I average (60% hwy/40% city) 24 mpg on my 2001 A4 vert that currently has 52,800 miles. I always use top tier premium gas. Have never put in any fuel system cleaners like Techron.

My 04 Mn6 gets over 29 on the highway and over 24 in town as long as I keep control of my right foot.
Thats what I would see when I'm using the instant mpg. I guess I'll drain the tank and add gas and then manually calculate it.
