Honestly Harry, our gas taxes have been a joke for a looooong time compared to every other country in the world. I think the federal tax is $.19/gal, as is the Illinois State Gas/Gasahol Tax. Not sure about in DuPage or Kane County, but if you fill up on Cook County, that bumps it a bit more. State tax alone, we're actually cheaper than Iowa ($.21) or Wisconsin ($.32.9?!)! http://www.illinoisgasprices.com/tax_info.aspx
