Each different fuel comes at a different price. These prices depend on the country, and even differ between gas stations.
Scooter owners may decide to use whatever fuel that is cheapest and which is also locally available.
Petrol bans in cities
Shanghai has banned petrol scooters/mopeds and only allows LPG scooters to be used in the city due to air pollution.[2][3] About 190,000 gasoline mopeds were eliminated between 2001 and 2004, replaced by 140,000 LPG mopeds as of 2004, at which time the city had over 100 LPG refueling stations.[3] In 1996 the city's 500,000 gasoline mopeds were blamed for one fifth of the air pollution in Shanghai, so in 1997 the city stopped issuing new license plates for them.[3] In 2000, the city stopped renewing plates for existing gasoline mopeds, so all of them expired by 2008.[3]
