Gas prices across Central Illinois have been on the decrease for several weeks now.
AAA in Chicago says that oil refineries are switching to their winter blend of gas which is cheaper to produce.
Prices in Peoria average around $3.50 which is $0.30 cheaper than last month. Prices in Bloomington average near $3.18 which is also about $0.30 cheaper than last month. AAA says that prices should continue to decrease in coming weeks unless a natural disaster hits.
