GC SYNTHETIC SHIELD 10W-30

Description
Download TDS Sheet

GC SYNTHETIC SHIELD SAE 10W-30 API SN is an advanced synthetic blend gasoline engine oil formulated to meet the challenging operating conditions encountered across Saudi Arabia. Blended with premium synthetic and Group II base stocks, it provides excellent thermal endurance, deposit protection, and fuel economy retention during long-distance driving.

Application Category Recommended Service Life / Drain Interval
Passenger Cars, Light Trucks & Crossovers 7,000 km – 10,000 km (Optimized for KSA highway and mixed driving)
Stationary Equipment & Commercial Light Fleets 250 – 300 Operating Hours (Under thermal heat loading)

Note: Actual drain intervals may vary depending on vehicle condition, fuel sulfur levels, severe dust exposure, and OEM engine recommendations.

  • Fuel Economy Efficiency: Low friction viscosity formulation enhances fuel economy without compromising wear protection.
  • Piston Deposit Control: Superior high-temperature detergent package controls carbon deposit formation under thermal stress.
  • Thermal Stability: Resists oil oxidation and breakdown during extended high-speed operation across Middle Eastern highways.
  • Low Volatility: Reduced NOACK evaporative loss minimizes top-up requirements in extreme ambient temperatures.
