MotorPower Care Best Cleaning Solution for The Diesel Particulate Filter DPF
The Latest foam cleaning technology targets soot and carbon buildup inside the DPF without disassembly. Best for professional-grade cleaning scenarios and diesel facilities that require dependable, quick-acting results. The kit is designed to be easy to use, potentially saving time and money compared with disassembly cleanings. Best for professionals and fleet maintenance operations.
Best for: professional shops and diesel specialists who want a no-disassembly, fast cleaning option. Limits: following the kit’s cleaning steps is essential for effectiveness; results depend on proper use.
MotorPower Care DPF Filter Purge Additive 2-Pack
This two-pack diesel additive approach helps maintain DPF cleanliness and may reduce regen cycles. It’s particularly attractive for daily drivers and mixed fleet use where periodic maintenance is essential to sustaining DPF performance.

Limitation: 500 ml may require multiple applications for larger fleets or severely clogged DPFs.
Buying Guide: Key Purchase Considerations
- Vehicle type and engine: diesel-only vs. hybrids or gasoline-hybrids; check DPF compatibility with your vehicle’s emissions system.
- Cleaning vs. maintenance: choose a cleaner for a one-time deep clean or ongoing maintenance to minimize regen events.
- Disassembly necessity: foam cleaners often require no removal, while some products expect sensor access or certain ports.
- Application method: spray foam, purge additives, or dedicated purge formulations; confirm compatibility with your DPF design (closed/open, DOC/DPF configurations).
- Volume and frequency: larger fleets may require multi-bottle plans; consider refill needs and recommended usage intervals.
- Vehicle warranty considerations: ensure chosen products are compatible with warranty terms and do not trigger warranty voids.
- Safety and ventilation: follow label instructions; perform treatments in a well-ventilated area and wear appropriate safety gear.
