That seems low. Are you running in 6th all the time? 6th can be worse than 5th at that speed.

I want to add that I would get 24mpg combined highway and city driving b4 mods. I just noticed your FRC avatar. So if you only got 24mpg only on the highway, then you should look into changing your spark plugs, spark plug wires, air filter (or cleaning it), and fuel filter. I would do a "re-learn" after all this is done.

I would say it's normal. It depends on the terrain, weather conditions, vehicle loading, tire selection and several other factors. You're more likely to see 30+ driving on very flat terrain at cooler temperatures.
Same here with Twin Turbos but average around 15-16 mpg

The mileage on mine will vary a bit and I have gotten in the mid-20s before, but usually it is around the high 20's, low 30's. A lot of factors come into play, including the weather, traffic, wind, etc.

I just got back from a trip to North Carolina from New Jersey. According to the computer, I got 28.8 mpg at an average speed of 66.7mph for 671 miles. On the way home to NJ, I got 29.5 mpg averaging 65.6 mph. 66.7 and 65.6 mph average= It's nice to have a radar detector. I have an A4 with stock rear( 2.73), Vararam, and stock GY runcraps. Car has 43K miles on it. To me, it was great fuel economy.It will change when I go to 3.42's and a TC, but you can't have everything.
