I did my first oil change at 10,000 miles (the dealer did the first one at 5,000 miles).It will take a little moretime to do an oil change on this car due to the numerous panel fasteners (3 Torx T25 in the front, 3 Torx T45 towards the rear section, and 8 additional fastenerswhich require a quarter to easily back out the fasteners). The plug for the oil pan also uses a Torx T45. The oil was very black so I think it is good to change out the oil every 5,000 miles if you want to hold onto the car for a long time and not 10,000 miles as Audi requires. The oil filter wrench that I used on my Jetta fits this car.
I wish Audi would have thought about the car owner when it comes to simple maintenance like the oil changes. They should follow BMW's methodology of having a single door toallow for easyaccess to the oil drain plug. That would have significantly cut down the time to do this job.
