The head of a top fuel industry group wants Congress to take action that he says would protect consumers by keeping a more corrosive blend of gasoline off the market.

American Fuel and Petrochemical Manufacturers (AFPM) President Charles Drevna told The Hill on Monday that a U.S. Court of Appeals of the District of Columbia decision last week will put consumers at risk. The court upheld an Environmental Protection Agency (EPA) policy that let gas stations offer fuel with a higher ethanol content.

Auto companies say the higher-blend ethanol fuel is more destructive to engines and is not covered by many consumers’ battery warranties.
