Update your profile to show your car, model, year, maybe mileage.
The Oil Level Sensor is in the front passenger side of the oil pan. Check the wiring, connector, and harness. They have been known to fail. if you are a conscientious owner and perform weekly underhood checks you can simply disconnect the sensor connector (the message should disappear) and maintain the oil level at the proper height - < ==== ADD XXXXXXXXXX == on the dipstick.
Your proper oil fill, with filter, is 7.5 quarts, and that will place the level at the X's shown above.
The oil level sensor is a reed switch in a wand, with a magnetic float/trigger. Oil level drops and the magnetic float closes the reed switch, setting the message. The sensor is about $25 in Rock Auto and can be replaced with some dedicated labor with the car up in the air and the lower air deflector removed.
