I had an expensive rear main seal leak on my BMW X5 V8 & the car was unlicensed & needed to go over the pit licensing inspection. I put this product in, clicked up the suggested driving time (with a permit) & it actually really fixed the problem. Not just that seal but also the rocker cover gaskets stopped leaking too. I passed the pits & never had a leak since. I’m blown away how good this stuff is!
@@danlonick800 Wow, I know you were relieved! I can only imagine what kind of a job a rear main would have been on an X5. Good stuff, thanks for hanging out and sharing!
Had a 2005 x3 3liter, same rear main leak... this stuff is magic. Worked perfect. Some returned with an oil change (synthetic oil leaks easier) but a re-treat fixed it. 200k miles on this motor.
@gregburrows4192 Thanks for sharing Greg, yes I love this stuff, it has served me well, and I too have had to add a second treatment, which is totally fine with me!
Used a bottle of this stuff on a 4 cyl tacoma which had a rear main seal leak, within 30 mins i had already noticed a difference. 2 hours into the engine running the leak was completely gone. Stuff really works.
This stuff worked for my jeep rear main seal leak. However, when the winter came, she started leaking again. I assume the cold weather shrinks the seal so not sure another bottle of reseal would help. But during the spring and summer I had no leak. Stuff is also great for bushings and suspension.
@@tdz69 Cold weather definitely impacts seals for sure. I would try another bottle and make sure to add it just before driving it (preferably when it'll be running a couple of hours) and see how it fairs. I'm like you, I've used it on suspension parts too, great stuff 👍 Thanks for sharing!
My GF's 4Runner had the exact same situation. We had the oil pan gasket changed with no luck so had the rear main seal changed. Egads, no change! A couple of oil changes later, I changed the drain plug and SHAZAM, no more oil leaks! It must have been the way air was being channeled under the motor. But back to AT205, I've had great success with it on my power steering units on my 4Runner and Chevy Express van. It usually lasts about 2 years before I need to add AT205 again. Yeah yeah I know I should have it repaired, but AT205 is much cheaper than a new unit.
Thanks for that story, I love hearing testimonials like that. And yes...we all should get these leaks fixed, self included, but hey $20 for a bottle of this stuff and it works so well...hard to argue against it! (I like your name by the way)
AT-205 is awesome stuff and I've been using it for years! some good things to know about it - 1: you need to run the car with the AT-205 in it for 5 hours for full effect - that's why it took you a few days & some additional driving to fully fix the leak. 2: AT-205 separates from your oil within minutes after shutting off the motor and sits in a layer at the bottom of your oil pan. that can sometimes be problematic with painted or plastic oil pans if you leave it in there. it's also why you need to run it for 5 hours - when the oil isn't actively circulating, the AT-205 is all at the bottom of the pan instead of treating your seals. 3: I wouldn't leave it in the oil for much longer than the necessary 5 hours of runtime, it thins the oil a bit and it won't protect as well over the long run. 4: you can use it with your old oil just before an oil change. unless your oil is in such awful shape that you can't stand the thought of running it another 5 hours, no reason to have to do 2 oil changes in a row. the oil's just the carrier for this stuff. 5: you can pour this stuff into a SPRAY BOTTLE and turn back the clock on ANY rubber parts - hoses, suspension & subframe bushings, window/door/sunroof seals, etc. hugely benefit from this. it softens and rejuvenates rubber and prevents it from drying and cracking. just don't get it on stuff like leather, cloth, or plastic trim bits or it can stain.
@@motorwolfe Hey thanks for the tips, I love to hear everyone's personal experiences with this additive and the way/method everyone uses it. I have been pretty impressed so far. And I also have used it in a spray bottle like you suggest...I have used it on CV axle boots, rack boots, front end bushings, motor mounts, etc. Even wiper blades! Thanks for hanging out 👍
As per instructions, it needs 5 hours of use as the company representative state it's activated by the hot oil. Also they stated after the 5 hours it does all it can do. They also told me it's a one-time use the way the product penetrates the seal. In other words, they didn't recommend putting it in on every oil change like you read, some people are doing. It'd be interesting if someone else calls them and they get a different tech saying something different.
@@Thatsmessedupman Yes, I've heard of doing it both ways. And if your leak is not very bad, you could probably just do it once, or maybe once every few oil changes. The good news is you can't hurt anything by using it with every oil change if your leak is more on the heavy side and you're trying to slow it down.
@@my-honest-review I'm just passing along what the tech at the company told me. Seeing that in my area, this is $22 a bottle, I figured I'd mention what he told me because some might just be wasting money doing it at every oil change. The way he described it was somehow the product penetrates and expands but once it's done you can't do it again. Whether or not he's correct, I don't know, but since it was the company that I called I figured I'd pass that along.
My 99 Silverado had a terrible rear main seal leak I put this in drove two hours stopped took a look no leak whatsoever. I said wWhat the heck I have Volkswagen type 4 engine the the pushrod tube seals were leaking like a sieve. I put this stuff in ran the engine about a hour leaks completely stopped. This stuff is from another planet
Man I think my 06 silverado has a rear main leak, might gamble with this. Doubt it will harm it, wouldn't think it would get worse if anything. Just only want to have it in for 1 or 2 weeks and do a oil change.
I buy, fix and sell MINI Coopers and unfortunately, as with many European cars, they leak from every single seal. The last two MINIs I bought, after replacing every single seal/gasket I could visually see leaking, I still had minor seapage from the oil filter housing gaskets which are a pain in the behind to replace. I decided to give AT205 a try on the first one and within 3 hours, the leak was completely gone. When I sold the car I told the new owner what I did and even included a new bottle of AT205 in the sale. On the second car it took about 4 days for the leak to be completely gone and I did the same as previously. I told the new owner and even added a bottle in the trunk of the car for their next oil change. This fluid is absolutely phenomenal. I need to get me a new bottle for my weekend car that had both an oil and trans leak.
@@mini_worx Wow, thanks for sharing your experience with AT-205. I have been more and more impressed as time goes on with how well this stuff works. I've never been big on mechanic-in-a-bottle kind of products, but this is certainly that one exception 👍
I emailed them for clarification on their 5 hour statement. Dave replied, 'The 5 hours of run time does not have to be 5 hours continuous, it can be in intervals'. So that's going to checked out tomorrow in my 1997 Toyota Starlet Glanza V 1.3L turbo 4EFTE. I have all the seals to replace on hand. But I'm tired of working on the vehicles during cold and wet weather.
@@BrettSauve That would make sense to me and fall right in line with what I experienced. The results kept getting better with driving time each day. Thanks for sharing!
@@wordnerd2005 It's recommended you add at every oil change. I've found as long as I do this, the seals stay pliable and are restored, therefore continuing to seal. And this will not damage your engine when used correctly.
Rates as best stop leak but not best viscocity or wear. The guy tested it along with several others. AT showed more wear when mixed with motor oil compared to just plain oil. Bardahls actually did the best, but not best at seal softening. AT won that. So not sure what the risk is using AT in a high mileage engine.
@@janpur1417That does make sense, because the surface area on that bell housing is pretty large. Thanks for hanging out and glad the video was helpful👍
i tried it on an old honda civic transmission seemed to slow it down but not stop the leak i think the seals are worn or cracked the at 205 just softens and swells old rubber you should not have to keep adding it after seals are swelled up and stop leaking.
@@ranger178 Very neat, thanks for sharing! I have never tried it on a transmission, but it should work the same way, like you say. It's some pretty good stuff. Not a miracle worker, but if it buys me some time its worth its weight in gold 💯
I dont recommend using it on differentials oil seals. Buddy of mine put it in a not leaking diff and the oil seal started leaking. It might have been from adding too much, being that it's only 1 qt but i dont think he added the whole bottle or anything. I have a feeling that there might be an exponential curve for that measurement. And it might be effected by the weight of the oil and the associated pressure. The engine on the other hand is using lighter oil and the orings or and oil seals are probably not experiencing as much pressure. Especially if you have plugged dif breather tubes.
@@miltechmoto Thanks for that tip, I think you're on to something there about the plugged breather tube. Although I haven't tried it yet on a diff, I would imagine that you'd potentially run into an issue if, like you say, if the gearbox can't breathe. And yes, gotta be careful how much you add with such a small capacity. Thanks for hanging out 👍
@my-honest-review yes the smaller the capacity the more likely you are to add too much. And like I said those types of seals, even brand new diff and axle seals are actually kind hard/stiff rubber from the get go. So I think from the factory the rubber shore hardness is calibrated for a different hardness, it's not just the shape. the engine and transmission oil seals seem just from feeling them, seem to be a bit softer from the get go. Just food for thought. Alternatively maybe he just added too much. But the thing is this product is not supposed to swell seals like other protroleum based conditioners. From the marketing it's supposed to kinda only get to the same softness as when it was new. Not go beyond that.
@RichieMccracken it's honestly best to use before leaks start as when the leaks do occur it can be from cracking of the rubber which cant be fixed by this product but can be prevented by this product. So you have 3 options. Dont put anything and expect leaks within 5 or or 7 years replace seals. Put this in around the 4 year mark and prevent leaks for 10 years. Or wait till it leaks and then put it in, hope it's just hard rubber and not cracked rubber and either it's fixed or it still needs to be replaced.
@@XxGhostR3c0nsxX Great question. Technically 9.3oz of AT-205. So that would be one 8oz bottle plus 1.3oz from another bottle. However if I were you, I'd just stick to one bottle. You could always add a little more later if you don't see the results you're after.
Heres a trick to not have that noise on startup after a pil change Put key in ignition. Jam ur foot all the way down on has peddle. Then crank it. It will default and only crank crank crank no start. Take key back out and put back in and it will b fine
I got a 2020 1500 bighorn that has a leak in the rear axle seal coming from the differential, I would like to know if I can use this product to fix that leak, thanks
@@guillermoandicularios5310 You sure can, it would be perfect for that 👌 You would have to adjust the quantity of AT-205 you use to the capacity of the differential...I am guessing maybe 1/4 of a bottle.
@@my-honest-review thanks for the reply, I will try it for sure, I bought a bottle couple of months ago but didn’t dare to do it. The liquid goes in the engine or do I have to put it where you put the differential oil? Thanks again
@@guillermoandicularios5310 You would just add it to the differential gear oil, and best to do it when you're changing the gear oil out and putting in fresh fluid. And then drive it for a good long ways afterwards. Good luck, hope it helps!
Unfortunately it did not fix my issue with an 05 Maxima. Poured in a bottle after recent oil change and still smell burning oil while driving w window open
You may have a valve cover leak if you are smelling oil. Oil may be leaking out and hitting your exhaust manifold. Generally what I have found is that AT-205 does much better on round rubber seals than larger gaskets like valve cover gaskets. Just speculating in your case..
@@videomaniac108 Technically it thins the oil just a hair, but its not noticeable. And that would make sense being that the AT205 to oil capacity ratio is so small.
Go watch project farms video on engine oil leak products! He tested a lot of these products and the at 205 does breakdown the viscosity some but not enough to hurt the engine
@@robertsimpson7113 That's what I find too, its just old habit. I did have an engine one time where I could tell a difference in the flow of the oil when I loosened the oil cap, but the PCV system was plugged up.
@@Doug_Hefernen Yes, I have found that you get the best results the more the vehicle is driven after adding the AT205, simply because it does tend to separate from the oil when allowed to sit. And that's why it took a few days in the video for my leak to stop..I didn't drive enough initially.
@@FarhatJemai-l1t Indeed the longer you can run your engine after the application, the better the results. And that's why it took a few days before I noticed a big difference in my leak.
While this may slightly help small leaks, it will also seal your oil pump and potentially harm your engine. I might do this on a $1000 car. You might consider cleaning the leaking surface really good with kerosine and applying a small bead of RTV around the leaking area. Probably won't last forever but will help.
@@wordnerd2005 You're probably thinking of traditional sealers. This works differently. It doesn't "plug" anything, just conditions rubber seals making them more pliable. I've been very impressed with it.
Man, don't spoil your operation there by using a FRAM filter! Go with PUROLATOR!!! Also, use Full Synth' high quality engine oil!..."Engines are expensive, oil is relatively cheap!"---Scotty Kilmer Oh, and thanks for the video, old buddy!!!
@Funkydood Glad you liked the video, thanks for hanging out! Nothing wrong with Purolator for sure, just always have had good luck with Fram. When it comes down to it, what is really important is to change your oil and filter frequently, whatever brand you're loyal to.
@@darrens1322 Indeed, I've always used them on both my vehicles...one's 22 years old and has got 167k miles on it, and the other has 330k miles on it. I've had both of them since they were new.
@@JessieGarcia-p6m Yep, doesn't work on all leaks, that's for sure. Before you give up trying make sure you run your engine a long time after application (several hours...maybe add before a road trip). While this stuff isn't cheap, its a heck of alot cheaper to try than replacing the rear main seal. Also, you may be leaking from somewhere you didn't realize, where there is not a rubber seal (this will not help with valve cover gaskets for instance).

@RichieMccracken it's honestly best to use before leaks start as when the leaks do occur it can be from cracking of the rubber which cant be fixed by this product but can be prevented by this product. So you have 3 options. Dont put anything and expect leaks within 5 or or 7 years replace seals. Put this in around the 4 year mark and prevent leaks for 10 years. Or wait till it leaks and then put it in, hope it's just hard rubber and not cracked rubber and either it's fixed or it still needs to be replaced.
What if your truck holds 7 quarts of oil, how much do i need?? Thanks
@@XxGhostR3c0nsxX Great question. Technically 9.3oz of AT-205. So that would be one 8oz bottle plus 1.3oz from another bottle. However if I were you, I'd just stick to one bottle. You could always add a little more later if you don't see the results you're after.
Heres a trick to not have that noise on startup after a pil change
Put key in ignition. Jam ur foot all the way down on has peddle.
Then crank it. It will default and only crank crank crank no start.
Take key back out and put back in and it will b fine
Wow, I appreciate that, I will definitely give that a try, thanks for the tip!
I got a 2020 1500 bighorn that has a leak in the rear axle seal coming from the differential, I would like to know if I can use this product to fix that leak, thanks
@@guillermoandicularios5310 You sure can, it would be perfect for that 👌 You would have to adjust the quantity of AT-205 you use to the capacity of the differential...I am guessing maybe 1/4 of a bottle.
@@my-honest-review thanks for the reply, I will try it for sure, I bought a bottle couple of months ago but didn’t dare to do it. The liquid goes in the engine or do I have to put it where you put the differential oil? Thanks again
@@guillermoandicularios5310 You would just add it to the differential gear oil, and best to do it when you're changing the gear oil out and putting in fresh fluid. And then drive it for a good long ways afterwards. Good luck, hope it helps!
How's it holding up in the last month since you posted this?
@@datsuntoyy I have been very impressed actually. Only a small drip every now and again. Its not 100%, but I would say 90% success!
Unfortunately it did not fix my issue with an 05 Maxima. Poured in a bottle after recent oil change and still smell burning oil while driving w window open
Gonna try some other brands, but this AT-205 stuff is kinda expensive compared to Lucas, etc
You may have a valve cover leak if you are smelling oil. Oil may be leaking out and hitting your exhaust manifold. Generally what I have found is that AT-205 does much better on round rubber seals than larger gaskets like valve cover gaskets. Just speculating in your case..
@my-honest-review yeah I was quoted over 600 bucks for the valve cover job...I declined since car probably not worth much more than that
@tonyyayo2115 I hear ya, yep, just keep a check on the oil level.
I'm curious how it would affect the oil's viscosity.
@@videomaniac108 Technically it thins the oil just a hair, but its not noticeable. And that would make sense being that the AT205 to oil capacity ratio is so small.
Go watch project farms video on engine oil leak products! He tested a lot of these products and the at 205 does breakdown the viscosity some but not enough to hurt the engine
Wow, now i feel safer to add to my 5.3 Silverado engine which either burns oil or leaks it
@@RubyLahna-f6h Indeed, I hope it works for you 🙏
What about high mileage oil with that product
@@derekcampbell9663 It should be just fine if you have been using high mileage oil all along.
I use to be a die hard fram oil filter guy too. After studying on it....stay away from fram.
@@kraigjohnson-dv4dg Thanks for sharing, did you have one event in particular that turned you away?
@@my-honest-review One was that they said the cardbord in the fram was bad.
@@my-honest-review I just put the seal treatment in today. $22 bucks at NAPA we will see
@kraigjohnson-dv4dg Cool deal, keep us posted on how it works!
@@kraigjohnson-dv4dg One of these days I'm going to take the time to cut one of these filters open and do a video on it, I've always wanted to..
The OL engine OL
clean that surface and smack some good silicone on there!
Your oil cap tip is an old wives' tale. There are plenty of places in the engine where air can get in to let your oil flow free!!!
@@robertsimpson7113 That's what I find too, its just old habit. I did have an engine one time where I could tell a difference in the flow of the oil when I loosened the oil cap, but the PCV system was plugged up.
Prefilling the oil filter with oil will probably shorten the time during which you hear valve clatter during the initial startup.
@@videomaniac108 Yes you are so right, I need to start doing that 👍
This product is great but it doesn’t not mix well with oil.
@@Doug_Hefernen Yes, I have found that you get the best results the more the vehicle is driven after adding the AT205, simply because it does tend to separate from the oil when allowed to sit. And that's why it took a few days in the video for my leak to stop..I didn't drive enough initially.
@@my-honest-review I keep mine in a spray bottle to use on rubber weatherstrip, suspension,hoses etc etc.
@@Doug_Hefernen That is also a great use of this stuff 👍 (I even use on wiper blades)
Whole bottle is fine for 5 qts. It's not gonna hurt anything.
@@goatmanilla You're probably right I'm sure.
you have to drive about 500 miles for it to work properly
@@coiamo Definitely the more you drive, up to about 5 hours or so, the better the results.
I heared that it needs 5 hours driving to get good results
@@FarhatJemai-l1t Indeed the longer you can run your engine after the application, the better the results. And that's why it took a few days before I noticed a big difference in my leak.
While this may slightly help small leaks, it will also seal your oil pump and potentially harm your engine. I might do this on a $1000 car. You might consider cleaning the leaking surface really good with kerosine and applying a small bead of RTV around the leaking area. Probably won't last forever but will help.
@@wordnerd2005 You're probably thinking of traditional sealers. This works differently. It doesn't "plug" anything, just conditions rubber seals making them more pliable. I've been very impressed with it.
There is a minimum of 5 hours drive time to be effective.
@@found1thatworks For sure, best results is after a period of driving, and doesn't need to be all at once.
Man, don't spoil your operation there by using a FRAM filter! Go with PUROLATOR!!! Also, use Full Synth' high quality engine oil!..."Engines are expensive, oil is relatively cheap!"---Scotty Kilmer Oh, and thanks for the video, old buddy!!!
@Funkydood Glad you liked the video, thanks for hanging out! Nothing wrong with Purolator for sure, just always have had good luck with Fram. When it comes down to it, what is really important is to change your oil and filter frequently, whatever brand you're loyal to.
Fram😳
@@darrens1322 Indeed, I've always used them on both my vehicles...one's 22 years old and has got 167k miles on it, and the other has 330k miles on it. I've had both of them since they were new.
Did not work for me twice, two different times. A waste of my money. This stuff isn't cheap
@@JessieGarcia-p6m Yep, doesn't work on all leaks, that's for sure. Before you give up trying make sure you run your engine a long time after application (several hours...maybe add before a road trip). While this stuff isn't cheap, its a heck of alot cheaper to try than replacing the rear main seal. Also, you may be leaking from somewhere you didn't realize, where there is not a rubber seal (this will not help with valve cover gaskets for instance).
