I just got back from a trip to Pagosa Springs (from Austin). I noticed that my MPG was considerably better at higher altitudes. From Santa Fe to Pagosa, I was seeing ~11 MPG. I manually calculated on the way back and got 10.6 (Pagosa to Santa Fe). I typically get about ~9 around Texas. This is an NA Gas Engine (5.7l Hemi). My only explanation would be gas without ethanol or less wind resistance. Any thoughts?
