Regeneration Frequency

[Big Angry Hillbilly]

We have only sold two or three 6.7 trucks at my dealer, and haven't seen any of them back for service yet.

What are you guys seeing for regeneration frequency on the new trucks? How much does it beat the fuel mileage up when it's in regeneration?

Inquiring minds want to know!

One of my local dealers here let me take one for a couple days earlier this week and I saw the regen message pop up right around 500 or so miles, and saw it for no longer than 10 seconds. Not sure if that was the entire process or not, but it wasnt showing the message for long at all and from what the screen was telling me, it didnt kill the mileage too much.

I would imagine (since the 6.4 is now this way) the regeneration message only comes on briefly, and then goes out. If you do a 'system check' through the cluster, you will likely see "Cleaning Exhaust Filter" as one of the last couple messages as you cycle through it.

That was the FIRST regeneration on the truck at 500mi? I wonder how frequently it will regenerate after the initial regeneration. I know my 6.4 truck didn't regenerate for about 600mi the first time, and I typically was doing at least one regeneration per tank. Sometimes twice.

My first regen was has approx 150 miles and it took my MPG down 1 -2 based on what the computer was telling me. My second regen was around 250 but I had been idling alot between the first and second so I am discounting the distance between regens as due to the long idle time, especially since I now have about 450 miles on it and I have not seen it do a third regen.

I get 2 regens per tank since lifting it. I only get 300 miles per tank (hand calculated and adjusted for my 37's) and that is mixed city and highway.

before lifting it, i would only get one regen and 425 miles per tank.
not sure why the regens kicked in but they kill my mpg's. i can't wait till tuner and a delete.

I'm wondering if regen frequency would stay the same as the truck gets more miles on it?

So far I have less than 400 miles on the truck and have seen the "Cleaning Exhaust Filter" message 3 times. It doesn't feel like it lasts very long and not too sure if this is due to short distance driving while in the Keys, but I plan on getting the truck on the interstate this weekend to see how the truck does.

probably every 125-150 miles I am getting a regen, that is just a ballpark, I can watch it drop mileage about 1.5-2mpg

Has anyone had experience with regen pulling REALLY heavy and hard???? Everyone said with my 6.4 should regen less pulling hard because the EGT's were already hotter, but I found the exact opposite, pulling big and heavy my 6.4 regened every 45 min. and they lasted as long as an hour, usually bringing my milage down in the 3-4mpg range. I am just wondering how regen is going to work on the 6.7 when pulling heavy, I thought I understood that the urea injection ment less regens??????? When I say pulling hard I mean grossing over 30,000lbs or something close to that on long trips.

Well, took my new 2011 out last night and just finished a 350 mile round trip and the truck regen'd 3 times, each regen took place at 100 to 120 mile intervals, regardless of going 55mph or 70mph, and each regen lasted for approximately 10 miles, based on watching the "Instant MPG" gauge. This is consistant with my previous post of the truck regen'ing 3 times inside of 400 miles. Is it possible the 6.7's are programmed to regen at this mileage as a form of "self-maintenance" ?
My only concern with the truck regen'ing this frequently, is "oil dilution".
Does anyone think this would warrant any concern?
