As ethanol is cheaper than regular gasoline in most of Brazil, most flex-fuel car owners opt for ethanol. Last year, ethanol on average was sold at 59% of the price of gasoline in Brazil, Dutra said.
As ethanol sales keep rising, they are increasingly replacing Petrobras' core oil products, Dutra said.
Petrobras had earlier said that as the consumption of ethanol becomes more dominant, the company will simply increase its overseas sales of gasoline.
But profit margins for exported gasoline shrank due to shipping costs, said Monica Araujo, an oil analyst with the Ativa brokerage in Rio de Janeiro.
"It's negative point also as Brazilian gasoline is of a lower quality than gasoline overseas and therefore has to be sold at a lower price," she said.
The company already now is an exporter of gasoline and heavy crude, but has to import diesel fuel and light oil.
Petrobras said it wants to become a major global ethanol trader, and currently is trying to convince Japan's government to make a 3% blend of ethanol into gasoline binding in the Asian country.
