Cheapest Gas In Oak Lawn: $3.96

Fun fact: On today's date in 1989, Warner Bros. released Batman and created a cultural phenomenon known as "Batmania."  And, according to IMDB, the famed Batmobile that helped boost Batman's "cool factor" is powered by a Chevrolet 350-cubic-inch engine with performace extras to boost horsepower by another 200 watts, resulting in a dreadful seven miles per gallon.  Ouch.  But if you're not Bruce Wayne and you want gas at the cheapest price, head on over to these two stations, where regular unleaded costs $3.96 per gallon.
