GC MULTI-GRADE 10W-30

Description
Download TDS Sheet

GC MULTI-GRADE SAE 10W-30 API SL is a fuel-efficient multi-grade motor oil formulated with quality Group II base stocks and tailored additive chemistry. Designed to provide reliable wear control, sludge prevention, and fluid efficiency under elevated ambient temperatures across Saudi Arabia.

Application Category Recommended Service Life / Drain Interval
Light Commercial Fleets & Passenger Vehicles 5,000 km – 7,000 km (Optimized for urban and highway driving across KSA)
Stationary Gasoline Generators & Field Units 200 – 250 Operating Hours (Depending on ambient dust and heat loading)

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

  • Fuel Economy Efficiency: Lower high-temp viscosity profile reduces fluid drag for optimized fuel consumption.
  • Active Deposit Management: Prevents lacquer, varnish, and carbon accumulation on critical engine valves.
  • Low-Temperature Flow: Rapid oil pressure buildup ensures immediate lubrication upon cold engine ignition.
  • Corrosion Resistance: Neutralizes combustion acids to shield internal engine metallurgy.
