I can get 40+ MPG doing 80 mph if the road allows me to stay in the 2000 rpm range. There are probably more components to fool. The engine will easy rev 6000 rpm. Driving at 3000 rpm and making more oil changes would be worth the effort.

If you have read the 100+ hypermiling tips(link at top right of this website) you would realize that maintaining a constant speed is NOT the most efficient option. When you allow your speed to vary, you open up a whole new world of gas mileage.

By drafting? You do know cars are a little more complex than just using a resistor right? It isn't like the car just DECIDES how much fuel will be burned depending on what rpm you are at.
