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.
