With the trucker's strike in Brazil people have been lining up to fill up bottles with petrol for their cars and motorbikes where they can. Except that a law was passed in 2008 saying just what sort of bottles are allowed to have petrol put in them.
The ABNT (Brazilian standards association) says the bottle must have the date or lifespan, and be certified by Inmetro (the certification agency). Inmetro says they don't certify this sort of bottle.
Welcome to Brazil.
