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. Review: Great product as always from Bars Leak - 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. ## Features - Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F13298X | | Best Sellers Rank | #21,065 in Automotive ( See Top 100 in Automotive ) #158 in Engine & Oil Fluid Additives | | Brand | Bar's Leaks | | Brand Name | Bar's Leaks | | Color | No color | | Compatible Material | Metal, Plastic, Rubber | | Customer Reviews | 4.4 out of 5 stars 300 Reviews | | Global Trade Identification Number | 50046087013347 | | Included Components | Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) | | Item Dimensions | 6.5 x 3 x 1.8 inches | | Item Form | Liquid | | Item Type Name | Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) | | Item Weight | 11 ounces | | Item dimensions L x W x H | 6.5 x 3 x 1.8 inches | | Manufacturer | Bar's Leaks | | Material | Plastic | | Material Type | Plastic | | Model | 1334-5PK | | Number of Items | 5 | | Part Number | 1334-5PK | | Style | Automotive | | Style Name | Automotive | | Surface Recommendation | Miscellaneous | | UPC | 046087013342 | | Unit Count | 55 Fluid Ounces | | Warranty Description | Warranty | ## Product Details - **Brand:** Bar's Leaks - **Item Weight:** 11 ounces - **Item dimensions L x W x H:** 6.5 x 3 x 1.8 inches - **Material:** Plastic - **Style:** Automotive ## Images ![Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) - Image 1](https://m.media-amazon.com/images/I/718pdgjynwL.jpg) ![Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) - Image 2](https://m.media-amazon.com/images/I/71wFVyJCOmL.jpg) ![Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) - Image 3](https://m.media-amazon.com/images/I/818jJET6ZoL.jpg) ![Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) - Image 4](https://m.media-amazon.com/images/I/71EuBreOAAL.jpg) ![Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) - Image 5](https://m.media-amazon.com/images/I/81j65e2Vr9L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How is this product used?** A: Thank you for your question, and for considering Bar's Leaks to help with your automotive needs.

It helped most of the vehicles and reduced the oil leaks. It did not stop them but it did noticably reduce the oil leaks at least 50% so it's worth it. ## Frequently Bought Together - Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5) - 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.gr/products/85430261-bars-leaks-1334-5pk-one-seal-stop-leak-11-oz](https://www.desertcart.gr/products/85430261-bars-leaks-1334-5pk-one-seal-stop-leak-11-oz) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-23*
