Hey guys, quick question? If the regen starts (6.7) and I have to stop, will letting the truck idle let the regen process continue or (seems like I read this) does it have to be going at least 30 mph?

Once you put the truck in park the regin stops, I'm not sure about the 30 mph thing. Mine seem to stay in regin until I stop. At that point when I stopped the regin stopped even before I put the truck in park and I don't think the regin was finished. It won't hurt anything, it will start again probably next time you run the truck.

Maybe this will help:

For me, anything that helps reduce smoke (soot) extends the time between regens. i.e. light on the throttle. No heavy acceleration. Minimum loads. Also helps with mileage.

I'm sick of it, It smells to high heaven because it always comes on in town where have to stop at lights. It kills my wife because of her breathing difficulties. It never seems to come on at the right time. Always at the most inconvenient and I always wind up with several because I'm not going 10 - 15 min somewhere. I wish ford would reprogram the 2011 so we can induce one.

The 6.7's are smarter with regen than the 6.4's.

That would certainly be hard on the emissions system, is there any way you can get a tuner for it? Or do you have emissions testing?
I wouldn't even consider a 7.3 or other emission free diesel for that kind of driving, it will barely warm up !

Fuel Additives
I asked this some time ago and it is worth chewing on, but no one really knew the answer. So we know ultra low sulfer diesel leaves very little ash. Anything else may clog the DPF. Does anyone know a way to find out what our additives do to the DPF at 1200 degrees? I use Stanadyne lubricity formula and there is nothing on their website about compatibility with after treatment exhaust systems. I wonder if it helps or hinders cleaning. I dropped them an email asking this question, If they get back with me i'll post up the response. My truck gets to 1200F pretty quickly once regen starts at 2.66 on the edge. Stops at .98 and continues to lower in passive regen till it cools back down to 460F, but it would be good to know what is left after heating Lubricity formula and performance formula to 1200F. Mike

0.98 is good.
My truck has never been below 1.10 with highway, rural, interstate or towing regens.
I was happy to get it down to 1.14 last night as temps dropped to 550 on EGT4 as I was backing into the garage.

Exhaust System Temperatures
I guess the best strategy for driving with the 6.7 exhaust system is to do as I always do .... drive for economy, limit short duration trips and let it do it's thing.
With the current drought in the southwest and the exhaust system surface temperatures, it sure makes one think twice about driving through tall dry grass!

@ gsxr1300, I have an Edge Insight, At times when it is close and if I head for the hwy sometimes the passive regin will prolong the start of regin I don't always have the time to do that. It doesn't really seem to be a big deal just annoying to me is all. It just seems like it would be handy to have control.
@U235Fishin, One of the local county fire departments has a new Ford brush truck and almost lost it last year working a brush/grass fire. It must of went into active regin about the time they pulled into the grass. Anyway it started it's own little fire and damaged the truck pretty bad the way I here it. Now that we are talking about it I will have to ask my buddy on Tuesday at work what ever happened to the truck and what they going to do about the regin problem on a brush truck.
