With me getting a nice average of 27mpg since calming down a little I think Im doing quite well.
Strewth, I can do much better than that in my mighty RS4 !!!

Bloody hell TT, 27mpg from an RS4, what you doing!? Pushing it and letting it idle
I rarely get above 25mpg in mine 
It is actually reasonably easy to get an average of around 32mpg from my RS4, whereas with my last S4 (same engine capacity, but less ponies and no FSI) I really struggled to get 27mpg. What really helps, appart from the FSI, is the fact that the large 4.2 litre displacement provides absolutely masses of torque from nigh-on tickover (90% of the total 430Nm is available from 2250rpm). If I just left it in sixth gear, it can trundle along at 20mph (without any driveline shudder), and go all the way upto 170mph - how many diesels can do that?

If you read my sig though, you will see how low I can get my RS4 - last year in Germany, on a long high speed run with a few v-maxes, I emptied the 63 litre tank in just 110 miles!
