Tests Limit Gas Pumps To 15 Percent Ethanol
Minneapolis Star Tribune:
The state’s gas pumps could safely dispense a 15 percent ethanol blend, but no more, according to new tests from Underwriter Laboratories Inc.
That’s slightly higher than the current 10 percent mandated by Minnesota law — a mandate that would rise to 20 percent by 2013 under a law passed four years ago. But UL says it’s not giving a green light for “E15″ gas, which can sometimes contain more than 15 percent ethanol.
The state’s pumps were originally designed for E10, and the capacity of higher percentages of ethanol to cause additional wear drew concerns.
