Rislone 4405 – ZDDP Zinc Additive for Engine Wear, 325ml

Product Description

The Rislone 4405 ZDDP Zinc Additive is a premium USA-formulated engine wear protection additive, available in India exclusively via naredi. It replenishes depleted ZDDP (zinc) levels in modern oils, protecting camshafts and valve trains in older petrol and diesel engines. Ideal for classic Ambassadors, vintage Royal Enfield Bullets, and old Mahindra Jeeps battling India's extreme heat and punishing stop-go traffic.

Features & Benefits

• Anti-Wear Film: Forms a tenacious ZDDP layer on camshafts and lifters, preventing costly metal-to-metal contact.
• Restores Zinc Levels: Compensates for low ZDDP in modern oils that older engines were never designed for.
• Extreme Heat Resistance: Stays effective when Indian summers push under-bonnet temps beyond 50°C.
• Friction Reduction: Lowers operating friction for better throttle response and longer engine life.
• Universal Oil Compatibility: Works with mineral, semi-synthetic, and synthetic oils.
• Pre-Measured Dose: 325ml treats standard sump volumes — no guesswork, no over-treating.
• Cost Prevention: Avoids expensive camshaft and lifter rebuilds on vintage, irreplaceable engines.

Understanding the Technology

ZDDP (Zinc Dialkyldithiophosphate) is a boundary-lubrication compound that bonds chemically to metal surfaces under high pressure, forming a sacrificial tribofilm that absorbs wear instead of your engine components. Modern API SN/SP-rated oils carry reduced ZDDP to protect catalytic converters — a trade-off that leaves flat-tappet and high-lift camshaft engines dangerously under-protected. The best ZDDP oil additive supplements replenish this deficit without altering base oil viscosity, making them essential for classic and vintage engine longevity in India's high-temperature operating environment.
