Sooting DPF Filter

[KBcoltcompany]

Yeah, it was. It lets people know that when guys get on here about their problems, we don't need to hear who ISN'T having problems, but rather, who may be having the same problem and what can be done about it. Kind of a dick move when the reply is "mine's just fine". I mean, who cares?!

Same could be said about a guy that doesn't even own a 6.7, or a Cummins for that matter, jumping into a thread

mines been good so far,08 6.7. had one code p2000, cleared with edge never came back on, always drive with exhaust brake on helps with keep dpf clear, take for a good hiway run every tankful, sound like a waste to keep truck running right but its the wave of the future, or hit a hard bump and have all the emissions crap fall off ha ha

I just love it when the Service Writer tells me I have to drive it at 2200 RPM. which can only be done on the automatic if I drop into manual shift. As the automatic will drive all day at 60 MPH @ 1400 RPM. According to Cummins the engine was designed to run at 1400 RPM for maximum fuel efficiency. I have over 100,000 miles on a stock 6.7, however I can tell you the EGR, CAT and DPF are about to have an accident and fall off the truck so the engine can breath pure air and get rid of all the once burned soot out the tail pipe. I run anywhere up to 12-14 hours per day at highway speeds and the only time I have ANY trouble is when I have to run around town, this truck just is not set up to run around with city folk. lol

well i had one problem with the dpf getting clogged they had to change it all my solution: banks speed and eliminate the dpf and the egr its gonna run like a bigger 5.9 the 6.7 is not the problem the dpf system is not to mention who wants a dpf that slows you down kills your mileage and makes life a hassle i say f&*k it take it off!!
