DIY DPF cleaning?

[LenTex]

Any suggestions on a good chemical DPF cleaner that I can somewhat easily do myself? I’m not ready to give it an exhaust diet yet and I’m not comfortable with cutting it out, pressure washing it and re-welding it myself.

I’m getting 12 mpg with a lot of highway, high speed driving, and very frequent regens. The truck’s previous owner had 1/3 of the hours in idle, so I’m thinking the thing is pretty clogged. 2020 standard 6.7 with about 65k on the clock.

Thoughts? If I need to give you more pertinent information let me know.

Be nice if there was a way. Mine gets idled a lot because of the Arizona heat....

the only way I've seen it done is at a local shop that specializes in dpf cleaning. it's a fairly interesting contraption they hook the dpf up to.

What are you calling "frequent? regens?

Enough to throw a code about every week and a half to two weeks saying it has run regens too frequently

Im a diesel machanic for Peterbilt, i deal with alot of aftertreatment issues. DO NOT put any liquid through your dpf or scr. the cleaning process consists of 1200 degrees for 8 to 12 hrs in a large ceramics oven, then 120 psi air pulse machine to clear the ash from the doc/dpf only! scr cannot be cleaned. we have had customers attempt to "wash" docs and dpfs, but as soon as the liquid/water starts to steam when heated the core cracks/shatters/melts.

We use a radiator shop. Its reasonable. Get new gaskets, they aren't reusable.

Thanks for the heads up. Any suggestions of where to get it done right?

What do you typically charge, or maybe a range of what you typically charge? Just trying to set my budget.

Sounds like it's still in warranty and with it throwing a code I'd let the dealer deal with it.

Powertrain warranty applies to emissions?

Not sure about diesels but emissions are usually covered to 100k by Fed law.

That’s far less than I was thinking. Thank you.
