Review: IT WORKS. AND IT WORKS GREAT. AS DESCRIBED - 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.
Review: Absolutely Amaxing product! Stopped ALL my oil leaks!s - WOW!! ABSOLUTELY AMAZING!! I never write reviews but felt I needed to for this product. For years I've had oil leaks in my 2005 GMC truck and tried multiple products to try to stop it to no avail. It's gotten to the point where I had 3 or 4 different leaks in various areas. I would park at a store for 10 minutes and come out with several oil droplets on the ground. It was embarrassing. Mechanic said in the areas it was would be very expensive to repair. Tried this product with lil expectations cause nothing else worked. The result was simply amazing!! Zero and I mean zero leaks after using this product!! I can't believe it!! Now if it lasts is the next question but couldn't be happier at this point. Great product!!

## Questions & Answers

**Q: Do I just dump the whole bottle in?**
A: 8oz bottle will treat a 6 quart capacity, adjust accordingly

**Q: Will this work in Chevy 4L60E transmissions**
A: I was reluctant to put it in my 4L60E, but I did when the leak got pretty bad and I didn't have time to fix it. I only put in 1 bottle when the instructions called for 2, but oh my goodness what a result. Stopped the leak completely in under a half hour. I was blown away... blown away. Thought it was snake oil, turns out this stuff is legit. Then as if that weren't enough... the darn transmission started shifting more crisply... tooootally unexpected side benefit. It has lasted almost exactly a year and now the leak is slowly starting to come back. I have no reservations about treating it again. Since it can't over-swell the seals, this time I'll be adding the recommended 2 bottles. This product is a rare diamond in the rough of snake oil products. So to answer your question, yes, apparently it does work in 4L60E transmissions.

**Q: So basically I just put this where I would put the oil and it should stop the leak? Thanks**
A: I have used it on an Audi A6 2014 with supercharged 3.0T 109K miles. There was a really small leak that I could not figure out where it came from (back side of engine, it was not the timing chain covers, maybe the oil filter housing). Anyway, after putting this and driving about 300 miles later it seemed to stop the leak for a few months. Later sold the car for other reasons but I am happy with what this did. It rejuvenated the seals.

**Q: Is it necessary to drive the 5 hours at once, or does this refer to intermittent driving?  Thanks!**
A: It can be intermittent, Just need a total of about 5 hours, made up of multiple outings.  Best to start vehicle (and run at least a few minutes) as soon as possible after adding AT-205 so that it is evenly mixed with the oil.

### ⭐⭐⭐⭐⭐ THANKS AMAZON!! "NO SNAKE OIL" ..BEST $10 EVER SPENT (CAN SAVE ON COSTLY REPAIRS) & reviewers please read.
*by J***8 on April 8, 2016*

Worked Great!!! I used this in my 2003 Ford Ranger 4.0L. Old Engine broke a timing chain and ruined the engine (162,000 Miles) . Upon Mechanics advise I replaced the engine with a used engine of 88,000 miles. "No telling how long the engine spent setting, and I am positive now that all of the gaskets were dried out ". After install, I noticed a slow leak showing up. When I asked my mechanic about adding any Engine stop leak he immediately "No". Drive as much as possible and let the oils heat up and saturate any gaskets and see if it stops. No Burning Smoke, Not loosing any coolant, so I went online searching for info and came across this ATP. I Trouble shot a lot of options and figured it might be the Rear Main Seal, but just not sure. Researched options and came across This Stuff!. Not like some of the other additives that can clog other part and cause more problems, I figured for around $10 why not try. Glad I Did! As the Directions State to add the correct amount to your oil (Mine came out to 6.6 oz from the 8oz bottle for a 5qt oil). Drove to town and around letting the Engine get to, and run at normal heat for at least 45 min. before making my first stop. A few more start & stops and then the trip home. Parked the truck on the concrete pad with oil dry covering any old leak spots. Parked the truck over night and WALLAH!! the next morning.. No new leak spot! This stuff is thin and not thick like other brands sold at Auto Parts Stores, So I am confident it rejuvenated and swelled any rubber type seals in my engine without clogging or plugging like other brands. I plan on even changing the oil to confirm it has completely worked. I am very confident it has. I HIGHLY RECOMMEND this ATP Product for any suspicious slow leaks that may come from any Rubber Gaskets. Do your research, but this was the best $10 I ever spent and Shipping was faster that originally stated. Original tracking stated 4-10 Business days. I received mine in 3 days. I will defiantly buy again to have on hand for any future needs. Has a lot of use potential. I hope any future users have the same results if Gaskets are not totally blown out! As stated on the product description. Good Luck! It's worth the $10 vs costly tear down and gasket replacement. ATP AT-205 Re-Seal Stops Leaks, 8 Ounce Bottle PS..This is not currently found in any Auto Parts Stores. THANK YOU AMAZON!! I showed the bottle to one of my ASE Mechanic buddy's who is a store manager @ an O'riley's and he had never seen or heard of this stuff. Blue Devil, yes.., but not this. Thanks Jerry31368
