How often should I clear out my car's DPF?

How often do you have to drive hard to burn soot off the DPF?

Hi John,

It depends on your driving style and where and how you do most of your driving. If you’re mostly or always in town and at low speeds, I’d recommend at least once a month taking the car out for a good run up the motorway, alternating between fourth, fifth and sixth gear if the car has one, and do so for about 20-30 minutes. If you’re regularly driving for stints on the motorway at 120km/h then don’t worry, you’re already doing enough to keep the DPF clear.
