Hello all. I have recently changed my 2012 A6 for a 2014 as above. The car is in nice condition but it is using a bit of oil. I have done about 400 miles in it since Tuesday this week and already the oil level has dropped quite a bit. My 2012 Audi did not have this problem . Is it because it is a 3L V6 or does this have a potential oil problem? Many thanks
