Actually glad to learn that it's in the tune, and honestly 285F for me is a good time to call it off, even though the oil can certainly handle temps that high. That said I don't expect it to get to 280F during extended lapping sessions..
the issue with hot oil is oil pressure. Not the oil breaking down. Something is seriously wrong with your oil cooler setup, if you’re seeing temps that high… fix the issue instead of creating moronic workarounds
