hi folks,

from your experience is there any noticeable difference between 7.3 and 6.0 fuel economy?

According to Ford, better MPG was not a design critieria for the 6.0.

That being said, Ford then went on to state that in its tests, the 6.0 got 10%-15% better MPG's than the 7.3.

So you are looking at 1, maybe 2 MPG's better with a 6.0 best case.

I have had my new (03) 6.0 for 40 days,traded my (00) 7.3,
New 6.0 is at lest 10% better on fuel may even be better than that.

The transmission is what makes the truck such a joy to drive.Same power band all the way up to highway speeds.

I am a real happy 6.0
