Compatible with all engine oils and fuel types, it penetrates and revitalizes seals without altering oil viscosity or requiring engine disassembly. This product protects engine components, reduces oil consumption, and extends engine life, making it an essential maintenance solution for vehicles and machinery. ## Description This advanced oil leak stopper is a high-performance solution designed to prevent and stop engine oil leaks caused by the deterioration of rubber and neoprene seals. Over time, exposure to extreme temperatures, pressure, and engine contaminants can cause seals to dry out, shrink, and crack, leading to oil leaks that affect engine efficiency. This product effectively restores the flexibility and elasticity of seals and O-rings, reinforcing their structure to prevent further damage. Thanks to its specially formulated blend of conditioning agents, this treatment deeply penetrates the seals, rehydrating and revitalising them to restore their original shape and sealing capacity. By eliminating oil leaks at the source, this solution reduces oil consumption, protects engine components, and ensures a clean and efficient operation. Its unique formulation allows it to work without requiring engine disassembly, offering a fast and convenient way to address common sealing issues. Unlike other oil additives, this leak stopper does not alter the viscosity or chemical composition of engine oil. It remains fully compatible with all mineral and synthetic engine oils, including low SAPS applications, ensuring optimal performance without any negative impact. Additionally, it is safe for use in all petrol, LPG, and diesel engines, making it a versatile choice for various vehicle types and industrial machinery. Beyond sealing leaks, this product also acts as a protective lubricant, maintaining engine seals in excellent condition. By creating a barrier against heat, oxidation, and wear, it helps extend the lifespan of engine components while preserving efficiency. Safe for catalytic converters and emission control systems, it offers a reliable and effective solution to maintaining engine health. Ideal for vehicles and equipment requiring a leak-stopping solution without complex repairs, this product is an essential addition to any maintenance routine. Whether preventing potential oil leaks or addressing existing issues, this powerful formula ensures engines remain protected, efficient, and free from unwanted oil drips. Review: It's a can of engine stop leak :-) - Good price. Poured into car and now have to drive 300km to see if it's worked. Will be back to update after 300km completed.

Hope this is helpful. **Q: do you just put it in engine and thats it or do you need to drain oil first** A: Just add to engine as if topping up oil -- follow instructions on can. It made a significant difference to my engine. If your engine is due for a routine oil change then do this first and add Stop Leak with new oil. **Q: Will it stop oil coming out of the manifold on a Nuffield tractor?** A: It's really designed to soften old seals that have become stiff and letting oil pass, it doesn't stop oil leaking from splits etc **Q: can this be sprayed directly onto rubber parts?** A: I apply it once a year on all rubber in suspension and joints behind the wheel area. Simply pour it into a spray bottle and spray on those parts generously. It well protects them and last them longer. Just a few weeks ago I used on my sister's 2003 Ibiza who was annoyingly making squeaky noise on the right suspension area, now it is gone. A tin would be more than enough for your car all over. I got this idea from a car mechanic in this business for over 50 years. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's a can of engine stop leak :-) *by P***E on 3 July 2026* Good price.
