Mobile site doesn't follow a car's 'units' setting
 

The mobile site doesn't honor the Litres/Gallons setting in the car's profile. I did a 31 litre fuel-up on m.fuelly.com, but the main website says 31 gallons (117 litres!). All of the fuel-ups I've done from the mobile site (all three of them) had the same problem.

Sorry about that, the problem has been fixed up. But you'll need to go in and either edit those three fuel-ups to correct the numbers, or remove and re-add them. Sorry again about the trouble.
