Just filled up the park avenue yesterday, got a whopping 14 mpg. That is mostly intown, about half with a/c running, minimal idling. Tank before was 18 mpg, with some highway driving. Looks like this car is in need of attention...

Also, it seems like the a/c pulls a lot of power, almost more than it should, or is this normal?

AC hp drain on an L27 should be barely noticable.
