high oil temps. What can go wrong?

[Yakozan]

Reached some pretty high temps when pushing it at the track the other day.
Started to wonder what things can go wrong when running with high temps?
I know my oil can cope with it without any problems. But can the car cope with it?

What breaks on a car when the oil temps get to high?
I slowed down and drove off the track for a cooling spin when I got about 125 degrees C on the gauge.
The oil I'm running can take much much more then that but I didn't want to break anything.
stock engine temp (water temp?) meter hadn't moved from the middle position at anytime. But I don't trust stock gauges.

So what can go wrong?

The optimum running temperature of engine oil is 80-120?C. This is using a 10W50 fully synth. This means that the oil is designed to run in that range. Running below that means the engine isn't up to temperature. Running over that regularly will shorten the life of the oil, causing it to break down and have worse low temperature performance.

What sort of temps were you running? If it was around 130, I'd say just change your oil now.

I'm running 15W50 oil. So It can definetly take the high temps.
Just curious about what breaks on the car. Or is it all go unless water temp starts to rise?
