Here's the summary graph from the various tanks I tested. As you can see, two of those achieved around 600 miles/tank during a roadtrip, while most were around 475. In any case, the trip computer was always estimating high. I merely applied the avg MPG thus far in the tank to the remaining gallons and came up with a much more accurate estimate. So now I'm done with this and will focus on something else to graph



Here are the details of the final tank (#16) that I analyzed:
