Oil Pressure

I have a 93 Jeep Wrangler with the 4L inline 6 engine with 137000 miles. Every time I reach 45mph my oil goes to 80 once I reach 50 it goes back to normal and if I drive at 40 my oil pressure is normal. It randomly fluctuates when I drive to between 20 and 80. What is my problem, what should I do?

Maybe a bad oil sending unit-but have to be confirm with oil pressure check and could also be the gauge
