ST. PAUL, MN – Minnesota Commerce Department officials are giving the biodiesel industry another month to fix problems with the fuel that may have clogged fuel filters this winter — the soy-bean-based fuel is blamed for clogging fuel filters, possibly due to high levels of glycerin that gelled in cold weather, according to the Associated Press. A state law requiring diesel fuel to contain two percent biodiesel won’t go back into effect until Feb. 10. To date, Minnesota is the only state that requires all diesel fuel to contain at least two percent of biodiesel. On Dec. 23, the state suspended the biodiesel rule trucking interests complained of problems with engine fuel filters being plugged with black sludge or wax.
