Agreed. Short trips, cold ambient temps, cold engine temps, heavy right foot, fuel quality, etc. all lead to incomplete/frequent regens. Mine starts a regen within 1 mile of either arriving at home from work or vice versa. I have to take it for spin once in a while to warm it up and complete a filter clean.

 

The mileage I posted was each time its regened. Its done it 3 times in 810 miles

 

Hey Ron, That must be some sort built in glitch with these trucks, same thing happens to me. LOL I did manage to get a couple of regens in while out on the road during a recent vacation, it's nice to see it clean all the way. I didn't keep perfect records on the regen cycle but close to 500 miles between them, I didn't see the second one start but I noticed on Edge that it had happened.

-Edit- I should have added that with thous regen numbers I had my camper on and driving in hilly country averaging around 4000' elevation. I fill kinda bad about this, but I must not watch my gauges enough, I have only seen the truck go into regen a couple of times on the dash. If it wouldn't be for my Edge, I wouldn't even know it most of the time.

 

It's 11 miles from my house to work. The engine temps are just getting up high enough to initiate a regen just before I get there. Park the truck for 12-14 hours, then repeat on the way home. After about 3-4 failed attempts to regen, I take a longer route to/from work and complete a cleaning. I need to fix my work car so I don't have deal with it on a daily basis. Or cross over to the dark side.
Me and ma are paying down debt pretty fast right now getting ready to retire in the next 3-5 years, so there are some available funds for a little, enhancing, shall we say. I'm toying with getting a newer model truck in a year or two and just haven't committed either way yet.

 

Why? Don't think about it. Just drive your truck like you normally would. Only time you'll ever have to think about it is if it is it tells you there's a problem. Otherwise, put it out of your mind.

 

Ah that makes more sense! I was trapped in a paradigm on that one. You most likely missed the first one, but otherwise those numbers are about average if you only drive short distances. A lot of stop and go is the worst. I don't necessarily need to be on the highway if I can just travel some roads where I can go at least 8-10 miles without having to stop and takeoff again. After everything is up to full operating temp, a steady run of more than 5 miles will start to passively burn off some soot. My daily commute of 8 miles each way doesn't normally allow any passive regen because I have to stop 5 to 6 times in that distance and the speed limit is 40 or less.

I just got back from a weekend trip with the almost 16,000 lb toyhauler and starting out at 2.51 soot count which was getting close to an active regen, in less than 100 miles the count was down below 1.00. In fact, the count was at 1.10 when the truck decided that it needed to do the deed anyway even though the soot level was lower than any active regen has ever taken it. After about 320 miles round trip, my soot level was at 1.09 this morning when I left for work. Towing that trailer at 60-65 mph, my EGT1 reads 800-950 degrees which is more than plenty to burn off the DPF. When towing my 6'x12' utility trailer with a golf cart on board (about 2,200 lbs gross), there is enough load for a little more passive regen than an empty truck, but still not enough to extend the regen distance very much. I'm guessing it takes 7-10,000 lbs to get fully functional passive regen. Basically these engines were made to work hard and you are going to have to live with some compromises like frequent regen if you aren't using the truck to at least 50% of its potential.
