One suggestion to Jason, I think
Please post this when people are entering their data:
Do not post the MPG reading from the dashboard; it is usually a few MPGs high.
To calculate MPG: Miles driven since last fill up divided by the gallons you just pumped to fill the tank.

For anything with a bladder, manual calculation gives you accurate lifetime mpg, but your inidividual tank numbers will be all over the place. And the display isn't always optimistic relative to manual calculation either. For example, manual calculation on my last tank shows 66+mpg while the display display says 3.7L/100km (around 63mpg). I would trust the latter far more.
I think ideally, a correction factor should be calculated based on display vs. calculated lifetime mpg and then the individual tanks are corrected by this factor. That would provide both accurate lifetime and individual tank mpg, right?
