Those oil lights come on when the oil pressure drops below a certain PSI. Usually it's about 5-7 PSI. If your oil pressure is actually dropping that far it's a sign that your engine is wearing out. The oil pressure is caused by the oil pump trying to force oil past the bearings in your engine. When the bearing get worn, it take less pressure to force the oil though the bearings, thus the pressure drops. But, the good news is, it might just be a bad sending unit for the oil light. I guess I would have a mechanic put a mechanical gauge on the engine for test purposes and see what the actual pressure is. Hopefully, it's just the sending unit, good luck.
