As for the oil pressure scale maximum number, it won't ever get above about 120-125 PSI as that is when the oil pump pressure relief valve opens (bypass mode). The display is optimized for the expected min/max ranges.
Funny thing is, I do have a 150 PSI sensor on the engine.

I run Mobile 1 0w40.
The 275F reading was from both a track day and 2 hours of driving at 75 mph on the highway. It only takes about 12 miles of driving at 55 mph to see the temp raise to 120F on a 75F day.
