The average price for a gallon of gas in Pennsylvania is 7.6 cents higher this week at $3.372 per gallon, according to AAA East Central’s Gas Price Report.

Oil costs hovering around $80 a barrel have helped push the national average for a gallon of gas 5.5 cents higher since last week to $3.126.

Global oil prices have surged due to strong winter heating fuel demand and new U.S. sanctions against Russia’s energy sector.

Oil costs account for 56% of the cost of a gallon of gas, so more expensive oil leads to more expensive gas. However, there are still 25 states with averages below $3 a gallon.

Today’s national average for a gallon of gas is 8 cents more than a month ago and 4.8 cents more than a year ago.

According to new data from the Energy Information Administration, gasoline demand fell from 8.48 million barrels per day last week to 8.32.

Meanwhile, total domestic gasoline stocks rose from 237.7 million barrels to 243.6, while gasoline production popped last week, averaging 9.3 million barrels daily.
