How stupid do you have to be to drive a car with the oil light on??
Oil light is on because oil PRESSURE is low, not oil LEVEL.
Could be a faulty switch, but if it is anything else ( oil and filter not been changed for too long, wrong grade of oil used, faulty oil pump etc.) you will wreck your engine.
If the pressure is low you will already have damaged it.
Lets see, £50 to have a mechanic check it and do an oil change, or the cost and inconvenience of getting your broken car dragged from the hard shoulder and a new engine fitted, your choice.
