Use my uplander for camping trips. I never understood why at sea level I get 20 mpgs and for the same type of driving at elevations above 4000 ft I get 24-26 real mpgs,. That is I fill up and calculate millage.

I think if there is a sensor maybe I can get better millage at sea level.

 

all i can propose is that once your at elevation....its downhill from there...therefore less load going down more load going up.

I can get 2L/100km better coming home than leaving....my town is in a valley.
