I've only had my 2011 Volt for about 1/2 a year, so I am still geeking out a little bit over tracking fuel burned, MPG, etc... Likely not to the same extent as some others, but I do track it a bit.
I have a spreadsheet with (among other things...) the odometer reading and lifetime MPG. I figured that if I divide the odometer by the lifetime MPG (mile / [mile/gal]) I would get the number of gallons the car has burned over it's lifetime. Pretty simple. Here is the result over time:
I am puzzled by the result... How is it possible that the calculation suggests that my gallons consumed has decreased since late July? I have a suspicion that I know the answer (i.e. the lifetime MPG was reset at some point), but I wanted to see if anyone else has tracked their data similarly and has seen a similar "error" in the calculated lifetime gallons burned.
Get out you calculator watches!
