Missed fill-up feature adden in 3.1.0.

It's hard to say is it bug. On the screen it looks good (comparing to your min and max fuel economy). I need to take a look at your fill-ups. Fuel consumption was fixed and tested in many ways. It should be good.

Maybe you have checked fill-ups as full even when they were partially?

Please, send me your CSV and tell me what units are you using.

You should have your car's units set before adding any fill-ups.

Do poprawnego dzialania wymagany jest internet. Fuelio zapisuje dokladna pozycje, a internet wymagany jest do tego, aby polaczyc sie geocoderem Google i pobrac nazwe miejscowosci. 

Fix posted to Play Store. 

Settings -> Export -> And me file from /sdcard/Fuelio/backup-db/fuelio6.db.

How did you install 3.1 version? Database schema changes. Maybe you have imported old file. But you should probably know about it.

Could you send me your .db file?

Try to put it on Dropbox or Google Drive and share a link.
