Compatible with all oil types and engine models, it protects catalytic converters and maintains oil quality, making it an efficient, eco-friendly, and cost-effective solution for extending engine life and reliability. ## Description This oil-soluble engine additive has been specially designed to stop and prevent oil leaks by reconditioning internal engine seals. It works internally without requiring disassembly of the engine, making it an efficient and cost-effective solution for oil leak problems. The formula penetrates worn rubber and neoprene seals — such as those on the crankshaft, camshaft, and valve stems — restoring their flexibility and preventing further degradation. The product is compatible with all types of engine oils, including mineral, synthetic, single-grade, and multigrade oils, and is suitable for both regular and low SAPS applications. Its use does not compromise the catalytic converter, nor does it influence the quality or viscosity of the oil. Whether used in petrol or diesel engines, with or without turbochargers, or in stationary equipment, this supplement provides a simple and effective solution to oil leaks. It supports engine cleanliness, reduces emissions by preventing oil burning, and enhances long-term engine reliability. Particularly beneficial in aging engines, it offers a preventive and corrective approach to oil loss, extending the service life of seals and reducing the need for expensive mechanical repairs. Review: Not an instant cure but does work - I took a chance using this as I didn’t have the money or the time to investigate the oil leak before the mot retest date. All I can say, is that for me the product has worked. It needs time and miles and the engine to be at normal operating temperature to work better but it has stopped the leak. But it isn’t a miracle cure. I still check the engine oil level and I will get the leak looked at but this has given me some breathing space so I think it’s worth it. Review: Less leaks than a government department - I was not overly hopefully when purchasing that this would do the job. Having tried Wynns standard version a while ago for a small leak I was left disappointed. However I thought the professional version might do better as a temporary fix until I isolated the source. Well it worked far better than expected and in line with other online reviews. So my faith was restored in Wynns. I'm sure there are better products on the market but at this price point you have a good solution for your car and pocket. (Though I doubt any additive will stem a huge leak, so be reasonable in your expectations). ## Features - Value for money - Safely packed - High quality - Range always up-to-date - One-stop-shop ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001NUOJYY | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | 64,706 in Automotive ( See Top 100 in Automotive ) 80 in Engine Oil Additives | | Brand | Wynn's | | Brand Name | Wynn's | | Compatible with Vehicle Type | Car | | Container Type | Tin | | Customer Reviews | 4.3 out of 5 stars 663 Reviews | | Flash Point | 170 Degrees Celsius | | Flash point | 170 Degrees Celsius | | Global Trade Identification Number | 05411693774416 | | Item Type Name | Wynn'S 1831027 77441 Engine Oil Stop Leak | | Item Weight | 300 Grams | | Liquid Volume | 325 Millilitres | | Liquid volume | 325 Millilitres | | Manufacturer | Wynn Oil UK | | Manufacturer Part Number | WYN77441 | | Manufacturer Warranty Description | 1 Year | | Model Number | 1831027 | | Number of Packs | 1 | | Package information | Tin | | SAE J300 Viscosity Grade | 10W-30 | | Size | 325 milliliters | | Unit Count | 325.0 millilitre | | Vehicle service type | Car | ## Product Details - **Viscosity:** 10W-30 sae_grade - **Brand:** Wynn's - **Vehicle service type:** Car - **Automotive Fit Type:** Universal Fit - **Global Trade Identification Number:** 05411693774416 ## Images ![Wynn's Pro Engine Oil Stop Leak - Restores Seal Flexibility & Prevents Oil Leaks Without Dismantling - Safe for Catalytic Converters - Compatible with All Oils & Engine Types - 325ml - Image 1](https://m.media-amazon.com/images/I/61y4AeADgOL.jpg) ![Wynn's Pro Engine Oil Stop Leak - Restores Seal Flexibility & Prevents Oil Leaks Without Dismantling - Safe for Catalytic Converters - Compatible with All Oils & Engine Types - 325ml - Image 2](https://m.media-amazon.com/images/I/81-CCfZq-KL.jpg) ![Wynn's Pro Engine Oil Stop Leak - Restores Seal Flexibility & Prevents Oil Leaks Without Dismantling - Safe for Catalytic Converters - Compatible with All Oils & Engine Types - 325ml - Image 3](https://m.media-amazon.com/images/I/71Fu69SznqL.jpg) ![Wynn's Pro Engine Oil Stop Leak - Restores Seal Flexibility & Prevents Oil Leaks Without Dismantling - Safe for Catalytic Converters - Compatible with All Oils & Engine Types - 325ml - Image 4](https://m.media-amazon.com/images/I/71Vc+0Dre0L.jpg) ## Questions & Answers **Q: Will this help with oil pressure low warning on a vauxhall insignia** A: Possibly! Vauxhall oil pressure switches were always a common failure. If the switch is faulty, nothing in a tin will fix it... If the pressure is low due to engine wear, this is worth a try! **Q: Can use with standard stop leak ???** A: Hi, no, I wouldn't advise mixing additives, especially stop leak ones. They work by thickening the oil, so two lots of additive might make the oil way too thick to protect the engine. **Q: have an oil leak coming from timing cover , on v w lt 35 diesal 2.5 , is this suitable to stop leak** A: Not stopped mine **Q: Hi.. is this an actual Wynns Professional product as shown in the listing?** A: Hi Yes the product shown on the website is the product that you will receive. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not an instant cure but does work *by R***E on 19 August 2025* I took a chance using this as I didn’t have the money or the time to investigate the oil leak before the mot retest date.
