Not OK to let car idle?

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

I had a neighbor who had a diesel expedition and would remote start it like an hour before leaving for work, it was maddening.
Why is it that truck operators leave their rigs on for hours idling though??

I've known about not idling engines for years, but most people I know believe their cars need some magical period of time idling to warm up... i stopped trying to get into these conversations as they are about as productive as break-in period ones.

Manufacturers have been telling their customers to just drive off after start up since the fuel injection has been invented. There's no need to warm up a fuel injected car. Sure,if you've started your car in 20F weather,you can wait for a minute to let the RPMs drop a bit and then you can drive off.
Now when it comes to letting your car idle : it's not the best to have it idling for extended periods of time,especially when it's done on a regular basis-like a police car or a taxi. That will increase wear on the engine in time. But the concern is not valid for the type of idling it is being talked about here : traffic or waiting at the track. And I don't buy the " lack of oil lubrication " while idling either : these engines have several oil pumps,where at least one is computer controlled according to demand. There's no way these engines are missing lubrication while idling!
Here's a thread I found talking about the new GT3 engine :

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.

I get your point. I don’t believe in idling an engine to warm it up, but if I’m driving my $160k+ 2018 GT3 around town and I pull into a parking lot and want to finish a Bluetooth call with the air conditioning running for 10 minutes at idle before turning the engine off and the engine can’t handle it, that’s plain ridiculous.

I live in TX and I like air conditioning. If the engine blows because I idled it too much, it’s those phone calls that would allow me to throw the car in the trash and go buy a better, more reliable car.

Recently TRAKCAR posted his used oil analysis. He had some fuel dilution and his viscosity looked lower than anticipated. They attributed it to fuel dilution.
Here is some info on fuel dilution and causes. It appears that long idling time is one of the causes, and direct injection engines are especially prone to it.

This is what happens when buyers buy a car thinking they will keep it forever. They get **** and beginning to stress over ever trivial issues which rarely of ever develop to anything. Enjoy the car. It's a Porsche. If **** happens, consider it a price of ownership.

I want to keep purple forever...
30K mike oil change next week. Will Post Blackstone Lab report.
had to add 200cc oil today, first time in a long time.
Interior got soaked at Sebring today, from driving in the rain with windows down

When I first started DE's 20 years ago, I had an instructor tell me not to put my elbow on the window sill because the sweat in my arm would damage the leather...LOL, there are some crazy **** people in the world that will invent all kinds of nutball details to fixate over!
Drive your car and enjoy it!

Also, was reading the official oil change procedure and the engines idle for several minutes at the dealership during each oil change as they have to get the old and fresh oil to operating temp.
I’m going to call my dealer service department and tell them they are doing irreparable damage to the engine during this process. 😛
