Gas prices fell a penny in western Pennsylvania this week though the price in Warren held steady at $3.599.

That’s 20 cents higher than the regional average which came in at $3.93, according to AAA East Central’s Gas Price Report.

Warren’s rate is back on top in the region.

“After remaining relatively stable over the first few weeks of the new year, the national average for gas edged higher by three cents this past week to $3.10,” per the report. “Even though demand is lower, slightly higher oil costs are causing gas prices to increase.”

Gas demand dipped while stocks increased.

“Due to fluctuating oil prices, lower gas demand, and rising stocks, pump price increases have been limited,” the report states. The price of oil rose after the Energy Information Administration reported a 9.2 million barrel decline in commercial crude stocks.
