This is by no means a scientific experiment, but I have come across a partial solution for those who drive their trucks through a city, and encounter a regen while going light to light until they get back out on the road. A neighbor of mine who has a 6.4 told me about it, and it works for both him and I.

Background: The 6.4's tend to "make oil" when certain conditions are met, and it usually happens when there is a stuck injector, or while regenerating at idle, or in city traffic.

Partial solution: IF you're only going to be stuck in the lights or cone zone for 15-30 minutes, when you get up to the first of the long string of light, put it in PARK when you get stopped, and then put it back in drive. There appears to be a counter in the PCM/ECM/Whatever that kills the regen for 15 minutes. After that, if it starts again, you can do it one more time (for another 15 minute break) before getting the "DRIVE TO CLEAN..." one.

It doesn't stop the truck from doing a regeneration, but it can buy you some time until you get back out on the road. I've done it with both one or two times in Park and it works. I haven't made any amount of oil that registers on the dipstick in 8600+ miles so far, and one oil change. Granted it's new, but I hate seeing "CLEANING EXHAUST FILTER" while stuck in traffic. Sometimes it appears the regen is complete enough to make the computer happy, but it stays in regen for some reason. (maybe to make the DPF extra clean?) I know this because after the Park and 15 minute time out it doesn;t go back into regen.

Just trying to figure the thing out so I don;t grow oil, and hopefully nobody else does either.

 

neat info.. will try this myself.. I was at 2.5% fuel dilution on my first sample, and don't see this event (regen and traffic) often, but..

You might also consider using tow/haul in town so as to increase your RPMS.

 

I do that when my speeds are low (like 20-30) and with a steady throttle. If I can keep the RPMS around 1250-1750 (55-65mph) I won't use the tow/haul. Ever since I doubled up on the Diesel Kleen, my regens are few and far between. I've only been stuck in the light to light a few times with a regen, and the PARK tip definitely works well.

 

If you put it in park does it kill the regen if it is in progress? Or does it just delay the start by 15 minutes? I'll keep this one in mind....

 

Putting it in Neutral is also suppose to kill it, IIRC it was part of one of the updates after the '08s came out.

 

I tried this just a hour or so ago. Went into regen so I put it in neutral at about 30, still regenning, until I got to about 5 mph, I was coming to a stop sign. Then it stopped, put it back in drive, drove another 16 miles and never went into regen. So the 15 minute rule and the neutral rule did not apply on mine. Now I do not have the latest flash, that could be the difference.

 

I think your regen was done, or DPF was clean enough to not warrant starting again after the 15 minute period. I've noticed that, also.

 

Neutral will if the truck is stopped.

 

It kills it if it's in regen....it will restart if it needs to, 15 minutes later. I WISH there was some counter that would pop up and say "REGEN STARTS IN XXX MINUTES". that would be FANTASTIC!!

 

I wish the message regen would stay on the display until it completes. That way we know if it complets and how long (time/miles) it took. I try to set Trip B every time I see a regen message so I can calculate intervals.

 

they just took the message OFF the display cause it was causing too many problems for the general customer..

I must have an older flash on mine, and it stays on, and then it just disappears. No "REGEN COMPLETE" or whatever the original old one said. However, it works just fine for me, so I have a sticker on my OBD-II port that says "DO NOT FLASH".

 

Yeah, customers were complaining that they didn't know what to do, keep driving or just turn off the vehicle when the message was displayed.

 

SEIC supposedly prevents the DPF from regenerating (I read this somewhere, probably forum postings so who knows) so it’s said to be sure and turn off the switch when not in park unlike previous non-dpf models where operators would use the park brake to enable/disable high idle and leave the switch on.

Maybe BCP follows these same rules about not regenerating when voltage is applied (since BCP doesn’t power any PTO operations).
Would this in theory prevent regen if you’re attempting to stop it by putting it into park anyways? Then when you get out of the city traffic and back on the open road soon after, make sure you turn off the switch so it can regen properly (probably after the same 15 minute delay).


My disclaimer is that I’ve come up with this in my head.
It doesn’t mean this would work or is recommended.
The other question would be if the PCM logs information about voltage applied to enable either BCP or SEIC while driving and if that would cause a warranty concern related to the DPF.

About the only other option is to drive the truck, let the computer worry about the DPF and keep up with fluid checks and maintenance as normal.
