| Low oil pressure? The light comes on as the pressure drops below the minimum level. A cold engine generates higher oil pressure due to 'thick' cold oil. As the engine and therefore oil heats up it thins reducing pressure. Increasing engine speed also increases the oil pressure hense the light goes out.
Also too thin (wrong viscosity) or very old oil can reduce the oil pressure. Could also be an oil leak.
I'd change the oil, check for leaks and then get it checked if no change. Could also be a faulty oil pressure warning switch.
