I can drive for about an hour or so in mildly spirited (I know, subjective term...) city driving without hitting 4th/5th gear much and see 220 oil temps until I get into 5th for a while or something like that. Never seen a performance impact. Once I stay in 5th a while (usually on the freeway) I'll see the temps plummet.
I've been under the impression that I should be worried if I ever see 250+, but I shouldn't hit that with any normal driving unless I track it.
