PEORIA, Ill. – Gasoline prices in Peoria are continuing to decline, although drivers are still paying significantly more at the pump than they were a year ago.
According to GasBuddy’s weekly survey of 148 stations in Peoria, the average price of gasoline fell 9.1 cents per gallon over the past week, bringing the local average to $4.59 per gallon as of Monday.
Prices in Peoria are now 9 cents lower than a month ago, but remain $1.38 per gallon higher than this time last year.
GasBuddy reports the cheapest gasoline in Peoria was priced at $4.19 per gallon Sunday, while the most expensive station was charging $4.89, a difference of 70 cents.
Across Illinois, the average price dropped 23.3 cents over the past week to $4.46 per gallon.
Other Central Illinois communities also saw declines. Gas prices in Champaign fell 15.7 cents to an average of $4.36 per gallon, while prices in the Quad Cities dropped 16.6 cents to $4.05.
Nationally, gasoline prices fell 15.9 cents over the past week, bringing the average to $3.96 per gallon. That’s 39.3 cents lower than a month ago, but 92.2 cents higher than a year ago.
The national average price of diesel also declined, falling 9.5 cents to $6.19 per gallon.
Patrick De Haan, head of petroleum analysis at GasBuddy, says the recent price declines are largely the result of seasonal changes rather than the outcome of last week’s election.
“Gasoline prices fell in every state over the last week, while diesel declined in nearly every state, and the national average dropped below $4 per gallon for the first time since early August,” De Haan said.
He explained that gasoline prices typically decline in the fall as refineries complete maintenance, increase production and demand decreases with cooler weather.
De Haan also pointed to increased oil movement through the Strait of Hormuz as another factor contributing to lower prices.
He said those conditions could keep the national average below $4 per gallon in the coming weeks.
Despite the recent relief, Peoria drivers are still paying considerably more than in previous years. On November 9, 2025, the average price in Peoria was $3.21 per gallon, compared to $4.59 today.
GasBuddy compiles its national averages using more than 11 million weekly price reports from over 150,000 gas stations nationwide.
