race team managers... And aren't strictly racing...

And you're wrong... He would ask you how often you drive on the highway, the street, and on the track.... Because these each run in a general range of oil temps... If you want to get all technical, you should probably know what you're talking about. NOT RACE CARS.... Thats like asking a proffesional drag racer how often I should do a motor swap....

To end the discussion:
Do an oil change as often as you can afford but don't let it get out of hand.
Around 5k miles is generally safe.
More than every 3k miles is exessive and you're just wasting money.
Don't go more than 10k miles, especially if you haven't done an IMS upgrade.

I believe that fully concludes everything people have said.
