Product Description

Shell Mysella S3 S 40 is a high-performance quality oil meticulously blended for use in 4-stroke, spark-ignition engines. Designed to meet the specific requirements of gas engines, this exceptional lubricant offers superior protection and longevity. Whether your application involves natural gas, sour gases, or biofuels, Shell Mysella S3 S 40 ensures optimal engine performance and reliability.

Performance of Shell Mysella S3 S 40

• Extended Oil Life: Shell Mysella S3 S 40 significantly prolongs oil life by resisting oxidation and nitration. Its high level of TBN (total base number) neutralizes acids and provides corrosion protection, even when “sour” gases are in use.
• Engine Protection: Formulated with an optimized level of ‘ash’ components, this oil helps prolong the life of valves in engines that prefer a medium ash oil. With a maximum phosphorus content of 300 ppm, Shell Mysella S3 S 40 is compatible with engines equipped with emission catalysts.

Features of Shell Mysella S3 S 40

• Medium Ash Content: Ideal for engines that traditionally require a medium ash oil to protect the valve seating area of the cylinder head.
• Quality Formulation: Crafted to meet the stringent demands of modern gas engines, including those designed to limit emissions of NOx.
• Suitable for Sour Gases: Shell Mysella S3 S 40 performs exceptionally well in engines fueled by sour gases such as landfill, bio, or sewage gas.

Benefits of Shell Mysella S3 S 40

• Enhanced Engine Life: The optimized ash content contributes to valve longevity, ensuring reliable performance over time.
• Emission Compatibility: With low phosphorus levels, this oil is safe for engines equipped with emission control systems.
• Reduced Downtime: Longer oil life means fewer oil changes, minimizing maintenance disruptions.

Specifications & Certifications

SAE Viscosity Grade

• Grade: 40
• Description: Shell Mysella S3 S 40 falls within the SAE 40 viscosity range, making it suitable for various gas engines.

Kinematic Viscosity

• @40°C: 135 mm²/s
• @100°C: 13.5 mm²/s
• Explanation: These values indicate the oil’s flow characteristics at different temperatures. The higher the viscosity, the thicker the oil.

Density

• @15°C: 894 kg/m³
• Significance: Density affects oil circulation and heat transfer within the engine. Shell Mysella S3 S 40 strikes a balance between fluidity and protection.

Flash Point (Closed Cup)

• Temperature: 230°C
• Importance: The flash point determines the oil’s safety during handling and storage. Shell Mysella S3 S 40 has a high flash point, minimizing fire risk.

Pour Point

• Temperature: -18°C
• Explanation: The pour point represents the lowest temperature at which the oil can flow. Shell Mysella S3 S 40 remains fluid even in cold conditions.

Base Number (BN)

• Value: 8.5 mg KOH/g
• Purpose: The BN measures the oil’s alkalinity. Shell Mysella S3 S 40’s optimal BN ensures effective acid neutralization.

Sulphated Ash Content

• Percentage: 0.9% wt
• Significance: Low ash content minimizes deposits and extends engine life.

Phosphorus Content

• Level: 300 ppm
• Role: Phosphorus contributes to anti-wear properties. Shell Mysella S3 S 40 balances protection and emission compatibility.
