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.
