Based on the dashboard meter.. but i have the feeling that i go to gas station more often than my Yaris 2008 RS.. is it the fuel tank difference or it's leaking some where...

On my Yaris, i fill up every 15 days.. now, i m filling up my Micra every 12-13 days...

weirdddd...

Yaris 2008 fuel tank is 42L
Micra is 41 L.
