Average gas prices in the region and national levels jumped overnight, AAA Mid-Atlantic reported today.

In the five-county Philadelphia region, the average price for a gallon of regular no-lead was up 4 cents, to $3.91. (A year ago, the average was $3.11.)

South Jersey saw the average go up 4 cents to $3.74. (A year ago, the average was $2.93.)

At the national level, the average price was up 5 cents overnight, to $3.88; a year ago, that average was at $3.23.

Oil prices rose today on worries that supply can't keep up with growing global demand, after tumbling around $4 overnight from a record above $135 a barrel.

Light, sweet crude for June delivery was up $1.49 on the day to $132.30 a barrel in electronic trade on the New York Mercantile Exchange by the afternoon in Europe. Earlier Friday, it rose as high as $133.14 before pulling back.

During Thursday's session, the front-month crude oil contract rose to a record $135.09, but then fell back sharply to settle at $130.81 as the dollar strengthened and gave some investors reason to sell oil futures to lock in profits.
