Since this event last spring, I've added an AR Oil cooler (which did practically nothing to help temps) and also meth. Now without meth, temps stay down at roughly 275; but with meth it stays down to 265*

Cheers!
Well this is good news, since I am currently using Mobil 1 0W40, and plan to use it at the track. I previously used total oils for this car, and this is my first time using Mobil 1. So far so good, but the track is obviously the ultimate test. I perviously used total 10W50 (racing oil) for the track, aond 0/5W-30 for the street.

Brian, since you are interested in oil temps, you might want to read up on the N54, and how it handles oil temps (page 42-51)-->

I'm currently using the 1M/N55/335IS water pump, with a non oem whaler thermostat. My cruising oil temps now hover at 210F instead of 245F. However the track will tell if this route is a good way of managing oil temps.
