Drivers across Illinois are seeing a sharp jump at the pump.

According to GasBuddy, the average price for gasoline in Illinois has risen nearly 47 cents in the past week, now sitting at 4-dollars-16-cents per gallon.

That’s more than a dollar higher than a month ago and about 77 cents higher than this time last year.

Prices across the state vary widely, with the lowest reported at 3-dollars-38-cents per gallon and the highest at 5-dollars-49-cents.

Nationally, gas prices are also climbing, up about 24 cents in the last week to an average of 3-dollars-92-cents per gallon.

Diesel prices are seeing an even steeper increase, jumping 27 cents to just over 5-dollars-22-cents per gallon — the highest level since late 2022.

Closer to home, prices in Peoria are averaging just over 4-dollars a gallon, while drivers in St. Louis are paying around 3-78, and Champaign sits just under 4 dollars.

Analysts say seasonal trends and ongoing global supply concerns are driving the increase, with the national average expected to reach 4 dollars per gallon in the coming days.

Experts warn there are few signs of prices leveling off anytime soon.
