NEW YORK, March 20 (UPI) -- Crude oil prices rose slightly Friday on the New York Mercantile Exchange, continuing a monthlong trend toward higher prices.
The U.S. dollar's drop, prompted by the U.S. Federal Reserve's decision to buy U.S. Treasuries Wednesday, put further upward pressure on oil prices.
Prices Friday reached $51.22 per barrel, up 19 cents. Heating oil prices rose 0.0349 cents to $1.3834 per gallon. Reformulated blendstock gasoline rose 0.0261 cents to $1.457 per gallon. Natural gas prices fell 0.082 cents to $4.227 per million British thermal units.
At the pump, the average price for a gallon of regular unleaded gasoline was $1.942 Friday, up from Thursday's $1.933 a gallon, AAA said.
