Romp on her to “Clean it out”

Hey all. My first post here . Recently purchased a 2019 Chevy 2500 crew cab Dmax of course . Currently at 510 miles. I just would like to see your guys inputs on the topic I wrote in the title, for the new diesels with the DPF systems.

I’ve always heard people say you have to get on the throttle here and there to “Clean it out” I wondered if this has any relevance to the new diesels, since burning extra fuel and beating on something is not my forte.

Im 27 years old but I drive like a 87 year old grandmother. I haul my landscaping trailer with mowers a bunch of short trips in town 3-4 times a week on the side of my reg 7-4 job that’s 4 miles from my house . So obv I’m concerned about the dpf system and what’s best to keep it hot and flowing . Thanks !

Just a random flooring here and there won’t help, might actually make the soot build up worse, it needs sustained heat to do any good. I drive my 16 a lot like what you just described and knock on wood no dpf problems yet. I do take it to the next town over (30 minutes each way, 60ish mph) whenever I need something from there but I don’t make special trips just for the sake of driving the truck.

Worse huh. I wouldn’t have guessed that. I’m not a fan of beating on anything I own . This is my first diesel , had a 3500 gasser that was a 2012 with 42k miles lol. Easy miles too

stomping wont clean anything out, if your worried about injectors run a lube/ cleaner through the system and for the dpf/ exhaust if you enter into a regin and turn the truck off it will resume where it was before you turned it off once it reaches operating temperature and if that isn't enough to clear it out then you will get a message on the dash telling you a regin is needed

No, don’t romp on it. The soot production is highest on a rich mixture, which is what you have while accelerating. Ever seen one roll coal. More fuel is introduced than can be used, so it just vaporizes into soot.

A heavy load at sustained speed is the best for keeping dpf clean.

Around town and 15 to 20 minute legs to feed store I only get about 168 miles between regens. But about 450 between regens hauling trailer. But my trailer trips are only about 90 miles each way.

The very best thing for your fuel system to add lubricity and clean the entire system is Bio-Diesel. even a B5 blend is better than any additive you can buy.

It does nothing for the regens however.
