Did not stop it completely but it did help. I think the seals need replacement. But it definitely slowed it which works for now! ### ⭐⭐⭐⭐⭐ It works *by J***Y on April 3, 2026* I've used this stuff in 2 different vehicles with small oil leaks and it worked. ### ⭐⭐⭐⭐ Not a 'cure-all' *by R***5 on September 20, 2026* 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. ## Frequently Bought Together - Bar's Leaks 1334 One Seal Stop Leak - 11 oz - Bar's Leaks Rear Main Seal Repair, 16.9 oz - Bar's Leaks OS-1 Oil Seal Engine Oil Burning and Leak Repair, 16.9 oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/584988465-1334-one-seal-stop-leak-11-oz](https://www.desertcart.co.uk/products/584988465-1334-one-seal-stop-leak-11-oz) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-20*
