It is smart to get your oil above the boiling point for water often to get the water out of your oil. Run your engine hard one day, land and open the oil dipstick, watch all the moisture leaving the oil..
I have seen the inside of engines that spent their life with oil temps at 140-150. Lots of corrosion from the moisture in the oil. Moisture is a byproduct of the combustion process..
Guess it depends on the power setting, are you mid 300's at say 2,500 rpm? Are you running LOP or ROP or peak EGT? Also would depend on altitude, higher you go less cooling the air can do. My field is at 5,000 and if I am going somewhere I almost always have to climb to at least 10k.
