SD conducts ethanol blend test

By | October 14, 2010
South Dakota is currently testing E30 in some of the state's flex-fuel vehicles to compare the cost-effectiveness of various ethanol blends. A test pool of 86 model-year 2009 Chevrolet Impalas is being used to compare the cost per operating mile of E85, E30 and E10. Half of the pool is being fueled with E10 for the entire year. The remaining 43 vehicles were fueled with E85 for six months and will use E30 for the remainder of the yearlong study. Test results from the E85 portion of the study showed the fuel did not improve operating costs per mile.
