A new analysis by the National Renewable Energy Laboratory (NREL) finds no “meaningful differences between E15 and E10 in any performance category.”

The NREL analysis reviewed 43 studies on the effects of E15 on engine durability, emissions, and other factors, including a controversial study by the Coordinating Research Council’s (CRC). Regarding that study in particular, NREL found “…the conclusion that engines will experience mechanical engine failure when operating on E15 is not supported by the data.”

“The disputed CRC engine durability study has been at the center of Big Oil’s political crusade against E15, and policymakers have been given the false impression that the CRC project is the one and only study that has been conducted on E15. Nothing could be further from the truth,” said Bob Dinneen, President and CEO of the Renewable Fuels Association. The NREL report identified numerous flaws in the study, including faulty leakdown failure criteria, failure to use E10 as a control fuel, and inappropriate statistical analysis.
