Yes it is a fast mpg test and not a long run test but it does show that the 7.3 is still a gas hog, even if it was a better day and driving longer still appears it wont break the 7 mpg range.
I have 16-25 MPG towing my trailer. Does it means my engine more efficient? No. It means my trailer is small.
With gas engines we are talking about 0.1..5% difference in efficiency, not 20..100% difference in loads. To find which engine is better should be pure "scientific" comparison, otherwise it is wind, speed and other 10+ factors.
