Re: any fuel economy data on the 6.4?
Why does everyone seem to think that DPF regeneration is going to exact this huge fuel mileage penalty on these engines? I get the impression that regeneration happens rarely (on the order of days or weeks) and briefly, so there really shouldn't be very much fuel involved compared to what the vehicle is burning in its normal course of running.
The 6.4L may well get worse mileage, just like the 6.0 does compared to the 7.3L (despite Ford's early promises), but it doesn't seem like DPF regeneration should be the major reason why.
