Diesel Particulate Filter Maintenance

[sparc179]

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.

Hehe, not many of us have the luxury of choice sir.

Thanks again for the additional suggestment. Drive safe!

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.

Hindi ba puwedeng idisable nalang sa ECU yang dpf

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.

Long story short, as long as you can do a sustained run of 100-120KpH for about 1 hour each way at least every 2 to 3 weeks, you should be good, correct?

grabe ang dami boladas pag desel talaga.

Tapos paparahin lang kayo ni ASBU MMDA.

Bayad pa tollgate.

Kaya may dahilan bakit pinas at india lang madesel.

I regen my dpf at naiax, running 60kph. As long as regen starts, even when you stop, it will still do the cleaning until it finishes.

You may see it via torque pro, catalyst temp reaches 400c.

You don't need 120kph to do dpf regen. 60kph tops if enough.

Manufacturers are not stupid as to activate regen at 120kph above. Its above the speed limit of most countries.
Example, usa, Australia, uk, 110kph limit in highways.

To revive this thread, there is a schematic diagram of the Euro 4,5 & 6 exhaust pathway of diesel engines in the Voltronic Oil website catalogue (if you care to browse through it). The main difference in Euro 4 vs Euro 5,6 diesels is, the latter 2 have to have their exhaust fumes treated via SCR catalyst (ad blue chemical) while the Euro 4 do not. Both have DPFs. So, E4 diesel engines in the Philippines, to meet E4 emission requirements, will definitely have a dpf. SAs don’t know what a dpf is & don’t use the recommended oil. Actually, it is easy to check if your car is equipped with one. It’s a big metal canister thats connected to the exhaust manifold & it has a sensor & piping (for diesel fluid). The use of low SAPS oil ACEA C2 & C3 or E9 is also recommended since it contains lower residues. Since my crossover reached 25k, I was luckily able to find a dpf cleaner & engine decarbonizer from Voltronic that isn’t too pricey. Luckily, John Cadogan, in his experience with diesels in Australia, hav’nt heard of any dpf issues in Kias & Hyundais, so that is a relief.

nabasa ko yung link. Magkakaroon ng mediation. Sakit talaga sa ulo ng desel ang dami keme-keme.

ayan may nagcomment pa. I agree, na bawiin yung binayad and buy a gasoline car.

That's why i would never buy Hilux, they dont care. Take your money and refused to fix or help sort the problem. I know 3 people with this issue and toyota didnt care.

Kasi ang Toyota will sell irregardless of problems kaya lang syempre, may responsibilidad sa buyers dapat ang dealer. Diesels will always have a market. Kailangan lang talaga piliin ng buyer paano nya gagamitin yung diesel car. Kung panay city driving, mabilis talaga mag clog yung filter. Di lang dito yan, even in the UK & Europe.
