Springfield, IL (CAPITOL CITY NOW) – Gas prices in Illinois are either unchanged this week compared to last week, or a little bit lower — depending on the agency you ask.

GasBuddy.com says its average price for a gallon of unleaded in Illinois sits at $3.41 a gallon, which did not change from last week.  The AAA report, however, says its gas price average in the state is at $3.43, and has declined.

By and large, gas prices in the Springfield area have increased in the last week based on a GasBuddy price map, with no unleaded prices remaining under $3 a gallon.  Prices range from $3.09 to $3.29.  AAA’s Sangamon County gas price average is $3.245 a gallon.

“With Israel and Iran trading attacks over the past week, oil prices have continued to climb—and gasoline prices are following suit, rising at a pace we haven’t seen since last summer,” said Patrick De Haan, head of petroleum analysis at GasBuddy, in a news release. “Few pumps have been immune, with nearly all states seeing gas prices rise over the last week. Additionally, average diesel prices recorded their largest weekly jump since August 2023. Now, with the U.S. launching attacks on Iran, oil prices are likely to continue trending higher. That said, I do not expect the apocalyptic spikes being circulated by some so-called influencers on social media— many of which are wildly inaccurate. For now, motorists should anticipate a continued steady climb in prices, with the national average likely to increase another 7 to 15 cents this week, while diesel could rise by 10 to 20 cents.”

Gas prices in Illinois are higher than national averages — $3.18 according to GasBuddy, $3.22 according to AAA.  In Illinois, gas prices are 1.2 cents lower than a month ago, and 39.3 cents lower than a year ago.
