PITTSBURGH — The average price of gasoline across Western Pennsylvania is 13 cents higher this week at $2.884 per gallon, according to AAA East Central’s Gas Price Report.

Four Mid-Atlantic and Northeast states saw gas price averages jump by as much as a dime this week (Pennsylvania, +9 cents).

However, most states in the region saw a minimal impact following last weekend’s drone attacks on Saudi Arabian oil facilities, with many states switching over to winter-blend gasoline last week.

This blend is cheaper to produce and sell, compared to summer-blend.

This switch had set the stage for a decrease at the pump, which helped ease the effects of increases in the oil and gasoline markets.

Gasoline stocks decreased significantly for a second week, this time by 1.2 million barrels. Total stocks now measure 62.3 million barrels, a nearly 3.5-million-barrel deficit compared to this time last year.

Gas prices in the region may fluctuate in the weeks ahead as the market continues to adjust to dynamics in the crude market.

The average price of unleaded self-serve gasoline in Bradford was $2.959, in Brookville, $2.865; in DuBois, $2.859; in Erie, $2.961; and in Warren, $2.959.

Last week was the first time since early June that the national gas price average jumped by more than a nickel in under a few days. On the week, it’s a dime more expensive at $2.66 with half of states seeing prices increase by 10 cents or more.

However, even with the significant increase, the national average is still cheaper compared to last month (-6 cents) and last year (-19 cents).
