A diesel particulate filter traps soot and burns it off during a regeneration cycle. Stop-and-go delivery work rarely gets the exhaust hot enough to complete that cycle, so soot builds up, back pressure climbs, and the van loses power. A forced regen or an oven cleaning restores flow.

## Why Delivery Vans Clog Faster

Passive regeneration needs sustained highway heat. A van doing dozens of short Inland Empire stops a day never reaches it, so the filter loads up and the control unit keeps trying and failing to regen, which also dilutes the oil with fuel.

## Forced Regen Versus Oven Cleaning

- A forced regen with Xentry can recover a filter that is loaded but not blocked
- A fully blocked or ash-laden filter needs removal and thermal oven cleaning
- We measure back pressure and soot load first so you pay for the right service, not both
> If the van keeps re-clogging, the fix is often upstream. We check the injectors, EGR, and turbo so the DPF is not just cleaned but kept clean.
