— Since Sept. 29, diesel fuel sold in Minnesota requires a 2 percent biodiesel blend. And since the law went into effect, the fuel seems to be clogging some trucks’ fuel filters, leading to companies outside the state telling their drivers not to refuel in Minnesota, according to Transport Topics.
Diesel fuel experts cautioned that the same problem could occur wherever biodiesel is used. Bio-diesel is made from soybeans or vegetable oils or fats and contains no petroleum derivatives. “We’ve had some reports of clogged fuel filters,” said John Hausladen, president of the Minnesota Trucking Association in a report published by Transport Topics.
