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. . Sealed my oil leak ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by R***. on 28 September 2025* Did exactly what it said it would, cured an oil leak on a combine. ### ⭐⭐⭐⭐⭐ Did the job well. *by H***M on 16 April 2026* Very effectively stopped a worn engine from consuming lots of oil. Very happy. ### ⭐⭐⭐⭐ Better than expected *by N***E on 26 August 2021* I was expecting very little from an "magic oil stop leak" product but it's actually not terrible. The bottle itself looks terrible and the instructions are....... ropey at best but it does genueinely seem to have reduced my oil burning. My valve seals have been letting oil past ever since I got my car but they are letting noticibly less oil though now. It's not a miricle fix, but it has made a difference, so for £15 I am happy to recommend this. ## 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? - 🛒 **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.fr/products/49988113-lucas-oil-10279-gallon-engine-stop-leak-3-785-litre](https://www.desertcart.fr/products/49988113-lucas-oil-10279-gallon-engine-stop-leak-3-785-litre) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-21*
