Often older cars with some internal engine wear suffer this problem when the
engine is warm at very low RPM's.
The oil pump has worn a tad, and just does not pump like it use to. The
main bearings have worn a tad too and are more likely to let oil seep by
faster they the design spec, so the oil does not build up as much pressure
when the engine is not turning the oil pump fast enough.
It's conceivable that the fault is in the sending unit as well....
Solution 1: Fughetaboutit!
Solution 2: Replace the oil pump, and hey while the pans off do the mains
too...
Solution 3: Get an oil pressure gauge and thread it into the hole where the
oil pressure sending unit lives and see what kinds of pressures you have at
different rpms and operating temps.
Solution 4: Solution 1 with the addition of checking the oil level every few
days **just to be sure** with an ear out for unusual mechanical noises.<!-- ~MESSAGE_AFTER~ -->
