cleaning exhaust filter

[bmh993]

My '08 350 with 20K mi started doing the "cleaning exhaust filter" at 17K. It happens every 150 mi +/- 20 mi even during a 9 hr. interstate light (5K #) tow at 70 mph and kills the already lousy fuel mileage.

The dealet diesel "expert" says this is to be expected and it's a lousy engine design by International.

Is there anyway around this situation and/or is it normal or abnormal???

Thanks,
Frustrated and annoyed

It is normal in the design of the DPF equipped trucks. Best bet, DPF delete and the required tune

my 09 f250 has 800 miles on it and it has cleaned the exhaust filter i know atleast 5 times in a week since i have had it i have a had about 3 tanks of fuel through so i would say no it not abnormal

that really depends on driving habits. if the truck isnt finishing its regen(slowing below 30, stopping, things like this interrupt it) than the truck is going to seem to regen a lot more. And 800 miles, 3 tanks, lots of city driving, plenty normal.

yeah thats what i figured when it goes in to regen mode i raw dog the crap out of it

you don't need to do that, just keep the speed up, and let it finish its job. thankfully mine seems to regen when the wife going to my parents, and its an hour one way

My Truck so far has Regen'd about every 400 miles, lasts 20 mins, Avg MPG dropped from 14.7 to 14.6.

[jeff_willis96]

The 14.7 to 14.6 was just the last time it Regen'd. Previous times it regen'd I really got on it and the MPG Dropped by quite a bit This time I never really got on it. I also always have let it finish the Regen before I shut it down, which is kinda of a pain but not too bad because its a new truck and I have another car that is my commuter so I dont drive it that much.

Dpf delete and a tune Is the way to go. Increase mpg and no more regens
