I agree, you need to get the actual oil pressure checked ASAP--or just buy a new "sending unit" (they are only $10) and see if that is the problem.
The "sending unit" on our cars is just a pressure switch that opens if the oil pressure is lower than 6 psi. That your gauge is dropping to 0 at idle is not a good sign, hopefully it is just the switch...
