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]

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.

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.

Hehehe, my choice would be the NLEX from San Fernando all the way to Urdaneta and lunch at Dagupenas. I still love the boneless bangus steaks there and the binagoongang crispy pata which is to die for, literally

So it's every 2 weeks still. I guess that gives me an excuse to go out of town more often, hehehe.

Thanks for the advice Master E.

If you want to test how fast your ride can go, I suggest you take SCTEX to Subic route. The Clark-South to Floridablanca section is pretty much a no restriction zone. TPLEX is another option. Just watch out for a parked Innova or Ranger or Hilux but you will be able to see them far enough for you to slow down.

We do an SCTEX run once every 2 months Master E, wifey has a place she likes to go to just outside SBMA, a nice little resort with a beautiful garden.

The thing with SCTEX though are the uphills and downhills, really allows you to test your speed and torque. Plus it's a scenic road most of the way. We always enjoy it.

Are all diesel vehicles being sold locally really equipped with DPF already? As in 100% of all diesel vehicles?

I believe so, yes. As part of the mandate to decrease toxic emissions from most vehicles.

There are countries which don't follow such strict standards, of course, but here in Da Pilipins, it is required now.

Actually, only the Euro5 compliant ones are DPF-equipped. Dealerships stay mum.

Ah ok, I guess I was misinformed or disinformed on purpose. What SAs will say just to get a sale, it seems.

Good thing we have the interwebs to fact check and verify.

I'm also a trusting kind of person, much to my disadvantage sometimes. That's why I put up this thread to get as much first-hand info as I can.

One can't ever rely on all the info given by dealers nowadays.

But, sir, by law, diesel vehicles sold here need only be euro 4 compliant, right? So it's safe to say, majority of brand new diesel vehicles still don't have DPF in the Philippines? No ticking time bomb, here. Not yet.

It depends where the units were assembled. Those coming from Thailand may still be E4s. Those from Japan may all be equipped by now....And them Euro premiums.....those definitely have the bombs strapped.

Manufacturers won't put DPFs when the market does not require it by law ... Unless their volume for that market is too small that would make it more costly to not include it ...
