Twice have have gotten 27mpg (calculated, not computer) on my 35i, but it was only on a 100 mile stretch, at night, no AC, on cruise, at 70mph [I'd like to say downhill with the wind at my back, but I don't know]. The same 100 mile stretch during the day (lots of other cars around, so lots of driving game going on), and 100 deg outside (lots of AC), I get about 20-23mpg. A whole tank around town? 14-16mpg. I'm an aggressive driver and have 19" wheels.
Getting about the same out of mine, even in the cooler weather over here. Also, spot on the the imperial gallon (1.2 USG).
