@BruceT, I asked a similar question of our 4WD group since they were adding engine analysers to thier cars, one of the screens shows current fuel consumption. It worked out that it was around 2l/hr more @ idle with the AC on.
I'm sure there is a margin on the DTE calculations, but that is running it close!
