After two times of refuelling I did a math of how much the scoot is using per 100 km
Topped up 9.83 liters
of standart fuel for 320 km of driving,
means this scooter uses
3.07 liters of gas for 100 km moderate driving.
I was surprised about how less it uses, because even my previous Grand Dink 150 (carburator) took 3.7 ltrs/ 100km.
