AAA asks regulators to block higher ethanol blend until effects can be analyzed

摘要

AAA, the nation's largest automobile club, is calling on EPA to reject a petition that would increase the maximum amount of ethanol allowed in gasoline to 15%, or El5. The current blend limit is 10%.rnThe group says it supports alternative fuels but more data is needed on the potential impact of E15 on the country's vehicle fleet. There must be unbiased, objective research to prove that the blend will not damage engine systems and component parts, compromise vehicle performance and fuel efficiency, or increase vehicle emissions, said AAA VP Kathleen Marvaso.
