During the holiday my kid came for a visit. This is the 2015 A4 dealer service car we purchased a few months ago with 500 miles on it. It now has 3600 miles where the last oil change was done a 500 miles. The bad news is they still use oil and the good news is they use a lot less so far. Both measured by the MMI and the dip stick the oil is down by approx. 1/8 th of a quart. Although still not to my standards it appears it will not be an issue for every 5000 mile service. Just wanted to give you an update FWIW.
