Which AC panel unit does your vehicle use, the analog or digital?

My experience is the same as @
Tcoat. Below is my average MPG by month since May 2012 through today. My AC runs pretty much full on late May through mid Sept in Atlanta. July and October are months I'm most likely to take long road trips in the 86, which accounts for the increased MPG there.
