CNN Money reported Monday that the average price for a gallon of regular gasoline in America has increased more than 13 percent over the past 32 days, to $3.73.
As of Tuesday night, gas prices in Naperville ranged from $3.85 at Sam's Club, 808 S. Route 59, to $4.13 at CITGO, 515 E. Ogden Ave., according to GasBuddy.com.
CNN Money is crediting the price increase to a combination of factors, including rising crude oil prices, production cuts and refinery closings.
The Chicago Tribune reported last week that a number of refinery issues in the area have affected gas prices, including an overhaul of BP's Whiting refinery and a fire at a refinery in Ohio.
