The House approved a bill on Wednesday that permits the year-round sale of a gasoline blend containing 15 percent ethanol, known as E15.
The vote was rare in its bipartisan support, with members from both parties backing the measure despite opposition from Republican hard-liners and some oil refining companies.
Supporters argued the legislation would lower fuel costs for consumers and reduce reliance on foreign oil.
Critics, including some oil refiners, raised concerns about potential damage to older vehicles and engines not designed for higher ethanol blends.
Environmental groups remained divided, with some praising the renewable fuel source while others questioned the emissions impact of increased ethanol production.
The bill now moves to the Senate, where its fate remains uncertain amid ongoing energy policy debates.
Proponents of E15 emphasized the fuel’s availability as a way to stabilize gas prices during peak summer driving months.
The legislative push reflects broader efforts to expand renewable fuel mandates across the transportation sector.
