Legal Disclaimer U.K MAINLAND SHIPPING ONLY Review: A good additive - This works really well on older cars where you may have a small oil drip here and there. Also quietens the engine. A good proven product Review: Brilliant. - Had a very small oil leak from a Valve Cover on a BMW, that just would not seal at all no matter what, even after gasket replacement. Gave this a try and within 20 miles no leak, no burning oil smell and no drips onto the Manifold. Was very surprised as most of these products never work, but this did. Great product, would use agin. ## Features - Extends the life of engine oil by at least 50% - Contains nothing that could be harmful to an engine - Less engine noise ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002U5XPLO | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | 3,059 in Automotive ( See Top 100 in Automotive ) 15 in Engine Oil Additives | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Compatible with Vehicle Type | Car | | Container Type | [IN] Bottle | | Country Of Origin | United Kingdom | | Customer Reviews | 4.3 out of 5 stars 5,907 Reviews | | Global Trade Identification Number | 00049807102791 | | Included Components | 1 x Lucas Oil Engine Stop Leak - 3.78 L | | Item Type Name | Engine Stop Leak - 3.78L | | Item Weight | 3.56 Kilograms | | Liquid Volume | 1 Gallons | | Liquid volume | 1 Gallons | | Manufacturer | Lucas Oil Products Inc | | Manufacturer Part Number | 10279 | | Manufacturer Warranty Description | No Warranty | | Package information | [IN] Bottle | | UPC | 049807402792 | | Unit Count | 3785.0 millilitre(s) | | Vehicle service type | Car | ## Product Details - **Brand:** Lucas Oil - **Liquid volume:** 1 Gallons - **Package information:** [IN] Bottle - **UPC:** 049807402792 - **Vehicle service type:** Car ## Images ![10279 Gallon Engine Stop Leak, 3.785 Litre - Image 1](https://m.media-amazon.com/images/I/61bGbr6WkfL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this still work if added to existing oil or must it be added at the next oil change?** A: I have used this a number of times in older motorcycles, with great success. I have used it coincident to an oil change and also added it between changes. In both cases it has worked very well, indeed. I should not hesitate to add it without changing the oil, provided that there is room for it within the oil capacity of the machine. **Q: Will this work on a main seal for a beetle with an air cooled engine which uses mineral oil and only holds 2.5 litres of oil.** A: Depends on how badly the seal is worn, if just allowing a small amount of oil to pass and small amount of smoke then could help, if seal is damaged and need replacing then it wont help..certainly worth a try if just smoking slightly... **Q: Will this work to seal piston rings on a Zafira please** A: Sorry no.Only works on oil seals. **Q: i think my turbo leaking oil on my tt will it work on it.** A: I am confident it might. .

A good proven product ### ⭐⭐⭐⭐⭐ Brilliant. *by A***N on 3 July 2025* Had a very small oil leak from a Valve Cover on a BMW, that just would not seal at all no matter what, even after gasket replacement.

Great product, would use agin. ### ⭐⭐⭐⭐ Another Lucas product in my bag of tricks ... *by N***L on 24 January 2020* After 300k miles, the car has a suspect oil leak (probably the turbo bearing seals) and to make matters worse, on a recent oil change I put in a slightly thinner grade of oil than I should. Used various Lucas products in the past (the fuel saver is really good, as is the oil stabiliser) and decided to get a bottle of stop leak and add a little to thicken the oil. Slight engine rattle disappeared immediately. If there is a persistent slight oil leak, given my experience with other lucas products - I have the utmost confidence that it will slow it down as I add more when and if there's room to. ## Frequently Bought Together - Lucas Oil 10279 Engine Oil Stop Leak - 1 Gallon - Lucas LUC10013 10013 Fuel Treatment - 1 Gallon - Lucas Oil 10002 Heavy Duty Oil Stabilizer - 1 Gallon --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/49988113-10279-gallon-engine-stop-leak-3-785-litre](https://www.desertcart.hr/products/49988113-10279-gallon-engine-stop-leak-3-785-litre) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
