The latest decline coincided with the lowest oil prices in eight months. Crude futures closed at $91.80 a barrel Jan. 13 and $91.66 on Jan. 9, according to Bloomberg News — marking the first times oil has finished below $92 on the New York Mercantile Exchange since May.
Gasoline, meanwhile, dipped a half-cent to $3.327 a gallon, also its first downturn in four weeks, DOE said following its weekly survey of filling stations.
