my check oil light came on in my 1991 mustang gt auto. i just changed the oil a couple of days ago. i checked the oil its full there are no leaks or smell or noises coming from the engine. the only thing wrong is the light coming on. is this just the sensor if so whats it going to do to the car, the car is my daily driver and i cant get it fixed due to finances, is this going to destroy the engine. like i said there is no missing oil and nothing unusual but the light.
