6.7 Cummins Engine Oil Temperature?

Thanks for the replys. Yesterday climbing the grade heading south into flagstaff at 65mph with a stiff headwind grossing 21-22k with my high profile 5th wheel and 100* ambient temps engine temp hit 220 and oil temp hit 246. I wasn't worried about the engine temp since the fan was roaring and it cooled down quick once the road leveled out. But I had never seen the oil that hot.
