if you are reading this from the trip computer dont fool yourself.
I did my own readings from gas mileage app for the Iphone and I mostly vary from 9 to 15mpg.
15 mpg is if I drive like an old lady.
SO TRUE! The vehicle computer is NOT accurate. I have been tracking every one of my 33k miles since i brought the vehicle in Nov of 2009 with an outside program and i am only averaging 10.8 mpg. I do 80% city driving and i will admit when i get on the highway i have seen it get to 16 mpg...but it is what it is.
