Above 62 air resistance starts cutting into your fuel economy too much which is why the national speed limit was 55 mph to start with. If we want to stop importing so much oil they are going to need to cut the speed limit down again.
Part of my conspiracy theory was we peaked in suv ownage around the same time that they opened up the speed limit. Doesn't take a rocket scientist to know we are going to increase our national oil consumption by over 10%(I'm a pessimist and am thinking high teens and low 20s) just by adding 10mph to the speed limit. We really shot ourselves in the foot.

1. Speed
2. Weight
3. Frontal area
4. C/Drag (shape)
5. Driving style.
BTW: Jacking the truck up 5 inches it retarded, it makes the frontal area increase tremendously, and screws up handling a lot.
