What else kind of scares me is the BMW oil measuring display. You can scroll through it in your info display, but it will only display the level of its last "long count" oil level analysis. I can change oil and leave it 2 quarts down and it will read OK until the customer completes a cycle where the car can measure the oil. Only by going through the computer and holding the BC to reset it can you activate the "short count" to get a quicker reading. Often it will display ADD 1 QUART, I usually play it safe and put 6.5 in before checking.
