Well this tank of gas is going to be a good one. In the past few days I've had some 90 and 92 mpg runs on my 60 mile commute.
This tank is at ~77-78 mpg and will certainly make up for driving too fast with the A/C on during the last tank of gas!
I'm at 690 miles and still have 2 bars left on the gas gauge.
I have left my "hot air mod" in place, even though the weather has been in the 70's and 80's at times. It doesn't seem to be holding back the mileage at all.
I've been watching the database and hoping that a few more Insight owners would post their tanks so I could see how they are currently doing.
