This sounds like you have a bearing clearance that is excessive enough to cause the oil pressure at low engine rpms (when the oil pump’s output is lowest) to fall below the oil sending unit pressure threshold for when the light turns on. That threshold is often in the 7 psi range. I would try missleman’s suggestion for a new sending unit first.

What to do when oil pressure light comes on?

My car has an automatic transmission. When the oil pressure light comes on, the engine oil is loosing oil pressure. I recommend performing an oil change and filter change with a good brand filter.

Driving without the necessary level of oil under the proper amount of pressure can result in extensive damage to your engine.

Why does the oil light come back on when you add oil?

If you add oil and the light comes back on, it means the issue is oil pressure, not the amount of oil. Oil pressure is created by the oil pump forcing the oil through the engine. If the pump fails to function, the engine will not be properly lubricated and running it will cause damage.

When does the low oil pressure light go out?

I have changed the oil a couple of days ago, and I’ve noticed that the low oil pressure light stays on longer than normal. Normally, it goes out almost immediately (<1s) after starting the engine, while it sometimes takes up to 4 seconds now after the oil change.
