Because I once had a Riding Mower fail that always had 10W-30 oil in it and I never monitored oil temps. I had to go get my old Walk Behind Mower to finish mowing the yard. The feeling was absolutely horrible to me. It was also the shock of what happened and also rolling the Mower onto the driveway and then taking it to the scrap yard.

I regural vehicles, regardless of modifications, Porsche A40 approved/specified oil is ALWAYS way to go.
Hyundai warranties their N cars on non sanctioned track days IF it is stock, the crash would be on him I bet. This was far from stock, so no warrantry from Toyota. He should of had X-40 to X-50 I would guess, All matters on the oil cooler size and efficiency. What the heck was he thinking tracking 20 weight oil. So Toyota will deny and his insurance company will deny. Depending on model, and his additions, he just lost $50 to $70 grand.

how do you tell your insurance company that one? engine had work done maybe faulty wrenching. regardless for track use should have ran a 5W30

No need for 50 grade.
He was at 254f. I will hit that pushing bit harder, car going up to ski (altitude effect), and I have an overkill oil cooler.
He made a mistake with 0W20. This probably was eating his engine for some time. This was the "grand finale."
The engine itself seems not to be a good choice for the track. There were issues with it.
As warranty, Toyota is refusing warranties on this vehicle even if it was driven faster than 80mph on regular roads. That says everything you need to know.

You don't. He may have had track insurance like Hagerty.
On track, you run Porsche A40 oils. 5W30 in such a small, turbo engine, no way.

You're better than this man.
Vehicle is known for engine problems, this one is tuned with exhaust, cams etc etc and you're blaming the oil without even having the engine town down yet?
20 grade is probably not the best choice for the application but let's wait for tear down results before blaming anything.
270+ deg F oil/240 deg F coolant. VW 1.8 with 115k mi of this at ~400hp says hold my beer every single time. And now it will blow up
I missed that part TBH. I thought it was more stockish. Certainly could be a contributor.
C8 Z51 Corvette.
So the club I'm a member of/do HPDEs with has several Toyotas...Supras and a GR Corolla. From a few convos with the Supra drivers they are running 40 grades. Not sure on the Corolla. I know the twins (86/BRZ) are also 20 grade engines and there are always a lot of those...no idea on what they use. Maybe I'll collect some data on the club's social media with a survey...may be interesting!

Regardless, running a 20 grade at nearly 260 deg F beating on it didn't help this situation but point taken that I missed it had engine/power mods....but those make running a higher-viscosity oil even more critical. I know many VW tuners recommend in their tuning info (in addition to specific spark plug recommendations) moving to a 40 grade on the MK7/8 GTIs that recommend 0W20/508 stock when increasing power.

I was referring to regular vehicles.
Yeah, Porsche 911, M2/3 etc. will always do.

that car looks like it does it so much better than the GR270+ deg F oil/240 deg F coolant. VW 1.8 with 115k mi of this at ~400hp says hold my beer every single time. And now it will blow up

Maybe his catch can was full and stopped venting the crankcase, pushing oil out onto a hot exhaust or whatever. Fire time. Many mods on this one.

Thing is something happened to a bone stock one (I think several?) where it windowed the block and oil sprayed on the turbo catching the cars on fire.
