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!
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.
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
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 👍
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!
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.
@@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👍
@@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.
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.
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 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!
@@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.
@@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.
@@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.
@@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).

You can also try one of the newer "high mileage" motor oils which have increased ester content to help soften seals.

Will it work on gaskets that just use RTV sealent without a rubber gasket?
