Spot contracts for light sweet crude slid $1.62 to $54.02 a barrel on the New York Mercantile Exchange, and earlier in the day hit a 19-month low of $53.53. With the drop, oil prices are now down 10% in 2007. Heating oil fell 3 cents at $1.53 a gallon. Gasoline shed 4 cents at $1.43 a gallon. Bucking the trend was natural gas, which rose 13 cents to $6.76 per million British thermal units. The U.S. Oil ( USO) exchange-traded fund slid 4.2%. The PowerShares DB Oil ( DBO) fund was down 4.2%. Weighing on the sector was news from the Energy Information Administration of rising energy stocks. Gasoline reserves were up 1.8%, while distillate fuel oil inventories rose 4%, in the week ended Jan. 5, the EIA said. Crude inventories actually fell 1.6%, but that wasn't enough to stop prices from dropping. The EIA said that bigger factors were at hand. "
