Cataclean 6160 Diesel DPF & Catalytic Converter Cleaner, Diesel, 500ml

One thing you have to understand. A bad catalytic converter code does not necessarily mean a bad catalytic converter, but if your converter is truly bad, this will not fix it. It will fix dirty O2 sensers or excessive carbon build up inside the converter... If that honeycomb metal Is melted inside... Should I say more?

Thought for 35 bucks I was getting the 6 pack case that’s in the photos. Take the photo of the case off of the picture of product. If I would of known it was one bottle I would of never spent that much on it.

Excellent and reliable product; can tell the difference after one use. Quieter engine, smoother and more powerful. Be careful because it is too strong; you might get some SCR-related errors (check engine), which might require a diagnostic tool to reset.

Absolutely brilliant product, product works as described and quality of product is excellent.

Fantastic, go really well with a DPF regen, smoked the place out but now my DPF clean. Always get when on offer as its worth the money

Fantastic i shall say Used as instructions says Ran the fuel to the end and noticed MPG increase Car has more quicker acceleration and goes up the hill 3rd which wasn't case before Engine sounds a lot crisp I would say if the price was £6 Mark would be definitely 5 stars It reminded me of Redex in olden days when it was magical but now CATACLEAN all day long Strongly recommend it I have used in my Diesel 1.4 and very happy next be my Peteol Car too *Please use as instructions and run it down before fill up

Highly recommend for your diesel. On putting into less than 1/4 tank and driving 20 miles before filling up, instantly feel the difference in acceleration. Living in wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿 we’re getting increasingly more rain and slow speed limits, so whatever this does to protect fuel lines from the damp environment, it’s working. Taking care of our 28 year old vw t4 from the tank onwards through the system. After checking the blanked egr several months after using it, I can confirm it is definitely cleaner than before plus the hills are easier and the take off acceleration is noticeably better too.
