DeKALB – Illinois gas prices are increasing with prices reaching an average of $3.94 per gallon. Prices are 11.6 cents higher than last week based on GasBuddy reports. 

The current average stands 31.6 cents higher than the cost last month. In regards to last year’s prices, gas is 39.3 cents lower than the recent state-wide average.

GasBuddy has discovered the cheapest gas in Illinois is priced at $3.29 per gallon. The most expensive gas stands at $4.97 per gallon.

Head of petroleum analysis, Patrick De Hann has said that the increase in prices could be tied to warmer temperatures and a rise in oil prices. 

“Prices are being pulled up not only due to continued increases in demand as temperatures warm, but also pressure from oil prices, which have risen over 20% in the last month, primarily driven by OPEC’s surprise decision a week ago to cut oil production,” Hann said. “Expect the upward trend to continue through much of the rest of spring, but once the transition to summer gasoline and refinery maintenance are behind us, April and May jumps could bring June slumps.”
