GC SYNTHETIC SHIELD 10W-40

Description
Download TDS Sheet

GC SYNTHETIC SHIELD SAE 10W-40 API SN is an advanced synthetic blend motor oil formulated to exceed demanding operational standards under extreme ambient heat in Saudi Arabia. Engineered with high-grade synthetic base stocks and an advanced additive suite, it delivers superior high-temperature deposit control, piston cleanliness, and turbocharger protection.

Application Category Recommended Service Life / Drain Interval
Modern Passenger Cars, SUVs & Light Trucks 7,000 km – 10,000 km (Optimized for severe Saudi summer operations)
High-Demand Fleet & Commercial Vehicles 250 – 300 Operating Hours (Under high thermal loads and dust exposure)

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

  • Piston Deposit Control: Superior high-temperature deposit management maintains ring-land cleanliness and compression under extreme heat.
  • Turbocharger Defense: Resists extreme thermal stress and oil oxidation in high-output turbocharged engines.
  • Evaporative Loss Resistance: Low NOACK volatility reduces oil consumption during long distance highway driving across the Kingdom.
  • Engine Seal Integrity: Preserves seal flexibility to reduce oil loss in severe driving environments.
