| Q. | |
Recent article Cost of Clean by Sean Kilcarr he speaks of the DPF needing cleaning or replacement at 200,000 to 400,000 miles. We at Titan Virginia Ready Mix will not put that many miles on our class 8 truck in eight years; we do how ever put many hours idling our trucks to keep the concrete mixed until unloaded. My question: when do you think the vocational side will have to clean or replace the DPF and is the idling that we do going to load the DPF quicker for more frequent servicing? |

These Diesel Particulate Filters are relatively new technologies, and I am not an expert on this. Your best bet is to get in touch with your truck manufacturer to ask his opinion on cleaning and replacement. I did however talk to one of our dealers who is adept on this kind of thing and he indicated to me that your best bet would be to change or clean the DPF based on hours, which should be indicated in your service manual. We both believe that the idling you do will accelerate the load on the DPF requiring you to service at more frequent intervals. The number he gave me was 42 miles for every hour, so divide 200,000 miles by the 42 and you get 4,762.
