9.6 MPG, that deserves a picture? What about your tires, still good?

Sport mode on at all time here too... I press the Start/Stop button then while my hand is around there I press the sport mode button...

As of my MPG right now I average 14-16 MPG overall (I got up to 28 with highway driving and as low as 8... some other time...)

Thumbs down Rear Tires Are Getting Close To End Of Life

Yeah I am going to have to change my tires here pretty soon. The highest Octane grade of gas we have here is 91. My friend has a company that sells Alcohol Water Injection systems http://www.alcohol-injection.com/. He said that if I installed one of the kits it would help me get better gas mileage. I will post a picture next time I get a low MPG number.

When I fill up my tank I get an estimate of 172 miles per tank which brings it down somewhere around 11.25 miles MPG. When I first bought my car it would read around 200 MPG. Does anyone know if it changes after awhile depending on your fuel consumption? I don't even get 172 MPG. When I use the odometer I get around 158 MPG on better tanks. I can only imagine what I will get if TRD ever develops a Supercharger .
