Interesting article...A few months ago I was in northern Argentina in a town right on the border with Brazil. On a sleepy, hot Sunday I asked the cabbie why there were so many cars lined up at the local petrol stations? He told me they were all Brazilians who come over the border to fill up tanks and cans with gasoline. He said Argie "combustible" was a lot cheaper than the Brazilian ethanol blend. Never hear about this stuff.
Interesting anecdote.
