Where do you measure the oil temperature?

Mine is taken in the oil pan, where it is the highest temperature.

I have seen 260 F. many times, and I consider that normal during climb
and taxi.  I also use Mobil One Synthetic oil, to tolerate the heat.
During cruise it will stabilize at 220F. 

You need to get the oil above 220 F, to evaporate the moisture anyway.
