Wynn's Super Charge Oil Treatment - Enhances Viscosity - Restores Compression & Pressure - Reduces Oil Consumption & Smoke Emissions - Prevents Metal Contact & Engine Wear - 425ml

9.9 worth the money

9.9 distance

9.9 Simple to use

Why we love it

Boosts engine performance and longevity.

Reduces oil consumption significantly.

Ideal for older engines with high wear.
Main highlights

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.
REDUCES EXCESSIVE OIL CONSUMPTION AND MINIMISES SMOKE EMISSIONS: Excessive oil consumption is a common issue in older engines or those subjected to high levels of stress. This specially formulated additive reduces the rate at which oil is burned, leading to lower oil consumption and fewer top-ups between oil changes. Additionally, it helps minimise the formation of exhaust smoke caused by oil burning, resulting in cleaner emissions. Reducing smoke output not only benefits the environment but also enhances the overall efficiency of the engine.
QUIETENS NOISY ENGINES AND PROTECTS AGAINST CORROSION AND WEAR: Engine noise is often a result of insufficient lubrication and increased friction between moving parts. This advanced formulation reduces mechanical noise by ensuring that all engine components are adequately lubricated, leading to smoother and quieter operation. Additionally, it offers strong protection against corrosion, oxidation, rust, and wear, shielding the engine from harmful contaminants and moisture. By forming a protective layer on metal surfaces, it prevents rust formation and oxidation, preserving engine performance over time.
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 oil’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.
ENSURES SOLID LUBRICATING FILM AND PREVENTS METAL-TO-METAL CONTACT: Maintaining a strong lubricating film is crucial to protect the engine’s moving components from wear and damage. This treatment ensures a solid oil barrier that remains effective even under high load and extreme temperatures. By reducing direct metal-to-metal contact, it prevents surface degradation, friction-induced heat buildup, and premature part failure. The reinforced oil film provides superior lubrication across all critical engine components, minimising the risks of mechanical breakdown.
