Re: any fuel economy data on the 6.4?
Fuel mileage is a sore subject with me. There are 1.3Ls displacement (79.3 cubic inches) difference between the 6.0 and 7.3. It is widely known that the 6.0 gets worse mileage than the 7.3. No one can really prove why with documented evidence, but it seems that the major contributing factor is what RPMs these engines are run at. Smaller displacement with MORE power should equal better mileage, but the fact remains that it hasn't, so........I'm gonna say that if this engine is built to live in around the same RPM range the 6.0 is, then mileage is gonna be the same or worse, not due to the particulate filter, but due to the higher displacement (bigger cubes is bigger cubes) spinning at higher RPMs than the 7.3. I'm gonna go out on a ledge here and state that if the engineers can make more power than the 6.0 and keep the RPM range more inline with the range of the 7.3, mileage should improve, of course this is just MHO, so take it FWIW.
Later,
