According to GasBuddy, the average price for a gallon of regular gasoline in Illinois dropped nearly 12 cents in the past week, now averaging $2.89 per gallon. That’s about 35 cents cheaper than a month ago and 34 cents lower than this time last year.

GasBuddy reports prices around the state ranged widely, with the cheapest station coming in at $2.29 per gallon, while the most expensive topped out at $4.29.

Nationally, the average price of gasoline also declined, falling nearly six cents in the past week to $2.79 per gallon. Diesel prices dipped as well, with the national average now just under $3.58 per gallon.

Locally, prices are also trending down, with gas averaging $2.85 in Peoria, $2.73 in Champaign, and about $2.71 in the St. Louis area.

Patrick De Haan, head of petroleum analysis at GasBuddy, says this marks the fourth straight week of falling gas prices nationwide, with increased oil production and strong refinery output keeping prices under pressure. He adds drivers could be seeing some of the lowest seasonal gas prices in the last five years.

GasBuddy tracks fuel prices at more than 150,000 stations nationwide.
