If you're regularly going over 240F and not doing anything about it, say goodbye to your rod bearings.
Honestly, people, search the forums. Get an engine oil cooler. It's one of the first reliability mods you should do if you're going to be canyon running or putting the car on track.

I bet you suggest to only use the black tokyo roki filter too or else it will damage your engine.
100-169F Warm Up Phase, high oil pressures
170-189F Near Operating temps, oil pressures still higher
190-225F Normal Operating Range, oil pressures normalize
225-245F Middle End of operating range for track use, 5% drop in oil pressures
245-255F Upper End of operating ranges for track use, 10% further drop in pressures on 0w20
255-265F Red Zone of operating ranges for track zone, 0w20 starts to thin, oil pressures drop to questionable range.
265F+ Playing with fire on 0w20
Keep in mind the data above is oil brand dependent. Different oils breakdown at different temperatures.
Amsoil Signature Series, synthetic *Onset Thermal Breakdown @ 295*
Renewable Lubricants Bio-SynXtra Super High-Performance Motor Oil *Onset Thermal Breakdown @ 275f*
Quaker State Ultimate Durability, synthetic *Onset Thermal Breakdown @ 260f*
