      I hear hissing on the highway quite often.
      I am getting poor mileage as well.
      I got 27 MPG on a tank of FULL highway straight to LA with plenty of drafting etc.. I know it should be better than that.

        Your mileage is normal. Most of the people claiming 30-35mpg are either full of it or don't know how to calculate their mileage. It takes a lot of effort to get these cars to 30mpg. Definitely not stock.
        Did you intentionally cite the lowest figures possible?
