Bar's Leaks 1334 One Seal Stop Leak - 11 oz

This seemed to slow the leak in an older Kia Sportage and it was a decent leak. Did not stop it completely but it did help. I think the seals need replacement. But it definitely slowed it which works for now!

I've used this stuff in 2 different vehicles with small oil leaks and it worked.

Works as expected. I use it as a preventive measure in high mileage transmissions that is not yet leaking. I use it to keep the soft seals pliable before they leak. Automatic transmissions have many soft seals internally that are subject to leaking and yet will not leave an ATF puddle on the ground. Caught early enough a leaking external seal can be helped with this stuff. It will not "cure" any internal hard seals that may be leaking.

Excellent

Ok…if you’re reading this then you’ve already searched the internet on whether or not this stuff is safe and/or if it works. As a mechanic, I generally like to take things apart and fix them properly but I have had such good luck with other Bars Leak products (Bars Leak radiator fix is truly amazing stuff )that I decided to give this a try. My issue was this. I had a zero turn mower that uses 20w50 full synthetic motor oil in its hydro’s. Most zero turns use a heavy viscosity motor oil which is why I went with the oil additive vs the hydraulic additive which Bars Leak also makes. Anyway, I had a hydro motor leaking ever so slightly. It would’ve been a huge job to take out and apart and I was pretty sure it was the same problem I’d had on another unit…a leaking o-ring on the low pressure side of the pump. Since this stuff softens the seals/o-rings and causes them to expand I figured it was perfect for the job. Well, it was. I put a little bit in the mowers reservoir and then mowed with it for about 45 minutes. I parked the machine on a piece of construction paper to let me know if I needed to add more or if the product failed. The next morning I came out annnnnnnnd……not a drop! It worked. For the price, this product is hard to beat. It’s inexpensive, easy to use and protects me from inadvertently running out of hydro oil.

“I tried Bar’s Leaks hoping it would fix a small coolant leak, but it didn’t work at all. The leak kept coming back after just a few days, and it even left residue in the system. It felt more like a temporary band-aid than a real solution. Honestly, I wouldn’t recommend it — better to fix the problem properly instead of relying on this product.”

Did not seem to do much definitely did not stol the leak, maybe slowed a bit?

I had a terrible power steering fluid leak, that my mechanic couldn't track down. I tried gallons of the Valvoline stop leak which did nothing. I tried a lot of the Lucas oil stop leak but all that did was make it leak more. Three bottles of this little stuff and I don't see a leak anymore.

يعمل بشكل جيد بعد صبه في محرك السيارة مع زيت جديد بدأت الاحظ بعد اسبوعين توقف التسرب من عدة اماكن كان بها تسريب وقل استهلاك الزيت بشكل ملحوظ جدا

Product does not function even on minor leaks that other brands working.
