2016 DD13 GHG17 Cascadia - DPF filter longevity

[dd13cascadia]

Hey guys! Been lurking here for the longest time, barely posted. Figured i would change that, so i would make a thread to share with others that might be curious about this matter in particular. I hear, read and see lot's of differnt info across the board when it comes to the longevity of the DPF filters and the onebox. Well.... i have invoices and maintenance records to back my statement's up, since the truck was purchased up to now.....

2016 cascadia, with the specs mentioned on the topic title and just got the DPF filters changed as a precautionary measure at 836k miles. They were still OEM. Got cleaned at the dealer at around 630k miles in October 2022, the first time around. The mechanic said that they had a few soot spots, but nothing crazy and they would last more if i wanted.

I never idle overnight. Shut if off after 5 minutes whenever possible. Always warm up in the morning until the oil reaches 60 degress celsius then i drive. I use full synthetic 10w30 valvoline premium blue. Doesn't burn oil... oh! and since 2022... i never got the DPF filters cleaned. According to my OTR performance tool, the pressure differential on the DPF and temps were all normal while driving, but i started having interment MIL light flare ups. So i got the wiring harness for the aftertreatment changed as well. First time it got changed was in 2019.

Saying my prayers and got my fingers crossed, to see how much the onebox will last but i am hopefull that she will never quit on me! :D

Whats your take on this?
