I can't answer your question, but I might be able to help.  I have never trusted these things except that they should move up when the car is running. 
 
Look at a past Thread that I started called "How to turn your odometer into a digital tach."  Read all the replys and go to the link that is mentioned.  If you follow these instructions, I believe you can get the odometer display to show you a digital readout of oil pressure (among other things). 
 
There is one catch.  I know this works on 2000 and newer cars.  I don't know about your model year. 
 
Hope this helps!
