Looking at your Log Book: https://www.fuelly.com/car/honda/acco...inc/176603/log
The fuel-up on the 20th was marked as Partial.
Once marked, Fuelly will not calculate MPG for that fill-up or the next.

If it was marked in Error, simply Edit it and remove the check mark and Fuelly will recalculate MPG for you.

Thanks!

This is possibly the most common mistake/issue with fuelly. Are you working on a "pop up" asking "are you sure you want to add this as a partial fuel up?" or something similar? :)

Yep, a quick explanation of how Partial Fill-ups work. :D

Any reason why partial fill ups are not counted for MPG?

Yes- Fuelly's calculations rely heavily on you filling your tank to the top because it uses the difference from full to calculate fuel economy on individual fuel-ups.
FAQ: Why do I have to fill the tank all the way up every time I buy fuel?

The calculation should be based on the percentage of gals put in car at the time of partial fill up. Ex. I put 17.1gals of gas in, tank size is ~24.2, thats 71% of tank, using the assumption from dealer high of HWY MPG is 19MPG thats 24.2*19MPG = 459.8Full tank mileage. Now take the the 71% of tank that's partially filled and use that mileage as the start mileage, till next fill up and subtract the distance traveled till next partial fill up and divide it by the the last amount of gals put in tank, the 17.1gals.
