Dee- Blaming Mobil 1 on excessive engine wear is ridiculous. I don't know about the 2.8L V-6 engines like yours, but Audis have proven to be quite reliable, I'm surprised to read your post. Have you owned the car since new? Was the car's engine broken-in properly? Lack of proper break-in could contribute to the early wear and/or excessive oil consumption. Taka
