Description
Download TDS Sheet

GC NEXTGEN ULTRA SAE 5W-40 API SQ is a next-generation fully synthetic engine oil engineered for modern high-output hybrid powertrains and heavy-duty passenger vehicles operating in severe desert climates. Offers unmatched thermal resistance, ultra-low NOACK volatility, and low-SAPS exhaust system safety.

Application Category Recommended Service Life / Drain Interval
High-Output Hybrids & Performance Vehicles 12,000 km – 15,000 km (Optimized for extreme KSA climate cycles)
Next-Gen High-Efficiency Engines 350 – 400 Operating Hours (Uncompromised protection)

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

  • Hybrid Restart Endurance: Maintains immediate protective film during frequent hybrid stop-start power transitions.
  • Catalysts & Aftertreatment Protection: Low-SAPS technology guards GPF and catalytic converters from fouling.
  • Ultra-Low Volatility: Minimal oil loss under prolonged exposure to desert ambient temperatures > 45°C.
  • Superior Shear Hold: Resists mechanical viscosity shear under high RPM and continuous heavy loading.
