How often to change oil?

[madmods]

Those Q's shouldn't be allowed to be asked online in all honesty! Anyone concerned with oil change, who don't know when to change it, should really speak to a track/team side support engineer or the team manager if possible. He/she will simply ask you: "tell me how you drive your porsche, and at what outside/engine temp, and I will tell you when to change your oil".

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
