Illinois gas prices have dropped 15 cents per gallon over the past two weeks, with the state average now at $3.42. AAA attributes the decline to easing summer demand and lower crude oil prices. Chicago prices remain higher than the state average at $3.78. Prices are expected to remain stable through Labor Day.
