About this item
  • โœ… EFFECTIVE SEAL REVITALISATION: Formulated to target and restore the integrity of worn-out rubber and neoprene seals, this oil additive is designed to combat oil leaks by reconditioning seals within the engine system. It penetrates the seals of the crankshaft, camshaft, and valve stems, bringing back their elasticity and flexibility, which are often lost due to prolonged exposure to heat and pressure. This revitalising action helps prevent future leaks by creating a tighter and more reliable seal, effectively reducing oil loss and minimising contamination of surrounding engine parts.
  • โœ… NO DISMANTLING REQUIRED: This engine oil stop leak solution offers a non-invasive approach to resolving oil leak issues. By simply adding it to the engine oil, the product works while the engine runs, eliminating the need for expensive and time-consuming dismantling of engine parts. It addresses leaks from within, flowing seamlessly through the oil system and targeting compromised areas without the need for mechanical intervention. It is especially useful in older vehicles or stationary engines where wear and tear is common, and it serves as a reliable preventive measure to avoid future complications.
  • โœ… COMPATIBLE WITH ALL OIL TYPES: This supplement blends effortlessly with all mineral, synthetic, single-grade, and multigrade oils, making it suitable for a wide range of vehicles and equipment. It is also compatible with both regular and low SAPS (sulphated ash, phosphorus, and sulphur) formulations, ensuring versatility across different engine types and compliance with various emission standards. Whether used in petrol or diesel engines, with or without turbochargers, or even in stationary equipment, this product integrates smoothly without requiring changes to the oil in use.
  • โœ… SAFE FOR CATALYTIC CONVERTERS AND ENGINE COMPONENTS: Specially engineered to deliver leak-stopping performance without compromising the health of the engine or exhaust system, this oil additive does not affect catalytic converters. Free from harmful substances, it maintains the original characteristics of the engine oil and does not alter its viscosity. It supports cleaner engine operation and contributes to a reduction in oil consumption and emissions by sealing leaks efficiently. The formulation is non-corrosive and gentle on engine internals, ensuring long-term reliability and safety across multiple applications, including high-performance and older engines.
  • โœ… RECOMMENDED FOR A WIDE RANGE OF APPLICATIONS: Developed for universal use, this engine oil stop leak is ideal for both petrol and diesel engines, including those equipped with turbochargers. It is suitable for cars, trucks, agricultural machinery, and stationary equipment experiencing oil loss or seal degradation. Whether for regular maintenance or as a corrective measure, it addresses oil leak concerns without altering the oil systemโ€™s functionality. This makes it a valuable solution for fleet operators, mechanics, and those managing industrial engines, as it ensures operational reliability, reduces oil consumption, and prevents premature wear caused by leaking oil.
Product 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 โ€” such as those on the crankshaft, camshaft, and valve stems โ€” 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.

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.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
