ATP Automotive AT-205 Re-Seal Stops Leaks, 8 Ounce Bottle

Okay, where do we begin. I bought my vehicle from a dealer who bought it from an insurance lot. Something has fallen onto the vehicle and crashed the hood and the surrounding areas. But the engine bay was untouched. The vehicle sat at the insurance lot for about 6 months without being started. Once the dealer purchased it he took it to a body shop where they fixed all the body panels the hood etc. Then when they try to sell the vehicle they had a hard time selling it because it was a six-speed manual transmission. So it's sad at the dealership for another 4 months. Now all this sitting and not running caused the rear main seal to dry out. After I purchased the vehicle about 3 months into driving a substantial leak happened at the rear main seal where I was losing about half a quart of oil a week. Took it to the dealership the estimate to fix it was around $3,800. Called a independent mechanic it was about 2800 to $3,000 to fix it. I just did not have that amount of money to throw at it. So I started searching online and stumbled upon AT205.Now before I purchased this product I did my due diligence did the research watched the video of the manufacturer. Educated myself and how is this product different from any other stop leak product. And where I was sold was that this product did not swell the seals but what it did was or what it does is it rejuvenates and restores the elasticity and the plasticity of the seals due to the plasticizers and plastic stabilizers that this product contains. So I bought it.The product arrived quickly, and as quickly as it did arrive I poured it into my engine. I mean what's the worst that can happen, it doesn't work right. I followed the instructions drove the car around for about 30 minutes to let everything mix in. And then it was time to drive and get about 5 hours of driving time. It took about 5 days of commuting back and forth to work to get those 5 hours in. After about 3 hours I noticed when I would stop at a parking spot for extended period of time and I would move my vehicle instead of having 10 drops of oil under the engine I would have three or four. After about 5 to 7 hours of driving The only oil left was the residual oil on the bottom of the engine that I have not wiped off yet because a car is too low to the ground.It's been about 2 weeks now and I have zero drips of oil under my car. Fresh oil that is. At my house in the driveway I still do have the oil spots from the leak that were there before I use this product. As of now there are dried out and everyday I check for new spots and I see any.I'm highly satisfied with this product and what it has done thus far. How is it going to work in the future I don't know. Will the oil leak come back with my next oil change not sure. But what I do know as of right now there's no leak. I'm thinking about buying another bottle and add it with my next oil change just to be sure that those seals get the love that they need to be able to seal the engine properly for a long time to come.One thing I'm going to do is, I will update this review a year from today.If you have a car that has a front main or rear main seal leak or any other leak when your engine try this product out it might just save you hundreds of dollars that you may or may not have.Yes I highly recommend this product to anybody that has a engine leak.

I have to say that it is very rare I would ever use or recommend anything from the "snake oil" section of an auto parts storeThis AT-205 I had researched and felt as comfortable as one can be using any additive.I had purchased a 2006 Ford Explorer with a very minor leak at the rear main seal. I am sure starting with a very minor leak helped too.The vehicle literally looked brand new. It looked like the leather seats had never been used. There was not a single mark on the paint. The motor and transmission worked flawlessly. The only thing I intended to do is replace the plugs with high end Iridiums, the old ones were worn but nothing about their condition otherwise.Its a big job to replace the rear main seal so I decided to give this a try along with a high end oil and filter change then another after a short time to help remove some of the sludge.I added a bottle of this with the second oil change and obviously the seal swelled as intended and there was no more leak.I had a motor that had been well maintained and a very minor leak. Had the leak been worse I suspect this would not have worked as well, fix things fast before they get worse and more expensive.But I was fortunate and this additive was a legitimate product and did what it was designed to do.There is no question this worked in my case and saved me big money if I had needed to replace that sealIf your leak is minor then I have to recommend giving this a try. It is one of the rare items that actually worked as intended.I am very happy with the results.I have watched how spraying this on rubber suspension parts extends their life as they do dry out. Not a bad idea and perhaps save some big amounts of cash.

Tried to return an unopened bottle, but Amazon does not allow it! So be aware. Otherwise, AT-205 works great, but little did I know, you only need to use it once! I ordered it thinking you need to use it with every oil change, but a call to the manufacturer this morning revealed differently. I was told by tech support that once your seals and gaskets absorb the material during one oil change cycle, they won't be able to absorb more on subsequent oil changes. I used this to stop both a rear main seal leak and a timing cover oil leak. It helped completely stop the rear main seal leak (along with a new PCV valve), but the timing cover still seeps a small amount. Along with a slightly higher viscosity oil with this change I'm hoping it will stop leaking all together. Time will tell! Scotty Kilmer of YouTube fame recommended this and he was not wrong, plus I saw a test between this and about nine other stop leak products and AT-205 came out as the pretty clear winner!

Stopped and slowed a couple of weeping seals that were leaking motor oil on a V8 with 210,000 miles. It takes a couple of week before you notice the leaks have stopped but it definitely is worth a try before spending $3000 for a partial teardown of your engine.DO NOT use in your transmission, transfer case, power steering, or any other system. USE ONLY for MOTOR OIL in your engine.
