I was wondering at what mileage you all saw the biggest bump in fuel mileage and how much in your A3s? We've seen a steady incremental increase in fuel mileage (maybe .5 mpg here and there), but the tank after turning 13K miles, we saw about a 3 mpg increase in fuel mileage driving over the same commute route.
