Last MPG and Best MPG
 

On my home page for my Smart Fortwo, the Last MPG and the Best MPG are not displayed, but they are displayed for my Subaru Forester. Any ideas?

Your Smart Fortwo only has two fuel-ups and the first fuel-up was marked as partial. When you mark a fuel-up as partial, Fuelly doesn't calculate MPG for that tank and the next one. So you just haven't given Fuelly a full tank baseline to work with yet. You should start getting some numbers on your next fuel-up. There's more info in the FAQ:

How do I account for partial fuel-ups? and Why do I have to fill the tank all the way up every time I buy fuel? are good places to start.

I misunderstood partial fuel up. I marked partial as I did not allow the tank to go to the last bar, but it sounds like a partial is only if you don't fill all the way.

yeah, exactly. If you can't fill to the top, you mark it as a partial tank. But say you drive 10 miles and fill it up, that's a full tank. The thing Fuelly needs to know is whether or not you filled it all the way up.
