Wynns WY28272 Diesel Particulate Filter Cleaner, 325 ml

After 3 failed regenerations at dealer, tried this today on my 2 year old Nissan Note 1.5 diesel. Nissan Customer Service is a complete joke, not honouring warranty, claiming DPF blockage is down to driving style, even though my vehicle is high mileage and does frequent motoway trips. Needless to say, I won't ever buy a Nissan again. Anyway, the verdict? It works! I had an engine management light constantly on and also a flashing auto start/stop. Car would 'hesitate' under heavy acceleration. Had half a tank of fuel remaining. Added all of bottle to tank, and then filled up the remaining half of the tank with some Shell V-diesel. Gave my car a good thrashing on the motorway (keeping revs above 3000rpm using 3rd and 4th gear). After 80 miles or so and a quick toilet stop the start/stop light disappeared and full engine response was returned. Took the car for a further 40 miles or so. But engine management light still on. Took the car out again in the afternoon after a 3 hour break and did another 30 miles on the motorway. Went home, had a cup of tea and started the car up again and bingo - engine management light also gone! So, I'm very pleased! I don't normally write reviews, but thought this might help someone else. And please, don't ever buy a Nissan.

Paid £45 to have my filter regenerated at Garage, but (whilst on holiday trip) light showed again after 1500 miles and low power kicked in. Decided to try this cleaner, did 50 miles on motorway, power improved but light stayed on made return journey of 50 miles on motorway by the end of which power was much improved, but light stayed on. Next day headed for home on motorway, power continued to improve light still on. Stopped for a cuppa, on restarting engine light was off. After a further 2000 miles light is still off and car is nippy and responsive to the throttle. Will be adding this to my next tank of diesel. I regularly make a round trip of 36 miles with most of it having 40 and 30mph restrictions, I now drive these in 4th (40) and 3rd (30) gear which keeps my revs over 1500 which I understand helps to keep the filter cleaner.

Not sure if it does anything or not as car seems exactly the same but perhaps it was okay in the first place.

The Car went on Limp Mode ( Restricted Power ) Due DPF Choked up due to Too much Short Cold Engine's Run's, Poured in a Bottle of DPF Cleaner into Fuel Tank ( Make sure there is a Decent amount of Fuel in Tank. Min Half a Tank ) Went on a Long Run ( Dual Carriage way is Best ) Keeping Engine at a Warmer Temp and the DPF Cleaner and Warmer Engine Dislodged all the Build up in the Engine DPF. Car Driving Normal Now but will have to take it to a Garage to Cancel the DPF Trouble Code Light on Dash as it came on when Filter became Choked but even with DPF Light on, It still Dive's Fine.

I couldn't possibly say whether it made a positive difference or not. My DPF was in reasonable condition for an eight year old car when it was last checked by a mechanic a year ago. I ran a bottle of this through as a service/precautionary measure a year later just to try to keep it as clear as possible (it's approaching the mileage where the manufacturer suggests a DPF replacement). There were no obvious performance issues with the car or warning lights at the time so nothing to measure an improvement in. I have not noticed any difference at all since using the product either. A small note of caution, though, in case it helps to feed into a bigger picture. Something odd happened barely 48rs after putting this stuff in the fuel tank. I put it in on a Sunday, drove to and from work (42 mile round trip) the following day and everything felt normal. Ten miles into my journey to work the following morning, though, my car completely cut out as I accelerated off a roundabout on a dual carriageway. I pulled over for a moment then started the ignition and the same thing happened as I pulled away. I coasted into a lay-by and gave it five minutes then drove the remaining few miles gingerly. All was fine on the way home and it hasn't happened again since. This is the only time it has happened in this car and it's just the timing that seems a bit coincidental.

For months if not years my 53 plate Peugeot 307 Hdi had been nagging me to 'Unblock Diesel Filter' and 'Antipollution Fault' due to the car only doing short runs. I tried the regeneration method but that didn't work and put the car temporarily into limp home mode restricting RPM 2500. I was advised by my local garage that the problem was largely due to cheap supermarket diesel which I've always used and switch to the premium stuff and that the Particulate Filter Cleaner was certainly worth a try. I've now driven about 100 miles since filling the tank with good stuff combined with the additive and the error messages have stopped for now and engine performance seems improved. Hopefully it will continue this way.

Waste of money

After 4 days my DPF problem has been resolved. I have had two previous Citroen Picasso diesels with no problems. However, my latest model is rated at a lower emissions level, and really does need to be driven more aggressively in lower gears to increase the revs. Since adding this product, I have been able to go back to my former frugal type of driving. We are seduced into buying a diesel with the promise of many more miles to the gallon. However, this all goes out the window if you have to periodically "thrash" the engine for a few miles to prevent a DPR blockage. I intend to add this product to every 3rd tank of fuel as a preventative measure.

eccellente qualità/prezzo

Reçu en décembre 2025. Le produit est périmé depuis 2022!

A verser directement dans le réservoir. Perso, j’ai utilisé le flacon pour moitié en respectant le dosage, soit 30l de gas-oil. Un trajet sur autoroute à vitesse constante, en montant un peu plus dans les tours (2600t/mn pour mon moteur) en restant en 5ème. 100km après, le voyant orange s'est éteint, je suppose que mon FAP est nettoyé. En tous cas, je suis revenu aujourd'hui à une consommation normale. Au cas où, j'utiliserai l’autre moitié du flacon 😉

Impeccable

Seit dem ich diesen Zusatz ab und zu in den Tank schütte, läuft die Regenerierung und der Motor einwandfrei... Fahrzeug: BMW X5 3.0
