That would still be considered to be in "OK" temp, not ideal, but OK at least. On top of that, even if I downshift to 5th or even the 4th to rev it up for fun, the oil temp doesn't really jump above 250 F.

Don't get me wrong, I would still prefer to have lower operating temp if possible (200~220). However, ideally, if one wishes to track the car, an oil cooler is must for almost every car I think.

You don't need to push the car; you just need to keep the RPM high and you'll roast the oil within minutes.
