    So I used it on my 2008 Nissan Sentra 2.0 a few hrs ago. Poured it at 1/4 tank of gas then drove at least 14-17 miles as instructed. Refueled and drove back. Stopped by to get something to eat and an HR later I turned my car on and the check engine light didn't come on anymore. 😁

    Correct. It will clean up contamination on the cat or O2 sensors if the source of that contamination is addressed. I had antifreeze contamination from a small leak in the head gasket. Once that was fixed, the code would not clear off since antifreeze had coated the components. This will clean off residue and clear the CEL.

    i just used this stuff last night and it worked amazingly!! my 2015 ford focus came up with a P0420 code, so i went and bought the cata cleaner from my autozone and my check engine light was gone when i woke up the next morning. The best part about everything, is that because I have a capless gas tank, my first attempt using this resulted in half the bottle spilling out onto the ground, yet the product still worked for me. Although, since I wasted half a bottle, I will be going back to the store to do another half treatment. However, it doesn’t seem entirely necessary because it worked that great the first time!! (Note: if you also have a capless gas tank, you might find the buttons to release the opening on either side of the hole. i used a screwdriver to push them in, and then had a funnel ready to hold the hole open and pour the product straight in)

    I thought this stuff was going to be the definition of snake oil when i first tried it. I followed the instructions cleared the code before putting it in my tank. Drove for about an hour and Out of nowhere my engine light dissapeared. even felt a slight sputter in my fuel system when it happened was kind of weird but saved me $1,200. My last test the Cataclean did not work right away but i used Octane Boost after as well as some Marvel Mystery Oil and after a few days my system was Clean. My Cat was changed 6 years ago may be an 02 sensor or on the way out but again i would try this and from experience other additives are helpful as well.

    I just tried this on my 2005 Toyota Corolla a few days ago. My check engine light came on with the code P0420. I found this video and figured I'd give it a try. I poured it in, I had just under a quarter tank. I drove for about 16-17 miles, stopped at a gas station and got gas. When I turned the car back on, the check engine light was off already. It worked so fast, I can't tell you how surprised I was. Still am 🤣 I also feel like I might have better gas mileage than before. The needle doesn't seem to be dropping as fast as it used to 😅

    I bought a 2012 kia soul 1.6 with 160,000 miles on from Facebook marketplace. The seller cleared the check engine light but did tell me the check engine light comes on sometimes and didn't look into it. More than likely he did find out and put the car for sale. Before buying the kia soul, I test drove it for 30 minutes and nothing. Drove 2 hours to pick up the car. I went to valvoline instan oil change for them to look at the car and make sure everything was fine. No leaks or nothing broken under the car. So they said, car was in good condition so I bought the car, paid cash, 3,000 cash. It has AC, transmission shifts okay, no burning oil, car seems to be in good shape. But when I got home and had to move the car, the check engine light came on. Went to autozone to check the code. It was the catalytic converter. I added Cataclean twice and the check engine light still returns. My guess is the seller drove it too long with the catalytic converter clogged up that it is too late to clean it using cataclean. I'm going to replace the catalytic converter tomorrow but will keep the old one to see how bad it is and see if I can clean it. The kia soul is GDI engine, (Gets destroyed immediately) if driven with the check engine light. A new catalytic converter from kia is 1,790 dollars plus 3 hour installation, taxes and fees so close to 3,000 dollars. But like I said, I've tried to run cataclean twice and didn't work so I will get an aftermarket catalytic converter installed tomorrow but will keep the old one for inspection and possibly clean it as good as new as long as I'm able to desolve or breakdown all the carbon built up inside the honeycomb. The honeycomb is made put of titanium metal, but an aftermarket is made out of cheaper metal, more like chicken wire metal that's why they're cheaper. The only way to find out why the catalytic converter failed is by removing and doing a visual inspection. I don't notice anything else wrong with the car, no coolant leak, no white smoke, no black smoke, it drives okay but I do notice fuel economy is not so good, it is not that great so I believe engint is running rich. So for my case, it is too late to use this product and need to see what in what state my my catalytic converter is. That's why the car was for sale and only 3,000. The seller didn't tell me because it would be 2,000 dollars and I would probably not buy it. The seller was just lucky the check engine light didn't come on. Thanks for sharing this video

    Sometimes it will fix your P0420 catalytic converter below efficiency CEL.. but an extender in the farthest downstream O2 bung will always make that light go away. If your parts store doesn't have them or won't volunteer the information you can always ask for a spark plug non fouler and then drill it out to fit your O2 sensor. Usually a 1/2" drill bit.. just make sure you stay out of the internal threads with your bit. And then remove the old downstream sensor and install this and then install your sensor in this. You're adding oxygen. Your upstream sensor provides fuel trim but your downstream just tests how effective the catalyst is. So this morning when I seen the CEL I pulled out my tester, plugged in, and found catalyst below efficiency. So eventually I'll replace the cat with a universal at an exhaust shop.. some people straight pipe them... but the cat is actually part of your quiet exhaust. So I probably wouldn't go for it. My truck is loud enough like it is with a glass pack. I'll spend those pennies on a governor transducer and solenoid and dual solenoid TCC and OD while I have the pan off..I guess readjust the bands or take it to my favorite transmission shop (they actually fix and not just replace!)..I just need a 60 deg day. Until then I will just drive it gently. So anyway if you try cataclean follow the instructions! Don't just add it like a treatment on a full tank. Some people will drop their exhaust and soak in soap and water or lacquer thinner... this and that..I wouldn't.. that's pretty labor intensive and sometimes that method doesn't work either. Oh...it sometimes will also fix P0430... that's bank 2 if you have a bank 2.

    If this is found it would fail emissions in most states and is considered illegal in several states. They do prevent the code from being displaced and may result in worse fuel economy. If the catalytic converter becomes very fouled it will make the car sluggish and difficult to accelerate as the engine exhaust will become restricted in the catalytic converter.

Grabbed a bottle of this and grabbed four sensors just to have them in case one of them fails down the road. I noticed after driving around and putting this in the van does not seem zlightly sluggish like it was when the light went on. I also have that same code reader but it is the harbor freight brand. Exact same one. Deleted the code just like you do and have not drove enough yet to put it back on and check to see if the permanent code has cleared yet. Hopefully I get lucky like you do and I can just take the four sensors back as well.

This will be a temporary solution that may work for a few months and then be needed again. My piston rings and PCV vale are likely causes of extra oil burning which causes the O2 sensors and Catalytic converter to become fouled. I just changed out the PCV valve and will need to change out the low tension piston rings to stop the carbon build up otherwise this will just keep happening.

    @@hamzababli678 a catalytic is not just a air cleaner, its also a O2 storage device. what the ECU measures is not just the changing of the O2 sensor voltage but also the time it takes to change from the first O2 to the 2nd O2. if you can remove the code by running the cleaner then you are at the borderline of its lowest limits. at this point it will be sensitive to the kind of oil and the kind of gas you use. if your car is burning oil, then it will further deteriorate the catalytic. cleaning with the cleaner is just keeping things at bay. so i suspect there is still some issue you have to fix. all this assumes you still have original OEM catalytic. aftermarket catalytic are not as good as OEM. in my case, the engines has been burning oil for more than 100k mi. i took care of that with piston ring replacement, and even tho my cars are at the borderline, the code hasn't come back yet. i have 4 cars like this. good luck! oh i forgot to mention. a generic code reader will not show you the O2 storage reading. you need a OEM software to do that.

    It is a temporary fix to pass emissions and / or get some engine power back and buy some time. Even if you replace the Cat you will want to fix the real issue causing the failure and fouling up the O2 and Cat. I have seen a lot of cars consuming / burning oil due to carbon build up/low tension piston rings/stuck PCV valves or just incomplete combustion with dirty fuel injectors old spark plugs etc. Most manufactures recommend some fuel cleaning additive a couple of times per year such as Techron ( amzn.to/3Yl3orA ) or similar products.

    This could be caused by multiple problems such as a bad fuel to air ratio resulting in too much gas. This could be from fuel not being fully burned off. This could be from an exhaust leak. This could be a bad catalytic converter. I would suggest tuning the engine first for air/fuel mix, make sure spark plugs are good, air filter is not clogged, etc. I am not sure how much this product will help depending on the cause of your issue other than to help clean the fuel injectors to help more of the fuel to burn and remove some carbon deposits in the engine and exhaust. If it smells like bad eggs then you have hydrogen sulfide from partially burned fuel.

    I have used fuel additives to put off buying and replacing my catalytic converter for about two years now as I know I have an oil consumption issue with this engine. I just passed emissions just barely last month and I will need to replace the catalytic converter sometime this year. This is a good product to buy some time, but eventually you will need to address the cause of the fouling catalytic converter and then replace the catalytic converter. If you do not fix the cause the new catalytic converter will also fail.

    If you try this and it works just understand that all you did was buy yourself some time. You aren’t actually “fixing” anything by doing this. Also know that if your motor has a lot of carbon buildup then using this could potentially make the clog worse. This definitely can help and I’ve seen it myself, but it’s short term. Your cat became clogged for a reason, so you need to figure out what caused that. But depending on your situation a bottle of this every six months might be preferable to replacing the cat.

    I fully agree that this is a temporary solution at best and the root cause will still need to be fixed. I use it to help pass inspection / emissions. My issue is that the low tension piston rings allow a lot of oil to burn in the engine. I burn through a quart of oil every 1,000-1,500 miles or so which is fouling the catalytic converter. Replacing the PCV valve helped reduce the amount of oil consumption but it still burns more oil than I would have expected.
