Like Winter Temperatures Illinois Gas Prices Dip

Illinois gas prices have decreased 2 cents from a week ago. Today’s state average for a regular gallon of gas is $3.04. The price of gas is 29 cents less than a month ago, and 38 cents less than this time last year.

“Now that the holiday season has come to an end, fewer Illinoisans are filling up at the pump,” said Molly Hart, spokeswoman for AAA – The Auto Club Group. “Gasoline supplies are strong right now, due to strong refinery activity so barring some unexpected shock to the global oil market, gas prices will likely shuffle up and down a few cents for a while.”

Since last Monday, the national average for a gallon of regular gasoline has decreased by 4 cents to $3.07. Again, one reason could be lower demand, as fewer people are fueling up after the peak of holiday road travel. According to data from the Energy Information Administration (EIA), gas demand nosedived from 9.17 to 7.95 million barrels a day last week.

Meanwhile, total domestic gasoline stocks increased substantially by 10.9 million barrels to 237 million barrels. Weak gas demand, alongside increased supply, has pushed pump prices lower. However, rising oil prices have limited price decreases. If gas demand remains weak, drivers will likely continue to see pump prices trickle downward.
