If it were not for better lubricants and materials engineering, we would not have these highly advanced engines available. 260 deg oil temps are yesteryear. 280 deg are today. I am not going to lose any sleep over whether or not my engine will wear prematurely unless I abuse it e.g. tracking the car. Yes, that's abuse. So protect your engine and get a cooler. Protect yourself and get a roll bar and a helmet, etc. I bet there are some folks in here who think their insurance company should pony up and make good on a claim if by some fluke you write off your car while tracking it! Or lay blame on a faulty part and expect the responsibility lies with Nissan or the race track or whatever to make good on the repairs. Anyway, these threads are still very entertaining.
