Oil futures drop for a fourth session in a row

Oil futures fell for a fourth session in a row Thursday to settle at their lowest level in three weeks. Reported comments from Russia pointed to the country's unwillingness to join in on a possible plan to stabilize oil production, U.S. crude supplies rose in the latest week, and a fall in U.S. manufacturing activity raised worries about energy demand. October WTI crude dropped $1.54, or 3.5%, to settle at $43.16 a barrel on the New York Mercantile Exchange, the lowest finish since Aug. 10, according to FactSet data.
