    About the AC: Did you have it set to a specific temp?

    If so, thats why. Cooling you down from 90+ takes more energy (gas) then cooling you down from 80.

    OR did you do max cool and just turn the fan speed to low?

    What do you mean by low temp? 65 degrees?

    Well (unless I misunderstand something here) no wonder: at the lowest temp setting the AC compressor runs continuously. I don't see why you'd want to do that when the outside temp is 50'F.

    no.. I am saying that during that "bad tank" it seemed like something changed on the last part of it and the next fill up. I was getting booming mpg.. .. after the bad tank I am getting like 61 mpg trips.. where as before the "bad tank" I never got that much mpg according to the MFD.
    I was saying that the weather was 80-90's with the ac on before and after the "bad tank"
