[QUOTE="CATDiezel, post: 1067722, member: 4387"] Yes. That's generally the case. But a dirtier burn may not necessarily mean large soot particulates. I'm speaking gaseous dirt. Here's the trade off. Use more urea or use more diesel. There's a certain point where urea won't react due to cool exhaust also. The fight between keeping cylinder temps up for the sake of the SCR housing where the urea acts is borderline magic on a variable speed/load engine. Unfortunately in order for Ford to not get there peepee stepped on by the EPA the safe trade was fuel consumption in allow the dpf to work alittle more all while trying to give the consumer a better turbo that flowed better. They designed this one around towing and efficiency there. Again a sacrifice for "cruising" So many variables here its almost impossible to explain. Lol [/QUOTE]
