I'll bet this low oil pressure is reflecting the high temperature. 230 is not typical. Most owners here will report that the temperature will stay right around 200 most of the time, and a lot of them are running 195 or 192 thermostats. If it were the middle of summer with the AC on sitting in traffic with no airflow through the radiator, then yeah, it might spike up to 230, but even then, you should hear the fans kick on and see the temperature drop back towards 200.
Try a 180 thermostat to start with and see what happens.
