Hi yall!
So one of the things bugging me about our Expedition is how thirsty it is at lower altitudes. I only learned about this when we moved to the Tetons in Wyoming - our house sits at 6915' above sea level. Before here, we lived in North Dakota at around 2200', and before that we lived in east Tennessee at 1000'.
In Tennessee and North Dakota we averaged anywhere from 12 to almost 14mpg. Here in the high country we're seeing just shy of 18mpg. The only things I've done to it here were two oil changes, eyeball front end alignment, and recently a dual exhaust from the Y-pipe back. We drove back to North Dakota last year for vacation, and gas mileage dropped while we were there again. Any idea why that's happening?
