Chicago gasoline strengthened after BP Plc shut a fluid catalytic cracker for unplanned repairs at the Whiting refinery in Indiana.
The unit is one of two catalytic crackers at the 420,000-barrel-a-day plant, according to a person familiar with refinery operations who declined to comment because the information isn’t public.
