Answer is 5th gear since the rpm is higher. It has nothing to do with the speed.

Well, Armand, I guess you're right. Yes, if one is stupid enough to purposely drive around at 70mph in 5th gear, he'll get worse mileage than if he drove in 6th gear.
Someone call CNN and inform them of Armand's scientific breakthrough!!!
Hey, I just thought of another one: Driving w/o the parking brake engaged improves highway mileage (speed being constant, of course).
Energy crisis - SOLVED!
