Gas prices rose eight cents in the region but held essentially flat here.

The average price in the region is $3.52 with the price in Warren $3.598 this week, according to AAA East Central’s Gas Price Report.

Warren is now tied with Bradford for the most expensive gas in the region.

The national average also rose five cents this week to $3.19.

“Seasonal demand increases, higher costs for oil, and routine refinery maintenance have pushed pump prices higher,” the report detailed. That’s resulted in a situation where supply demand exceeds supply.

“Oil prices rose after the EIA (Energy Information Administration) reported that refinery oil processing was down slightly from 82.9 to 82.4 percent, signaling that winter maintenance increases ahead of the spring driving season,” the report states.
