I changed my oil right at 5000 miles. Your right, ag4ever, the message stayed up almost all time after that. I drove about 200 miles before resetting it back to normal for the next oil change. Next time I will reset it at 5000 miles when replacing the oil. I'm glad of this feature. I for sure don't like having to watch the mileage for the 5000 miles oil change. I bet there are those that can't remember if they changed the oil at 20,000 or 25,000. It happened to me on a older car.
I took no chances and changed the oil. Later I used a oil change notebook I kept in the glove box.
