Thanks, I think its pretty great mileage too considering the temperature.

As for the PTC heater, this is how it operates. It seems to me that the programming / logic is highly programmed to provide comfort, not necessarily efficiency.

Quote:
It is called PTC heater (Positive Temperature Coefficient) and it will operate under the following conditions:

-Engine running
-Blower fan on
-Temperature setting: any except MAX cool
-Outside temp 59 degree F or lower (ambient temp sensor is at top of lower grill opening on driver side)
-Engine coolant temp 167 degree F or lower
-Generator output 70% or less
