In Brazil as well, which is where I am coming from.

I did not notice a real decrease in refuelling stops, compared to a gas vehicle. But that is subjective, I haven't measured. That might also be explained by the size of the tanks: most 'converted' vehicles retain their ability to be powered by gasoline by flicking a switch, so the tank cannot be too big and has to go in the trunk.

Almost all conversions are done to decrease costs, most frequently by taxi drivers. As you are required to do annual inspections, it drives up the costs and it is only worth it if you drive long distances in one year.
