I saw your video on using 205 product and I had a customer 2003 5.9 dodge ram van with a leaking rear main seal and it was 2 quarts low in oil so I open each quarts and pour half of into the engine and bought 2 bottles of the 205 and I added 1 bottle of the 205 to each quart of oil and shook it up and with the engine running I added to the motor and let it run for a hour the leaking stop and hasn't returned I'm a mechanic of 40 + yrs and this is the best product I've ever used .ken's automotive God bless you
I poured a bottle of AT 205 in my 2000 Mercedes E 430 about a year ago for a rear main seal leak that was dripping oil on my driveway. It cleared up most if not all of the leaking. I think it works by "plumping up" the rubber in the seal, which effectively accomplishes the same thing as installing a new seal. Saved me about $1,200, so I would recommend it. Just make sure not to overfill the crankcase.

Yah Jags are junk. First in England then Ford bought them and lost hundreds of Millions then India now China. They are horrible cars. Like BMWs and Volvos and Saabs and Audi! And Range Rovers are the worst. But some how you can’t tell people that those cars are money pits and depreciation is horrible!
AT-205 contains a similar ester that is used in ‘High Mileage Engine Oil’ for the same purpose. I have successfully used this product in engine oil, transmission and power steering fluid. Have some in a spray bottle for rubber suspension bushings and boots. It has stopped leaks and squeaks for me in all applications! Great stuff.
I used this on a 2004 Chevy Cavalier with a 2.2 eco tech engine. This engine had bad valve seals which caused a little smoke occasionally on acceleration plus the 200k mile engine had minor oil leaks. I added with a fresh oil change. After a few days the smoke stopped and no more oil leaks. That was over a year ago. Well worth it on an old beater car for sure!
I have my second Jag and they are easy to take care of...Preventative maintenance is key. Main issues are the same, water cooler, fuel pump failure...Anything electric, first culprit will be the battery so get a bigger battery than needed. Along as you regularly change oil, you'll enjoy that, Jag. I DIY all my repairs, mods and upgrades. Just changed my oil, oil filter, oil sump gasket on my Jag Xf R and but still used the AT 205 even though i have no leaks...Good video
I have a 2016 JK with a rear main seal leak I change my oil and put in a bottle of this product within 2500 miles the leak has all but completely stopped my jeep made a mess wherever I parked it and now there is no reason for me to make the repair I highly recommend this product it save me about $1000 at least for now maybe one day it’ll start leaking again but every time I change my oil I will be adding this absolutely amazing and I highly recommend it
I don't see a leak on the ground but I have these pictures underneath with oil residue. A mechanic says it's the rear seal though. Nothing on the ground.

This saved me over $60,000.00 My run-flat tires are still good, maybe dry-rot but no cracks. I uses nitrogen air & no leaks.
You have to use this at every oil change or the leak will return. I use this in my 2002 Honda CR-V with 352,000 miles. This is not a sealer per se, but a rubber conditioner that rejuvenates the rubber seals.
this stuff is awesome if you have noisey a-frame bushings. i do know that it takes time for the rubber to expand in the way i use it. then it works for a long time
@@JohnEngel scotty kilmer did a video on it. because of covid this product is out of stock everywhere. apparently dot4 breakfluid has the same base ingredients as at-205.
Team 512 that’s a great point. I hadn’t even thought of that aspect. I am sure there are some dealerships that would do this rather than spend the money to do it right.
Hi i tried this on my 25 year old Seat TDI (VAG) gearbox engine seal went and it works.. but you need to add just a little of it at each oil change just 3 or 4 caps
From my own experience most of the top end rubber seals (cam adjuster seal, spark plug tube seals) on my audi 3.2 were leaking oil and brittle plastic when replaced, had to be picked out in small pieces brittle. Audi engines run absurdly hot under normal use and if i knew the limited longevity of the seals I would of considered adding the occasional additive with rubber plasticiser well in advanced, including gear boxes and differentials. Contrary to not adding it to the car you love I would recommend it. High millage oils already contain seal conditioners and o-ring lubricants promote swelling for proper seating right at the installation. Seal conditioners for rubber swelling is nothing new or something to be fearful, you just dont want to use incompatible chemicals that deteriorate rubber.
@@JohnEngel Im going to try Bluedevil in a differential and engine case, only because of easy availability and BD is exactly the same ethylene glycol as at-205. EG seems to swell the rubber but almost all rubbers have excellent chemical resistance to EG
Glycol ethers (a class or range of chemicals rather than a single one), a major component of standard brake fluid, is different from Ethylene Glycol, the major component of anti-freeze. And rubber-like elastomers are NOT resistant to it (the AT-205, Blue Devil, any others? dunno), which is why it (sorta) works. Put it in a cooling system and it would eventually ruin the hoses.
@@denniswhite4446 My bad, the chemical is Di(ethylene glycol) ethyl ether, im not a chemist but my understanding is that it softens rubber. The product is only to be used in hydraulic systems, not brake or cooling systems.
AT 205 used to be sold in an aerosol spray as well and the purpose was to saturate all the rubber parts of your suspension underneith the vehicle. More specifically the parts of your susension located nearest to each tire. I am thinking of pouring a bottle of this into a spray bottle specifically for my suspension issues. It supposidly rejuvinates rubber parts through absorbsion. Quiets noises of rattles and squeeks and the like along with prolonging the life of the parts be they bushings, seals, boots, or whatever. In other words it makes for a great preventative to deter dry rotting and normal deterioration. The fact that this is the case should indicate how it works in any of its aplications. It rejuvanates the seals where you may have an oil leak as long as the seals in question are not too badly damaged already through deterioration, or suffer from rips, or tears.
@@JohnEngel ... I really can't take credit for the idea. Just for bringing it to peoples attention who drop by here. I will leave two links on UA-cam from where I got the idea from. Think of them as source footnotes so everyone knows I am not talking through my butt with the idea. #1(ua-cam.com/video/VYuF02wTx8w/v-deo.html) and #2(ua-cam.com/video/rE4Q9LZ73Ms/v-deo.html)
If you search you might be able to find a video by the Scotty Kilmer Channel. He very highly recommends this product for internal engine use, and does put it in a spray bottle and sprays suspension components just like you mentioned. He does exactly that and there's a video of him showing him doing it. Explains that ATT 205 is a type of polymer that rejuvenates and softens hard rubber suspension components and engine seals
@@deplorabledave1048 I have seen the Scotty video and I have in fact since used it with confidence. Only used it as a preventative so far. Not to try and stop a leak as I have not had a leak to use it on yet.
Had my oil changed in my 2008 Toyota Sequoia Limited with over 210,000 miles the other day at Toyota and they said my rear main seal was leaking,$3680 fix,thats definitely not happening,I'll let my personal mechanic look at it and see what he says,I'll most likely be giving this stuff a try,really good video my man 🙏🏾
It would have helped to show oil dipstick levels before and after. You may have less oil leaking because you have less oil to leak... but nice vid. I'll try it in my old Rav4.
Never thought about that but the oil level was always 3/4 of the stick. The leak did come back after the first oil change. I was told that you’re supposed to use this with every oil change.
i putthis in my grand prix , my car has more compression and runs great .a lot better than before.as for the leak i had was on the oil send relay it did not stop that leak as i replaces that sender unit..
Hi Thank you for all your wonderful videos, they help a lot to a lot of people (including me). I would like to ask you: Is this product good when the car has a little blue smoke from time to time? So can I put it in the engine? or you have another product to suggest.Thanks again.
Thank you so much. So with blue smoke you are getting oil in the combustion chamber. This product could help with that but it really depends on where the oil is coming from. Once you figure that out, you will be able to guess how well it will work.
I'am Your Newest Subscriber Great Videos . The Chevy Astro Van I Bought Leaks From The Rear Main Seal . I Put Blue Devil Rear Main Sealer In And It Didnt Work At All
They use this stuff in the Aircraft Industry/Engines, on Rubber Seals, because it works. Think about that the next time you trust your life to an airplane.
@@RiteSideUp__ shadowops has a valid question. He's not questioning a comment like "yeah it really works" if you gonna comment something like The FAA using these products on airplanes, well remember it's youtube and people are gonna ask for links to educate themselves on it, not necessarily to troll. Writing these kind of comments can also be seen as advertising the product to have people believe, that if it's good for the FAA to use on airplanes, then it's good and safe for them to use on their vehicles. It's fair to ask where this information came from....👍
@@RiteSideUp__ FAA has actual aircraft "laws" (FAR's) of acceptable repair methods following the manufactures suggestions. . You cant just do what you want, since people can die.
Thanks for the video. Please clarify how to tell if your oil pan is "coated in rubberized plastic". I own a 2001 XK8. The oil pan looks metal from underneath. Thanks!
Thank you. The easiest way would be to search on Google for an OEM replacement oil pan and see if it has the coating. If it doesn’t then you’ll be safe to use.

@@andybilakshow260 I'm thinking In your case you've got nothing to lose. Try changing the oil and dump in a bottle, drive it around for a few days and see what happens. If it's really leaking a lot it might not work 100% but it's certainly worth a try.
Used it on a camry cut the leak to 1/10 of what it was. Rear seal used two bottles first one drove it 400 miles still leaked added another than started working.
I believe the rear main seal on the GMC SUVs is made of Teflon, not rubber, that at205 likely to be harmful. ? However may prolong life of the oil pickup tube o-ring.

I have a 2005 Cadillac DTS with the famous North Star engine that starts leaking oil around 65,000 MI. My oil leak is slight but annoying. On my last oil change the mechanic put in 8 quarts of synthetic oil. Now I am leaking a little more oil than with conventional oil. My car is in excellent showroom condition with only $108,000 MI. I am hesitant in putting in the oil stop leak. I asked a couple mechanics what do they think of using the stop leak they said it's like playing Russian roulette if it works fine if it don't work you can ruin your engine. Still thinking it over what to do. One thing I do know is switching back to conventional oil.
Great question. I can tell you that synthetic cleans your engine much better and that is what caused more leaking. once this has happened going back to conventional will not slow the leak, as the area that leaks has been cleaned and that is why it is leaking more. Using this product could help with the seals, but it is always a gamble. How hard would it be to fix the leak with new seals?
@@JohnEngel in the past several mechanics that I brought the car to said it's a hard and costly job. You are right when you said that the synthetic oil removed a lot of that old oil and that is why it's leaking more than usual. Overall it's still not bad I only top it off about once a month with about 3 to 4 ounces of new oil. I got my driver's license in 1952 and the cars that I had from the 1940s I was putting in about a quart of oil every week or maybe sooner. You needed a ring job on those engines about 65 to 70 thousand miles back then.
@@johnraymond4322 it all depends on how much the car is worth to you. With the Jag I used, I would have been okay with the engine being destroyed as it would cost more to fix the problem than the car itself.
@@JohnEngel I would get my car fixed if I was a little younger at 86 years old and with the coronavirus going on who knows how much time I got left. Right now I take one day at a time.
@@johnraymond4322 I understand completely. With all of those factors in place, I would just drive the car and top it off every month. Happy new year and stay healthy. :)
Hey, great video. Solid information! 8 months after the postage of this video: has the leak reappeared? Or has this product fixed the problem for good?
It has come back. :( I’m sad to say that it only worked for a short period of time. I was very hopeful but at the end of the day I think my leak was too much.
@@JohnEngel It might be a good Idea to try at least 3 more bottles to see if depending on the leak type it will work on the other additonal tries since it's a polymer and enough product needs to fill the gap that's causing the leak. worth the try. best of luck!
Some people say that i must put the product and them drive for at least an hour... is this true? Some people say they had problems because they didnt drive after using the product. So i dont know what to do.. and the box doesnt say anything about moving the car just after using it... can you tell me? Thanks. Btw. Great video
C. Galves the driving or hours gives it times to circulate the product into all of the seals. If you just put it in and let it sit it will not get a chance to work on the rubber.
I put at-205 in my lawn mower and only ran for a few minutes and the leak is still there. So, I will pour the old leaking oil back in until the leak stops. lol
Thanks for your sharing. I am not sure about that: Do you need to re-add AT-205 with every Engine-oil change? Or just one shot to cure the oil leaking?
@@JohnEngel Interesting in light of Scotty Kilmer saying it was some type of polymer fluid that helped refurbish the rubber seals. Seems like if that were the case it might need redoing some but not every oil change. Have you tried other stop leaks like Lucas?
@@mickjager5974 I love Scotty’s videos and he is exactly right. I have not been using it with every oil change and my leak came back. I was told by others that have used it that it needs to be reused each time. I’m thinking about trying another brand.
How many miles did you have on that jaguar when it started leaking? I just put two bottles of Bars rear main seal stop leak with clean oil in my 2007 Tahoe with 313K miles. The leak was slow and barely noticeable, hope it works. If it does not work i will use the ATP 205.
Tried another brand first ran it for a month did nothing to stop my rear main seal from leaking , changed my oil and filter put AT-205 in and an hour later leak has practically stopped 👍
Stop leak does not work good (or even not at all) with hyper modern rubber seals, the brown and blue ones are Viton or Neoprene seals...they are resistent. Stop seal works best with BUNA (synthetical black rubber seals = NBR) On vintage cars with NBR rubber gaskets most stop leak additives work pretty well.
Yup, if you like fluid leaks, buy a jaguar I ordered some to try on a rather bad xmission leak on my DTS. Considering accounts that this stuff can cause the seals to swell excessively I wondered if, if it stops the leak, would it be a good idea, at that point, to drain the fluid and refill w/fresh fluid to prevent any further swelling of the seals. What do you think?

ATG, SAS, Scott Kilmer & experts like this product.
You have no problem putting it into your Bentley. I used it on mine & my uncle's 959
WOW. I am a huge 959 fan. Always loved them.
@@JohnEngel My uncle & I also tested on TPMS. But decided to replaced the TPMS.
Four TPMS hit over $60,000.00 for my uncle car.
Four TPMS price made four Bridgestone tires like almost free.
I rather use my money on fine wines & jewelry & photo equipment.
Can't drive all five cars as the same time. My 959 is mostly parked on Jack Stands.
My projects on my car:
1. Removed 4 TPMS
2. Soaked in Lime Juice (ATG stated great for rusted bolts & nuts)
3. Soaked & Pressure Vacuumed TPMS for 1 week
4. TPMS installed with light coat of high temp silicone
5. This saved me over $60,000.00
My run-flat tires are still good, maybe dry-rot but no cracks.
I uses nitrogen air & no leaks.
No guarantee it will work but cheap enough to try. I add 1/3rd of the maximum dose to each oil change as preventative maintenance.
This product is fine to use in expensive cars it won’t hurt them! If it does not fix the problem your in the same boat of repairs! Just FYI
Im getting some of the AT205 for my old 1995 Land Rover Disco ,it will be interesting to see
It really does a great job on smaller leaks. Keep us posted.
love the jag x type
You have to use this at every oil change or the leak will return. I use this in my 2002 Honda CR-V with 352,000 miles. This is not a sealer per se, but a rubber conditioner that rejuvenates the rubber seals.
Exactly.
Much appreciated because he never said that in the video...
I had excellent results with the Blue Devil stop leak.
Well, it's called a re-sealer...
No. It is not petroleum based. One time use can keep you long time.
this stuff is awesome if you have noisey a-frame bushings. i do know that it takes time for the rubber to expand in the way i use it. then it works for a long time
That’s a great idea.
@@JohnEngel scotty kilmer did a video on it. because of covid this product is out of stock everywhere. apparently dot4 breakfluid has the same base ingredients as at-205.
I wonder how many used car kits stockpile this stuff. Glad it worked out. Keep us posted.
Team 512 that’s a great point. I hadn’t even thought of that aspect. I am sure there are some dealerships that would do this rather than spend the money to do it right.
Tried this in my 1986 carver 32' boat transmission, 2 years ago still no leaks, just put some in my starboard transmission yestrday
Starboard transmission, no leak now.
Great video...good talker, my man. you solved the mystery a lot of us, were wondering, ty
Thank you so much.
Hi i tried this on my 25 year old Seat TDI (VAG) gearbox engine seal went and it works.. but you need to add just a little of it at each oil change just 3 or 4 caps
Great info.
From my own experience most of the top end rubber seals (cam adjuster seal, spark plug tube seals) on my audi 3.2 were leaking oil and brittle plastic when replaced, had to be picked out in small pieces brittle. Audi engines run absurdly hot under normal use and if i knew the limited longevity of the seals I would of considered adding the occasional additive with rubber plasticiser well in advanced, including gear boxes and differentials.
Contrary to not adding it to the car you love I would recommend it. High millage oils already contain seal conditioners and o-ring lubricants promote swelling for proper seating right at the installation. Seal conditioners for rubber swelling is nothing new or something to be fearful, you just dont want to use incompatible chemicals that deteriorate rubber.
That’s a great point. It would have been nice to add this before the leaks and see if it would have conditioned the seals.
@@JohnEngel Im going to try Bluedevil in a differential and engine case, only because of easy availability and BD is exactly the same ethylene glycol as at-205. EG seems to swell the rubber but almost all rubbers have excellent chemical resistance to EG
Glycol ethers (a class or range of chemicals rather than a single one), a major component of standard brake fluid, is different from Ethylene Glycol, the major component of anti-freeze. And rubber-like elastomers are NOT resistant to it (the AT-205, Blue Devil, any others? dunno), which is why it (sorta) works. Put it in a cooling system and it would eventually ruin the hoses.
@@denniswhite4446 My bad, the chemical is Di(ethylene glycol) ethyl ether, im not a chemist but my understanding is that it softens rubber. The product is only to be used in hydraulic systems, not brake or cooling systems.
Audi ‘s are money pits and nothing but trouble. Super expensive to fix and constant problems. BMWs are horrible too.
AT 205 used to be sold in an aerosol spray as well and the purpose was to saturate all the rubber parts of your suspension underneith the vehicle. More specifically the parts of your susension located nearest to each tire. I am thinking of pouring a bottle of this into a spray bottle specifically for my suspension issues. It supposidly rejuvinates rubber parts through absorbsion. Quiets noises of rattles and squeeks and the like along with prolonging the life of the parts be they bushings, seals, boots, or whatever. In other words it makes for a great preventative to deter dry rotting and normal deterioration. The fact that this is the case should indicate how it works in any of its aplications. It rejuvanates the seals where you may have an oil leak as long as the seals in question are not too badly damaged already through deterioration, or suffer from rips, or tears.
That’s a great idea. Let me know how it goes.
@@JohnEngel ... I really can't take credit for the idea. Just for bringing it to peoples attention who drop by here. I will leave two links on UA-cam from where I got the idea from. Think of them as source footnotes so everyone knows I am not talking through my butt with the idea. #1(ua-cam.com/video/VYuF02wTx8w/v-deo.html) and #2(ua-cam.com/video/rE4Q9LZ73Ms/v-deo.html)
If you search you might be able to find a video by the Scotty Kilmer Channel. He very highly recommends this product for internal engine use, and does put it in a spray bottle and sprays suspension components just like you mentioned. He does exactly that and there's a video of him showing him doing it.
Explains that ATT 205 is a type of polymer that rejuvenates and softens hard rubber suspension components and engine seals
@@deplorabledave1048 I have seen the Scotty video and I have in fact since used it with confidence. Only used it as a preventative so far. Not to try and stop a leak as I have not had a leak to use it on yet.
Had my oil changed in my 2008 Toyota Sequoia Limited with over 210,000 miles the other day at Toyota and they said my rear main seal was leaking,$3680 fix,thats definitely not happening,I'll let my personal mechanic look at it and see what he says,I'll most likely be giving this stuff a try,really good video my man 🙏🏾
I think that would be a perfect use for this product.
How did it go?
@@jaydu2970Really good,the leak is really small,I might notice a drip like every 3 weeks or longer...
It would have helped to show oil dipstick levels before and after. You may have less oil leaking because you have less oil to leak... but nice vid. I'll try it in my old Rav4.
Never thought about that but the oil level was always 3/4 of the stick. The leak did come back after the first oil change. I was told that you’re supposed to use this with every oil change.
@@JohnEngel Scotty Kilmer said to use it during every oil change, also.
i putthis in my grand prix , my car has more compression and runs great .a lot better than before.as for the leak i had was on the oil send relay it did not stop that leak as i replaces that sender unit..
Jack Smith Unfortunately, my leak returned. :(
Works thumbs up
This solved a minor oil leak on an Acura MDX rear main seal. Also a cam shaft seal leak(bad one) on a Honda civic which was very old and high mileage.
This product seem to work best on the small leaks. Glad to hear that it worked and helped.
G r e a t Bill ! Nice to hear that . . .
Passed down a 2009 Prius to my son. Thinking about recommending AT-205 to pre-empt any seal leaks...
t swartzbaugh that’s a good idea. Seeing it rejuvenates the rubber it couldn’t hurt.
He would be happier if you got him a real car
I will try this one to see if it will work
I used this in my forklift engine that was leaking badly from the main seal. It took about a week, but it finally stopped the leak.
That's awesome and thank you for the comment.
My beater is a Jag. That's fricken hilarious dude. Thanks for the review though, very helpful.
Hi Thank you for all your wonderful videos, they help a lot to a lot of people (including me). I would like to ask you: Is this product good when the car has a little blue smoke from time to time? So can I put it in the engine? or you have another product to suggest.Thanks again.
Thank you so much. So with blue smoke you are getting oil in the combustion chamber. This product could help with that but it really depends on where the oil is coming from. Once you figure that out, you will be able to guess how well it will work.

They use this stuff in the Aircraft Industry/Engines, on Rubber Seals, because it works. Think about that the next time you trust your life to an airplane.

You have an FAA reference for it or from an Aircraft Maintenance Manual or Engine Overhaul Manual?

He's not questioning a comment like "yeah it really works" if you gonna comment something like The FAA using these products on airplanes, well remember it's youtube and people are gonna ask for links to educate themselves on it, not necessarily to troll.
Writing these kind of comments can also be seen as advertising the product to have people believe, that if it's good for the FAA to use on airplanes, then it's good and safe for them to use on their vehicles.
It's fair to ask where this information came from....👍
@@RiteSideUp__ FAA has actual aircraft "laws" (FAR's) of acceptable repair methods following the manufactures suggestions. . You cant just do what you want, since people can die.
Thanks for the video. Please clarify how to tell if your oil pan is "coated in rubberized plastic". I own a 2001 XK8. The oil pan looks metal from underneath. Thanks!
Thank you. The easiest way would be to search on Google for an OEM replacement oil pan and see if it has the coating. If it doesn’t then you’ll be safe to use.

@@andybilakshow260 I'm thinking In your case you've got nothing to lose. Try changing the oil and dump in a bottle, drive it around for a few days and see what happens. If it's really leaking a lot it might not work 100% but it's certainly worth a try.
Thanks for showing us this experiment. What's the latest update on this as it was carried out in Mar-2020. Thanks
uhjk91 the came back. :( it’s not any worse but exactly how it was.

Does this work for leaking head gasket or hardened valve seals? .. running a 2006 Swift petrol and on every 1st cold start, tail pipe emits crazy white smoke all over the place for 10 minutes

How do you check to make sure your oil pan doesn't have paint?
Most of the time you will see that your oil pan is black on the outside and not metal. You would need to check with the manufacturer to make sure.
Hi my tiida transmission leak help this work
Putting card board under your oil pan is a better than having oil drip on your garage floor.
Lol.
I have a 2005 Cadillac DTS with the famous North Star engine that starts leaking oil around 65,000 MI. My oil leak is slight but annoying. On my last oil change the mechanic put in 8 quarts of synthetic oil. Now I am leaking a little more oil than with conventional oil. My car is in excellent showroom condition with only $108,000 MI. I am hesitant in putting in the oil stop leak. I asked a couple mechanics what do they think of using the stop leak they said it's like playing Russian roulette if it works fine if it don't work you can ruin your engine. Still thinking it over what to do. One thing I do know is switching back to conventional oil.
Great question. I can tell you that synthetic cleans your engine much better and that is what caused more leaking. once this has happened going back to conventional will not slow the leak, as the area that leaks has been cleaned and that is why it is leaking more. Using this product could help with the seals, but it is always a gamble. How hard would it be to fix the leak with new seals?
@@JohnEngel in the past several mechanics that I brought the car to said it's a hard and costly job. You are right when you said that the synthetic oil removed a lot of that old oil and that is why it's leaking more than usual. Overall it's still not bad I only top it off about once a month with about 3 to 4 ounces of new oil. I got my driver's license in 1952 and the cars that I had from the 1940s I was putting in about a quart of oil every week or maybe sooner. You needed a ring job on those engines about 65 to 70 thousand miles back then.
@@johnraymond4322 it all depends on how much the car is worth to you. With the Jag I used, I would have been okay with the engine being destroyed as it would cost more to fix the problem than the car itself.
@@JohnEngel I would get my car fixed if I was a little younger at 86 years old and with the coronavirus going on who knows how much time I got left. Right now I take one day at a time.
@@johnraymond4322 I understand completely. With all of those factors in place, I would just drive the car and top it off every month. Happy new year and stay healthy. :)
What if you don't drive right away after putting it in?
Hey, great video. Solid information!
8 months after the postage of this video: has the leak reappeared?
Or has this product fixed the problem for good?
It has come back. :( I’m sad to say that it only worked for a short period of time. I was very hopeful but at the end of the day I think my leak was too much.
@@JohnEngel I was reading you suppose to add a new bottle of this every time you change the oil for long lasting results.
@@MAJAWAR I need to try it again.
@@JohnEngel try the Bars rear main seal stop leak. Supposedly only have to do it once, not every time you change your oil....
Worked in my 2010 328 xi
Glad to hear. My leak has come back so I hope yours wont. :)
How many bottles did you use?
Kiwi Wewi just the one.
@@JohnEngel It might be a good Idea to try at least 3 more bottles to see if depending on the leak type it will work on the other additonal tries since it's a polymer and enough product needs to fill the gap that's causing the leak. worth the try. best of luck!
Some people say that i must put the product and them drive for at least an hour... is this true? Some people say they had problems because they didnt drive after using the product. So i dont know what to do.. and the box doesnt say anything about moving the car just after using it... can you tell me? Thanks.
Btw. Great video
C. Galves the driving or hours gives it times to circulate the product into all of the seals. If you just put it in and let it sit it will not get a chance to work on the rubber.
I put at-205 in my lawn mower and only ran for a few minutes and the leak is still there.
So, I will pour the old leaking oil back in until the leak stops. lol
Lmao. I am so scared for this lawn mower.
Good job Gamecock!
They are my team. :)
Thanks for your sharing. I am not sure about that: Do you need to re-add AT-205 with every Engine-oil change? Or just one shot to cure the oil leaking?
Every oil change. :(
@@JohnEngel Sad, it will cost a lot :(
@@JohnEngel Interesting in light of Scotty Kilmer saying it was some type of polymer fluid that helped refurbish the rubber seals. Seems like if that were the case it might need redoing some but not every oil change. Have you tried other stop leaks like Lucas?
@@mickjager5974 I love Scotty’s videos and he is exactly right. I have not been using it with every oil change and my leak came back. I was told by others that have used it that it needs to be reused each time. I’m thinking about trying another brand.
How many miles did you have on that jaguar when it started leaking? I just put two bottles of Bars rear main seal stop leak with clean oil in my 2007 Tahoe with 313K miles. The leak was slow and barely noticeable, hope it works. If it does not work i will use the ATP 205.
Mine had 140k miles. It did a great job but I had to add it to the oil each oil change.
Does this also work on the transmission? I can't reach the location its leaking from
It does. :)
Tried another brand first ran it for a month did nothing to stop my rear main seal from leaking , changed my oil and filter put AT-205 in and an hour later leak has practically stopped 👍
That is exactly the same same situation I found. I had tried STP before this and it did not stop the leak but AT 205 sure did.
@@JohnEngel i used Rislone first was a waste of money
@@Lord-hoboco777 good to know. Thank you.
i wonder if you do an oil change if your need to pour a bottle again
Unfortunately, from my experience, every oil change will require a new bottle to be added.
Stop leak does not work good (or even not at all) with hyper modern rubber seals, the brown and blue ones are Viton or Neoprene seals...they are resistent. Stop seal works best with BUNA (synthetical black rubber seals = NBR) On vintage cars with NBR rubber gaskets most stop leak additives work pretty well.
Thank you for the comment. I would agree 100% with what you said.
For how long this additive does it works. Did you had any drops after oil change?
Lasted a couple months on mine.
Will this qualify to help stem valve seals? Thanks
I believe so.
My 1979 corvette is leaking from the front seal of the transmission and it’s a bad leak. I’m hoping this will slow the leak down or completely stop it
Djentyman I will tell you that my leak did come back. :(
@@JohnEngel well I may have to bite the bullet and replace the front seal. $10 part but hours to remove the transmission ;(
Djentyman that was my issue with the x type. It just takes so long for a small leak.
@@JohnEngel and my leak is a big leak. Loses half a quart over night so maybe stop leak wouldn’t even fix the issue
Djentyman yeah, I don’t think this would even touch that. Lol. Good luck on the install. :)
Where do we check if our oil pan is painted or not?
khompressor I just looked at the oil pan. If it’s painted it will be black and if not it will be Metal. This is not 100% but worked for me.
Can I used it to put it in sealer in the cam tower not the gasket the sealer one tundra 2007
I am not sure what type of seal that is.
Would this stop a timing chain cover leak?
If it’s a small leak it could help with that.
If it can fix a Jaguar it can fix anything nice case study.
Lol. Good point.
Can I use this on a leaky motorcycle valve cover?
Yes you can. :)
Yup, if you like fluid leaks, buy a jaguar
I ordered some to try on a rather bad xmission leak on my DTS. Considering accounts that this stuff can cause the seals to swell excessively I wondered if, if it stops the leak, would it be a good idea, at that point, to drain the fluid and refill w/fresh fluid to prevent any further swelling of the seals. What do you think?
Frank S that’s a great question. I think if that’s something that worries you then the flush would be a good peace of mind.

Does it say to change the oil before and after?
It only states to add to your oil. I added it to my oil when it was just changed.
I have a car that doesnt really have any leaks but comsumes/burns oil. Do you think that product would help that?
If it’s seals, then it could.
If it's the intake valve seals you might get lucky, if it's the rings... no. Only works on rubber.
I have a 05 Toyota Tundra how do you find out if the oil pan is coated in a rubberized plastic???
If you look under the car at the oil pain is it metal or black. You can also look up your oem part and see.
