Very nice. I appreciate the effort that you have put into this. We have some older cars with high mileage (both are throwing P0420 right now) and I have used cataclean in one of them already. It seemed to work for a while, but SHOOT! I think I am going to run a gallon of lacquer thinner next. Maybe it will work better this time. Thanks again for posting all of the lacquer thinner vids!
Just tried the lacquer thinner gallon in my 04 Silverado 5.3 and I put the 1 gallon into about 20 gallons of gas (roughly 3/4 tank) because I was too impatient to bring it down to half a tank (roughly 13 gallons). After running the engine for 15 minutes it cleared all my codes and is running excellent, even at that 20:1 mixture and after watching your test I'm glad I didn't do the 13:1 mixture. Cool test, it's definitely meaningful to see the deterioration this can cause to rubber o rings and seals. To anyone with a check engine light on a car getting P0420 or P0430 codes with an average fuel tank smaller than 20 gallons, I'd highly recommend you do half of the recommended amount of lacquer thinner than typically recommended. Start with half a gallon of thinner in 8-10 gallons of gas and if it doesn't work, many people say you can do a 2nd and third treatment until the cats clean up.
Yes, clean up all depends on condition. If the cat’s internal material has disintegrated numerous treatments won’t clear codes. Catastrophic failures are contributed to punching the gas. Punching it when the cats have a buildup of soot can cause the internal material to blow out. Dirty cats also cause cats to overheat. Overheating weakens the internal material. To avoid catastrophic failure I run lacquer thinner once a year or 15,000 mile intervals. Also avoid punching the gas…

It is pretty close I think. You can get cataclean for a lot less money online though. I got 3 liters (the autoparts store bottle is half a liter), so 6X the product for around $45. I just bought it on Amazon. I figured that I was going to be using it on a bit nicer car, so why not. I've used it on my lawnmower too. Not all lacquer thinner is the same for what it has in it either, where cataclean at least is likely consistent.
Thanks a lot for your effort in producing this knowledge for us all. As 'ínformation' only, rubber O rings {like all rubber} is produced out of latex, carbon, sulfur - and other accelerators and retardants - pretty nuch as they manufacture a "cake"...each one has its OWN recipe! Then, mixed up in what they call a Bambury. Mhen mixed well, they "form" them via an injector or extrusion machine. Once formed, it is "cook" under temperature and pressure. The "curve" deployed at curing time is of most importance, because it "reads" for us, the special characteristic of elasticity and/or reliance to breakage. This is done on an instyrument called Rheometer. All rubber components give off oils and solvants used to dissperse the components during the mix, btw. I think that exposing the rubber briefly to some lacquer thinner, cleaning it afterwards off it, will not harm any part of the vehicle's system, if done fast. Thanks, again. ✔✔
Just a thought but if the orings expand wouldn’t that make a better seal. Also per cataclean’s instructions you put it in at a 1/4 tank then only drive for about 10-15 miles before filling the tank which further dilutes the mixture. I’m having a 420 code on my 04 acura tl and am going to try cataclean for now.
Im not throwing codes, yet. When i hit over 3k rpms i get a smell in the car. Only smell it when the windows are down. Someone said it was dirty cats. I've run 2 bottles of cataclean and it seemed to help a little. Would the thinner be better?
I think it is better but that is up for debate. My neighbor just used Cataclean and it didn’t do anything but the lacquer thinner did. I would try it. I have personally used it on two vehicles with success and no issues.
I used cataclean on my Is250. The code would come on & off. Once I put the lacquer thinner, light never came on. I did 1/2 gal of gas & 1 gallon of lacquer
I have an f150 Ecoboost 3.5L that likes to run rich so it would always kick off the check engine light. Not being a car guy, I thought I'd have to buy a new catalytic converter but researched other less expensive options. Lacquer thinner did the trick, but the light would come back on every other month or two. Though Cataclean might be safer so tried it and it works too. BUT it's so damn expensive that I'm going back to LT. Thanks for the video!!
That is awesome! It is a shame that you have to do that so often with your truck but at least you found a trick that works. You are correct, Cataclean is very expensive. Thanks for the comment.
Techtron Fuel System Cleaner didn't work. Techtron Fuel Injector Cleaner didn't work. Cataclean didn't work. Lacquer Thinner didn't work. It's bank 2 not both so it's an exhaust leak or the cat. Next move will be that O2 sensor trick.
The problem was, I had a power failure over a few days and installed a new battery. The light came on during the trip home. I had to run a 'Drive cycle" which allowed the computer to run a proper systems check. Light went out.
been running my truck on pure lacquer thinner for years now ( lacquer thinner plant next to me give excess to me for free} no codes ever since going 100 percent thiner
Thanks for a well thought out and executed video. As someone with a science and engineering background I appreciate your approach. While strength as a metric of deterioration has some role, it seems to me that compressibility and resilience of the o-rings is more important in this application, so maybe you could look at that sometime. That said, among my cars is a 14 year old 140,000 mile Maxima. I did not have a cat code, but the convertors on those cars are known to clog up and fail. I didn't know about using lacquer thinner at the time, but purchased some cat cleaner snake oil at the local auto parts. Maybe it is just placebo effect, but I swear the exhaust sound became more open and the car is running better. Did I relieve excessive back pressure or is it just my imagination? To be clear, I would not use these products with any regularity (like maybe once every 140,000 miles) but nothing broke and I think it helped. Maybe six months from now it will all fall apart, we'll see. Since it worked so well on this car maybe I should try it on my Tesla? Just have to find the gas cap first. Thanks again for the video.
@@rwizard 😂 great comment. I have other videos where I tried this on cars and it never harmed anything that we could tell. Yes, I’m sure your car is breathing better. Catalytic cleaners have very similar ingredients to lacquer thinner. When you find the gas cap on your Tesla let me know. Thanks for watching and for the comment.
Interesting but wouldn’t you get a more accurate estimate if you mixed it at 32-1? And the o rings inside the engine would have some lubricant coating to?
Yes, all of them that has had LT ran through them have no problems, including my friends that have done the same in their cars. One of them is a 400,000 mile Corolla that used to run rich and now runs great.
If you don’t have any running problems or codes I wouldn’t worry about it. If you have a P0420 code you could try putting a gallon of lacquer thinner in the gas tank with half a tank of gas. Then run the car at highway speeds until the tank is empty. This often helps a car pass emissions testing. If the lacquer thinner doesn’t work you could try removing the cat and cleaning it by soaking in a bucket of water and soap overnight and reinstall.
Kalifornia Klean Strip formula : PROPANONE and GLYCOL ETHERS. 49 State formula :ACETONE,ETHYL ACETATE,METHANOL,PETROLEUM DISTILLATES and TOLUENE.I would be careful about using this in California. Maybe Scotty or another Car Tuber could test this? I"m in California
I have never tried that, mainly because I haven’t had to. If I had to loosen anything up I would probably remove the cat and clean it removed from the car and then reinstall. Thanks for the tip though.
@@duypham76 it would really depend on the vehicle and how hard it is to remove the cat. With a difficult removal you may be able to remove the upstream fuel mixture sensor and pour some in that opening, worth a shot.

You are welcome. If I planned on keeping the car I was going to do the same exact swap, especially because a new cat may do the same thing and kill the engine. Glad you fixed yours permanently. Thank you for the comment.
Thank you for the question. I wouldn’t advise to use lacquer thinner on diesel cars because it would lower the flash point of the fuel and could be dangerous to the engine. Diesels are high compression engines and it is designed to use fuel with a high flash point. Adding lacquer thinner will lower the flash point and possibly cause detonation. Great question.
No that’s not true. The point of o-rings is to keep fuel from squirting out between the injectors and fuel rail. If you take the o-rings out, you will have fuel exiting through the o-ring grooves. When you install the o-rings, the fuel is stopped by the o-rings. I guess he believes there is some sort of force field around the seals.

There is a better way to clean cats. That better way is just like it’s done with diesel fuel emissions systems. It’s illegal to tamper with our emissions systems. Drilling a small hole upstream of the cat. Then spraying carburetor cleaner directly into the cat while engine is running would also clean the cat. Dirty cats are the issue, how to clean them is the controversy. No one would disagree that there are better ways to clean cats. Until those better ways aren’t considered tampering or illegal. We are left with mixing lacquer thinner in the fuel tank. Removing the cat then cleaning it is the hardest way. The P420 is common, it’s a money maker. The lacquer thinner treatment doesn’t make any money for those in the replacement business. It’s almost like the industry pretends soot and grime shouldn’t happen in a gasoline cat, but it does. If it clogs up enough, you will blow out the internal material causing a catastrophic failure. Overheating of the cat is also contributed to soot. I don’t wait for the P420 I now run lacquer thinner around 15,000 mile intervals. My scanner tells me it works… My scanner also indicates the emissions system works better with overdrive off in city. Overdrive off in stop and go city driving will help in preventing soot buildup. Overdrive on while driving on interstate above 60mph if very fine indeed…
@@enthused7591 with half gallon, you could mix with 5-8 gallons just under or at a quarter tank. I haven’t had any sputtering or hesitation. Drive on highway with overdrive off. After about 30 miles slow down then punch a few times to power clean. Note; punching it can cause the internal material to fall apart if it’s weak. So, avoid punching the gas, it’s a lot of pressure for the cats to deal with… Run out as much as possible before refilling. Don’t mix then wait a day or week. Not a good idea letting it sit around…
