Does Lacquer Thinner Clean Catalytic Converters? -EricTheCarGuy

[@whoward5496]

Im not a mechanic, so I needed help with my CC's since I had the code. I followed Scottys advice using 1 gallon of lacquer thinner in a half tank of gas. Then I ran it for 150 miles at high speeds. The red light went out after the first day never to return. This was performed on a 2004 Nissan Murano. It worked beautifully. I just wanted people to know that it worked for me.

[@craiglist308]

how long did it work for

[@whoward5496]

@@craiglist308 I kept the car about another year before trading it in so I’m not sure how long it lasted, but at least for that year or so. I imagine it lasted much longer than a year though. I was so happy it worked because replacing the CC’s on the Murano was very costly (2400.00). Money that I didn’t have then.

[@martyshimp871]

As a person who is 53 years old and has worked on engines since age 10, I thought the suggestion of lacquer thinner in my gas tank was crazy. Our 2005 Toyota Sienna had the check engine light on and had just failed the PA emissions test. The Toyota dealer wanted over $1300.00 to replace the 2 converters on our van. I was planning on doing the job myself but i read on the internet about cleaning them. The more I read about this working for a lot of people and after considering what chemicals are in intake cleaner, I decided to try it. I added 1 gallon of thinner to 10 gallons of gas and we ran that through. Light still on. I thought that the van ran the same with the thinner as normal so I tried the process a second time. Within 2 days, the light went out on its own. it had been on for 9 months straight before the thinner. Definitely, something positive has happened with the thinner. Moral of the story, always keep an open mind and follow directions. For $9.00 a gallon for the thinner, this was great.

[@diycarhome9151]

I done different methods of cleaning cats and passing emission tests. My last emission test was on a 1988 Dodge Omni. I did everything from changing oil, plugs, air filter, vacuum leaks, etc. I could not make a spec I think it was the parts per million of Nox. A work mate recommended getting the car drunk. I could of used 100% vodka, but opted to used 4 litre of methyl hydrate. Ran that with 91 Octane gas. The exhaust was so clean smelling, took it to the garage for a emission check and blew really clean. It passed. Fast forward today. Got a 2009 Chevrolet Aveo 1.6, getting a P0420 code. Cat problems. I cleaned the Cat. Out because flow thru the holes was still good.. Made a flange to block one end of the Cat. Put Cat. Vertical and filled it with Muriatic Acid..This ate the crud inside. Let it sit for 3 days. Then washed it out with hot water and liquid soap (Dawn) let it dry. That was the end of the P0420 code.

Great video, as always! Scotty recommended one gallon of lacquer thinner in half a tank of gas. You put a quart of thinner in 2/3 of a tank. If the tanks are roughly the same size (granted, a big assumption), then Scotty's solution was over five times as concentrated as yours. That may have made the difference.

[@OnTheOpenRoad]

Respectfully, this did in fact just work for me! My wife’s ‘08 Jeep Commander (152k miles) has had the check engine light on for nearly 3 years now. The Jeep Dealer quoted us between $2400 and $2800 to replace it. I said no, because the car’s performance didn’t seem injured, and that I would eventually do it myself (after market part about $400). That said, it’s no easy job, I’ve just never gotten around to it. Well, decided I was going to do the replacement. had seen your video previously but was very nervous about trying this. Well, after much online research, I decided to give it a shot before ordering parts. SO GLAD I DID!!! With a nervous tension, I poured a $13 can of Lacquer Thinner that I got in the paint section of Walmart, into the gas tank. Well, a can and a half actually (so, $26), as we had about 15 gallons of gas in the car, and the perceived ideal ratio is 1:10, lacquer to gas. Then we drove the car around for about 80 to 90 miles last night and tonight. Well, about 5 miles ago, BAM! Problem resolved. I ran the diagnostics again (I use the Bluetooth FIXD tool, although this one is cheap and I will eventually upgrade to something more functional), and the P0430 Catalyst engine error is now gone!!! Wow!!! Just WOW! I must admit I was scared about doing this, but...the science prevailed and I did it. So glad I did.

Eric, You are correct in if there is something wrong with the catalytic converter, such as the media comes lose, thinners are not going to fix it. Since this video is really old I'm sure you've resolved the issue with your converter but next time you test someone's recommendation, you should follow their advice. Scotty recommended 1 gallon per 1/2 tank or about 10%. You added 1 quarter of his recommended so it's no wonder it didn't work out for you. My check engine light came on about a week ago and codes indicated the converter was bad. I just did exactly what Scotty recommendeded, 1 gallon per 1/2 tank on a 2011 chevy equinox, drove it about 40 miles at highway speed. Check engine light went out. It does seem to work, if the catalytic converter is not damaged.

[@TheCrystaltrottier]

You have to use an entire gallon of lacquer thinner with 1/2 tank of gas like Scotty kilmer instructs. I have done this with 3 vehicles and it worked like a charm every time. The cats were also severely clogged in my vehicles. The cars would only drive for 10 minutes before they would lose all power. Living in CA I sure as hell wasnt paying for a replacement cat.

Eric: Have to agree with many others here. If you're gonna try the lacquer thinner test as Scotty suggested, then you should use the mixture he recommended - 1 gallon lacquer thinner to 9 gals gasoline. This is a 10% solution. Your test used 1 quart thinner to approx 7 gallons fuel (28 quarts). So your mixture was only about 3%, not 10% as Scotty recommended. Please try it again if you can. I'd be interested in your results. Thanks! Love your channel.

It works best if you add the lacquer thinner to 1/4 tank of fuel, drive 20-30 miles then fill up and drive as normal. Light usually goes out on it's own before you get back down to 1/4 tank. It also cleans the O2 sensors so they read more accurately. If the ceramic substrate starts breaking down, it will clog MECHANICALLY, NOT chemically and lacquer thinner won't work.

Good know it.

[@K7DFA]

To obtain the same ratio of fuel to laquer thinner, (1 : 9), with 3/4 tank of fuel you'd have to add 1.5 gallons of the laquer thinner to the fuel tank. As several others have already pointed out, you can't "debunk" or "prove" anything if you're not willing to completely follow the directions provided by the previous experimenter! 18 *.75=13.5 gallons (fuel in the tank), 13.5 / 9=1.5 gallons (additive needed), for complete duplication of the previous "experiment". Even if the experiment was completely duplicated, "Scotty" makes no guarantee that it will work every time . . . . so, you might still have to remove the "cat's", and use a different cleaning method, or even replace them to obtain the desired results! 🙂

I had a P0420 I couldn't get rid of, so I thought I'd try lacquer thinner - nothing to lose, right? 2001 Chevy Express 5.7 Vortec. I put one gallon of thinner in 1/4 tank, so approximately 10 gallons of gasoline. I drove it 100 miles, and I re-ran the test (using AutoTap Express). Bank 1 sensor 2 reading was now almost identical to bank 2 sensor 2, so I proceeded to the emissions test. It passed with no problem. I can see a couple of problems or oversights in this video. First, the proportion of thinner to gasoline is way too low as compared to what Kilmer recommended. Secondly, if you pay close attention to Kilmer's video, you're only trying to pick up that 1 or 2 percent of efficiency that drops you below the emissions testing threshold. Even Eric's readings seem to show at least that much gain. If you've got P0420 and you don't want to buy a cat, spending $20 on a gallon of lacquer thinner is not a bad gamble.

Years ago I had a van with a clogged converter. With nothing to lose, I pulled the pre converter O2 sensor and squeezed a pint of dawn dish soap in the hole. I then adapted a garden hose on the o2 outlet and ran the hose for five minutes until it ran clear. Lots of carbon came out. I put it back together and started it. I ran for years without any trouble.

My daughter's 2015 Honda Fit (88,800 mi.) had the CEL come on and it was throwing a P0420 code, so I added one gallon of lacquer thinner to ten gallons of gas and drove the car on the highway at 80mph for about three hours, and that CEL went off. It looks like many people are recommending a 1 to 5 ratio on LT to gas. I'm planning to do the same with my my 2011 Honda Odyssey now that I've deleted the VCM. (12/14/22)

Scotty says in his video he has been, successfully, using LT for 30 years. If you're going to do a test to myth bust something you need to do their test, not your version of it. I've seen the actual Myth Busters do the same thing only to show their own ignorance. If you go look at Scotty's video the first 10 top posts with scores of upvotes are people that did it and cleared their cat codes. This is one video that would have been better had he actually done it the way it was intended to be, now the majority of peeps that sees only this video are going to assume it "just doesn't work" as if everything is as black and white as it works or it doesn't. You don't buy 1 quart of oil to change your oil when it takes 4 quarts. You get 4 quarts. If it takes 1 gallon for a half a tank of gas and 150-200 miles of driving to work, if he wanted to "be safe" and use 1 quart he'd have to drive 800 miles to get a full gallon worth, and even then it might not work because the ratio is key.

[@MonzaRacer]

And I can tell you as a diagnostic tech and exhaust specialist I have made quite a bit of money from Mr. Kilmers little fantasy as I have seen more than my share of melted down converters from this idiotic trick. If its contaminated not much will fix that. That being said there is a chemical that WAS designed to help bring back converters that have carbon/oil consumption residue issues and possibly even antifreeze contamination. It is sold by Mr Gasket and is called Cataclean. It is marketed as a fuel system cleaner and catalytic converter "cleaner" and DOES work. The issues with lacquer thinner is there are several different "mixes" from the brands. The generic stuff Eric used is for cheap paints and varnishes and such NOT automotive paint which is considerably more sensitive to chemistry. I know from reading and such that a person found Cataclean, then tried the sniff test and may have even seen an MSDS sheet on it but got no specific concentrations of any chemicals involved. The theory of the lacquer thinner I have found came from back in the day of flat bed pellet converters and engines burning oil for what ever reason. Lacquer thinner made older engines run hotter on the exhaust mainly due to carbs not being designed to meter lacquer/gasoline mix AND newer gas has ethanol also. And the computers wont allow the exhaust to overheat as most OBD2 cars also monitor for EGR temp as many cars have plastic intakes/gaskets and high EGR temps may cause engine damage. You want to do it do so at your own risk because I have seen too many cars come in with melted down converters from the lacquer thinner trick and when a converter melts down, your talking at least $350+ to get a proper one. Yes Yes I know you can buy super cheap ones from Ebay, been there, done that and got P0420/P0430 codes and also had cars fail emissions when they go home. Heck some car can run as high as $1000 to replace converters parts alone as they have 4! Good luck if you try this , in my professional opinion as a 30+yr tech, hoax and I hope you dont trash your car.

[@freddyflintstoned913]

What ratio do you think you had. One quart is not exactly 128 ounces. It is 32 ounces. Not a good test. Invalid.

[@who_wantsit]

I just tried this, it worked! Using the correct thinner makes all the difference. BG products makes a product called 44K, main ingredient is High Flash Naptha. I found that Sherwin Williams has a thinner that has a huge amount of Naptha in it & they also sell pure High Flash Naptha. The stuff Eric has there in his hand has ZERO Naptha in it. HIgh Flash Naptha burns really hot and fast and clean. If the precious metals are not burned out of your cat, this should bring it back to life. No hesitation at takeoff, pulls giant hills like a champ now. Thank you Eric!

[@porpo-donut]

great answer. the naptha is the solvent "thinner" in lacquer thinner. Lacquer thinner with naptha dissolves these carbon clogs in a catalytic converter...it's the danger to the human handling the product. Please read the safety precautions as handling, like woodworkers went water based polymer because of the harmful effects of lacquer thinners. Just make sure you wear a 3M R95 or N/P100 mask rated to remove naptha (above N95 particulate respirator) and wear personal protective equipment in well ventilated area.

I have 06 Altima which kept pulling P0420 showing bad cat. I watched Scotty's video and decided with 230,000 and a replacement cost of $1300 to replace cat I would give it a try. I followed the EXACT directions of Scotty (unlike you did on this video) and I put one full gallon of thinner into 10 gallons of gas. (a little less than 3/4 tank) I had to do a Dallas to Houston drive so it worked out perfect. I ran out the whole tank on I-45 going 75-80 mph. I added some 93 octane (which I read from other posters could help) I reset code and drove another 100 in the city before checking it again. No pending codes and passed inspection with flying colors. Maybe a coincident ? Maybe but I would say for the time being I am a believer. P.S. Cataclean is a good product too but it does not work 100% of the time. Follow directions accurately if you want to do a real test.

[@petset77]

Thanks for the test. Your explanation toward the end of the video explaining different possible issues for a bad cat is something I hope everyone stayed around for. Pouring any solvent into a fuel system certainly won't "fix" a bad component. The idea is that it might clean the elements inside of a catalytic converter, thus get it to function more efficiently. You showed that adding a pretty dilute solution won't damage the vehicle, so that's more evidence to trying this. That it didn't clear your code suggests that perhaps the mixture wasn't optimal (it's certainly not 10:1, or even the 5:1 as some who have used two gallons to a half tank have done), or there is physical damage to the cats on this vehicle. The value in trying this is that whether it works or not, it's an attempt that costs less than $20 compared to new cats costing to over $3000 (in 2023, for CARB compliant OEM Subaru cats). No one who has tried this and shared video has destroyed an engine, on any make of vehicle. I suggest it's worth a try.

Started the car to finish up our trip home. To my surprise the check engine light was off. No need to reset anything the check engine light went off on its own.

But, this may be a special case. The head gasket blew and several gallons of coolant went thru the exhaust. A few months after the gasket was replaced the code appeared. The converter on that side (V6 engine) was covered with a white layer. The other converter looked fine. 230k miles, original converters. 3k miles since the cleaning. Downstream O2 sensors are giving a flat (expected) output. So, I can confirm that if the cause of the problem is coolant in the exhaust, soaking with dishwashing soap works.

You need to run it long enough if not it will rather end up clogging the converter by removing all the carbon in the engine and depositing on the converter. Another way I have found to work well is removing the top O2 sensor and using a pressure gun to feed the thinner. It’s fast and very effective. Doing that for 30seconds should be okay or you risk filling up your cylinders with thinner. Engine will eventually start even if it gets filled but don’t overdo it.

[@breasonable4343]

tricky! So forgive my ignorance, but you run the car parked at say 2500 rpm and feed the laquer thinner through the o2 port on the manifold? How much, how long?

[@everythingtrendingworldwide]

@@breasonable4343 car needs to be off to be able to do this cos when car is on exhaust gas will come out of the port with pressure. Feed the port with little amounts of thinner to avoid it climbing back in the cylinder.

@@breasonable4343 good thing about thinner is it’s inflammable like petrol so if some gets into the cylinder the engine can burn it off but getting too much in there can hydro lock the engine and it’s not good for your cylinder walls as it will corrode the protective coating.

Drove at highway speeds until the gas tank had a gallon left (Approximately 160 miles or so). Filled with high octane gas, which my car requires. The moment after the fill-up and starting the car back up, light came off. Much better vehicle performance as well. At about 108k miles. We'll see how long this lasts.

[@davidmack834]

I tried this, and it worked as far as my scanner was concerned, and the temps were lower through out the exhaust. Here is the difference, IMO, there is general purpose Lacquer thinner you get from Walmart, and there is the Lacquer thinner you get from the automotive paint shop. This thinner is MUCH stronger, and more expensive, than the cheap general use thinner from Walmart, or other stores. The thinner used in this video looked like the weak thinner sold for most oil base house paints, not the stronger automotive thinner. I watched Scotties video, and he was using the exact automotive paint thinner I use to clean my paint guns [again strong stuff]. I poured a gallon into my exhaust, and my wife, and I took a long trip. Now the engine did run differently with the automotive thinner in the tank, but nothing to be concerned about. After getting back home I noticed the rotten egg smell from the exhaust fumes was completely gone. Then I ran live data on my Innova scanner, and the numbers were significantly different, as well as the exhaust temps. The engine ran better after this, with no stalling/studdering, and had a bit more power. Also no problems with the fuel system, and I'm betting the thinner actually cleaned up the injectors [I've used it in the past to soak injectors with good luck, so that one was a given]. Point is, use automotive paint grade thinner [it will smell different]. This thinner don't have to be the most expensive stuff they sell, just ask for some lacquer thinner to clean your paint guns, they will know what you need. PS, the house oil based thinner WON'T clean an automotive body shop paint gun, but it will make a glob mess, and just about ruin it. Good luck.

I came all the way back to tell you guys what happened. I didn't wanna drive 100 miles so I divided everything by 10 and ended up putting just 1 pint in with 1/8 tank (about 2.5 gallons) I was gonna put 2 pints which would have been the correct proportions but the hardware store was closed and I had to go to work. its about a 10 mile drive. I poured it in, drove to work, felt some extra power, got those rpms up. then I went to the gas station by my work, revved it up for a while to try and burn it off, then I put some gas in the tank to dilute it so it wouldn't just be sitting. then I drove to work nearby and let it idle and revved some more to get it all out of the system. now when I turn the key, the car starts right up. before it had to wait about a second. I did this because after using seafoam in the intake I had power loss at high rpms. kind of like a preventive maintenance type of thing. my car runs quieter now. this shit works.. just do the math and put in the amount for the distance you want to drive.. I wasn't getting the cat code tho so if you have that maybe you do need to drive 100 miles. i might do it one more time in the future but for now im happy. i used klean strip brand lacquer thinner in my audi a6

[@davidturner2113]

Very interesting video. Maybe people should put the stuff into their gas tanks when the car is younger; to keep the converters clean. Like maybe once a year. That might keep them clean a longer time.

[@greasystrangler3703]

from what little I understand about the subject, cats get clogged mainly due to an engine burning oil. If the car is younger and not burning oil, then there is no point in doing this. However, if you keep an eye on your dip stick and notice that it is burning oil but the cat error codes haven't started yet then it may be a good idea to do it as a preventative as you say.

[@anthonyiocca5683]

I add a “gallon” of lacquer thinner to between 5-8 gallons of gasoline. Before oil changes is my rule of thumb , to keep the cats cleaner and clog free. I do it the smarter way. I put a 5 gallon can with fresh fuel in the trunk with the gallon of lacquer thinner. Then with a half tank or less I head to the interstate. At a rest stop or before entering the highway I pure that gallon of lacquer thinner into my gas tank with the engine at operating temperature. I drive with the overdrive “off” until the fuel is nearly depleted. I carry the 5 gallon can with me just in case I need it. I have done this a few times now, and I have not needed it. No sputtering, no hesitation with my engine, 4.6L Mustang 2007. All catalytic converters get dirty then they can get clogged. When they get clogged 2 things could happen; 1. The exhaust pressure could blow the clog out of the system. 2. The exhaust pressure blows the clog along with the internal catalyst materials out of the system. Causing a catastrophic failure.

I was curious too and conducted the test yesterday and even uploaded it, so far so good,I'll give an update though.

[@TomBTerrific]

Eric I for one am happy that you challenge Scotty's claims. I like Scotty's videos and yours. To me it keeps you both honest and we all benefit from that. I would bet Scotty welcomes your checking his claims. Most of us DKS about working on Cars and I for one rely on auto guys like you and Scotty to help me understand my automotive problems. Keep Keeping on...

[@mjpeter3964]

I agree. I've Googled "add solvent to gas tank", "lacquer thinner in gas tank", and others and it seems like only Scotty Kilmer and a bunch of Don't Knows are "successfully" using this method. I'm open to other experiments but this is the ONLY one I've found from a reputable mechanic. I don't have time to exchange one error code for another... Is this like prescrip meds? The pill cures your headache but gives you kidney failure instead??? If lacquer/ or Short Line Solvent cures one problem but causes another, it's just easier to replace the bad part, instead of trying to hide the symptoms.

Test not complete: Should be 1 gal lacquer thinner to 1/2 tank of gas.

Should be 0 gal. This car didn't start off with a code, just a supposition.

Try following instructions. Your results only prove that when you don't follow instructions, you can not expect positive results. Thank you for that reminder.

[@lowbux73]

A little more research into the type and proper proportions of lacquer thinner to gasoline should be in order here. Not all lacquer thinners are the same. They vary in formulation as much as gasoline does at different gas stations. To the best of my knowledge, the solvent Scotty used is PPG brand JT501 and its composition is different from the brand used in this test. Noted below are the compositions per their respective Safety Data Sheets. And if proportioned correctly I believe the JT501 would work better. But since I am in California, we aren't allowed to use real chemicals here and the California AQMD version of the same brand lacquer thinner you used is 95% acetone. And since acetone is what does most of the cleaning but is also what will eat your rubber seals in higher concentrations, I do not recommend anyone putting that stuff in their tank. The concentration is just too high. So locating something close to the JT501 formula is key. PPG JT501 Toluene 50-75% Methanol 20-30% Acetone 10-20% Ligroine 5-10% Klean Strip Toluene
