GC ULTRA SYNTHETIC 5W-30

Description
Download TDS Sheet

GC ULTRA SYNTHETIC SAE 5W-30 API SP is an advanced fully synthetic engine oil engineered to meet the stringent demands of modern downsized, turbocharged gasoline direct-injection (TGDI) engines operating in harsh Middle Eastern desert climates. Provides exceptional protection against LSPI, timing chain wear, and high-temp turbocharger oxidation.

Application Category Recommended Service Life / Drain Interval
TGDI, Gasoline Passenger Cars & Crossovers 10,000 km – 12,000 km (Optimized for severe KSA driving conditions)
Hybrid Powertrains & Downsized Engines 300 – 350 Operating Hours (Sustained thermal resistance under desert heat)

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

  • LSPI Mitigation Technology: Completely protects against destructive Low-Speed Pre-Ignition in modern TGDI engines.
  • Timing Chain Defense: Prevents timing chain wear and stretch for maintained engine timing and performance.
  • Maximized Fuel Economy: Meets ILSAC GF-6A requirements for reduced fuel consumption and CO₂ emissions.
  • Turbo Oxidation Shield: Provides thermal stability against intense turbocharger operating temperatures.
