Your oil temps should always be above about 180 once the car warms up. Cooler than that and you're too cold for the proper oil viscosity. 240 is a pretty good number for "as hot as you should see without worrying about it" as long as you're not always running that hot. Over 240 and the oil starts thinning out.
At 285, you might as well just pull into the pits and guess which rod is knocking this time.

Many say it's a good idea to keep oil at around the boiling point for water, 210F or so. This makes sure that all condensation flashes out of the oil and out your breather lines.
