Oil prices slip Monday

NEW YORK, Aug. 11 (UPI) -- Crude oil prices wavered Monday, closing at $114.57 per barrel, 63 cents lower than Friday's closing price on the New York Mercantile Exchange.

Prices fell as the dollar gained strength against the euro.

"If the dollar continues to rebound, we'll see even more of a drop-off in commodities, including crude," Matt Zeman, head of trading at LaSalle Futures Group, told The Wall Street Journal.

Other energy prices were mixed Monday. Heating oil rose 0.004 cents in late trading to close at $3.1235 per gallon. Reformulated blendstock gasoline prices rose 0.0059 cents to $2.8725 per gallon. Natural gas prices fell 0.061 cents to close at $8.41 per million British thermal units.

The national average retail price of unleaded gasoline fell 0.008 cent to $3.81 per gallon, the AAA Daily Fuel Gauge Report said.
