My experience post-oil cooler is the oil temp approaches 200 if either: a) heat soak induced city driving, which feels sluggish or b) driving like it's stolen. Other than that, the needle floats between 180 - 195 or lower when cruising on the highway.
However, pre-oil cooler my experience was basically the same as the OP. Oil temps were regularly between 215 - 230 or higher if driving even slightly hard. And I could forget about canyon runs; the temps would skyrocket to the 240 - 260 territory.
