HBN Decore SAE 10W-40 Fully Synthetic Engine Oil

HBN Decore 10W40 Fully Synthetic Car Engine Oil is an advanced, high-performance fully synthetic lubricant engineered specifically for modern passenger cars and multi-valve petrol and diesel engines operating under rigorous Indian road and weather conditions. Formulated with premium synthetic base stocks, shear-stable viscosity modifiers, and advanced ZDDP anti-wear chemistry, this decore 10w40 fully synthetic engine oil provides robust boundary lubrication, superior micro-pitting resistance, minimizes frictional drag, and ensures a consistent hydrodynamic oil film thickness under extreme thermal stress.

Fully compliant with BS6 emission standards and engineered to meet API SN/CI-4 specifications, it delivers dependable thermal oxidation stability, smoother throttle response, reduced engine NVH (noise, vibration, and harshness), and extended component life across highway cruising and severe stop-and-go city traffic.

Features

✔️ 100% Fully Synthetic Technology: Formulated with high-purity synthetic base oils for maximum thermal stability

✔️ SAE 10W-40 High Viscosity Index: Guarantees rapid cold-start oil flow and stable high-temperature film strength

✔️ API SN / CI-4 Dual Performance: Dual-certified for high-revving petrol cars and high-torque passenger diesel engines

✔️ BS6 Compliant: Low-volatility chemistry engineered to protect catalytic converters and exhaust aftertreatment devices

✔️ Advanced ZDDP Anti-Wear Protection: Forms a sacrificial tribofilm across cam lobes, bearings, and cylinder walls

✔️ Multi-Fuel Compatibility: Optimized for naturally aspirated, turbocharged, and supercharged petrol, diesel, and CNG engines

✔️ High Shear & Heat Stability: Resists viscosity breakdown and thermal degradation in Indian ambient temperatures up to 50°C

✔️ Exceptional Soot Dispersancy: Prevents soot agglomeration, abrasive wear, and cold-sludge buildup

✔️ Active Detergent Chemistry: Neutralizes acidic combustion by-products and keeps pistons free of lacquer and carbon deposits

✔️ Extended Drain Intervals: Sustained Total Base Number (TBN) retention ensures prolonged drain cycles without sludge accumulation
