I bought a new Audi A5 with a 2.0 liter turbo engine in August 2010. From the very beginning this car has been using in excess of a quart of oil every 850 miles. I have done some research and it appears that this happens to a small minority of their engines. Audi seems alternatively unwilling or unable to solve the problem. They have performed 3 extensive repairs replacing 2 different engine seals-one of them twice. The consumption has now actually worsened to about a quart every 800 miles. Now they are starting to tell me that my consumption is really not all that far from Audi's "minimal acceptable limit of a quart every 1,000 miles". Why does the oil consumption vary so widely in their new engines? Why can't they fix the problems? Why do they act like we are unreasonable to expect the same consumption of all the lucky A5 drivers?
