A small group of marketers in Wisconsin, South Dakota and Minnesota are experimenting with blender pumps, offering consumers a choice of several ethanol blends, according to ethanol industry sources. "The pump itself would take fuel from the tanks to create any blend level that you programmed it for," according to Monte Shaw of the Iowa Renewable Fuels Assn. "You might be able to have a regular gasoline, an E-10, an E-20, an E-50 and an E-85. So, you could offer many more products to your consumer with the same two tanks that are already in the ground today," he said in an Iowa radio interview.
