What is your question?
The oil pressure light works ok. In the past the oil pressure reading in the DIC was approximately 50-70. Now it is 90-120 and still says normal. The car seems to run ok. What is the proper pressure reading supposed to be? Thank you.

50-70 is a little high but 90-120 is too high. Put a test gauge on it and see what the pressure really is. If it's really that high, then the oil pressure relief valve is stuck and the high pressure will damage the engine bearings and who knows what else. If it's relally 35-50 or so, then the sending unit is failing. You need to check this out becuase too high oil pressure is a problem.
