Oil temps of 220 are normal in the summer. Coolant temp can get to the upper 220s in low airflow before the high speed fans kick on. With coolant temp this high, oil temp will follow. Even on the freeway when coolant temp may be down near 195 or so, oil temp will typically be 20 degrees above coolant temp, particularly if you are using a lower gear, say fourth or fifth instead of sixth.

Personally, in my car which sees only track use, I change my oil every four track days.

I've read that around 300, the oil's life is measured in hours, which is probably one of the reasons race teams change their oil every race.
