Are you using the car’s MPG or calculated? The car’s BC has a correction factor which most probably is off. If you go to the hidden menu it’s under number 20. I created a spreadsheet to find the difference between the car’s MPG and the one calculated by me. The car’s correction factor was 1.144 and I calculated average 1.028 after five fill ups. This represents 2 MPG off, meaning the car is reporting 20 MPG while the calculated is 22. I'm going to change the correction factor (menus 20.01, 20.02 and 20.03) and keep tracking it to see if it's the correct one.
