The thing here in Brazil is not so much about price, its more about what gas station you can trust, as they adulterate the gasoline. Last week I used Ipiranga on Nove de Julho, Jardins and my car runs 1.5 km more on the liter than normal, but the gas is also more price!
Most important in this crazy city at what PRICE PRICE PRICE? But take a look @ http://www.zap.com.br/imoveis. Great, green, good schools and safe(or safer than Morumbi at the moment) area Alto da Boa Vista!
