Study: Your Car Can Run On 20% Ethanol

A University of Minnesota study found that using higher blends of ethanol (20%) blended into gasoline did not cause damage or cause performance problems when used in standard gasoline engines.

Over half the gasoline sold in the US is already blended with 10% ethanol (E10), but higher blends were thought to run the risk of causing engine damage. Higher blends of ethanol, up to 85% (E85), will only work properly in engines converted to accept the fuel.

Using 40 pairs of vehicles commonly found on American roads, a year-long research effort found that increasing ethanol blends from 10 percent (E10) to 20 percent (E20) in a gallon of gasoline provided an effective fuel across a range of tests focusing on driveability and materials compatibility.
