Product Description
Is your DPF warning light on? Your diesel is trying to tell you something
Modern diesel engines trap soot in the Diesel Particulate Filter (DPF) to reduce emissions. But short trips, city driving, and poor fuel quality prevent the filter from reaching the high temperatures needed to burn that soot off naturally. The result: a clogged DPF, a warning light on your dashboard, reduced power, and — if left untreated — an expensive garage bill or an automatic MOT failure.
XADO AtomEX DPF Cleaner & Restorer is a high‑strength fuel additive powered by proprietary XADO Revitalizant® technology and advanced combustion catalysts. It lowers the burn‑off temperature of soot particles, allowing your DPF to regenerate effectively during normal driving — without removal, specialist equipment, or unnecessary component wear. It is ideal for vehicles showing early signs of restriction, reduced power, or frequent regeneration cycles.
Signs Your DPF Needs Attention Now
- DPF warning light or “Check Engine” light illuminated on the dashboard
- Noticeable loss of power, sluggish acceleration, or engine entering limp mode
- Higher fuel consumption than usual
- Frequent, incomplete, or failed regeneration cycles
- Excessive or black exhaust smoke
- Cooling fan running continuously after engine shutdown
- Rough idle or a strong, unusual diesel smell
Why Do Diesel Particulate Filters Block Up?
Modern diesels produce fine soot that must be trapped and periodically burned off within the particulate filter. Short trips, low‑speed city driving, and low-quality fuel prevent the exhaust system from reaching the high temperatures required for natural regeneration. As soot accumulates, back‑pressure rises, causing severe engine restriction. AtomEX chemically lowers the burn‑off temperature of this soot, allowing the DPF to clean itself effectively even during standard driving routines, while the integrated XADO Revitalizant® provides active anti-wear protection for high-pressure fuel components during the cleanup process.
How AtomEX Restores Your Engine
-
Cleans Without Dismantling: Safely clears the diesel particulate filter without expensive garage teardowns.
-
XADO Revitalizant® Protection: Utilises our proprietary metal‑ceramic rebuilding chemistry to coat and protect critical fuel system and injection components from friction and wear during treatment.
-
Restores Lost Performance: Instantly improves exhaust flow, restoring throttle response, engine power, and fuel efficiency.
-
Prevents Costly Repairs: Helps prevent catastrophic limp‑mode events, active dashboard warnings, and avoids forced workshop regeneration or DPF replacement.
-
Optimises Regens: Reduces regeneration frequency and supports faster, cleaner, and more complete burn cycles.
-
100% Safe Formula: Fully compatible with all diesel mechanical elements, injection styles (including Common Rail and Pumpe Düse), and exhaust after‑treatment systems.
What to Expect: Before & After Treatment
Before Treatment:
- Sluggish acceleration and loss of engine power
- Frequent or failed regeneration cycles
- Active DPF warning lights on the dash
- Unusually high fuel consumption
After Treatment:
- Smoother, more responsive driving and performance
- Fewer, more efficient regeneration cycles
- Restored power and cleaner exhaust flow
- Improved fuel efficiency with ongoing component protection
How to Use
- Wait until your fuel tank is low (approximately ¼ tank remaining).
- Pour the entire 225 ml can into the fuel tank immediately before refuelling to ensure proper mixing.
- Fill up with diesel as normal (ensuring at least half a tank to a full tank).
- Drive normally; the additive works during regular operation.
-
For Best Results: Take the vehicle for a steady 15–20 minute drive (approx. 20–30 miles) at operating temperature on an A‑road or motorway. Where safe, keep the engine above 2,500–3,000 RPM for short bursts to help trigger passive regeneration.
- Use every 3,000–5,000 miles (approx. 5,000 km) as preventative maintenance, or immediately when warning symptoms appear.
Driving Tips for Best Results: Ensure the engine reaches full operating temperature before pushing the RPMs. Maintain a steady speed on open roads, avoid short stop‑start trips immediately after adding the treatment, and use high‑quality diesel fuel where possible to minimize future soot buildup.

Frequently Asked Questions
Will this fix a completely blocked DPF?
This product is designed for early to mid‑stage blockages, poor regeneration cycles, and preventative maintenance. If your filter is severely overloaded or the vehicle has locked into a hard limp‑mode, a forced workshop regeneration or manual physical clean may be required alongside this treatment.
Can I use this to pass my MOT?
Yes — a blocked or poorly regenerating DPF is a common cause of MOT emissions failure. Using AtomEX before your test (ideally 1–2 tanks prior) can help reduce soot levels and improve natural regeneration. Read our full guide: Why cars fail MOT on emissions and how to fix it.
How is this different from just doing a long motorway run?
A motorway run raises exhaust temperatures to trigger passive regeneration, but it only works if soot levels aren't already too high. AtomEX actively lowers the chemical temperature required to burn off the soot inside your filter, making the cleanup process far more effective—even at lower driving speeds.
Is it safe for my engine, and can I use it with other additives?
Yes, the formula is 100% compatible with all diesel mechanical elements and exhaust after‑treatment components. While safe to mix, we recommend using AtomEX on its own fuel cycle for the first treatment to maximize its targeted cleaning performance.
