Yes, you may want to see my more recent videos where I talk about Project Farm testing AT-205. It's still the best out of all the stop leak products. I hope you're a subscriber Jona and make those cars last baby!
Today put in a bottle of the new stuff in my 1998 Subaru with 235,000 miles for the weepy rear main seal. Doesn't leak enough to need to add oil between 3,000 mile changes but leaks on the exhaust and gets stinky. Never tried this so will see what happens? Update it's a couple of weeks later and it seems to be working. Yay
Been using it for years with no complaints from me. I just put a bottle in my trans and split a bottle between the rear diff and the power steering...all 3 stopped leaking within 2 days.
Nice work... yes, it's still the best (even thought it may not be as good as it was before the reformulation). I hope you're a subscriber and make those cars last baby!
Even with the newer non-smell updated formula, it would be good for a "test Update" on it's ability to stop leaks in cars & trucks oil leaks. I used this newer formula on our '15 X5 in the rear differential about 4-5 months ago. The rear pinion seal started to leak after I did a R&R on the diff fluid at approx 86,000 miles. (I don't understand why this leak started after the change of fluid. I used a good grade "Redline" GL5 fluid that Redline said would work) Anyway, I put in (1) ounce of AT205, topped off the fluid level, and cleaned all the leaked gear oil off the diff with brake cleaner, and the leak stopped withing a couple days. It's my understanding that that this AT205 just has an additive that "softens & swells" old seals. Maybe it's been modified a little to meet EPA requirements, but it still has the Diethylene glycol monoethyl ether greater than >90%, as shown on their MSDS sheet dated 24-May-2021. Thanks for your video.
Semper Fi! Glad to hear it worked for you. There have been a lot of guys telling me it works. But I've just had a significant number of subs tell me it didn't work at all (which is different than in years past). AT-205 is a polymer that swells and conditions seals. And for me and others it's been a major way to keep vehicles on the road... a key weapon in my arsenal to keep my cars looking and running great. BTW I've had lots of oil leaks after going with high quality synthetic oils in my engines, trans, diffs, etc. My dad years ago (former rep who sold engine rebuilding equipment) "Synthetic oil is awesome but it goes everywhere... some places you don't want it to go." So I've done exactly what you've done over the years. And the historic "nail polish smelling" version of AT-205 never, ever failed me. Thanks for watching. I hope you're a subscriber and make those cars last baby!
Good to hear xSailor ... a lot of my subs have complained that it just isn't as good as it used to be, even though I believe it is still the best stop leak product on the market. Hey I hope you're a subscriber and make those cars last baby!
Man I thought we lost you Switz. Glad you're still creating content. I would call the Manufacturer and ask them what changed with formulation and advise them that it is not working like the previous formulation. Makes you wonder why they changed it?
Hey Josh happy new year! Yeah, just busy with life and work. I have tried to contact the people who make this stuff but so far I have not had any success. Plus, if they reformulated it they will probably not admit to doing so. Overall it's pretty disappointing since AT-205 was a major weapon in making cars last 25+ years. I hope you have a great 2023 bud!
Dang. Now that I think about it, the bottle I got a few years back doesn't have a pungent smell to it either. That was the first and only bottle of AT-205 I've purchased (because I haven't even used the entire bottle yet). Glad you made this video. I'll keep the info you shared in mind when using the product. It's one thing if they reformulated it to eliminate the smell due to customer complaints, but if it doesn't work as well either, that worries me.
I like your chances if the oil leak is minor. Sometimes the oil leaks are big enough that you just need to change the gasket or seal. Best of luck, and thanks for watching. I hope you're a subscriber and make those vehicles last!
Will be disappointed if it is not as good. I did just put a bottle of the new stuff in my 1999 Honda Accord. Great car with 318000 miles but I found the pcv valve was stuck (my bad. Should have replaced about three times) and I think that started rear seal leak. I was losing about 1/2 cup of oil per day. Aft a 30 minute drive, i see about 15 drops. Much inproved! Will see after the recommended 5 hours. So far, it seems to work still.
Good hearing Bill. I think it still works better than anything else. It's just that I never saw any complaints (or hardly any) before what appears to be the reformulation. Thanks for watching!
@@veedamachine1 What I do is add half the bottle (4 ounces) to my next oil change. So I pour it in with the new oil. I then run it for the entire 7,500 or 10,000 oil change interval. Thanks for watching!
The bottle i put in last month with VR1 20w50 slowed the rear main seal leak to about half the amount but did not stop it like all the old reviews i read.
Yep. I've gotten a lot of that Charles. It's actually quite upsetting, and makes me want to create my own product called "Switz-206" ... a polymer based additive that has the strong nail polish smell and works like the old AT-205! Thanks for watching. I hope you're a subscriber and make those cars last baby!
So now AT 205 Reseal is charging double the price and it doesn't work as well. Well, i guess they shot themselves in the foot because bad news travels fast.
Hi, I have a bold idea. If tolerance is simply the weakening of the drug effect, can we double the dosage to achieve the previous effect? (It's just a casual idea; please do not attempt without proper consultation...)
It's still the best stop leak product on the market. But it doesn't work as well as it did. I have an upcoming video in which I will explain why they changed the formula. Thanks for watching!
I used this in my power steering pump and my power steering leak stopped about 98%, I only used about an once if that, I also spray my bushing with it...
I don't know Eddie, although if I had an old diesel and was looking at having to replace a valve cover gasket, main seal, oil pan gasket, or something else like that, I think I'd try 4 to 6 ounces of AT-205 on my next oil change and see if that works. Thanks for watching. I hope you're a subscriber and make those cars last baby!
The smell you describe sounds like methanol. See if the old bottle list it as an ingredient, perhaps they deleted it. That's the first thing you discard when making whiskey but it indeed does smell similar to nail polish remover.
Switz have you compared it to Lubegaurds Seal Fixx? I saw someone mention it here and saw Scotty K use Seal Fixx when AT 205 when off the market before reformulating. Thoughts on seal fixx as a better alternative? Thanks!
I have not tried the Seal Fixx, but I just might given the complaints about AT-205 post reformulation. Thanks for the idea! I hope you're a subscriber and make those cars last baby!
AT-205 is still the best... Project Farm has done more testing, and even though I don't think AT-205 is as good as it used to be, it's still 70% of what it was... and it's still the #1 stop leak product on the market. Thanks for watching Big Dog, I hope you're a subscriber and make those cars last!
Nice work Alex... yes a Silverado with 150K miles on it is a perfect candidate for AT-205. Now generally I only suggest AT-205 for older vehicles with minor oil leaks, not severe/serious oil leaks. In that instance I recommend replacing the gasket or other part that has caused the leak. So when you say 'serious' I'm curious where it was leaking from. Thanks, Tom the Switz
@@TheSwitzAutomotive - Chevy GMC pickup truck 4.8 motors are susceptible to leaks from a plate above the oil pan and just above the starter…the gasket fails…in order to repair/replace the gasket - the transmission needs to be dropped…I got an estimate $2500…I tried AT 205…drove it 35 miles out of town and 35 miles back - bam leak is sealed…I’m elated…
I added AT-205 to my 76 VW Bus camper. I''ve had it at 3 top classic car mechanics and they all say it's in great condition accept for the slight oil leak. Well, It's defiantly leaking a quarter size drip a day. So I put in the 205. 5 hundred miles later it's still leaking. Can I ADD more 205?. Will it be bad for the engine to add more ?. No one says that it's a major issue but the Bus still leaks with the 205. What should I do now?. Is another bottle going to hurt the engine. ? Reply
I bought the 4 pack off of Amazon about a year and half ago and dropped the 1 bottle in 1st time with no luck (I don't believe I recall the nail polish smell). Fast forward almost a year later (i don't drive much these days) poured the recommended 1 and 1/4 bottle on a fresh oil change on my now 11 year old f10 BMW and drove just over 10 hours next day from Toronto to Ottawa and in between and back I can't explain this but on longer drives when I've reached operating temperature, there are ZERO leaks. I've driven short 5 to10 minute drives where I've been disappointed to see almost golf ball-sized leaks. I have a slight weeping at the rear main seal but the issue is with the oil pan gasket.
That "nail polish remover" smell is "usually" acetone.. Acetone is not good for rubber and can actually "eat through" the material.. So, maybe it was effective in making the seals softer and expand more, but long term it may be weakening the rubber..
I researched it and it's not acetone... it's another chemical, which I don't presently recall. One of my subs explained the chemical is bad for the environment but good at swelling rubber gaskets and o-rings... thus the change. All I know is AT-205 is only about 70% as good as it used to be, but it is still the best on the market. Thanks for watching. I hope you're a subscriber Phil and make those cars last baby!
@@TheSwitzAutomotive Thanks for the explanation.. I also looked further and the "recipe" for AT-205 in 2018 was just 1 chemical.. diethylene glycol monoethyl ether.. all glycol ethers are classed as hazardous. it can cause severe health symptoms, up to and including death.. Even skin contact and breathing the fumes can cause issues. So, I can see why it was changed.. You might want to dispose of your old bottle at the local fire dept..
The old stuff is sometimes better. My parents have a couch that has cushions that are in good condition even after 40 years. The only bad thing is that in a fire, it is worse than napalm.

Believe me I wish I'd purchased 1000 bottles of AT-205 in 2015-2017. I could then sell them to my subscribers as needed to keep their cars on the road. All that said, the new formulation appears to work, just not as well. I'm doing some testing with it now. Thanks for watching.
@@TheSwitzAutomotive that be great man do you know if this sealer work in valve cover gaskets also? I have a 1995 4runner n it leaks from the valve covers
@@TheSwitzAutomotive thanks for ur reply i really hope it fixes my leaks ill let u know i only drive like 6 miles a day so itll take me longer to hit 100 miles
No, I wouldn't do anything like that. AT-205 has a very long track record for being safe to use in all engines. I wouldn't do anything to it, then put it in one of my engines. If you have a minor oil leak just try it in its current form. If it does not work I'd look into changing the bad gasket. Thanks for watching. I hope you're a subscriber and make those cars last baby!
Hey I have a fairly new car 2015 Toyota Venza 84000 miles. It’s an extremely small rear main seal leak. I was saw a drop every time I drive. Would 205 stop this and be safe for this type of engine
Yes, as long as the car is out of warranty I wouldn't hesitate to try AT-205. I've had great results... and it's a major reason I'm getting 25 years and 300,000 miles out of my vehicles.
@@TheSwitzAutomotive yup..sub'd and yes, it's an '88 yota 4x4 with over 450k on it. took a few years to find and did one rebuild but after 8+ years it's got a leak.... I love older cars from the 80's, 90's more than the new ones. my job bought me a new 2020 taco (had 5 miles on it) and it was depressing b/c auto, 4cyl, 2wd.... my 88 has more torque at idle than the 2020 has at redline.
This additive will only help if the leak is caused by a hardened or flattened seal that the swelling compounds can cause to push out more. High mileage oil has the same swellers just in much lower concentrations as this stuff can destroy seals if they over expand. However, if the leak is due to a torn seal, failed seal spring, etc. it's not going to do anything.
@@Cragified Yep. That's how it works. So far in all my years AT-205 has never failed me. I'm just concerned about what I call the "reformulation" that does not seem (from my subscribers) to work as well. Thanks for watching! I hope you're a subscriber and make those cars last baby!
Did you get eyes on the leaking gasket/seal? Would be interested in if it was damaged or dried up. Since it will not seal anything, it only brings back dried up seals. Cracks, tears, and damage will not work with this product.
I started getting complaints from subscribers that it wasn't working as well. I still think it's the best on the market, but it's not quite what it was. Thanks for watching. I hope you're a subscriber VW guy... and make those VWs last baby!
WD-40 pulled the same stunt I had an old can and a compared to a newer can of WD-40 two totally different products the old stuff actually worked and stayed there for a while the new WD-40 evaporates after. 24 hours...
New and improved equals lower quality and worse outcomes. My guess is that it is now more profitable. Maybe car manufacturers have paid off the company to degrade this new version to make it less effective.
Gary, I've continued to research this and I think I'm on to something... the real reason why there's been a change in formulation. Stay tuned for a video in the future. I hope you're a subscriber and make those cars last baby!
I don't claim to be a scientist ... I claim to be a DIY guy whose made his cars last decades ... my crown jewel in my 4 car stable is a 1992 325i that still looks and runs excellent. AT-205 for decades has had the distinct nail polish smell... until recently. So something has changed. And my subs have complained about it not working as well - although I still think it's the best on the market. So I have something to offer people who are interested... make your cars last decades, get off the new car payment treadmill, and start getting ahead in life. Thanks for watching supergirl... if you're a scientist I'll let you handle the science... as long as it not the Fauci $cience.
I used this in my car 3 days ago and been driving. Have you heard of anyone mentioning there lifters were ticking on a cold start!?? Whats up with that? My lifters never ticked and I hope this will go away after driving more miles or with an oil change. I assume the solution is sticking to my lifters as it would to rubber seals.
Ha! Yes, it does appear like I'm gonna swig it down... nothing like a little after dinner AT-205. In all seriousness, this is a great product, but unfortunately it doesn't work as good as it used to. Thanks for watching. I hope you're a subscriber and make those cars last!
I went to smell it, a little went up my nose, a lil worried about cancer but my nose hasn't dripped ever since. Suggestion... what you were used to was actually rancid product that was warehoused until they could find a buyout company. You may have been using 10 year old product. Sorry bro, I don't trust your methods and experience. If its just a solvent missing, there are many many alternatives. I suggest that if the formula changed that the original high potency solvents may have worked well w dirtier engines, cutting thru grime and facilitating a raw bond of product to seal. Maybe this "new" formula is sufficient for cleaner engines? Do an oil change first. Also, I wouldn't worry too much about companies making greener formulas that aren't as effective, it hits home when you bury someone who died of chemical caused cancer. Believe me. I'm ok to avoid cancer and thank any company for formulating away from causing health defects. It happens w body building products a lot. Noone knows why a product dissapears, they know it worked better than the rest short term. Yet, cancer takes longer to express than it takes a stop leak to work. Dirty oil itself is cancer causing. Compounding carcenogens is not the answer. That said, I'm gonna use the stuff. Still a new car is cheaper than treating cancer (for most of us.)
Another reason to buy an EV. I dont miss gas fumes, smog checks, oil changes, tranny fluid changes, diff. oil changes etc etc I will use it on lall my rubber bushings on my 2017 Bolt.
You're not buying the smell, you are buying it's stop-leak ability. I just used this on my old car yesterday and today there is no more oil leak .
Yes, you may want to see my more recent videos where I talk about Project Farm testing AT-205. It's still the best out of all the stop leak products. I hope you're a subscriber Jona and make those cars last baby!

Believe me I wish I'd purchased 1000 bottles of AT-205 in 2015-2017. I could then sell them to my subscribers as needed to keep their cars on the road. All that said, the new formulation appears to work, just not as well. I'm doing some testing with it now. Thanks for watching.
@@TheSwitzAutomotive that be great man do you know if this sealer work in valve cover gaskets also? I have a 1995 4runner n it leaks from the valve covers
@@DanielAlvarez-xl4qy Yes, I've used AT-205 for valve cover gasket leaks. Thanks!
@@TheSwitzAutomotive thanks for ur reply i really hope it fixes my leaks ill let u know i only drive like 6 miles a day so itll take me longer to hit 100 miles
If the bottle doesn't have the nail polish smell..... could I add maybe eighth to quarter ounce of acetone maybe???
Thinking about it.... 🙄
No, I wouldn't do anything like that. AT-205 has a very long track record for being safe to use in all engines. I wouldn't do anything to it, then put it in one of my engines. If you have a minor oil leak just try it in its current form. If it does not work I'd look into changing the bad gasket. Thanks for watching. I hope you're a subscriber and make those cars last baby!
lmao
Make sure you tell you warranty company about that after you do it.😂
Hey I have a fairly new car 2015 Toyota Venza 84000 miles. It’s an extremely small rear main seal leak. I was saw a drop every time I drive.
Would 205 stop this and be safe for this type of engine
Yes, as long as the car is out of warranty I wouldn't hesitate to try AT-205. I've had great results... and it's a major reason I'm getting 25 years and 300,000 miles out of my vehicles.
I tried some...didn't work at all.
tried it in July 2022, no changes in small leak.
Yeah I've heard a lot more of this Lost Dragon. Hey, thanks for watching. I hope you're a subscriber and make those cars last!
@@TheSwitzAutomotive yup..sub'd and yes, it's an '88 yota 4x4 with over 450k on it.
took a few years to find and did one rebuild but after 8+ years it's got a leak....
I love older cars from the 80's, 90's more than the new ones.
my job bought me a new 2020 taco (had 5 miles on it) and it was depressing b/c auto, 4cyl, 2wd.... my 88 has more torque at idle than the 2020 has at redline.
This additive will only help if the leak is caused by a hardened or flattened seal that the swelling compounds can cause to push out more. High mileage oil has the same swellers just in much lower concentrations as this stuff can destroy seals if they over expand. However, if the leak is due to a torn seal, failed seal spring, etc. it's not going to do anything.
@@Cragified Yep. That's how it works. So far in all my years AT-205 has never failed me. I'm just concerned about what I call the "reformulation" that does not seem (from my subscribers) to work as well. Thanks for watching! I hope you're a subscriber and make those cars last baby!
Did you get eyes on the leaking gasket/seal? Would be interested in if it was damaged or dried up. Since it will not seal anything, it only brings back dried up seals. Cracks, tears, and damage will not work with this product.
Ok it's different now but how do you know it's not a better improved formula now?
I started getting complaints from subscribers that it wasn't working as well. I still think it's the best on the market, but it's not quite what it was. Thanks for watching. I hope you're a subscriber VW guy... and make those VWs last baby!
Viewed video's on it. Didn't work for me on two different occasions, and made absolutely no difference
Yes, I don't think it's as good as the original formulation. Still the best on the market, but definitely no guarantees. Thanks for watching!
WD-40 pulled the same stunt I had an old can and a compared to a newer can of WD-40 two totally different products the old stuff actually worked and stayed there for a while the new WD-40 evaporates after. 24 hours...
New and improved equals lower quality and worse outcomes. My guess is that it is now more profitable. Maybe car manufacturers have paid off the company to degrade this new version to make it less effective.
Gary, I've continued to research this and I think I'm on to something... the real reason why there's been a change in formulation. Stay tuned for a video in the future. I hope you're a subscriber and make those cars last baby!
This is sure some scientific study. If you are going for the smell then just use your wife nail polish remover.
I don't claim to be a scientist ... I claim to be a DIY guy whose made his cars last decades ... my crown jewel in my 4 car stable is a 1992 325i that still looks and runs excellent. AT-205 for decades has had the distinct nail polish smell... until recently. So something has changed. And my subs have complained about it not working as well - although I still think it's the best on the market. So I have something to offer people who are interested... make your cars last decades, get off the new car payment treadmill, and start getting ahead in life. Thanks for watching supergirl... if you're a scientist I'll let you handle the science... as long as it not the Fauci $cience.
Woww to bad I won't be buying it no longer.
I used this in my car 3 days ago and been driving. Have you heard of anyone mentioning there lifters were ticking on a cold start!?? Whats up with that? My lifters never ticked and I hope this will go away after driving more miles or with an oil change. I assume the solution is sticking to my lifters as it would to rubber seals.
It’s a smelling test😂
How does it taste? 🤣
Ha! Yes, it does appear like I'm gonna swig it down... nothing like a little after dinner AT-205. In all seriousness, this is a great product, but unfortunately it doesn't work as good as it used to. Thanks for watching. I hope you're a subscriber and make those cars last!
if its not broke, don't fix it... why would they change it... soo sad
I went to smell it, a little went up my nose, a lil worried about cancer but my nose hasn't dripped ever since.
Suggestion... what you were used to was actually rancid product that was warehoused until they could find a buyout company. You may have been using 10 year old product. Sorry bro, I don't trust your methods and experience.
If its just a solvent missing, there are many many alternatives. I suggest that if the formula changed that the original high potency solvents may have worked well w dirtier engines, cutting thru grime and facilitating a raw bond of product to seal. Maybe this "new" formula is sufficient for cleaner engines? Do an oil change first. Also, I wouldn't worry too much about companies making greener formulas that aren't as effective, it hits home when you bury someone who died of chemical caused cancer. Believe me. I'm ok to avoid cancer and thank any company for formulating away from causing health defects. It happens w body building products a lot. Noone knows why a product dissapears, they know it worked better than the rest short term. Yet, cancer takes longer to express than it takes a stop leak to work. Dirty oil itself is cancer causing. Compounding carcenogens is not the answer. That said, I'm gonna use the stuff. Still a new car is cheaper than treating cancer (for most of us.)
Another reason to buy an EV.
I dont miss gas fumes, smog checks, oil changes, tranny fluid changes, diff. oil changes etc etc
I will use it on lall my rubber bushings on my 2017 Bolt.
I use "SEAL FIXX"... It works just like the old AT 205 Reseal for less money.
