I have been pulling about 52 mpg on the highway. That is in the morning with no a/c running and 68mph. That drops to 49 or so in the afternoon, when I have the a/c on.
I get between 37 and 42 in town.....unless my wife wants to be lazy and wait in the car with the a/c running.
It is amazing how much fuel gets wasted when you idle for long periods!
