You can trust good old Scotty Kilmer! I tried this on my 1999 Ford Ranger. Check engine light was on. She was losing power. I had the ignition coils replaced. Still losing power. I poured the lacquer thinner into a 1/2 tank of gas. It broke free at around 120 miles highway driving. It was like a horse breaking into a gallop from a trot! Believe me it works! 👍👍👍👍
Was your car able to exert more power after it cleaned up? My car struggles from crazy hesitation and I’m pretty sure it’s due to a clogged cat converter
My prius 2006 has check engine light on but the smog star station told me to replace spark plugs and catalytic converter, but the catalytic converter is way too expensive. Does catalytic cleaner really works on any car?
Sometimes I think Scotty must be full of it but I tried lacquer cleaner a few years ago in a F-150 and it gave great results. A month before the required smog test the check engine light came on. It seemed like a good time to try the lacquer cleaner. In short, it worked. The light went out, the truck passed with flying colors, and it's run perfectly and passed every smog inspection for the past 6 years or so. It's anecdotal but I'm convinced it did some good. Still the original converter and sensor after 120k miles. Scotty called this right.
There's a reason there are 4+ million views for this on Scotty Kilmer's video. I tried this last night on my '99 VW GTI Vr6. One gallon thinner to just over half a tank of gas (about 8-9 gallons). 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. I do know it cleaned the crap out of it.
@@andymedina323 It worked but light came back eventually. In this last round I used Seafoam when the tank was full. Once it got to a quarter tank, I added Cataclean. I ran it near empty and refilled. Haven't seen the check engine light in at least 6,000 miles and it's running very smooth. I did the lacquer thinner two or three times before this last effort, so I think it maybe just needed a lot of cleaning. The car is 24 years old, so.
Lots of people commenting have difficulty paying attention. Scotty said this method works for a clogged cat and it’s worth trying before paying a lot of money for a new one. Eric the car guy said his cat was NOT clogged. There was no reason for Eric to run the lacquer thinner through the cat. The whole point of this method is to clean out a clogged cat and to avoid having to remove the cat from the car. If you do want to remove the cat THEN Scotty said use dish soap in a bucket and let the cat soak overnight to clean a clogged catalytic converter. “Clogged catalytic converter”.
Use a bottle of Dawn and a bottle of Fabuloso, in a plastic tote big enough to submerge the whole cat then take the cat to a car wash and blast water from the back through the front until no suds, dry it and put it back together
below efficiency means clogged, just not fully clogged, eric meant, not clogged as in literally stifling the motor due to being so clogged would shut engine off after a few seconds
@@iceman125971 eric did not follow scotty's directions. scotty said a GALLON, eric used only a quart. hopefully eric made an honest mistake, but a lot of these mechanics on youtube hate scotty for no good reason except that he knows more than they do. not saying this is the case with eric, but only he knows for sure.
Thinner worked for me twice on a 1997 chevy silverado 5.7. Third time truck had bank one and bank two not reaching efficiency. Thinner worked on bank one but not bank two. I took truck to smog after canceling check engine light. I had to drive truck until monitors reset and took truck in before light came back. It passed, although the hydro carbons were a little high. Truck has 308000 miles. Good for another two years.
I recently tried Scotty's Recomendation . On my 1999 Toyota Camry 2.2 (4 cyl ) 235 K miles on it, runs good 🤷🏽♂️ With a PO 0420 code. One gallon Lac thinner to Half tank of gas , drove it 155 miles . Light stayed on . I cleared check engine 420 code with scanner . Drove it and Check engine 420 Code Pops up with in a mile . No Luck FYI just passing info on . I've also used Caticlean No Luck, And other Pass Smog additives No Luck. Just replaced catalytic Converter finally $$$ Smog check to be performed tomorrow . Will update . Hope this Sheds some light on any Questions . Good Luck All ✌️
I looked this up and saw the Scotty video but decided to use the Dura -Lube Cat cleaner…..Input 1/2 bottle to 1/2 tank of gas and drove 20 miles to run an errand. Stopped at the store, came back to leave and the light was off……it worked!!!
My mix was 1gas gallon to 1 lacquer gallon. And yes it worked. All systems go! Just drove normally until gas light came on then filled back up. Great solution. Light went off sometime next day I didn’t notice happy it just ran a lot better wifey told me.
Lacquer thinner worked very well on my 2006 xterra. Love how you always refer to Scotty as the old guy as if he too old to know anything. Truth is he knows more about mechanics than you ever will.
Interesting that you leap to presumption that calling someone "old" translates to someone being "clueless." There was a time, back in the day, when someone "old" (elderly, senior, etc.) was venerated for being considered having experienced life and learned ALOT from it. In the military, there is a custom of calling the unit commander "The Old Man" as a sign of respect...in "da hood" calling someone "OG" is intended to reflect giving props to someone who's learned how to cope with life sufficient to have attained an advanced age. Can't help but feel...this vlogger may have been expressing disrespect of Scotty Kilmer by describing him as "old" - then, again, he may not have meant it as disrespectful, at all. As for you...you're not the first person I've encountered who strongly insinuates that "old" must automatically translate as something not altogether positive. Interesting.
Have I missed something?? Can someone tell me where the up to date video is. I do believe that big rig drivers to put lacquer thinner into their fuel tanks but no one does report if it does do damage in the long run
Had a p0420 on a car with 230k....tried it but really didn't work....i ended up putting in new plugs, pcv hose, new 02 sensors, new exhaust manifold, new fuel injectors and new cat. No more p0420. Now consistently getting 5 MPG better overall too!
when I went catless my average mpg improved by about 4, could be cause its loud and I drive it 30 miles through towns and shit so I'm lighter on the throttle, could just be cause its catless
In principle catalytic converters should never go bad. From a pure chemistry point of view the definition of a catalyst is something that promotes or speeds up a chemical reaction without itself being consumed. So the metals in the catalytic converter under normal operation should theoretically last forever. So really there are just two ways cats go bad, one is from actual physical damage. From my understanding this usually occurs when someone drives with a misfire which basically dumps raw fuel into the cat causing it to overheat and melt internally. No way to fix this. The second way cats go "bad" is by getting gunked up with carbon by doing too much low RPM city driving. The cat just doesn't get up to proper operating temp often enough to burn off the carbon build up. The solution to that is to take a long highway drive in low gear keeping the RPMs above 3500 for say 15 - 30 minutes to burn off the carbon build up. I've seen that work many times. I guess if the Lacquer thinner thing works, it would be because it effectively causes the engine to run extremely rich causing some of the fuel / lacquer to go unburned in the cylinder and makes it's way to the cat where it ignites and gets burned and heats up the cat enough to burn off the carbon. I'd worry however that you could overheat the cat like that and physically damage it permanently.
That didn’t work with me after driving my v6 Infiniti with one bad coil number 5 in bank 1 for 150mils :( i think i will soak the converter in thinner for one day. Lets see if that gonna clean it tho
Is this thinner considered a fuel additive? I heard additives are not good for long term health of your engine...Because if not...I plan to pour this one gallon of thinner at least once a month on my 2017 Hyundai ioniq due to excessive driving for Uber Lyft a lot....I'm currently at 240K mileage and my engine light code of P420 disappeared after I did this...so far almost 200 miles running and engine light still out
Try a Gallon Of Lacquer thinner, a gallon of Acetone, and a gallon of Turpentine . add to a quarter tank of gas and drive 50 miles, thats what I did. No more lite , no more car , No more me !
I don't know if this works although my dad put diesel in gasoline engine believe works well clean put in before week before oil change made a difference
My daughter put diesel in my Matrix, I used anti-fowlers for 5 years but finally could not fool the o2 sensor, One gallon in a half a tank and drove like I was 20, code Cleared and hasn't retuned.
Changed all 4 of my sensors on my Lexus. Kept getting the code so I used this method. Works everytime. I dont get the code for another year or so. I also dump it in the tank when i have less than a 1/4 of gas left
@@mycadi94 I have a 2002 ES300 205k miles. I'm going to do the lacquer thinner and drive tonight. I have the P0430 bank 2 code. It came on and I immediately used CataClean and the code came back. I took it out for a drive last night to burn gas down to a half a tank and the CEL went out. So right now no check engine light but I am still going to try this lacquer drive. I have a scheduled appointment with my mechanic in a couple days about the P0430 code. While on the phone with him he immediately went to replace the CAT $1500 to $2000. We settled at they would put it on the machine and run a complete diagnostics test as a misfire can throw the P0430 code. I figure WTF might as well give this a shot right?
@@lightworker303 It came back. It still goes on and off. I’m not going to replace the CAT. My son is driving it. I don’t want to spend that much. As old as the car is and with that many miles it isn’t worth it.
You have to drive it right away at 120 until most of the fuel is gone, don't let it sit in the tank for days ! I did it to my vehicle, it doesn't hurt anything, Scotty's been doing it for decades.
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)
@@WNatureTV Yes, it did come back on. It turns out the fuel injectors were bad and this is a known issue with the 15 and 16 model years. We took her Fit to a Honda dealer and they installed new fuel injectors at no charge. That saved my daughter $2000 as quoted by an independent shop.
Man you’re helping Scotty Kilmer get views…..maybe a colab is next? The cats likely bad because it was overheated (misfire over fuel condition causes combustion in the cat) and the catalyst separated from the case, allowing untreated exhaust gases by.
Thumbs up, if only for whispering "That's a joke" after saying it's no big deal to get lacquer thinner on your paint. (in all actuality, a couple drops splash on auto paint isn't a deal, because it'll evaporate before softening the finish....you wouldn't want to soak a painted part in LT, or scrub the surface if it's wet with it). Anyway, I've watched a number of these vids, so want as many opinions with as many different engines as possible. Wife's Subaru Crosstrek throws the P0420 and I'm likely going to try this trick. On to your follow-up video. Thanks.
Did this to a 08 honda civic hybrid. Car wont run now 😅 Debating if i should take apart the gas pump and remove all the gas. (Full tank) regret doing this
Potentially unrelated. Could be bad timing, or you could have bought a laquer thinner not good for cars. Not all laquer thinners are made from the same chemicals
However, most car manufacturers do not recommend using lacquer thinner because it can damage any plastic or rubber parts, which includes valve covers, gaskets, and seals. Damage to these parts can cost more to replace than the catalytic converter depending on the model of the car.
@@Carlosruben503 i fixed my engine codes by fitting an extension on the front catalytic converter sensor. Seems my cat was ok. Its been a year now with no engine codes. My engine was replaced before hand due to excessive oil consumption. I just assumed the cat was full of oil, but seems it was ok. The o2 extension was from ebay and only cost $20 Australian.
I'm 71 and worked in a body shop when I was in my early 20s. Sometimes I rode my Honda 90 on the dirt backroads to and from work. I just made it to work one morning low on gas and didn't have access to gasoline. We had a 55-gallon drum of lacquer thinner with a hand pump. I put a little in the tank to get to a gas station and the bike didn't seem to run any differently than it did on gasoline. You mentioned that lacquer thinner will not harm automotive paint. GM used to paint their cars with acrylic lacquer. Lacquer thinner will melt those early automotive finishes. One time my painter's helper laid a lacquer thinner-soaked rag on a customer's car roof that was in for repair. I had to repaint the customer's roof.
The whole idea is to have this aggessive concoction ( 1 part thinner to 9-10 parts gasoline) in your tank for as short a period as possible......drive the car immediately at highway speeds to get the stuff to do it's job a ....but .... also to get it OUT ( drive the 150 niles or so to get the half-tank level at the start, down to nearly empty, and then refill with gas), and not leave it there a long time where it can harm stuff like injector seals. Why not follow the suggestions AS GIVEN ????
At the coal mine we have them so u can unbolt them easily and we was them out pretty frequently pin sole and degreaser works well but they are on a 8.3 liter Cummins
It will burn HOTTER than straight gasoline. / it will have different chemicals in the exhaust gasses that will react with the cat or with the carbon deposits...
Wouldn’t Thinners eat away at any rubber in the fuel system iv seen video of people washing them out with thinners but off of the car in a bucket preferably chemical resistant bucket leaving it to soak in thinners and then pressure washing the cells out probably best pressure washing from clean side to dirty side so that you don’t force any of the cray further in just a thought
@@NaptownTuner you gotta look at his older stuff. He helped me find a short in my old Camaro with one of his videos. He helped me to something else a few years ago too, I just can't recall what. He's somewhat...fairly... entertaining. I like the guy, I feel like he's likely a good guy, probably honest in real life...but you never know. HOWEVER...the clickbait $#!+ has really turned me off on his videos
One thing Scotty did in the video was to run the engine at a moderate speed for 30 minutes in Park. This would get the cat hotter than normal, and might burn off impurities.
Many automotive fuel injector cleaners use Stoddard solvent. I know Chevron with Techron uses Stoddard which smells exactly like paint thinner/mineral spirits.
What is a Stoddard solvent? Stoddard solvent is a mixture of numerous hydrocarbons derived by refining crude oil. It is a petroleum distillate with a boiling range of 154-202°C and a flashpoint of 38-60°C. Stoddard solvent is commonly referred to as dry cleaning safety solvent, naphtha safety solvent, petroleum solvent, PD-680, varnoline, and spotting naphtha. It also goes by the registered trade names Texsolve S and Varsol 1. --- I believe I read that liquid moly cat cleaner has a significant amount of naphtha...
That’s the best advice I have ever heard, Just ignore your check engine light! It’s not like you can burn a valve with a clogged converter or anything!
I think a better idea might be to open the o2 sensor before the cat and spray some carb cleaner or pour the thinner inside the opening and let it sit for about 15-20mins and then replace o2 sensor (clean it while you have it out) and then run the car for 20-30mins at 2-3k rpms. This would be more efficient.
I believe the combustion sequence and fumes left over from the lacquer thinner will create a cleaning gas agent. With high way speed and temperatures reaching 1200F. Those are reactions needed for it to work.

You have to drive it right away at 120 until most of the fuel is gone, don't let it sit in the tank for days ! I did it to my vehicle, it doesn't hurt anything, Scotty's been doing it for decades.
2007 Honda Civic EX with over 250K lacquer thinner did the job!
What if you remove the oxygen sensor and pour a little into the pipe so it will loosen the carbon up
I was wondering the same thing. Thought of spraying a cleaner in there or something..?
This is the answer I’m looking for.
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)
Did you daughters CEL come back on? I have the same car and the same CEL code popped up. Was hoping this would solve my issue
@@WNatureTV Yes, it did come back on. It turns out the fuel injectors were bad and this is a known issue with the 15 and 16 model years. We took her Fit to a Honda dealer and they installed new fuel injectors at no charge. That saved my daughter $2000 as quoted by an independent shop.
yeah, 3 hour drive?????? I can't even do that!
@@joesmith9216 Have your mom do it.
@@mjhammer8121 yeah smart ass, I am not driving 3 hours to clean the cats out.
Yesss!!!! Scotty Kilmer and the nap in one video!!
Make sure you don’t have an upstream exhaust leak, even a pinhole will p0420 you!
Man you’re helping Scotty Kilmer get views…..maybe a colab is next?
The cats likely bad because it was overheated (misfire over fuel condition causes combustion in the cat) and the catalyst separated from the case, allowing untreated exhaust gases by.
Where's part 2??
After cleaner is through and light is still on disconnect battery terminals and reconnect
Who sells that scooter?
He does, made out of junked out Audi hatchbacks
What’s with the home tint job, u gotta clean in up or remove it
tint in general is classless
What we got here on video is a fair dinkum hillbilly attempting to pass himself off as a redneck.
I started doing this on the regular and it not only cleaned my cat but everything else as well. Engine clean as a whistle.
Thumbs up, if only for whispering "That's a joke" after saying it's no big deal to get lacquer thinner on your paint. (in all actuality, a couple drops splash on auto paint isn't a deal, because it'll evaporate before softening the finish....you wouldn't want to soak a painted part in LT, or scrub the surface if it's wet with it). Anyway, I've watched a number of these vids, so want as many opinions with as many different engines as possible. Wife's Subaru Crosstrek throws the P0420 and I'm likely going to try this trick. On to your follow-up video. Thanks.
I believe Eric the car guy did the same thing on an old subaru. I dont think it worked for him.
I was just about to type this but, came to check the comment section first..
He only used 1 Quart to half a Gas tank.. when Scotty specifically said 1 gallon of thinner to half a gas tank.
Did this to a 08 honda civic hybrid. Car wont run now 😅
Debating if i should take apart the gas pump and remove all the gas. (Full tank) regret doing this
Potentially unrelated. Could be bad timing, or you could have bought a laquer thinner not good for cars. Not all laquer thinners are made from the same chemicals
Spot on with the Scotty impression lol
Hey Naptown. Great stuff. I have a 2013 A4 in Chicago if you ever get to Illinois, would definitely like your help on a couple things.
I didn't know epic meal time worked on cars.
I automatically lost trust just based off the glasses
😂
Maybe if you remove the catalytic and wash it using the thinner it could clean it 🤷🏻♂️
I think it will work
However, most car manufacturers do not recommend using lacquer thinner because it can damage any plastic or rubber parts, which includes valve covers, gaskets, and seals. Damage to these parts can cost more to replace than the catalytic converter depending on the model of the car.
Everyone with an a4 wants this to work so bad. Me the most, got my fingers crossed
@@Carlosruben503 i fixed my engine codes by fitting an extension on the front catalytic converter sensor. Seems my cat was ok. Its been a year now with no engine codes. My engine was replaced before hand due to excessive oil consumption. I just assumed the cat was full of oil, but seems it was ok. The o2 extension was from ebay and only cost $20 Australian.
@@gasnxt6805 So... $5 yankee fiat?
Did the same with a 98 Chevy K1500. And it worked well.
Why weren't your "eggs" red on the IM monitor?
I'm 71 and worked in a body shop when I was in my early 20s. Sometimes I rode my Honda 90 on the dirt backroads to and from work. I just made it to work one morning low on gas and didn't have access to gasoline. We had a 55-gallon drum of lacquer thinner with a hand pump. I put a little in the tank to get to a gas station and the bike didn't seem to run any differently than it did on gasoline. You mentioned that lacquer thinner will not harm automotive paint. GM used to paint their cars with acrylic lacquer. Lacquer thinner will melt those early automotive finishes. One time my painter's helper laid a lacquer thinner-soaked rag on a customer's car roof that was in for repair. I had to repaint the customer's roof.
he also said just kidding!
Millennial sarcasm passed over boomer's head.
The whole idea is to have this aggessive concoction ( 1 part thinner to 9-10 parts gasoline) in your tank for as short a period as possible......drive the car immediately at highway speeds to get the stuff to do it's job a ....but .... also to get it OUT ( drive the 150 niles or so to get the half-tank level at the start, down to nearly empty, and then refill with gas), and not leave it there a long time where it can harm stuff like injector seals. Why not follow the suggestions AS GIVEN ????
The competency crises is rich today.
i played this on 2.o speed and this was even more entertaining. thanks
If you are willing to test it, I’ll come back for updates! Doesn’t seem like it should work, but I hope it does!
Same here, I showed my dad Scottys video years ago when I was having the same code, but to unsure about actually trying it.
@@danabigham3686 i did it on my VW 2.0 non turbo with p0420 and runned a gallon of lacquer every 10 gallons and did work and runned better.
It would be some work, but take off the converter and wash it out with the thinner. Is this feasible or worth trying 🤔?
In my option no because 9 times out of ten those bolts are so heat warped that you have to cut the CAT off.
At the coal mine we have them so u can unbolt them easily and we was them out pretty frequently pin sole and degreaser works well but they are on a 8.3 liter Cummins
It works on 3 of my vehicles
"if you get some of this lacquer thinner on your paint, it's no big deal..." bro, not everyone sees your sarcasm, hahahaha
i guess the water evaporates & the hydrocarbons/solvents stick to the catalytic converter?
What was the point of this video if he wasn’t going to show if it worked?
It will burn HOTTER than straight gasoline. / it will have different chemicals in the exhaust gasses that will react with the cat or with the carbon deposits...
LMFAO this is great
Wouldn’t Thinners eat away at any rubber in the fuel system iv seen video of people washing them out with thinners but off of the car in a bucket preferably chemical resistant bucket leaving it to soak in thinners and then pressure washing the cells out probably best pressure washing from clean side to dirty side so that you don’t force any of the cray further in just a thought
What do you think is in your gasoline? It's nothing BUT solvents mixed together.
Scotty is the KING OF CLICKBAIT. I cant watch him anymore
I don’t think I’ve ever seen him wrench on a car, just tells stories
@@NaptownTuner as another 50 year plus auto tech i find most of his "guidance" opionated bullshit. although sometimes comedic.
@@NaptownTuner you gotta look at his older stuff. He helped me find a short in my old Camaro with one of his videos. He helped me to something else a few years ago too, I just can't recall what.
He's somewhat...fairly... entertaining. I like the guy, I feel like he's likely a good guy, probably honest in real life...but you never know.
HOWEVER...the clickbait $#!+ has really turned me off on his videos
@@NaptownTuner I am guessing this hack didn't work for your innie or your AUDI ? What were the results?
@@NaptownTuner never seen him promise a part 2 to a video either.
One thing Scotty did in the video was to run the engine at a moderate speed for 30 minutes in Park. This would get the cat hotter than normal, and might burn off impurities.
...moderate speeds in park..?!
@@alexb2471 Your engine doesn't run in park? Mine does.
@@alexb2471 He meant 3500 RPM while in park
At (engine) idle speed the cat will cool off. Anything above 1000 or so rpm and they should heat up a few hundred degrees really quick.
Many automotive fuel injector cleaners use Stoddard solvent. I know Chevron with Techron uses Stoddard which smells exactly like paint thinner/mineral spirits.
What is a Stoddard solvent?
Stoddard solvent is a mixture of numerous hydrocarbons derived by refining crude oil. It is a petroleum distillate with a boiling range of 154-202°C and a flashpoint of 38-60°C.
Stoddard solvent is commonly referred to as dry cleaning safety solvent, naphtha safety solvent, petroleum solvent, PD-680, varnoline, and spotting naphtha. It also goes by the registered trade names Texsolve S and Varsol 1.
--- I believe I read that liquid moly cat cleaner has a significant amount of naphtha...
O2 spacer instead? Anyway, no inspection in Indiana so I ignore my intermittent P0420.
That’s the best advice I have ever heard, Just ignore your check engine light! It’s not like you can burn a valve with a clogged converter or anything!
@@NeverEnoughPyro40 P0420 is catalyst efficiency below threshold. It doesn't mean it's clogged.
@@n9wox it means it isn't functioning as intended. There is a handful of reasons that could be including being clogged.
I think a better idea might be to open the o2 sensor before the cat and spray some carb cleaner or pour the thinner inside the opening and let it sit for about 15-20mins and then replace o2 sensor (clean it while you have it out) and then run the car for 20-30mins at 2-3k rpms. This would be more efficient.
I say do what you said and then do what Scotty said. Just to double down on it and make sure it's clean and ready for future inspections.
I believe the combustion sequence and fumes left over from the lacquer thinner will create a cleaning gas agent. With high way speed and temperatures reaching 1200F. Those are reactions needed for it to work.
No update? I'm assuming the worst possible outcome then. Sorry
The old dude that loves his Celica! Haha . Scotty has 6m subs.
Actually,I used two gallons in full tank.Same basic thing.
It worked in my Tahoe
