  • โœ… IMPROVES THE VISCOSITY INDEX AND STRENGTHENS OIL FILM: Enhancing the viscosity index of lubricating oils is essential to ensure consistent engine performance under varying temperatures. This formulation effectively stabilises the oilโ€™s viscosity, allowing it to maintain its protective properties even under extreme heat or heavy load conditions. By strengthening the oil film, it creates a durable barrier between moving parts, reducing friction and wear. The ability to retain its viscosity under high-temperature, high-shear environments ensures optimal lubrication, prolonging the life of the engine components.
  • โœ… RESTORES COMPRESSION AND OIL PRESSURE FOR OPTIMAL PERFORMANCE: Over time, engine wear can lead to reduced compression and lower oil pressure, causing inefficiencies and potential damage. This formulation is designed to restore lost compression, helping to maintain the power and efficiency of the engine. By improving oil pressure, it ensures proper circulation of lubricating oil, reducing internal friction and preventing dry starts. This is particularly beneficial for engines that experience increased oil consumption, as it helps maintain stability and efficiency.

  • 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… REDUCES EXHAUST SMOKE CAUSED BY OIL BURNING: Specially formulated to address the issue of excessive exhaust smoke, this oil-soluble additive helps reduce smoke emissions caused by oil burning. It works effectively within the engine to stabilise oil consumption, particularly in older or high-mileage engines, where internal components may be worn or degraded. The additive enhances the oil's behaviour under combustion conditions, allowing it to resist being drawn into the combustion chamber. This results in visibly reduced smoke output, making it ideal for improving emissions control and keeping exhaust systems cleaner for longer periods.
  • โœ… IMPROVES OIL VISCOSITY AT HIGH TEMPERATURES: The formula is designed to enhance the thermal stability of engine oil, particularly at elevated temperatures that can thin out the oil and reduce its protective capabilities. By reinforcing the viscosity index, the additive ensures that the oil maintains its thickness and protective film even under demanding engine conditions. This not only prolongs engine life but also ensures optimal lubrication of all moving parts during high-performance or heavy-duty operations. The product is especially valuable in maintaining engine health during summer driving, long-distance travel, or when towing heavy loads.
