But there is oil in there
The light means the oil pressure is low, not necessarily that the engine is low on oil. It could have low oil pressure, or the pressure switch could be faulty.

This could be two unassociated problems; the flickering oil light can indicate that the pressure sensor for the idiot light is failing- this is not uncommon, the other can be a failed temperature sensor sensor on the main radiator.
The low oil pressure condition may also be indicative of a worn engine part or parts.
It would make sense to have the actual oil pressure checked in a shop to see if it is in the normal range which should lay between ~30 & 60 pounds depending on engine RPMs and engine temperature.
The idiot lights trigger at around 4-5 pounds and this is really pretty late for a warning; if the pressure is actually that low, not only lubrication is too little but the cooling effect of the circulating oil is inadequate.
If it was my car, I would replace both sensors before getting too worried.
The cost of these together (parts only) should be well under $50 US.

First pull dip stick and smell oil. If it smells like gas or if needed change it. If that does not solve it you have two options. Do a oil pump pressure test either pay a tech or buy the tester. Or, you can try replacing the oil pump pressure sender (sensor). If it still come on and is only on at idle, then you will be able to drive vehicle, but you have a weak oil pump, which, (in our service center), is not common on your vehicle. If you hear a low level engine knock at idle, then your bearings are worn out and I suggest you nurse this baby to get all the miles out of it before it gets worse. Believe it or not we had a customer with a 97 Olds Cutlass, 3.1l engine, lower engine knock, had internal bearing damage from coolant inside of oil. She drove the car over 20,000 miles before it bought the farm!!!

FOR THE DASH LIGHTS, FIRST CHECK YOUR FUSES, IF NOT ITS PROBABLY THE STALK ITSELF, COMMON FAULT ON THESE.
FOR THE GRINDING CHECK THE WHEEL BEARINGS, AND BRAKES
