BP said Wednesday it shipped nearly twice as much contaminated gasoline as it first reported on Monday—4.7 million gallons—to 557 gas stations in Illinois, Indiana, Wisconsin and Ohio.

The company has recalled that gasoline and replaced it after inspecting its distribution system, said BP spokesman Scott Dean.
