I have to comment on this!!! My daughter's 2013 Ford flex has had it's check engine light on and it's time for inspection. The codes say both catalytic front and back are bad. I contacted my mechanic he quoted me a repair price of 1700.00 dollars. Ouch. I have been looking for a way out. So I heard about cataclean. Yesterday I put cataclean in a fourth of a tank of gas. I reset the computer by disconnecting and reconnecting the battery. The flex resets the computer after you drive 85 miles. I got on the hyway and drove 100 miles straight stomping the gas from time to time, putting the engine in passing gear to force cataclean past ignition into the catalytic converter. At 85 miles the check engine light DID NOT COME ON. At 100 mile no check engine light. I drove to inspection station. IT PASSED INSPECTION. IM IN SHOCK IT WORKED COST 25 DOLLARS TO SAVE ME 1700.00. IT WORKED.

[@mudhawg8849]

This stuff does work. But you have to use it as it says. The 1/4 tank part and driving afterwards is very important. 1 part they dont mention is that it helps to drive the vehicle with more of a lead foot then normal. Dont drive it like its the last lap at of the 500 but get the rpms up which will in turn heat up the system and force the crap out of cats and exhaust aswell as increase the injector latency and duty cycle. This stuff, seafoam and crc maf cleaner are 3 of the best products on the market for people to save hundreds if not thousands on stuff that can be done at home in 30 min

In the process of waiting for a 2009 Honda Pilot results. Had codes P0420 & P0430, on a close to empty tank filled it up with a similar brand called Dura Lube and filled up the tank. That's really helpful that you have that live data scanner that narrowed it down to a specific oxygen sensor. I remember when I used to work at a small car lot, removing and cleaning the oxygen sensors with a grinder would also help clear the codes at times.

[@luismelendez1761]

I just bought one and I going to try, I see other comment and it since to be working, thanks for your video, God bless ytou.

[@luismelendez1761]

It works

[@SnowAngelfish]

Update: So I tried it and it really worked! At least for long enough for the car to pass emissions and be registered. Then after 200 miles the same check engine light with code P0420 came back on. So I have to say the fact it went 200 miles before coming back on was very impressive and makes me think it helped clean it a bit because in past it would come on after 40-50 miles . This 2003 corolla has over 250k miles so im sure theres a lot of carbon caked on in there! Im gonna run another treatment of it through and we are going to run one bottle a year in our toyota van also as preventative maintenance in hopes it prevents us from ever having the same issue. So while i was skeptical at first,, In the end im quite impressed and for 27 dollars it was definitely worth trying it and Id recommend it. In addition the car accelerates better too so it ay have also cleaned the fuel injectors. And hopefully with a few more treatments enough carbon will be cleaned out of the cat and the issue goes away.

[@billyde5933]

My wife has a 2009 Jeep Rubicon. Needed to get an inspection but the engine light came on. Bad Cat... so... I asked the mechanic if I could just pick up a replacement cat. He said you can try. So I found one for 230 bucks. Oops, not for this Wrangler. (built in California)(very strict ) It has 4, yes 4 cats, 2 in front Left Right, two in the rear Left right. The right front was giving the code. I said well can't we just replace that one ? So I checked with a local dealer shop. They said you have to replace the entire exhaust on that vehicle. It comes all in one piece. Oh crap... Well how much is that ? $6500.00 WHAT ?!?!?? Good thing I was sitting down. That doesn't include labor. We can't afford that. So being there was only a week left on the current inspection, I did some research scrambling and discovered CATACLEAN. It has to be worth the try. I did it. the product worked clearing the engine light. Took it back to the mechanic and he says WOW. Passed inspection. Unfortunate after a month the engine light came back on. Time to order more. With the engine light on, my wife can't remote start. Being it is a cold winter here on Long Island, and she heads in very early to work, I will have to maintain her ability to warm up before going out into the freezing temps. Thanks Cataclean, you saved us. several thousand dollars. But now I gotta buy more. (sad).

Worked in a BMW show for a very long time. I feel the need to chime in and say that these cats will last forever and only foul due to emissions systems that have been tampered with or neglected.

When it does go in limp mode, it dont cut off, but it will get down to about 20 mph.

Hey guys good info you spreading. I got a question of my own. Exhaust back presure sensor went bad. B class 180 2014. Ill replace it soon.

Give me a quick thought please.

As far as I know catalytic converter works neutralizing exhaust gases through a hot chemical reaction because of the compounds of what it's made of, so, you cannot clean that, so I believe what you're actually doing is cleaning the fuel system, fuel tank, valve seats, injectors and ducts, cleaner fuel system, cleaner combustion, better readings.

this product does work and will help to clean cats for passing inspection or prevent huge repair bill. however, the downstream oxygen sensor or sensor 2 only monitors the health of the cat, it does nothing for fuel economy.

Probably because lacquer thinner is designed for thining lacquer and not for being run through a cars fuel and exhaust systems. Whereas cataclean is solely designed and made for just that 🤷‍♂️

My check engine light stay at all for like 20 minutes cuz I turned it off by the computer the scan tool put it in half tank put it back more gas after I got done driving the vehicle yes still on the engine light

[@PositiveMindframe24]

Oh snap! Okay. I just put a fuel injector cleaner in and filled up my tank. Should I let my tank get to half, then add the cataclean?

[@siuflsr]

According to this guy you let it get to 1/4 tank and add the whole bottle. drive 10 to 15 miles and then fill your tank up.

Don’t you love it. The o2 sensors are part of the issue. I’m a women however I do major research. I called around auto parts store ti check prices for sensors which quoted260.00. I just had it diagnosed because it had a code that had several issues…I have a reader so I’m aware of it. The shop charged 100.00 and said we will start with o2 sensors. Oops sorry boys, the O’Reilly parts man suggested this product so guess what I’m going to do‼️‼️‼️👏👏👏 I’m getting some and going to follow the instructions from this video and clean things up so I don’t have to replace sensors. I drive the other German car.. 🚗.. Smart car Thats unfortunately not so smart. I actually know more about these cars than Mercedes does. I’ve had issues with the clutch actuator and had it fixed.. THANKS TO KZbin again and again‼️.. I can’t wait to see how it works on my car. When it runs good I can get at least 50 miles ti the gallon on hwy.. and that is with additive. Marvels mystery oil works good. Thanks guys for your video‼️‼️ I bet you are saving people LOTS of $$$$$$$. I o we need a 1989 325i fir 15 years so I know how much repairs can be even at a ship that undercut others but still did a good job‼️‼️

[@rebekahcurtis1996]

So is this just something to use to get you by until you can actually afford to get that catalytic converter replaced??

[@bassplayer536]

Used cataclean on my daughter’s 2010 accord…check engine light cleared itself 41 miles after I filled the tank…dealership told us we needed a new cat and wanted to charge us 3k…I’m a huge skeptic but I saw it with my own eyes…may not work for everyone but it did for me 🤷‍♂️

[@lh98]

@bassplayer536 do you know what code number it was? Still good 2 weeks later?

[@burhan5944]

I used but it didnt work so can a repair Clean my convertor or I have to buy new one?

[@bitshtannicajohnson6957]

*Pour abottle of 140 weight oil in it directly, then go for a long scenic drive - and watch the amazing results!*

[@user-nv1gm2zj7y]

nothing can repair a cat. you replace it and its expensive cause its made with raremetals like palladium

[@DFJ1997]

I've seen guys use air to blow out catalytic converters, and it works just fine.

[@MikeKollin]

Can you buy this at Auto Zone or O'Reilly's.... ?

[@inangekah2090]

O'Reilly sells it

I had a po420 error code in my cobalt, added some Marvel Mystery Oil and took it for a 70 trip, cleared the PO420 code and it is running great with no codes.

Added MMO to the fuel or oil?

Lacquer thinner works just as well.

[@jessies6502]

I was going to try this, but then read that it can destroy your gaskets?? I was going to try the Cataclean first, because of that.

Stuff likenthiw is just a bandaid who knows how long it will help or how many times it can or will help but eventually the light will reappear and eventually those cats will either have to go or be replaced.

[@Ryan.the.saiyan]

For how long will this work without actually replacement?

[@scottreneer5982]

I got 24 days of driving before same code came up. Broke down and got a new CAT for my 2015 chevy equinox 2.4. Code been gone since

[@tamraharvey9799]

I have a 2008 Jeep liberty do you think it’s gonna work for that?

[@tamraharvey9799]

It will not go past 4000 RPMs I just changed one of my oxygen O2 center and it’s still doing the same thing. It’s like I got a lot of hesitation when I give it gas like putters my check engine light flashes so you telling me this stuff will work good.

[@dazone]

what scanner is that?

[@claytonshields1820]

Looks like the more expensive bigger autel maxisys
