Description
Download TDS Sheet

GC NEXTGEN ULTRA SAE 5W-30 API SQ is a flagship fully synthetic engine oil specifically engineered for the latest generation of hybrid electric vehicles (HEV/PHEV) and modern high-efficiency engines operating under extreme summer heat in Saudi Arabia. Delivers instant fluid film delivery, ultra-low volatility, and outstanding stay-in-grade shear stability.

Application Category Recommended Service Life / Drain Interval
Hybrid Vehicles & Next-Gen Architectures 12,000 km – 15,000 km (Optimized for frequent stop-start KSA traffic)
High-Efficiency Modern Fleets 350 – 400 Operating Hours (Uncompromised protection across desert heat)

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

  • Hybrid System Optimization: Formulated to withstand thermal cycling and frequent engine restarts inherent in hybrid vehicles.
  • Emissions Catalyst Safety: Low-SAPS technology preserves GPF and catalytic converter performance over extended lifespans.
  • Extreme Evaporative Control: Ultra-low NOACK rating minimizes oil breakdown and consumption in temperatures > 45°C.
  • Shear Stability: Maintains optimal oil viscosity under heavy engine load and sustained highway speeds.
