NRALIFR,

Having owned both a 6.4 and now a 6.7, I can say with certainty that neither gave any constant indication of a regen taking place.

That was part of the reason I chose to install an Edge Insight CTS monitor. There is a small red "R" that appears at the top of the screen when a regen is taking place. The "R" appears about 10-15 seconds before the DIC shows "Cleaning Exhaust System" and it disappears as soon as the regen is over (or the truck is shifted into Neutral or Park).

As far as miles between regens, I can also say that my 6.7 performs regens about 40-50% less often than the 6.4. I had the same CTS installed in the 6.4 as I do now in the 6.7. I use both trucks as a daily driver and to tow the same trailer, so the comparison is valid in my view. The regen cycles are about the same length in time.

I get better fuel mileage out of my 6.7, even though I now own a dually (compared to the 2010 250 shortbed of my 6.4). Injecting raw fuel into the exhaust stream 40-50% less often must have something to do with this...

NRALIFR,
Sorry for the late response but it appears 45 ACP answered your question? Honestly I can't say what the life cycle of a DPF is on a 6.4 since most have deleted them. Having said that these emission systems really need to be highway driven to live a long healthy life. I know a guy at work that has a all stock 09 6.4 PSD and his daily commute is ~ 45 highway miles and he's approaching 160k miles with no issues on the DPF.

Thank you both for the response. As I mentioned earlier, I'm just trying to get a feel for what "normal" is for the 6.4's. I don't know anyone locally with one to compare notes with.

I've owned the truck in my sig since Feb/2012, and it had close to 60K miles on it then. It's previous owner was a building contractor, but I don't really know how hard it was used. I would think most of the miles would have to be highway miles to run them up so quickly. It has about 78K on it now. I don't drive it much unloaded, so I don't really know what it's unloaded mileage is. Most of the time my camper is on it which weighs about 5500lbs, and the mileage typically ranges from 9.0-10.0.

45 ACP, it sounds like you were averaging 225-325 miles between regens on the 6.4. I"m not sure mine has ever gone 300+ miles between regens while I've owned it. I think it was going at least 225, though. For the past year or so, it has been varying from 100-180 miles between regens, though. The regens last about 15 miles, and the mileage has stayed pretty consistent even though it seems to be regening a little more often.

FishOnOne, if you think about it, ask your buddy if he knows how often his 6.4 regens, and how long they last. It would be interesting to know that on a 160K mile truck.

Thanks again.

:):)

I'll get back with you on the regen frequency. In addition to his truck being his daily driver he also tows a large gooseneck trailer to their South Texas ranch either hauling tractor/shredder, round hay bails, or a couple Polaris vehicles on a regular basis so it get's worked pretty hard.

Keep on truckin! :B
