When I hit near 100,000 mile on my car. I noticed that when I started it a "OIL" message appeared right under the total miles (where the miles per tank of gas is). So commonsense told me my oil was low...sure enough when I checked it I need a qaurt of oil. But still the message comes up, I was wondering how to cancel the message from coming up. I understand this is a type of service message but my manual says nothing on stopping it.
