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.

So far AT 205 has done a great job.

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.

[@philm2603]

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!

[@JohnEngel]

That’s awesome. I would’ve never thought about this for valve seals but that’s a great idea and so glad that it worked.

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

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]

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.

[@denniswhite4446]

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.

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.

@@qssneaky Thanks. I've a 04 4.7 leakin like a siv. Been dreading tranny removal. I bet I've got 3, maybe 4 new seals floating around here. Seem like no matter how many I buy, I can't find the one that self installs🤣

[@qssneaky]

@@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.

[@infodotwtf]

What if you don't drive right away after putting it in?

Kiwi Wewi just the one.

[@MEGAPARTY140]

@@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!

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.

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.

[@VIZCANO]

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

[@JohnEngel]

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.

Unfortunately, from my experience, every oil change will require a new bottle to be added.

[@vladimir0700]

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?

[@JohnEngel]
