I suppose if they conducted an acurate towing fuel economy test where they started with a clean dpf and ended with a clean dpf it might be interesting.
Winner winner chicken dinner... Yet every diesel fuel economy comparison fails to even touch on regen frequency and duration which have a bigger impact on economy than anything else.
I can guarantee you that the DPF's were getting hot enough to passively regen up that hill. Anytime you are at high load for periods like that will trigger a passive regen due to the DPF getting hot enough without the use of extra fuel.
It is mainly when you are not towing or with a light load that the DPF needs to inject extra fuel to actively regen in order to get hot enough to oxidize the PM in the DPF.
