Ok kids, I recently went on an elk hunt in Colorado and drove through the mountains to the western side of the state. I filled up prior to entering the mountains going to and coming back and noticed something very interesting. I got an extra 30 miles per tank going through the mountains as opposed to cruising along the flatlands of Kansas & eastern Colorado.

Now the question is why. If anything, I expected to get lower mileage going through the mountains just do to the extra effort going up. After having thought about it, I came up with 3 possible scenarios as to why I got 30 extra miles per tank. Let me know which one you think is the right one:

#1 - Elevation - Higher elevation mean better gas mileage. (But since there is less oxygen at higher elevations, this doesn't make sense to me).

#2 - Gravity - While I was going up I was burning more gas, but coming down I saved a bunch more (personnally I think it should be a wash)

#3 - Gas Fairy - A hot little fairy was putting gas in my tank when I wasn't looking. (I picture her as looking like a cross between Tinkerbell and Bette Paige)

So whatcha think it is? Other opinions will also be entertained.

although the fairy idea would be awsome if true.

I would side on the using less fuel going down the mountain idea but with the added idea that you can't really keep your foot in it when handling mountain curves?

Just a thought! what ever the reason now you can justify going to the mountains more often!!!!!
