I just drove my car down to GA and back (~3 hours each way) and most of the time it sat at 220, there and back, in about 85*F weather.

However, when I got into the city I kept the car more in the powerband (between 3k and 5k RPM) for more immediate power (take no prisoners city driving, it's crazy in Charlotte). After about 5 minutes of this my oil was hitting 250. Luckily I was driving right past the Nissan dealer and had them document this overheating. They were clueless of course, saying that it was a bad sensor and they had seen it before. Suuuure...

So I can cruise for hours in 6th gear at 220*F, but as soon as I change gears and run at a higher RPM things start to overheat quickly. This definitely jives with the bubbling oil theory stated earlier.
