Is it because on average, the shifts tend to be at a lower engine speed with AT vs. MT?

Or does the AT model have some additional cooling capabilities built in?

High oil temps with primarily the MT is a pretty significant data point.
I'm not sure that constraining the temps to the MTs is an accurate assumption. My 6MT has only hit 245 once and that was after spirited driving followed by gridlock traffic for an hour on an 80F day. Otherwise, we've had 70F weather and my temp hasn't gone above 220 even with aggressive driving. As someone (semtex or wstar) said earlier, the temps seem to be settling down a bit as the engine is breaking in. Perhaps initial engine friction is gradually being reduced with the added engine hours. I also did my first oil change with Nissan Ester Oil at 1300 mi. I'm at 1500 now.
