DPF Filter Purge Additive 2-Pack — Diesel Particulate Filter Cleaner & Protector | Reduces Regen Cycles, Cleans Soot | for All Diesel Engines, 16.9 fl oz Each

I guess it worked I was getting regens frequently then poured this in with 1/2 take of diesel so it was nice and concentrated. Drove like normal and boom!

Seams to help keep filter clean ? Least by truck panel .keeps reading o per cent dirty

Have not had any issues. Am getting fewer "Filter regeneration" notices so maybe this helped.

Easy to use, adds right to diesel fuel. Drive your truck at higher rpm’s in lower gears. Get on the highway and let it eat, haven’t had an issue

I'm gonna give it a 4 star, because if my catalytic converter was clogged, it probably would have worked. It was easy to use and Highly recommended as one of the best. If, in fact, your catalytic converter is clogged, sometimes they just get old and what they are supposed to do depends on the chemical reaction. For me, it was worth the money to try it.

I tried this product when my diesel NH farm tractor was going to regen mode more frequently and from what I can tell there has been noticeable improvement. I’m not crazy about the newer tractors exhaust systems and this product seems like a good idea to maintain them and hopefully reduce the future repairs associated with .

I have 2022 Ram 2500. My check engine light came on and the code it gave was for the re-gen frequency. I tried several times to clear it and it wouldn’t go away. I bought this product just as a “what do I have to lose” scenario. I didn’t have high hopes that it would really do anything. Boy was I wrong! I had about a 1/4 tank of fuel and I poured a bottle of this is and ran it all but dry. Lo and behold it cleaned things out as advertised, the re-gens stopped, and the check engine light went off! I still have a full bottle left in case it were to happen again. $40 saved me what undoubtedly would have been hundreds or even thousands if I had taken it to the dealership. Great value for the money and worked super fast! Highly recommend! What do you have to lose?!?!

Not sure if it really did anything, didn't notice any changes? So jury still out. Drove 700 miles used both cans.

It really works!

Wow this product is amazing it solved my forced manual regen issues after half a tank. The truck runs better.

Ce produit ne sert a rien je l'ai mis ds ma Mercedes-Benz ml 320 bluetec diesel 2009 ou w 164 Je n'ai pas vue la différence Ce produit est a 0

Used up all two bottles. Did nothing even after forcing regens. DPF will have to be removed and cleaned. Waste of money. Hopefully cleaned injectors at least.
