The AC does help with oil temps, I'm not sure what's up exactly but it is 100% observed since I've got my car, regardless of driving style, AC on = cooler oil temps.
I've not added an oil cooler yet to the stock Nissan water-to-oil one.
Would be interesting to note how much power is actually lost while keeping AC on, maybe around 5 to 10 hp max, I really don't feel much (maybe would on the track though... when I go at some point, only just over 560 miles on mine)
