There was slight movement overnight in the average price of gas, AAA Mid-Atlantic reported today.
The price for a gallon of regular no-lead was down 2 cents, to $1.94, in the five-county Philadelphia area.
South Jersey's average was down 1 cent, to $1.67.
The national average was unchanged at $1.80.
Diesel prices showed more movement: For the first time since April 24, the auto club said, the Philly area's diesel average was below $3, down 3 cents overnight to $2.99.
South Jersey's diesel average was down 2 cents, to $2.67, and the national average was down 2 cents, $2.72.
Meanwhile, oil prices sank today to lows last seen nearly four years ago as more bleak news from the world's largest economy boosted views that crude could tumble below $40 by the end of the year.
After sinking more than $1 earlier in the day to approach levels traded at in February 2005, light sweet crude was trading at $46.09, down 70 cents in electronic trading on the New York Mercantile Exchange by afternoon in Europe. The contract fell 17 cents overnight to settle at $46.79.
"You could see prices testing $40 by the end of the year because the economic data are really ugly at the moment," said Christoffer Moltke-Leth, head of sales trading at Saxo Capital Markets in Singapore. "Demand destruction is still very much the concern."
