Oil light is not necessarily an indicator of low oil LEVELS, rather low oil PRESSURE. Your problem may be caused by a number of things, and simply adding oil may not resolve the issue.
Check the oil level (properly), and add oil if needed (...properly). If you are still having intermittent oil pressure issues, I would have a Lambo tech verify that the oil pump is working properly. As the car ages, it may be susceptible to continued oil pressure issues that may best be remedied by simply using a slightly heavier weight oil.
As others have said, however, do not drive the car until you have further diagnosed the true issue.
