Diesel Particulate Filter cleaning solutions

[Durb]

My diesel SUV has just returned from the shop with a new DPF as the new one plugged up at 42,000 miles. This filter is plumbed right off the turbos and requires that a lot of the car is disassembled to remove it. The labor and DPF filter would have been in the thousands of dollars had it not been under warranty. This is a sweet engine but extraordinary fuel economy doesn't compute with a staggering bill every three years. I might re-evaluate keeping the vehicle.

My questions are: Have any of you tried the "on vehicle" cleaning methods such as Liqui-Moly, if so, what were your results? Do any of you use the Lucas fuel additive designed to keep your DPF clean?

Our SUV is a grocery hauler and is not subject to many long trips or hard pulls plus there is no manual regen control. I would be willing to try the solutions if I thought they would work. Sure am glad my truck is pre 2007. Thanks for your feedback.

Back when I first got my very early build 6.7L Cummins there was lots of talk about emissions. Basically the consesus was, drive it hard, keep the Revs up, and always run with the EB on. If your lugging ot around town a lot, you absolutely must take it out and run it hard on the highway for at least 30 minutes every week. Otherwise be prepared to pay for new PDF every year.

That's the problem and the solution.

Take it out and drive it like you stole on a regular basis. Diesels do not like to be lugged around even without the emmissions issues.

Ah, yes, that makes sense now.

In that case OP, I would wager that taking your SUV on a 30 minute "joy ride" once a week would probably be the cheapest option.

Agree - it needs to come up to temp and stay there on a regular basis to allow the normal regen process to work.

I used a 2009 3500 diesel as a daily driver for a while - 3 mile commute. The DPF system did not like that at all. The only cure if not towing was a "joy ride". 30 minutes of HWY driving took care of it.

I have not had any issues with my Diesel Canyon, but my current commute is stupid long.

None of those things are going to fix your dpf or keep it clean. Driving it hard will if everything is operating properly.

What vehicle? Other than a manual clean option/flash I wouldn't trust those other methods. But the manual clean is generally on commercial type vehicles.
