When you fill up select the menu by pressing the button outlined in red on the lower right, press "more", press "fillup", press the more or less arrows until it matches the amount of fuel you have used and press "done". It learns to more closely match real world mileage if you do this every fillup. Be patient, it may take a while. However, for A,B,A testing it may not have to be perfectly calibrated. We are more interested in a percent of change than mpg. For example, 3 mpg may not mean as much in my car as it would in a big work truck.
