GC SYNTHETIC SHIELD 5W-40

GC SYNTHETIC SHIELD SAE 5W-40 API SN is an advanced synthetic engine oil engineered to meet the high thermal and mechanical stress of European and Asian vehicles operating in the Middle East. Provides excellent piston cleanliness, oxidation control, and wear resistance under extreme highway driving conditions.

Application Category Recommended Service Life / Drain Interval
Passenger Cars, Luxury Sedans & SUVs 8,000 km – 10,000 km (Optimized for long-distance KSA highway travel)
High-Performance Gasoline Engines 280 – 320 Operating Hours (Sustained thermal resistance)

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

  • Thermal Viscosity Resistance: Prevents oil thickening and thermal degradation during high-speed summer travel.
  • Piston Deposit Control: High-efficiency detergents control carbon formation under continuous heavy loads.
  • Cold-Start Protection: Ensures immediate oil pressure delivery during cool morning ignition.
  • Seal & Elastomer Compatibility: Protects oil seals and gaskets to prevent leaks over long service intervals.
