You have a lot of potential in that Audi. I was part of a group that drove some Audi TDI's from LA to NYC last fall. I was in a Q5 that averaged 38 MPG, and the A4 and A6 both averaged 42 MPG.
That's good to hear. I just started caring about how many MPG I can get out of it, but I'm still pretty new to the field so the MPG I'm putting out is still not great.
