ETCG when you put the lacquer thinner in your fuel it is not a coincidence that you check engine light came on. The air/fuel threshold of the thinner is much higher than gas so the O2 sensor is getting a lean mixture count.
Also the lacquer thinner will tend to dry the cylinder walls (wash away the protective oil coat), but I’m sure I’m not telling you anything you don’t already know.

Moved you to the proper forum. 😉

Eric, you had a major hairstyle change in the middle of the video. Is your barber that far away? Thanks for the video, it was worth the try and made a great video. Disproving things is great information. I would be interested what caused the light. Also I have had bad luck with subbies of that vintage always having cat problems.
I’m surprised anyone haven’t suggested a blend of the two “methods” to clean the cat 🙂
Just remove the cat from the car, and then put it in a laquer thinner bath to clean it! :silly:
The best of both worlds…or the worst? :huh:
Well, for the “fun” of taking the cat out of the car, I’d say it’s the “worst”, but quite probably the full impact of the thinner on the cat’s dirt would clean it a lot better than soapy water.
Only thing that perplexes me is this: does lacquer thinner contain lead?
Because lead does indeed damage the cat… :whistle:Who knows?
Live long and prosper (and stay dirty!)

I knew this would get people talking. I think that’s a good thing. For those that have suggested soaking the cat in lacquer thinner, I don’t think this would be a good idea. It might clean the cat, but the residual cleaner left in the cat might present a fire hazard when you run the vehicle. The cat is designed to get very hot, if there’s still cleaner in there when you run the engine it might ignite and cause a problem. That’s only a theory though, one that I have no intention of trying.
With the price of cats being pretty cheap anymore, Walker makes 50 state legal cats that run under $300.00 I would just replace it and be done.
I still believe auto repair offers the best “bang for buck” of all the trades out there when it comes to paying someone else to do the work. My wife’s brother works installing windows and doors and I am amazed at what they charge. He told me normally they mark up parts 300-500% and charge $58.00 a square foot and a show up fee of $150.00.
Our shop has a contract with BG products. The salesmen told the shop that their 44K will clear a p0420 code as long as the cat is not melted or broken up…… If its true or not, as a technicians point of view I have to make money so i am going to weld a new cat in. Not sell you a 30 dollar can of snake oil and hope it clears your light. As a DIY buy a can of BG 44k and let me know if it works.
I really want to know if Scotty Kilmer can actually fix a car. or is he just a con on youtube.

I’ve had issues with 50 state cats. Sometimes the code comes back even with the new cat. Some vehicles have pretty tight tolerances when it comes to cat monitors, Hondas come to mind. It’s worth a try, but if it doesn’t work you’re out the cost of the aftermarket cat AND the one that will actually fix the code if you need the code gone. That would be a bad day indeed.
Very true Eric.
For a Toyota or Honda I push for OEM Cats made by the original supplier. Most Chevy,Chryslers and Fords seem to do really good with aftermarket cats.
Indeed, he is. I have messed up with the fuel system because of putting laccquer thinner into the system.
I am an amateur on Auto Repair. My car is 1999 Honda Accord 3.0 V6.
I have watched Eric video and read the comments. They argued that he did not put enough lacquer thinner (should be half tank and 1 gallon.) I did the same. I bought 1 gallon of lacquer thinner at Home Depot and suck it all into the fuel tank.
At first, I ran okay. However, my car started to have rough idle, loss of power, engline light blinking, engine code P0301->P0306 + P0300 and P01999. I tried to dilute those shit out of my car by trying to let the car run until nearly empty tank. Badly, the problem still persists.
I will try to do the fuel pressure test tomorrow. I believe I have might to replace either fuel pump (included the fuel filter) or some fuel injectors.
I will update the post later. Wish me luck. Hopefully someone can give me some advice.
Hi guys,
This is a quick update. It’s turned out that the lacquer thinner in my fuel tank damaged my fuel injectors.I have changed the fuel injectors and the misfires go away.
I check the data sheet here, acetone is made up 50% in this one.
http://www.kleanstrip.com/uploads/documents/KS_Lacquer_Thinner_MSDS.pdfI found this one (http://peswiki.com/index.php/Directory:Acetone_as_a_Fuel_Additive). It basically mentions some people experienced damaged fuel injectors (and fuel pump) too.
Hope it’d help someone
Isn’t it the check engine error code never return after the test drive. That means the lacquer thinner works. I use Cataclean last time I have problem with my Honda CRV because of valve clearance problem and after valve adjustment my CAT is dead that I can feel the backflow in acceleration. I use it in quarter tank of gas until empty because before the second time I follow the direction in the label of the product and it only work a little bit but I know it did work it just my cat is way dirty. Last month I tried lacquer thinner after watching Eric’s video with a pint in half tank and drove it to empty. Now I noticed my car breath better and have a better pickup which is almost like when it’s new when I first pickup the car in the dealership. I also remember using aviation gas in our shop service car when I’m aircraft mechanic, car never have any engine problem for using aviation gas which is 110 octane. It’s just quiet and fast, our shop car is ugly and rusted but everything under the hood is well maintained by a handful of aircraft mechanic back then. High octane should not be a problem unless you race the car for a long period of time or your cooling system cannot handle it. It’s just purely clean burn… lacquer thinner did work on my Honda CRV to clean the cat from after valve adjustment.
Raising this old thread, but something that was worth mentioning.
1st, I have not done this to any car, just being scouring the web for the good/bad/ugly on the topic of throwing lacquer thinners into the fuel tank.One perhaps critical thing seems to be missing and that is Lacquer Thinner is a generic term for a general purpose paint thinner and the actual composition varies wildly from manufacturer to manufacturer.
Since the video that got everyone talking comes from Scotty Kilmer, lets look at what he was peddling in his videos. He shows it up close in his “How to Get Your Car to Pass the Emissions Test” vid (3m31s), namely Shop-Line JT501.
Looking at the safety/data sheet it is made up of 30-60% toluene, 10-30% methanol, 7-13% acetone, 5-10% Ligroine (Petroleum ether). Notably toluene is pretty high (also used as a gasoline additive) and acetone is pretty low (“Solvent for fats, oils, waxes, resins, rubber, plastics, lacquers”).If we compare that to a “lacquer thinner” from Home Depot namely “Klean-Strip” it has less than 5% toluene, and 20- 30% acetone (basically double), also 25-30% methanol, and 20-30% other alkanes/cycloalkanes (unnamed/unclassified).
So what may (or may not) be working for Mr Kilmers cars/customers/victims may not work for you, especially if you are dumping just any old “lacquer thinner” in the fuel tank with lots of acetone in particular.

http://www.jasco-help.com/uploads/documents/Jasco_Lacquer_Thinner_CJLT70_GJLT70_QJLT70_MSDS.pdf
Has up to 50% acetone, up to 31% toulene, up to 35% methanol, up to 35% naptha (Petroleum Ether) +others.quite a few claimed success with Klean-Strip
and one guy that stuffed his fuel pump with 2 gallons of Klean-Strip
https://youtu.be/u2BeB7z9jIAThere are still others that are trying to get better gas mileage by dropping pure acetone into the gas tank. Considering acetone’s one quality is in dissolving rubber and plastics, I cannot see how that is a good idea especially in the long term.
if anything i would go with sea foam. IF you can, recommend using a rig where it get sucked in thru the system rather than just dumping in the gas tank… chrisfix did a video where it got sucked in with a lawn mower and it was easy to SEE the result (smoking). Rig as in getting a foot or so rubber hose and a funnel to insert the fluid, or perhaps, look of a sucking hopper ..not this entire thing just the main piece for holding the fluid until it gets sucked in.
chrisfix video
good luck
Man i ran seafoam through the vacuum lines of my old car one time and had to replace almost every vacuum seal that was gasket or rubber. Granted many were probably only being held together by the carbon that got burned off, and it was better in the long run, but still I was finding and fixing vacuum leaks cropping up for months.
So yes, it will reveal problems. Just be prepared to spend the money to, find, diagnose and fix those problems it has now helpfully revealed for you!
