Yup! Know about this. No matter how I tweak it's still a Lie-O-Meter. Sometimes it's accurate, most times not. That's why I only trust paper/pencil. We drive all over the US, at all elevations, in all temperatures, etc. If we were only to drive locally then it's within reason, but we don't.
Enjoy,

My paper/pencil is a smart phone app named Mileage Keeper. Since I’ve been using it I can view the fuel history since day one of all my vehicles. And I used historical data to tweak the “lie-o-meter.” Haven’t done it on my new F-150 yet because I do not have enough data yet, but on my previous F-150, I was able to get it fairly accurate. Unfortunately, fuel formulations and weather conditions have an effect so I suspect a “ballpark” figure is the best you can get given the circumstances.
