And yeah really I haven't improved percent-wise all that much, because the car was already pretty efficient to begin with. There are far fewer large, easy improvements. And, my car already draws a fraction of the fuel yours does. You probably save more $$$ gaining 2mpg than I save gaining 30mpg. Anything you can do will help a ton.
