Another vote for the M1 10W-30, but it isn't major and depends on how/where you drive.
I checked the oil temp in my '04 Camry 4 cyl after driving 80 MPH on hwy 40, AC on, 107 degree ambient. The last 10 miles of driving did not have any hard or sustained grades. I shot IR thermometer on oil filter and oil pan. My oil temp readings were between 225 and 229 degrees. The front of the cylinder head was at 188 degrees and the coolant discharge from the engine was at 200 degrees. The engine was idling when these temps were taken.
