FORT WAYNE, Ind. (WOWO) — Gas prices in Fort Wayne have climbed more than 20 cents per gallon over the past week, according to the latest data from GasBuddy.

The average price for regular gasoline in Fort Wayne is now $3.65 per gallon, up 20.2 cents from a week ago.

Gas prices are also up 28.6 cents from a month ago and 37.5 cents from a year ago.

GasBuddy’s survey of 201 stations in Fort Wayne found the cheapest price reported Monday was $3.36 per gallon, while the most expensive was $3.69 — a difference of 33 cents per gallon.

The national average is up 3.6 cents from a month ago and is nearly 93 cents higher than it was a year ago.

GasBuddy petroleum analysis head Patrick De Haan said rising oil prices, the continued closure of the Strait of Hormuz and attacks on Russian oil refineries are contributing to upward pressure on fuel prices.

De Haan said the seasonal switch to cheaper winter-blend gasoline could provide some relief in the coming month, but ongoing disruptions could continue putting pressure on prices.
