This. And it is true for all cars.When first starting the car, I wait until the RPM's come down, then drive sedately at least until that blue light goes off. Regular traffic, yeah, I let it idle for a few minutes until the light turns. If there is a standstill or gridlock, I shut it off.

On the track, this car takes a long effing time to warm up. Even for that blue light to go off. So, I go up and down the access road, until the blue light to goes off before lining up at pit entry. If the wait is long at the pit entry and the car is warm, I shut it off.

Buy $200K Porsche and can't let it idle at a stop. Buy $20K Toyota and you can do whatever to it and rock solid for 200K miles.

Some other forums must get a kick out of some of these shortcomings of the GT3

The GT4 takes like 10 min to warm up- crazy.

The GT3 takes half 1/3 of that time. Once rpms die down I exit me driveway and oil at 180 by mile 4.( and I am in Chicago-cold). I think the GT3 warms up pretty darn quickly relative to other cars

We do?

I can't sit in the pit for 15 minutes. My Depends Undergarments aren't large enough.

I was told at PEC ATL exactly as Murphyslaw states above....don't idle almost at all...drive it moderate until 180 degrees and then as hard as you want.....after hard running let it cool down under less duress..I kinda do this with my air cooled Pcar...

Is the GT3 a car or Faberge egg? My old construction company we’d have both gas and diesel trucks idle for about half their 250k mile lives so thousands of hours on the engines and no abnormal issues.

So, the GT3 engine is more delicate than a Corolla engine or a 5.3 liter GM truck smallblock?

​​​​​​Actually they are way stronger. Did you also spin your diesels to 9000 RPM and corner them at over 1G for hours on end? Probably not. They are engineered for completely different purposes. High RPM-capable engines give up things at the low end... like optimum oil and cooling. Recognize this and you'll get the most out of your machines. Heeding the advice of people who might just know more than you is a strength, not a weakness.

Sure, if we were talking about Formula 1 cars.

I’ve heard this since the Mezger days. Can’t remember why, but made sense at the time.

Like a good old diesel engine, excess idling will glaze the bore and will end up smoking like a chimney.

FWIW, page 89 of the 997 GT3 manual says:
