That is a nice theory, but in real world practice (on my truck) I can tell you that 4WD eats a very noticeable amount more of gas.

Off the top of my head, I lose about 3 mpg in 4WD.

When your are only getting 18 mpg hwy, and 13 mpg city this can add up quickly.

Lets say I average 15 mpg half/half, 12 mpg is way too low for me.
