The engine oil life meters do not actually analyze the oil that's in the motor. The meter must be reset. The computer formulates when it should display that message based on a complex equation that takes into effect miles, temp of the engine oil in the past, how hard you've been driving it, and various other factors. It then calculates when it guesses the oil should be changed. So, if the last person who changed the oil (you perhaps?) did not reset the engine oil life meter, then it would be displaying that message when it thoguht the oil shoul be pretty much used up. I don't know how to reset your individual oil light, but I'm sure someone else here does.
