Diesel Particulate Filter Maintenance

**sparc179** · May 28th, 2019 07:54 AM

There doesn't seem to be a thread dedicated to this subject so maybe we should start one now that all new diesel vehicles sold nowadays here in Da Pilipins have this component as part of the exhaust systems.

We all know what it does and how expensive it can be to replace a DPF, but what about proper maintenance to avoid all the hassles and expense if one is clogged up and needing replacement?

The common rule is to drive your diesel vehicle for at least 1 hour at 90 to 100 KpH minimum at least once every 2 weeks to create 'regeneration' conditions that will allow the DPF to burn all of that nasty residue from the un-burned diesel.

Here is my question though, what if you only use your car once or twice a week around the city and nearby areas for short periods of time only, do you still need to do a regeneration run every 2 weeks or will once a month be sufficient?

Your expert opinions are most appreciated.

DPF equipped diesels aren't the ideal choice if one's route is short & slow. They are a known migraine source. Once they're clogged & the DPF light pops, even active regeneration will be helpless. Removal, cleaning or replacement are required...The procedure is tedious & costly. In Europe & Oz, many have resorted to DPF-Delete+ECU tweak til inspection time.
DPF is advertised for the environment. A good guise for its other purpose..... dealership dependence. Be warned. Go petrol.[emoji4]

Thanks for the honest opinion Master Trav, dealership maintenance is something we all dread and try to avoid as much as possible of course. But surely with proper maintenance that dependence can be lessened?

I'll hold out & stay away from ticking time bombs. Thank you, sir![emoji4]
Oh, they require low soot Full Synthetic DPF-Compatible ACEA C3 or higher oils, too.

Just bring the car to an expressway and give it a spirited run every two weeks or so. Take the Skyway and let it run up to what your nerves can manage.

I saw that video and another one from the Ozzie Guru. He does explain how a DPF warning light isn't always the end of the world for the filter.

You mean remove the dpf then disable in ecu? Bad for the health of your kids.

Do you remember the time when gasoline and diesel sold in the philippines was anything cheap? No euro 1, 2, 3, 4, 5? And have you been on a plane about to land at 4 in the afternoon and looked out the window? You could not even clearly see the makati skyline due to the smog. There was this black cloud hovering over the whole metro. Now it's clearer. Not totally gone but a lot better. Nung araw kahit naka-aircon ka ang itim ng kulangot mo sa umaga. Ngayon white na.
