Which would use less fuel?

I agree Mike, and I doubt it's very accurate. But, my above claims were made with it at sustained speeds/throttle. So, whereas the exact numbers might not be right, the position is enoguh to make some conclusion.

The only variable I change is the load. I keep the throttle position and speed the same. In such an experiemnt, when going up hill at 70mph in 5th vs 4th, most often 4th reviels the higher MPG.

YMMV (ha ha ha)
