Gov. Gavin Newsom issued a directive to California’s Air Resources Board on Oct. 25, asking the agency to expedite studies regarding increasing the amount of ethanol blended into gasoline.

State regulations currently limit blends to no more than 10 percent ethanol, known as E10, but regulators are considering allowing up to 15 percent, known as E15.
