First of all, thank you for taking the Honda hater off. I personally like to see a tank by tank record as it lets anyone studying it know just how you are doing, good and bad. I often wonder if the one entry records just show a very good (or bad) tank. With a tank by tank record there is no guessing. I copy the Insight data a couple times a year and have noticed that some of the one tank records are updated from time to time but still as a one tank record. I wouldn't want to remove the one tank records or the inactive or the sold car records as they are still relevant information. I am going to gas up tomorrow and will update then. Unless something horrible happens it will be two tanks in a row over 100 MPG.....Louis
