Good point. I cringe when I watch the overhead computer in the Durango when I have it in current or average miles per gallon mode. I get about 17 hwy if I take it easy (70 mph max). But going up long hills, it may drop down to 12 if I want to maintain my speed. Accelerating from a stop, the computer reads 4 mpg, though I've seen it as low as 2 mpg when i stomp the pedal to the floor from a stop.
