I've found that if your running harder than normal with high RPM and a hotter than normal oil temp, you will burn off some oil (at least in mine) My observations show that if the oil temp is 110C (230F) I will burn off some oil. I definitely need a oil cooler. I don't like oil temps that are over 100C (212F) and will be doing something about it soon.

For the record, my choice of oil is Castrol GTX 10W-30, just because I change my oil more frequently and can't justify the cost of a synthetic oil with the frequent oil changes.

Autozone is who carries it around here. Also, why change oil so frequently? With a true group 4 unless you are getting fuel dilution or running hot (which it seems you aren't), there is no need. I have even read that oil analysis with a GOOD oil that doesn't sheer shows less wear towards the end of the usage of the oil than the beginning. Again, this is READ, not personal knowledge.

Any oil temp under 280* should be fine from what I have read in the 'vette world. Is there a reason why this is too high in a 370Z?

280 is the point the ECU puts the car into Limp mode to protect the VVEL system. The chances of that happening on the street are extraordinarily slim. Oil temps drop as these cars break in. 220-240 are normal street temps without a cooler. You will drop approximately 25 degrees with a correctly sized cooler installed. If Nissan had not installed an oil temp gauge, no one would be obsessing about this..

Or if Nissan put a 'normal' range on the gauge.
