About this item
  • โœ… PREVENTS AND STOPS ENGINE OIL LEAKS WITHOUT DISASSEMBLY: A powerful formulation designed to effectively stop and prevent engine oil leaks caused by the drying out and shrinking of rubber seals, neoprene rings, and O-rings. This specialised blend penetrates deeply into the affected seals, rejuvenating their structure to restore their original shape and flexibility. The product eliminates the need for costly and time-consuming mechanical repairs by sealing leaks directly within the engine system. Its advanced formula ensures long-lasting protection, preventing further leaks and maintaining engine performance at optimal levels.
  • โœ… RESTORES ELASTICITY OF SEALS AND O-RINGS FOR LONG-LASTING PROTECTION: Formulated with advanced conditioning agents, this product actively restores the elasticity of rubber and neoprene seals, preventing premature wear and deterioration. Over time, engine seals are exposed to extreme temperatures, pressure, and contaminants, causing them to dry out, harden, and shrink, leading to leaks. This solution penetrates deeply into the molecular structure of the seals, revitalising their flexibility and resilience. The result is improved sealing capacity, reduced oil consumption, and prolonged engine life.
  • โœ… LUBRICATES AND PRESERVES ENGINE SEALS FOR OPTIMAL PERFORMANCE: A highly effective lubricant that maintains engine seals in excellent condition by reducing friction and wear. This formula creates a protective layer around rubber and neoprene seals, preventing further cracking, drying, or brittleness due to heat and oxidation. It helps to sustain the integrity of engine components, ensuring smooth operation without interference. Unlike conventional sealants that may harden over time and reduce efficiency, this treatment keeps seals flexible and resilient, allowing them to maintain a secure fit and prevent leaks.
  • โœ… COMPATIBLE WITH ALL MINERAL AND SYNTHETIC ENGINE OILS: Designed for versatility, this oil leak stopper is fully compatible with all types of mineral and synthetic engine oils, making it suitable for a broad range of applications. Whether used in traditional or modern low SAPS (Sulphated Ash, Phosphorus, and Sulphur) applications, it seamlessly integrates into the existing lubrication system without causing adverse effects. Its carefully balanced formula ensures it does not alter the viscosity or chemical properties of the engine oil, allowing the engine to continue running smoothly without any risk of contamination or efficiency loss.
  • โœ… SAFE FOR ENGINES AND CATALYTIC CONVERTERS WITH NO IMPACT ON OIL PERFORMANCE: Unlike traditional oil treatments that can alter viscosity and potentially impact engine efficiency, this product preserves the original characteristics of the oil, ensuring optimal lubrication and heat management. Additionally, it is completely safe for modern engines equipped with catalytic converters, preventing any risk of contamination or damage to exhaust treatment systems. By offering a safe and effective solution for sealing oil leaks, this formulation provides peace of mind for engine maintenance while keeping the vehicle running efficiently and cleanly.
Product 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.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
