Some of these bio fuel additives were blocked from coming into t6his country by the oil industry.Also the ad comglomerates had a hand init. Brasil makes a lot of alcohol based fuel additives, but they cant bring them here. BUT we can and do shio refined fuel to these south american countys.While I'm in favor of the canadian pipe line, its being pushed by the special interests to the refinerys in the gulf, so they can EXPORT refined product, at americans expense.
