We recently acquired a 2000 Audi A6 2.7t Quattro. My girl drives it and consistently gets 10 - 14MPG city. I have drove it a couple times and while I can get better MPG I am basically driving it like Grandpa. It's winter and I have no garage, I usually do my work in the driveway so I haven't really looked into it much. Any ideas on what I should start with on the 2.7t? I have owned a couple 1.8t's but this seems like a much different beast.

 

I think I might start with: https://www.audiforums.com/forum/aud...t-owner-55914/

 

I get ~13/20 on my 2000 6-speed. Probably age, mild vacuum leaks, worn turbos, low tire pressure?, etc. The car is rated at 15/22 new.
