Keep reading these forums and you will find many useful ways of increasing from that 43mpg. Have you looked at some of the pulse and glide threads? Thats where you get up to a top speed (the speed limit or what ever you want to set yourself) Then you take your foot off the gas and then reapply it until you don't see any charging coming from the car. You will slowly slow down. Pick a low speed you want to hit and just continue until you hit that speed. Then Accellerate up to your top speed again and repeat.

Another thing to do is to keep an eye on the instantanious FE gauge and see what it takes to keep that thing as high as possible.
