DeKALB – According to GasBuddy, average gasoline prices in the state of Illinois have risen 18.3 cents per gallon in the past week. After GasBuddy’s survey of 4,378 gas stations in Illinois, the average gasoline price on Monday was $4.29 per gallon. 

Prices stand 74 cents per gallon higher than a year ago but 12.1 cents per gallon lower than a month ago. The cheapest station in Illinois was priced at $2.99 per gallon yesterday while the most expensive was priced at $5.87 per gallon, making a difference of $2.88 per gallon.

“Just over half of the nation’s 50 states saw gasoline prices rise last week, pulling the national average back up for the time being due to big jumps in the Great Lakes and continued increases in New England and mid-Atlantic states,” said Patrick De Haan, head of petroleum analysis at GasBuddy. 

The national average price of diesel stands at $5.32 per gallon, an increase of 3.4 cents from last week. 

“National diesel supply remains tight, but supplies of diesel did see a slight rise last week. The majority of stations, especially away from the East Coast and Northeast, should have very few issues with diesel supply, though some stations in those regions could see diesel delivery times slip,” De Haan said. 

According to GasBuddy data compiled from more than 11 million weekly price reports, the national average price of gasoline is $3.78 per gallon today, rising 6.2 cents per gallon in the last week. Neighboring areas such as Peoria, which has a current gas price of $4.28 per gallon, and Champaign, $4.05 per gallon, both saw an increase in price from last week’s average.
