During a live broadcast of AgriTalk Wednesday morning, Ron Lamberty, ACE vice president/market development, shared the results of a pilot study ACE commissioned on the fuel economy of ethanol.
The study involved researching the fuel economy, cost per mile, and driveability of various blends of fuel including unleaded gasoline, E10, E20, E30, and a specially denatued blend.
Three late-model, non flex-fuel vehicles were tested using each type of fuel.
E10 was less expensive per mile than unleaded gasoline, according to the study.
The higher the concentration of ethanol, the lower the cost per mile.
Simply put, on $20 worth of gasoline, a drive can go up to 15 miles farther on ethanol-blended fuel than on straight unleaded.
The vehicles averaged only 1.5% lower mileage with E10, 2.2% lower mileage with E20, 5.1% lower mileage with E30, and increased mileage of 1.7% with the specially denatured blend.
If drivers want to save money at the pump as gas prices reach new record highs, this pilot study confirms that ethanol is the fuel of choice, Jennings said.
