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.
Why is the oil pressure warning light still on?
If you have refilled your engine oil with a new one but the light is still on, the culprit could be the engine pressure sensor. The sensor is connected through a circuit from the engine to the dashboard. With time the sensors get filled with dirt and this reduces their ability to detect low oil pressure effectively.
What to do when your oil light goes off in your car?
Start the engine, and see if the oil light is still on. If the oil light stays off, it means your engine was low on oil.

In some engines, when the oil gets above a quart beyond the full mark. the crankshaft can begin to ship the oil into a frappe, and that can prevent the oil from being able to properly flow through the lubrication channels and perform its function. Oil can ,however, safely lubricate the engine below the “fill” line.

Why does the oil pressure light come on when there is no oil in the engine?
Low Engine Oil Level To create an oil pressure in the engine, the engine needs to pressurize oil. If there is no oil to pressurize, it will be impossible for the oil pump to properly do its job. If your oil pressure light comes on and sometimes disappears, especially when you turn the car, a low engine oil level may cause it.
What happens if your oil level is low?
If the oil is low, it will trigger a warning light indicator on the dashboard, or will illuminate the check engine light. However, since it’s exposed to intense heat and harsh conditions, it can wear out or send faulty data to the engine control unit (ECU).
